From the high-performance D/A converters to the massive toroidal-core power transformers, each element is configured for single channel processing.High-quality wireless audio streaming via Bluetooth®In addition to conventional SBC and AAC codecs, the UD-505-X also supports LDAC™ (24bit/96kHz Hi-Res audio transmission), and Qualcomm® aptX™ HD, a codec that uses 24bit/48kHz format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly.Up-conversion up to 384kHz/32bit PCM and 24.5MHz DSDEmploying RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the UD-505-X up-converts PCM digital signals up to 384kHz/32bit PCM and 24.5MHz DSD. With the up-conversion function activated, you will hear an improvement in quality, even with music that you are familiar with.Dual high-capacity toroidal-core power transformersThe dual monaural theme continues. Two over-sized high-capacity toroidal-core power transformers are employed in the UD-505-X, supplying stable, individual current sources for each of the left and right channels. This means neither channel will be affected by changes in the power consumption of the other during digital processing.Analog output circuits have been further refinedImproved TEAC-HCLD2 enhanced-current output buffer amp circuitWe employed the TEAC-HCLD 2 for the analog output circuit. This is a further improved version of the TEAC-HCLD circuit enhanced-current output buffer amp that increases crucial current output capacity (HCLD: High Current Line Driver).

This electronic volume control is a variable gain amp type comprised of four discrete circuits for left, right, positive and negative (L+, L?, R+, R?). By placing the variable gain amp volume control, which processes in analog, in the audio signal path on the circuit board, issues with noise resulting from diverging wiring are avoided.Designed to bring out the maximum potential of your headphonesThe UD-505-X's headphone amplifier circuit provides balanced-drive by using the TEAC-HCLD2 circuit, – comprised of four output transistors for each left and right channel – for headphone output. With challenging 600Ω high-impedance headphones for example, the UD-505-X allows you to bring out the potential of these type of headphones.Active-ground drive offers a new headphone drive modeThe active-ground is a new driving mode that employs the principles of balanced connection. It forcefully drives the ground, by lowering the ground level to 0V, providing an ideal ground condition (rather than just connecting to the conventional ground). This means it also suppresses hum noise from the power supply and enhances the purity of silent pauses by lowering the noise floor. Subtle detail, such as the breathing of artists and the textures of sounds, will feel even more convincing.Symmetrically laid out XLR and RCA output jacksThe UD-505-X is equipped with both balanced and unbalanced Analog audio outputs.

The headphone amplifier, monitoring controller and DAC with 120V technology Phonitor 3 DAC is not only the ultimate headphone amplifier and monitoring controller with 120V technology – the integrated DAC makes it the perfect monitoring centerpiece for demanding producers as well as sound and mastering engineers working with digital sources or in the DAW. Whether if USB, AES/EBU or S/PDIF – the integrated DAC with analog SLP120 converts digital PCM audio signals with a resolution of 32 bit and a sampling rate of up to 768 kHz. It converts DSD signals with a resolution of up to DSD256. On the analog side, the Phonitor 3 DAC, based on the SPL 120V technology, offers the same monitoring quality as the big SPL mastering consoles – on loudspeakers and headphones. The analog Phonitor Matrix allows mixing and mastering on headphones in the highest quality – with the same spatial perception of the stereo stage as on loudspeakers.Great sound – for headphonesThe Phonitor 3 DAC offers connection for a standard headphone with a stereo jack plug on the front. Thanks to the enormous output power, all kind of headphones are driven effortlessly. Thus, it plays out the advantages of the SPL 120V technology and rewards the listener with an honest, detailed and at the same time vivid sound experience.Great sound – also for loudspeakersOn the rear of the device, Phonitor 3 DAC offers a stereo output which makes it a high-quality monitoring controller for any monitoring situation. Active speakers with an integrated power amplifier or passive speakers in combination with a power amplifier can be connected at this output.Monitoring at the highest levelPhonitor 3 DAC offers the same key technology – SPL 120V technology – and signal quality as the big SPL DMC and MMC mastering consoles.Headphones or SpeakersThe Output switch – simply switch from headphone to speaker playback. In the center position (Mute), no signal reaches the outputs. The VU meters light up red.Digital & analog stereo inputs – free choiceUp to six stereo sources can be connected to the Phonitor 3 DAC. The source is selected via the Source switch.Analog inputsOn the analog side, two analog stereo inputs are offered, each with two XLR line inputs. Professional analog players with balanced outputs and line level can be connected here.Digital inputsOn the digital side, the Phonitor 3 DAC offers four digital stereo inputs.USBThe USB input (type B) can be used to directly connect the DAW. No driver installation is required for operation with a Mac or an iDevice. Via USB, the Phonitor 3 DAC converts PCM audio signals with a resolution of 32 bits and a sampling rate of up to 768 kHz as well as DSD signals with a resolution of up to DSD256.S/PDIF, coaxialThe Input S/PDIF coaxial can also receive a two-channel signal (PCM audio) with sampling rates up to 192 kHz and a bit rate of 16 bits to 24 bits. Unbalanced, 2-wire 75-ohm coaxial cables with RCA connectors are used for signal transmission.S/PDIF, opticalThe S/PDIF optical input can also receive a two-channel signal (PCM audio) with sampling rates of up to 192 kHz and a bit rate of 16 bit to 24 bit. The input jack is an F05 jack. This interface is better known under the Toshiba brand name TOSLINK.Tip: You should attach importance to the quality of the optical fiber. With inexpensive plastic optical fibers, transmissions with quad sampling rates (176.4kHz/192kHz) may have faults. In this case a glass fiber optic cable should be chosen.AES/EBUThe AES input provides an input jack which corresponds to a standard XLR input (XLR, female). An AES signal can transport two encoded PCM audio channels with a maximum sampling rate of 192 kHz and a bit rate of 16 bits to 24 bits. This standard is defined under IEC 60958 Type I. Balanced, 3-core, 110 Ohm “twisted pair” cables with XLR plugs are used for connection.The DAC – the best is just good enoughThe converter chip in the Phonitor 3 DAC´s digital-to-analog converter is the highly acclaimed AKM AK4490 Velvet Sound™ premium DAC chip, which thanks to its architecture reproduces the finest sound details. It converts PCM audio at 32-bit resolution and a sampling rate of up to 768 kHz, which is 16 times the resolution of a CD. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256.SLP120The analog output of any DAC chip must be filtered by a low pass filter when entering the analog world. In contrast to all other DACs in the world, the low pass filters here are built using SPL 120V technology, which provides a plus in dynamics and headroom and sound. The DAC in the Phonitor 3 DAC is equipped with the SLP120 – an analog “single low pass” filter with 120V technology.Milled from solidThe massive 45mm volume control knob milled from aluminum is a haptic highlight. Its mass together with the Alps RK27 “Big Blue” potentiometer enhances the “spoon in the honey” feeling even further and provides perfect control of the monitoring level.Monitoring without any compromisesThe Phonitor 3 DAC is a full-fledged monitor controller:Source selectionPhonitor Matrix with Crossfeed, Speaker Angle and Center Level (the latter can be switched off)Mono/StereoLaterality controlSolo L/RPhase inversion for L and RL/R SwapOutput switchable to headphones or speakersMuteMono or stereo – a matter of settingThe Mono/Stereo switch can be used to select whether the output signal of the Phonitor 3 DAC is a regular stereo signal or whether it is summed to a mono signal.Finding the real centerNaturally, hearing can be directed more to the left or more to the right. This becomes particularly clear when listening on headphones. Therefore, the Phonitor 3 DAC has the uniquely finely resolved laterality control, which rebalances the stereo image on the monitoring side. The Mono/Stereo switch can not only be used to switch between stereo or mono playback. This switch is also used to activate or deactivate the laterality control.Solo L/ROnly the right or left channel of the audio signal should be played back? The Solo L/R function makes it possible. If the triple selection switch is in the “L” position, only the left channel is played back – if it is in the “R” position, only the right channel is played back. In the middle position “Off” the Solo function is switched off. The regular stereo signal consisting of the left and right channel is thus present at the output of the Phonitor 3 DAC.L/R SwapA special feature is the channel swap function: L/R Swap. This function inverts the stereo image. Left becomes right and right becomes left. This is especially important and extremely time-saving, when you are monitoring samples in video dubbing that should match a scene with direction of movement. If the direction is not correct, you usually have to load the sample into the DAW to switch channels. before you can judge whether the sample matches the image. With the L/R Swap function, this is no longer necessary. You can now adjust the direction of movement on the Phonitor 3 DAC while pre-listening the sample library.Phase inversion for L and RWith this switch the phase of the left or right channel of the audio signal can be inverted. If the three-way selection switch is in the “L” position, the left channel is inverted – if it is in the “R” position, the right channel is inverted. In the middle position “Off” this function is switched off. At the output of the Phonitor 3 DAC the regular stereo signal is thus present.M/S – Mid or Side?By using the mono/stereo and L/R phase inversion switch in combination, it is also possible to only monitor the mid or side signal. When the switch is set to “Mono” and phase inversion is active for L (or R), only the side signal is played back. If the phase inversion is switched off, the mono signal corresponding to the “M” signal is played back. Separate monitoring of the M and S signals has become a widespread standard for many mixing and mastering engineers.Everything at a glanceTwo mechanical VU meters visualize the input levels for the left and right audio channels. The “VU Cal” switch can be used to reduce the signal visualized on the VU meters by -6 dB or -12 dB. Thus, the VU meters operate in the ideal display range even at very high input levels.The Revolution: Phonitor MatrixThe Phonitor Matrix is the revolution in the headphone amplifier.One of the unique features of SPL headphone amplifiers is the SPL Phonitor Matrix. It enables mixing and mastering engineers to create perfect mixes on headphones, which will translate perfectly to all types of stereo speaker systems. But the Phonitor Matrix is not only designed for professional use in the studio. It also enables the hifi enthusiast to enjoy music on headphones, like if it was played back on speakers.How is this possible?Music is normally produced and mixed for playback on stereo speakers. Listening on headphones is different from listening on loudspeakers. The biggest difference is the lack of crossing signals of the sound signal from the left speaker to the right ear and from the right speaker to the left ear.These crossing signals are missing in conventional headphone listening, because there are no signals crossing from one side of the headphones to the other. This results in an unnaturally wide stereo stage and sound sources are not played back at their actual position in the stereo spectrum. The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry.Summed up:The SPL Phonitor Matrix corrects the false representation of the stereo sound image, which makes it much easier to find the right decisions for mixing and mastering engineers. The hifi enthusiast can experience the music, like it was originally mixed and recorded. So nothing stands in the way of a successful and long mixing session on headphones.Preamp Out or Direct OutWith a DIP switch on the rear of the device, the volume control for the rear stereo output can be switched out of the signal path. But that’s not all. It is also possible to output the Phonitor Matrix to the stereo output on the rear panel of the device – regardless of whether this is configured as Preamp Out (with volume control) or Direct Out (without volume control).More powerIf headphones have a rather low sensivity – no problem. With DIP switch 1 on the rear of the device, the level at the headphone output can be increased by 12 dB.Sounds goodWith all SPL devices we develop not only according to plan, but also by ear. All important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.The 120V technologyThe 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps.

DescriptionThe ZEN Air CAN is a powerful, hi-res home analogue amplifier that provides greater headphone enjoyment with any analogue source such as your PC, Mac, smartphone, tablet, streamer or TV.Amp it upThe ZEN Air CAN is an amplifier pure and simple.It simply takes an input signal from a source such as those mentioned above and creates a larger copy of the original signal before it’s sent to your headphones. Think about listening to sound with your hands over your ears and then removing them! Adding the ZEN Air CAN into your system is a little like that – back comes clarity of sound as well as volume.Lots to gain…The ZEN Air CAN comes with three gain settings so that it works well with every pair of headphones or in-ear monitors (also known as IEMs). What is gain? Gain in audio terms refers to an amplifier’s ability to increase the amplitude (size) of the signal from the source (input) to the headphones or speakers (output). More gain equals a stronger signal. You will need to adjust the gain depending on the sensitivity of the headphones or iEMs you are using. For example, highly sensitive headphones need lower gain. Play around with the settings. Trust your ears.eSpecially for youThe ZEN Air CAN has two different headphone sockets – 6.3mm single-ended and 4.4mm S-Balanced. There are basically two types of headphone – single-ended and balanced. In a nutshell, single-ended is the most common but the balanced option is often considered the better as it offers more power and control of the headphones. At iFi, we know not everyone has balanced headphones, so we’ve created our S-Balanced technology. This gives you all the benefits of a balanced connection – lower noise, less crosstalk – but without the need for balanced headphones.Sonic tailoringThe ZEN Air CAN boasts a couple of sonic tweaks, unique to iFi. XBass is analogue bass boost. In other words, it extends the bass response to suit different headphones. XSpace is an analogue headphone spatialiser. This opens up your music to give you the spaciousness of a live-concert atmosphere.TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.They are pricey but are a perfect addition to our products.Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates.

The ZEN CAN Signature 6XX analogue headphone amplifier takes sonic tailoring to the next level with ActivEQ. ActivEQ This new feature, called ActivEQ, combines active and passive components to create a specific EQ curve to suit a particular pair of headphones, performed in the analogue domain without a hint of additional noise or distortion. The ZEN CAN Signature 6XX, features ActivEQ for the ‘MassDrop x Sennheiser HD 6XX’ – a popular pair of high-quality headphones with more than 120,000 sold to date, based on the Sennheiser HD 650 and created exclusively for Drop.com. These headphones are renowned for the quality of their midrange performance but exhibit some quirks in the bass and treble regions, which can be seen in frequency response measurements. EQ. Activated. When the ‘HD 6XX’ button is pressed, the ZEN CAN Signature 6XX calibrates its signal to complement the headphone’s response characteristics right across the frequency range, thus tailoring its performance to precisely fit the HD 6XX like a made-to-measure suit. In particular, the 7kHz treble and bass below 500Hz is gently elevated. What’s more, the benefits of this ActivEQ curve are equally applicable to the Sennheiser HD 650, which shares the same characteristics. It also has an effect on other Sennheiser models – take a look here. This feature can be switched on or off. Without ActivEQ engaged, the ZEN CAN Signature 6XX’s performance is adroitly balanced to make the most of all manner of headphones and in-ear monitors. No pain, just gain. The ZEN CAN Signature 6XX features four gain settings in six dB steps – 0dB, 6dB, 12dB and 18db. This enables the amp to precisely suit the connected headphones. Unity gain (0dB) is useful to ensure low noise with sensitive in-ear monitors, while the higher gain settings make the most of tougher headphone loads, delivering excellent dynamic headroom. XSpace This analogue processing mode compensates for the ‘in-head localisation’ effect that can occur when using headphones to listen to music that was mixed using a pair of speakers. It widens the headphone soundstage to deliver a more spacious and speaker-like experience. Balance of power The ZEN CAN Signature 6XX’s circuitry is a balanced, symmetrical dual-mono design – a topology usually reserved for high-end headphone amps – with a number of key elements trickled down from the discrete Class A circuitry developed for iFi’s flagship headphone amplifier, the Pro iCAN. Key components have been upgraded to enhance performance in line with the improvements made to the ZEN CAN Signature 6XX, including the use of Panasonic OS-CON and Elna Silmic II capacitors. Driving force The amp offers prodigious drive capability, delivering 1600mW (7.2V) into 32 ohms from the single-ended output, with 15V+ available to loads of 300 ohms or more through the balanced output, ensuring it takes even current-hungry planar headphones in its stride. Delivering ultra-low distortion, rich sonic detail, engaging dynamics and the ability to drive all manner of headphones with ease, the ZEN CAN Signature 6XX is a truly a driving force to be reckoned with. Stay connected The ZEN CAN Signature 6XX offers stereo RCA and 3.5mm single-ended inputs, plus a 4.4mm Balanced input. A 4.4mm balanced output is also provided, to connect to power amps equipped with a balanced input. It provides a pair of headphone outputs – a 6.3mm output for headphones that have a standard single-ended connector (compatible with all headphones) and a 4.4mm Balanced output for headphones offering balanced connection. An increasing number of high-quality headphones and in-ear monitors either come so equipped or give the option of detaching the cable and upgrading to a 4.4mm Balanced connector, and this output makes the most of them (it is particularly recommended for high-impedance headphones). Dynamic Duo The ZEN CAN Signature 6XX works well with the ZEN DAC Signature V2. Products can be bought separately but a ‘ZEN Signature Set’ is now available. This comprises both ZEN Signature units plus a high-performance 4.4mm Balanced cable (worth £69 when purchased separately) to connect them together. When used in tandem, the two ZEN Signatures make a fantastic, desktop-sized headphone system for both digital and analogue sources, further extending the reputation of iFi’s ZEN Series for delivering exceptional performance and versatility at remarkable prices.

The tiring super stereo effect is a thing of the past.Enjoy your music without listening fatigue and exactly the way it should be heard.Music is normally produced and mixed for playback on stereo speakers.Listening on headphones is different from listening on loudspeakers. The biggest difference is the lack of crossing signals of the sound signal from the left speaker to the right ear and from the right speaker to the left ear. These crossing signals are missing in conventional headphone listening, because there are no signals crossing from one side of the headphones to the other. This results in an unnaturally wide stereo image and the various sound sources of the audio signal are not localized as the sound engineer intended them to. This effect is often referred to as “super stereo effect”. During conventional listening on headphones, our brain can balance the false representation of the playback to a certain extent – but this is very exhausting.The SPL Phonitor Matrix can correct this false stereo image with an analog circuitry. The Phonitor Matrix therefore not only ensures a correct representation of the stereo image, but also a relaxed listening experience.The two main parameters of the Phonitor Matrix are Crossfeed and Angle:Crossfeed determines the crossing signals of the channels, the so-called interaural level difference.Angle determines the opening angle of the stereo image, the so-called interaural time difference.Center of AttentionTo make the listening experience even more perfect, the level of the center of the stereo image needs to be attenuated when the Phonitor Matrix is active. This ensures that not only the position of all sound sources is correct but also their volume.In the Professional Fidelity Phonitor devices this value is set to a fixed attenuation of -1 dB, which is the best choice for getting an authentic representation of the sound stage.Sounds good!With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. All important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.The VOLTAiR TechnologyThe 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.The highest possible audio quality requires the highest possible audio operating voltage.The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
