Headphones Amps

Years of experience in making high quality headphone amps have been distilled into the design of the MX-HPA. As a result, this fully-balanced headphone amp offers an awe-inspiring listening experience.The MX-HPA’s technical performance is stunning. Typically, distortion from 20 Hz to 40 kHz is less than 0.005%. Signal-to-noise ratio is better than 120dB (‘A’ weighted). Frequency response is ruler flat from 10 Hz to 20 kHz (-0.1dB).The MX-HPA is capable of a short-term peak of 10 watts (for one cycle) and has two gain positions: 18dB (8X) and 24dB (15X). Inputs are either balanced or single-ended. The MX-HPA will automatically convert single-ended inputs to balanced. The MX-HPA is genuinely fully balanced from beginning to end.Specifications:OutputPower 1.8 Watts per channel into 8 Ohms (27dBW)Maximum output voltage 19 Volts RMS, 20Hz to 20 kHzOnset of clipping (54 Volts peak-to-peak) balancedLine inputTHD+N >0.005% typical, 20Hz to 20 kHzSignal / noise ratio >120dB ‘A’-weightedInput impedance 50k OhmsFrequency response +0, –0.1dB, 10Hz to 20 kHzGain, LO position (volume max) 18db (8x)Gain, HI position (volume max) 24dB (15x)ConnectionsLine level inputs1 pair line level XLR (balanced) connectors1 pairs line level RCA connectorsHeadphone outputs1 pair 3-pin XLR/¼” stereo Jack combined socketsPower requirementMains voltages 90-250VAC 50-60Hz universal worldwide supplyConsumption >0.25 Watts standby (Orange LED lit)15 Watts maximum (Blue LED lit, full power output)GeneralDimensions - WxHxD (mm): 220 (82/3”) x 53 (2”) x 240 mm (9½”)Weight (unpacked / packed): 2.2 kg (5 lbs) / 3.7 kg (8¼ lbs)

The MA400 features XLR Thru jacks and provides superb noise-free operation. Just connect your mic to the Mic Input and send a line from the Mic Thru to your main mixer. You can even use studio-grade condenser mics, as the MA400 will pass +48 V phantom power, if your mixer is so equipped. The Phones jacks accept both 1/4" and 1/8" headphone and earbud connections, making the MA400 ideal for hardwired IEM (in-ear-monitor) applications, such as singing drummers and keyboardists. The MA400 comes with a dedicated 12 V DC power supply and an LED to indicate when it is powered up.Capable of stereo or mono operation, the MA400 is a powerful little mixer that allows you to control two independent sources, a microphone and the monitor feed from your main mixer. Simply adjust the Mon Level control to a comfortable setting and then dial in all the “me” you want with the Mic Level control.

4-channel stereo headphone amplifier for use with all types of headphonesFour high-power stereo amplifiersHighest sonic quality even at maximum volumeOutput level control for each channelUltra low-noise 4580 operational amplifiers for outstanding audio performanceDC 12-Volt adapter includedHigh-quality components and exceptionally rugged construction ensure long lifeConceived and designed by BEHRINGER Germany Mini to the max! You can use this super-compact stereo headphone amplifier with practically all headphones—four of them at the same time, to be exact! For example, you can let up to 4 different people in your studio listen to the main mix while the recording is being made, and each listener can determine his own volume level using the dedicated output level controls. The HA400 contains 4 high-power stereo amplifiers that maintain the highest sonic quality even at maximum volume levels. Ultra low-noise 4580 operational amplifiers are included for outstanding audio performance—these are the same op amps found in “full-size” audio equipment—plus, a DC 12-Volt adapter is included.If you are one of those musicians who like to deck out their equipment with lots of bells and whistles, the HA400 definitely makes a great addition to the functionality of your studio.

Compact, Portable Headphone Amp / DAC / PreampThe m900 is a portable, desktop friendly headphone amplifier / DAC / preamp combo designed to give audio professionals and enthusiasts musical and transparent audio playback from USB, S/PDIF or TOSLINK sources. For small DAW studio setups, portable laptop editing or mixing rigs, or just pure playback enjoyment, the m900 provides the same analog and DAC quality as our large monitor controllers, but in a rugged, portable and surprisingly affordable unit.The m900 DAC uses the latest generation AKM 4490 chip, which features 32-bit processing and supports sample rates up to 384kHz PC or 256x DSD. The USB interface operates in asynchronous mode allowing the m900 to be the clock master which makes the system immune to USB bus jitter. S/PDIF and Toslink inputs allow the m900 to enhance to any DAW interface with true reference quality D/A conversion, headphone monitoring and stereo speaker control.An intelligent power supply design allows for two power operation modes - LOW and HIGH. LOW power mode is from USB connector #1, which provides bus power along with data, allowing the m900 to operate from a single connection to your computer. HIGH power power mode is available by connecting the included 2A USB DC power supply to the USB connector #2, which provides additional power harder to drive headphones.Transimpedance amplifier topology coupled to a zero ohm output impedance driver provides headphone performance that is incredibly spacious and transparent with a tight, enveloping low end. Our latest generation crossfeed circuit rounds out the design by simulating an acoustic listening environment in the headphones. Familiar tracks become new again with surprise details, while audio production tasks like tracking, mixing and editing happen faster and easier.After many years of honing our DAC and headphone amplifier designs, the m900 distills the best of what we've learned in a compact, rugged and simple unit. Weather in the studio, on your desk or on the road, the m900 will bring you closer to the music you love. Features:USB, S/PDIF and Toslink digital inputs, supports up to 192kHz (Toslink up to 96kHz)Asynchronous USB interface for jitter free computer audio playback, supports up to 384kHz PCM and 256x DSDDual zero ohm output impedance headphone outputsUnbalanced level controlled outputs via RCA for connecting to a stereo monitor systemCompact, portable chassis perfect for travel, desktop or studioLow power mode via USB Bus powerHigh power mode via included USB 2A power supply4 different DAC filter settings to tailor playback performance to personal preferenceSimple user setup menu for setup and calibration7 segment LED display displays level and setup menu informationLarge rotary encoder for volume control and setup menu navigationMade in Lyons, CO USA5 year transferable Warranty

Tired of straining to hear underpowered headphones? The PreSonus® HP4 headphone-distribution system is louder than you're ever likely to need for session and stage use. (Be careful with that level control!) Yet the sound is clear and clean, with a wide dynamic range. At last, everybody will be able to hear!Simplicity is the HP4's hallmark. It offers left and right line inputs, left and right line outputs with level control, and four headphone outs. You can sum the stereo signals to mono, adjust the individual headphone levels, and mute the rear-panel Monitor outputs while leaving the headphone outputs active. So while the HP4 is simple to set up and use, it has all the features you need to create a versatile headphone system.The compact HP4 can sit on a tabletop or can be screw-mounted to a standard rack tray (not included), where it requires just one-third of a rackspace. If your needs grow, you can use the line outputs to feed the inputs of a second HP4 or the larger HP60 headphone amplifier.So quit struggling with mediocre headphone amps. Get the PreSonus HP4 and hear everything loud and clear. You owe it to your music.Features4 screaming-loud (130 mW per channel) stereo ¼-inch headphone outputs (front panel2 balanced ¼-inch line outputs (monitor outputs)2 balanced ¼-inch line inputsHeadphone level control for each channelMono summing switch for each channelMonitor level control and mute switchDaisy-chain multiple units via monitor outputsCompact 1/3U rack-mount chassisSealed, detented, metal rotary controlsExternal 16 VAC power supply
