Radial

The Radial Trim-Two is a passive direct box, designed for use with laptop computers and other consumer devices where the user has a requirement for a 'ready access' volume control for quick adjustments on stage.The design begins with a choice of inputs including dual ?" jacks, left and right RCAs and a stereo 3.5mm input. These are wired in parallel to allow the signal to be split off to feed an alternate signal path such as monitors. Inside, two great sounding Eclipse transformers do the work of isolating and balancing the signal. These 'passive engines' deliver a linear frequency response from 20Hz to 18kHz and are capable of handling up to +15dB signal levels thus providing typical -10dB consumer-level devices with plenty of headroom. An easy access front panel stereo level control makes adjusting the volume a snap. A handy stereo-to-mono switch makes it easy to reduce the output channel count or send the same balanced signal to two destinations at once. Transformers provide galvanic isolation between the source and the destination and are extremely effective at eliminating hum and buzz caused by ground loops. This is augmented with a ground lift switch at the XLR outputs. One merely connects the source to the Trim-Two and then the male XLR outputs to the PA system. As the Trim-Two is completely passive, no power is required.Made in Canada from heavy duty 14 gauge steel, the Trim-Two features Radial's unique book-end design that creates protective zones around the connectors and controls. Inside, the unique I-beam frame protects the sensitive inner workings from potential damage that could torque the PC board and cause solder pointes to prematurely go cold. The steel casing also provides shielding against external magnetic fields.These features make the Trim-Two a great choice for keyboard players, DJs, audio-visual presenters and others that employ a laptop or tablet with a handy volume contro

The Radial Phazer™ is an analogue phase alignment tool that lets you bring two sound sources together so that the fundamentals play in sync. Once in phase, the results are impressive: On electric guitar; you can combine the direct feed of an amp with a room mic to create fat rich tones. On a kick drum, combine the 'attack' sound from a batter head mic with the 'boom' captured by the outer shell mic. On a snare drum, combine the top and bottom mics and on acoustic instruments, combine a close 'spot' mic with a room mic to capture textures like never before.The Phazer is designed from the ground up for optimum sound quality. It employs full-size 100% discreet class-A electronics to deliver the warmth and thickness that is simply not possible with chip based devices. This results in smooth, natural sounding phase curves which are particularly noticeable in the lower frequency spectrum. 0º to 180º phase adjustment is performed with a single knob making it easy to zone-in on the sweet spot. For the more adventurous, a 180° polarity reverse switch accesses the 181° to 360° range and lets you create weird to absurd 'Phazed' tonal textures. This is augmented with a variable low-pass filter that lets you focus the effect in the lower frequency spectrum - where phasing is most audible.Built Radial tough for the road, the Phazer is equipped with an innovative book-end design that creates a protective zone around the knobs and switches. Construction is 14-gauge steel with an internal I-beam frame that protects the sensitive electronics in even the harshest touring environments.

The Radial Tonebone Mix-Blender™ is a multi-function pedal that lets you mix two instruments or effects together and then send the combined signal through a mixer-style effects loop for processing. Designed to work with guitar, bass and keyboards, the Mix-Blender begins with two high-performance Class-A buffers for maximum fidelity.  These lower the impedance to drive the signal further without noise. Individual volume controls on each channel let you mix the two inputs to suit and can be used to blend two pickups on an acoustic guitar, combine two pedals in parallel such as a chorus and a distortion, or to have two different instruments 'live' on stage – each set with the same output for quick changeovers. The signal can then be routed to a true 'mixer-style' effects loop and activated using the on-board footswitch. This features a wet-dry blend control that lets you mix-in effects pedals with precise control to add slight enhancements or extreme coloration to the signal chain. In other words, the Mix-Blender lets you retain the original sound of the instrument and add in as much of the effect as you like.  Think of adding a touch of overdrive to a bass guitar without losing the bottom end. How about mixing in some distortion to your acoustic guitar to give it more shimmer? How about adding a chorus or phase shifter to your Hammond synth patch? The Mix-Blender is a unique tool that is designed to bring new tonal textures to your world and enhance your creative inner spark. Features:Mix two instruments or effects together at same timeBlend in effects while retaining the tone of your instrumentClass-A buffered inputs with individual level controlsOpens door to creating subtle or unique effects 

The Bones Vienna Chorus is a dual-mode chorus pedal that mimics the effect of a Leslie rotating speaker by allowing the guitarist to instantly transition between a moderate choral to an intense vibrato with the stomp of a footswitch. This can be particularly useful when switching the chorus between a verse and a bridge to create lush and exciting effects.Unlike today's common digital chorus pedals, the Vienna is 'old school'. The distinctive warm tone is captured by way of a new-old-stock (NOS) Panasonic MN3007 - circa 1976 bucket brigade chip from the early days of analog delay & chorus pedal development. What makes the Vienna particularly impressive is that unlike older analog chorus pedals that were plagued with noise and hiss, the Vienna is quiet. In fact so quiet it rivals today's digital alternatives. This means that tone aficionados can finally rejoice with the character and feel of a vintage chorus pedal without the noise. Both chorus channels are equipped with individual rate and depth controls for full 2-channel performance. The effect is augmented with 'turbo mode' which introduces a proprietary oscillator waveform frequency while increasing the range. This lets you transition from a slight choral to extreme warble, tremolo or vibrato - opening the door to explore new sonic landscapes.Optimized for pedalboards, the Vienna is super compact and employs 9V powering to suit the various DC power bricks that are now common with multi-pedal systems. (Power supply is not included). To keep mayhem under control, full size LEDs provide high-visibility status indicators for dark stages. And like all Radial products, the Vienna is built 'tough' with 14 gauge steel and baked enamel finish to handle the rigors of professional touring.

The Radial StageBug SB-4 is a compact active direct box that has been optimized for use with piezo transducers. This enables violin, dobro, mandolin, cello, upright bass and other instruments that are best amplified using a piezo to be connected without compromising the tone or frequency response.The design begins with a ¼" input for the instrument pickup. Unlike typical direct boxes that have a 1meg-ohm input impedance, the SB-4 features a very high 5meg-ohm impedance that smoothes out troublesome peaks that give piezos a bad name. The higher impedance also broadens the frequency response for a more natural and pleasing sound. The active circuit performs the high-to-low impedance conversion and balances the signal to enable long runs upwards to 100 meters without loss, delivering spectacular linearity and low distortion throughout the audio range.To help eliminate feedback on stage, the SB-4 is equipped with a high-pass filter and 180° polarity reverse switch. The high pass filter eliminates excessive bottom end which in turn reduces resonance that can cause the top of the instrument to vibrate. The 180° polarity reverse helps reduce acoustic hot spots on stage by changing the phase relationship between the PA system and room acoustics which can combine at certain frequencies to create peaks. Reversing the polarity eliminates the acoustic peak without resorting to severe equalization which only serves to compromise the natural tone of the instrument. Connections include an AUX out for a stage amplifier plus a standard XLR output to feed the PA. Power is derived from the console's 48V phantom, thus eliminating the need for batteries or external supply. One simply connects, turns on the phantom power and plays.Features:Active DI optimized for piezo transducersSmoothes out peaks, eliminates squawkHigh pass filter eliminates resonanceUltra compact to fit in your guitar case
