During Motown’s heyday, a major technical component of “The Detroit Sound’ was the direct input box (DI). Designed by a young Motown audio engineer in the early 1960s, the musicians plugged straight in and achieved a distinct, colorful distortion that would become recognizable all over the world. The DI box was adopted by such Motown greats as James Jamerson Sr., Dennis Coffey and Bob Babbitt, who defined the sound of a generation with their soulful playing and crisply captured notes. Recreated by Acme Audio, the new Motown D.I. WB-3 brings the exact character as the original DI box. Modern updates include the improved variable attenuated for high-level input and the custom-made, rugged steel case (the original DIs were built in Aluminum boxes). Owners of the Motown DI will find that it increases sound quality in a marginal acoustic environment, for the cleanest, purest sound source possible.

CoDI is a two-channel USB audio interface with balanced XLR audio outputs and a transformer isolated USB connection. CoDI was developed to enable high-quality, interference-free transmission of audio signals from a computer to a professional sound system. Interference, hum, poor transmission quality or too low output level of standard sound cards belong to the past with CoDI. CoDI is developed as a plug & play interface and works with the standard drivers of the respective operating systems.

Avenson Audio IsoDIBuilding on the circuitry of the SmallDI, the IsoDI adds two optional isolation stages.The main signal path is still a clean, wide bandwidth transformerless FET amplifier, but the power is generated with an isolated DC to DC converter so that you can have true ground isolation and still run the IsoDI on phantom power.The IsoOut jack can be a buffered, transformer isolated output to feed amplifiers or other inputs that can compromise the performance of the main signal path if connected in parallel. Now there is a way to get a clean DI signal even when there is bad stage power that causes the amp to buzz from light dimmer hash! The switchable IsoOut / Parallel jack give you the flexibility to configure the jack as a summed input, a parallel connected output, or a transformer isolated output.All of this in a rugged palm sized aluminum extrustion that makes it easy to toss into your gig bag or pack into a road case.

The IsoGtr expands on our circuitry of the IsoDI by adding 3 additional transformer isolated instrument outputs to serve as an isolated signal splitter for sending your guitar or instrument signal to up to 4 amplifiers or effects chains (3 transformer isolated + 1 Buffered Main Output), our same ultra-clean wide bandwidth unity gain FET Buffered DI output (XLR), as well as an XLR Line input for Re-amping to any of the available instrument level outputs, all powered conveniently with an external DC power supply. Housed in an extremely rugged 3.33″ x 5.25″ anodised aluminum extruded box (you know… the same type as our IsoDI that we ran over with a van to test under the most extreme tortures of the road). Built with high quality Neutrik TRS and XLR jacks, the IsoGtr will not only be a piece of gear you can trust to perform flawlessly on stage, but also a welcomed high quality part of your signal chain in any professional recording studio.

Avenson Audio Small DIThis phantom powered active DI is the perfect instrument interface.  It transparently passes the sound of your instrument to the preamp without adding its own sound.The Small DI has a very  high impedance input FET buffer inside designed for wide bandwidth and clean reproduction.  The buffer circuit runs on +48V phantom power and is unity gain. One of the best features of the Small DI is that it comes before the preamp, so that your input signal uses all the electronics of the preamp.  The Small DI is also the perfect accessory for microphone preamps that don't have a DI.  Its also great for preamps that put the DI input in an inconvenient place like the back!   It's not much bigger than an XLR connecter and at only 3.25" long it fits anywhere unobtrusively.  The red LED tells you when phantom is turned on making last minute troubleshooting easier.SpecificationsTopology     transformerless FETInput Impedance     10 MΩInput Overload Level     +12 dBu at 1% THDGain     -0.2 dBFrequency Response     10 Hz - 100 kHz (+0/-0.25 db)Signal to Noise (A-weighted)     ≥ 108 dBOutput Impedance     150Ω (load ≥ 1kΩ )Power Requirements     P48 phantom power (~5 mA)Weight     81 g For more information, please visit this products webpage.

Baby Makes Three. In a few short years, FELiX and AliX have become the preamps of choice for discerning touring and recording musicians. From Banjo to bass players, they enable performers to perfect their stage and studio sound beyond what was previously possible. And now directly from this lineage comes BiX, which shares the exact same DNA of its bigger siblings, but with an intelligently streamlined feature set and a price that puts it in reach of any performer, whether on their way to the local coffee shop or the megadome. Controls are dead simple – input gain, high and low shelving EQ, and a 10dB variable boost circuit, with footswitches for mute and boost. I/O includes the instrument input, separate send and return insert jacks, an unbalanced line output, and a balanced ISO DI output on XLR. For enhanced EQ control, rear panel DIP switches select between two different transition frequencies for both High and Low controls. And BiX is pedalboard friendly, with a 9VDC power input and a compact, rugged low-profile chassis. Sonically, BiX is a carbon copy of its bigger siblings, with crystal clear, ultra-quiet audio performance. A better than 30VDC internal operating voltage provides for incredible headroom. The highs are smooth and open, and the lows are deep and rock solid. The dynamics and tone of the instrument come alive with clarity and realism, which translates to creating a deeper bond between you and your instrument. 1/4" high impedance input Separate FX send and return 1/4" unbalanced line output Balanced XLR DI transformer iso output 10dB variable boost Mute and Boost footswitches High and Low shelving EQ Selectable EQ transition frequencies 9VDC operation Over 30V internal operating voltage Pedalboard friendly design 5 year transferable warranty Made in the USA

IBP Analog Phase Alignment Tool line/instrument selects between the line level xlr input on the rear (unity gain) and when pushed in the instrument in on the front (hi Z 10M with gain) for using as a direct box. Earth lift lifts the ground (pin 1)of the output xlr. Phase adjust bypass does just that, bypassing all phase adjust circuitry and allows you to use the IBP without phase adjust, as an active DI or when using the line input, a transformer isolated line driver. Phase invert is a simple polarity reversal as you would find on a mixing console out is 0 degrees, in is 180 degrees. Phase adjust 90 degrees /180 degrees selects between two stages (button out) or one stage of phase adjust. This allows a more extreme phase adjustment with a full swing of as much as 180 degrees or a less extreme 90 degrees of phase adjustment. Phase center lo/hi selects between a higher bandwidth phase adjust (button out)and a primarily lower frequency phase adjust (button in). This and the phase adjust button create the phase curve. It is important to note phase is frequency dependent and is different than time. For example depending on the two sources you are combining, and whether one source is direct and one is miked- between room reflections distance from the cabinet etc. determines what the curve would need to be. (e.g. you need to get the G note in phase as well the A note). Phase adjust knob determines the degree of phase adjust. On the rear of the unit you have a re-amp instrument level out. This will, when line level is selected bring the +4dB balanced signal down to instrument level. This output is affected by the phase adjust when selected. When instrument is selected the re-amp out is an instrument level output that is affected by the phase adjust(and can be used in a stomp box type mode). The level trim for the re-amp can be reached with a standard trim tool. Real time all analog phase sweep between zero and one hundred and eighty degrees... and everything inbetween. Allows mics to be placed where they sound best individually, compromising mic placement due to phase problems is not necessary when using the ibp. +4dB XLR balanced input and outputs. Internal super quality active transformer isolated line level direct box. Reamp capability for bringing +4dB line level signal to guitar level. Buffered instrument level output for driving long guitar cable. Allows splitting between two instrument amps with transformer isolation and phase sweep. Rack mountable 4 IBPs fit in a1U 19' standard rack space. Extremely high quality construction. Made in the U.S.A.

IBPJ - IBP Junior - Analog Phase Alignment ToolThis IBP Junior was designed to put the power of phase control in the palette of the creative audio engineers hand. Although most mixers and preamps have a phase-reverse switch, a simple 180-degree change in a signal's polarity may be more phase change than you need in a particular situation. The IBP Junior allows continuous control from 0 to 180 degrees over a mono signal. This allows to fine-tune the phase relationship between a miked guitar amp and a DI signal or a pair of drum mics. The result of such precise control can be as subtle as an increase in presence or as obvious as higher gain and an improved transient response.Features - Continuosly variable natural phase adjust. - Line level balanced XLR in and out. - Audiophile sound and construction. - Rack mountable, 4 units fit in a 1U space.

The PCP Instrument Distro signal splitter, router and DI is a master of many trades and could easily be an integral part of a personal studio that tracks live instruments. As a splitter it allows sending high-impedance signals to three separate destinations without a loss in audio quality or sound coloration. So one guitar signal can be sent to three amplifiers and recorded simultaneously. But it is not just for guitars, basses, and keyboards. The PCP can also be fed with line level signals - such as a previously recorded track - and routed to some vintage gear or stompboxes. With the integrated DI the low-impedance signal of the stompboxes can returned for rerecording. The PCP Instrument Distro can also be used as a line driver, helping to maintain the timbral quality of instruments over long cable distances and with the active DI output any instrument can interface pro-level gear. Each output has its own trim control, phase switch, and ground lift. Quarter-inch inputs and a matrix of controls are readily available on the front panel.Features - One to three-out guitar splitter - Three transformer isolated guitar level/ high-impedance outputs - Phase reverse, ground lift and level adjust on each output - Audiophile DI - Guitar line driver - Three line level inputs for re-amping
