Description:

The Interfacer is designed to manage all your input, tuning, muting, stereo summing, isolating, phase correction and output needs. 

There are two versions of The Interfacer.  The TX Interfacer (gold print) and The Interfacer (white print).  Both versions have the same features and are made with the same components except that The TX Interfacer adds an audio transformer to give the option of ground lift and phase correction (read more below). 

Summing
The Interfacer has two types of summing: Stereo Sum and Split Sum. To access these two modes, use the internal DIP switch to select which mode is best for you.

  1. Stereo Sum – This is the default mode The Interfacer ships with.  In this mode use stereo effects as normal. When summed, the left and right inputs are merged and the exact same signal is sent to the left and right outputs.
  2. Split sum – Still use stereo effects as normal. When summed, the right input is ignored and the left input is split to both left and right outputs.

Ground Lift & Phase Correction (The TX Interfacer only)

The Interfacer TX comes with ground lift and phase correction for players that want to run more than one amp.

  1. Ground Lift – There are times when two amps are being used that an audible hum/buzz can be heard coming out of your amps. When plugged into one amp only, the hum/buzz is not present.  This is commonly referred to as a ground loop.  This happens when there is more than one path to earth.  To safely fix this common problem, a transformer is needed to isolate your second amp and create one path to ground.  Push the red ground lift button to isolate your right amp from your left. 
  2. Phase Correction – Another common issue when running two amps is phase cancellation. Some amps are in phase in relation to each other and other amps are not.  When amps are out of phase with each other they are cancelling each other out.  This is most noticeable in the lower frequencies.  Normally this would mean you can’t use those amps together.  With the black phase correction button you can now put two amps that were out of phase, back in phase and working together.  To access this, turn on the transformer (red button) and flip the phase (black button).

Master Mute
Hit the foot switch on The Interfacer to mute your signal before it reaches your amps. No matter what craziness is happening on your board, the master mute has the final say on what does or doesn’t get sent to your amp.

Inputs

There are two inputs on The Interfacer; a moveable buffered input and a passive input.

  1. Passive Input – Best to use if you have effects on your board such as a vintage wah or fuzz that don’t quite sound the same with a buffer before them. After your last fuzz or wah pedal you can then plug into the buffered input of The Interfacer to make use of the buffer and dedicated tuner output. The passive input can also be used for off-board expression pedals and tap tempo.  Permanently connect either a TS or TRS cable from the passive send to a pedal that can receive expression or tap control and then patch an expression or tap pedal into the passive input.
  2. Moveable Buffered Input – The buffered input can be moved anywhere in your mono signal chain. Simply plug into the passive input, put all the pedals want you want before your buffer here. After the last pre-buffer pedal, plug into the buffered input to make use of the buffer and always on tuner output.

 

All Interfacers are made with high quality, durable components.

IMPORTANT – Use only 9vDC centre negative plug to power!  100mA
Dimensions including all jacks and switches are: 127mm long x 77mm wide x 73mm high.

    Great bang for your buck!
    Swapped out my old impeller and this helped fix my overheating issue. Super high quality, fit like a glove. If you know what you’re doing it’ll take you an hour tops. Super solid for the price! Fit into my 1990 alpha one gen 1 outdrive on my 4.3 Mercruiser.
