Goodwood Audio Output TX Stereo and Mono Summing Junction Box

Output TX - Stereo to Mono Summing Manager w/ Ground Loop/Phase Correction

Output is designed for players that need a compact way to manage the outputs on their pedal board. Output takes care of multiple stereo to mono summing options while fitting underneath your angled board, or even under another pedal.

There are two versions of Output. Output TX (gold print, which is available here) and Output (white print). Both versions have the same features and are made with the same components except that Output TX adds an audio transformer to give the option of ground lift and phase correction.


Summing

There are two types of summing on Output: Stereo Sum and Split Sum. To access these two modes, use the internal DIP switch to select which mode is best for you.

Stereo Sum – The default mode Output ships with. 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.

Split sum – Still use stereo effects as normal. When summed, the right input of Output is ignored and the left input is split to both the left and right outputs.


Ground Lift & Phase Correction (Output TX only)

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

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.

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).
