AES/EBU, S/PDIF Select for Input 1
Input 1 can be either balanced AES/EBU or unbalanced S/PDIF. The default setting for J7,
pins 1 & 2, is AES/EBU input via XLRs. Shifting the jumper to pins 2 & 3 enables the S/PDIF
input on phonos.
AES/EBU, S/PDIF Select for Input 2
Input 2 can be either balanced AES/EBU or unbalanced S/PDIF. The default setting for J8,
pins 1 & 2, is AES/EBU input via XLRs. Shifting the jumper to pins 2 & 3 enables the S/PDIF
input on phonos.
Presets
Two presets are available for adjustment of the input level trim, left and right, for the digital
inputs. Presets, P1 (left), P2 (right) provide 15dB of gain adjustment, to compensate for level
dierences in the digital input circuitry. These are preset on nal test and should not require
further adjustment.
Presets P15 & P16 are for altering the audio waveform symmetry (i.e. distortion). They are
factory set on nal test and should not be adjusted further.
A fth preset, P17, sets the VCA fader gain to 0dB when the fader is fully open. This is preset
on nal test and should not require further adjustment, unless it has been found necessary
to replace the fader or other VCA components.
General Purpose I/O
Two I/O pins are available on the remotes connector that can be congured for general
purpose use. They are completely congurable and can be set as inputs or outputs, latching
or momentary and active high or active low.
The setup procedure for conguring the pins is described in the following steps. Since the
settings are stored in non-volatile RAM, this only needs to be done once.

below) until the desired setting is selected. For example to set GPIO 1 to a latching,
active high input, press the PGM button until only the CUE/PFL button is illuminated
ON. This setting is then applied by pressing the ON button. The PGM button will ash
quickly for about a second to indicate that the setting is stored.
