Eight presets are used to adjust the cleanfeed null for the left and right channels. Cleanfeed
is derived from the PGM or AUD output busses and are set up as follows. With the channel
routed to PGM only and a signal of 1kHz applied to the input and adjusted to register
0dB on the console output, P5 (left) and P6 (right) are adjusted for minimum signal at the
cleanfeed output connectors. The input signal frequency is then changed to 100Hz and P7
(left) and P8 (right) are adjusted for a level of –45dB at the cleanfeed output connectors.
Change the routing to AUD only and repeat the set up using presets P9, P10 at 1kHz and
P11, P12 at 100Hz. This will be set up during nal test and should not require further
adjustment, unless the channel position changes within the frame when minor adjustment
may be required to maintain best performance.
Two presets are available for adjustment of the Cleanfeed gain, left and right. The presets
P13 (left), P14 (right) should be adjusted to give 0dB output for the chosen source.
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 further 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.
