• Repeat this procedure for each of the four output connectors of each of the
three Analog Output Units.
Notes: Please consider that maximum undistorted level of the analog outputs is
+23 dBu (@ 0 dB
not exceed a value of +14 dBu (with an input signal of –9 dB
ering the standard headroom margin of 9 dB.
Once finished, don't forget to re-establish the console settings as they
were before the alignment procedure.
• Select the Channel Control page (e.g. "I 9A"): Touch HOME and press the
SEL key of the corresponding channel. Perform the following settings on
the Channel Control page:
MODE: ST (stereo), LR (normal stereo mode)
PHASE: NORM
CAL: 0 dB
Routing: to the PGM and REC outputs; the ΣPROGRAM and ΣRECORD
touch-screen fields must be highlighted.
BAL: center position.
• Switch the equalizer off by pressing the EQ key if it is illuminated.
• Switch the console off.
• Open the console according to
nected so that the console remains operative.
• Remove the Analog Output Unit to be aligned (refer to
re-connect it to connector P71 of the DSP board using the 64pin extension
cable 1.942.500.26. Reconnect the daisy-chain flat cable of the Output
Module Bus to the extension cable. Now the Analog Output Unit can be
placed in front of the console on an insulating sheet, e.g. a piece of card-
board. Put down the console front cover, but don't fix it with its screws.
• Set the jumpers of the Analog Output Unit temporarily to RECORD (for
the lower/"B" output connectors) and to PGM (for the upper/"A" output
connectors), select STEREO for both outputs A and B; refer to the illus-
tration on the following page.
• Switch the console on again.
• Switch the corresponding channel ON, and set its channel fader as well as
the PGM and REC faders to their 0 dB position.
• Connect an analog audio level meter to one of the PCB's output connec-
tors.
• Align for a reading of your desired nominal level (default factory setting:
+6 dBu) on the audio level meter; select the corresponding trimmer poten-
tiometer according to the table below.
