Optimod-Surround 8685 V1.0 Operating Manual - Orban

OPTIMOD SURROUND PROCESSOR INSTALLATION 2-27
If the AGC gain reduction meter averages more gain reduction (lower on
the meter), re-adjust the SURROUND INPUT REFERENCE (VU or PPM) to a
higher level.
H) When finished, reset the 8685’s SURROUND EXTERNAL AGC control to YES, if required
(e.g., if that was its setting prior to your setting the SURROUND INPUT
REFERENCE (VU or PPM) level).
Refer to step 2 on page 2-20.
8. Adjust the 2.0 input reference Level.
[Skip this step if you will not be using the 2.0 processing.]
Repeat step 7 on page 2-25, but use the 2.0 INPUT REFERENCE (VU OR PPM) control.
If you choose to calibrate using tone or program material, drive the 2.0
processing’s inputs. All four 2.0 processors share the same reference level.
9. Set the 2.0 output configuration.
[Skip this step if you will not be using the 2.0 processing.]
All four 2.0 processors share the same configuration and cannot be configured
independently.
A) LOCATE to INPUT/OUTPUT > 2.0 OUTPUT (INPUT/OUTPUT 3).
B) Set the 2.0 OUTPUT SYNC to INTERNAL, IN 1-2, SYNC IN, VIDEO SYNC, SDI or any of
the 8685’s AES3id inputs.
• INTERNAL synchronizes output sample rate of the 2.0-connected hardware
output that carries the 2.0 processing to the 8685 internal crystal time base.
If there is no valid signal present on the chosen reference input, the 8685
uses internal sync until a valid signal appears.
• SYNC IN synchronizes the output sample rate to AES3id, AES11id, or word
clock applied to the 8685’s SYNC INPUT. It will overwrite the setting of the
8685’s 2.0 OUTPUT RATE control.
• IN 1-2 synchronizes the output sample rate to a signal appearing on AES3id
input 1-2.
• VIDEO SYNC synchronizes the sample rate to a SMPTE 274M or SMPTE 296Mcompliant
source applied to the 8685’s VIDEO SYNC INPUT. It will overwrite
the setting of the 8685’s 2.0 OUTPUT RATE control. This source is available
only if the optional HD-SDI module is installed.
• SDI synchronizes the sample rate to a SMPTE 259M, 292M, or 424Mcompiant
signal applied to the 8685’s HD-SDI input. This source is available
only if the optional HD-SDI module is installed.
When using Penteo in its loop-though mode when using HD-SDI input
and output (i.e. using the optional HD-SDI module’s AES3id inputs and
outputs to connect to the Penteo), it is unnecessary to lock the sample
rates appearing on the AES3id outputs to house sync because the AES3id
