Crystal Vision
Statesman
Card-edge switches may be used to prevent silence detection from raising alarms via
these GPI outputs. Please refer to the Using card edge controls chapter for more
information.
Note:
The routing of ‘Loss of Reference Input’ warning to the GPI port cannot be disabled.
Adjusting the AES output phase
The time/phase relationship between the current reference input and the actual AES
output can be adjusted using the rotary AES o/p phase control.
Note:
The Set Phase function does not work unless a valid external reference is selected. If the
internal crystal oscillator is used, the phase control will be disabled.
To return the phase control to zero quickly, hold the mouse over the control, right click
and then select 'Calibrate'.
The phase angle setting is stored in non-volatile memory. Each reference input (AES,
Video or Word Clock) have their own memories for these values.
Every time the unit is powered up or the reference input selected or used is changed, the
new values are loaded into the ADCA output PCB to ensure optimum performance.
Audio monitoring
Audio monitoring is provided at the card edge with two miniature stereo jack sockets. The
left hand socket is connected to the Stereo 1 input signal and the right hand socket is
connected to the Stereo 2 input signal.
Setting channel gain and input termination
Please refer to the Hardware configuration section of the Installation chapter for channel
gain and input termination settings.
