Can I use analog bar graphs for digital inputs (or digital scales for analog inputs)?
Yes.
The range colors, break points and level references are set for the scale type and NOT
the source assigned.
For example assuming the following settings:
• Analog scale type: AES/EBU
• Analog/Digital scale reference: -18dBfs
• Analog 0dB reference: 0dBu
• Digital upper range point: -18dBfs
• Digital lower range point: -40dBfs
Feeding in analog 0dBu will produce a level of -18dBfs, with the color changes
occurring at -40dBfs and -18dBfs.
Changing the Analog 0dB reference to +4dBu will produce a level of -22dBfs, with the
color changes unaltered.
Changing the Analog/Digital reference to -20dBfs (with the analog ref still at +4dBu) will
produce a level of -24dBfs, with color changes unaltered.
The same applies to displaying digital channels on an analog scale; the color changes
will adhere to the analog upper and lower settings.
What are the RS232/RS422 options?
RS232 or RS422 operation can be selected via jumpers on the controller (CPU card),
as explained in the installation section.
Why are time clock/date settings lost when the frame is power cycled?
This data is normally maintained by a rechargeable battery situated on the CPU board,
which has a typical life of 6+ years. Loss of data indicates that the battery requires
replacement. Please contact your Snell dealer.
