Extron electronic 12800 manual Setting the default audio gain

Setting the default audio gain

By default, the audio gain of each output is set to 0 dB (unbalanced) and

6 dB (balanced). You can reduce this setting by 6 dB (-6 dB [unbalanced],

0 dB [balanced]). Change the audio gain for one or more outputs as follows:

CDo not touch the electronic components or the connectors on the backplane or on the circuit cards without being electrically grounded. Handle circuit cards by their edges only. ESD can damage ICs, even if you cannot feel, see, or hear it.

NRemove two cards for a stereo output and one card of a mono output.

1. Use the table below and figure 6-15 on page 6-17 to identify the cards for the output to be set.

Output		Output cards (stereo)	Output card (mono)
1 - 16		Left 1, Right 1	Left 1
16	- 32	Left 2, Right 2	Left 2
33	- 48	Left 3, Right 3	Lef 3t

CDo not touch the electronic components or the connectors on the backplane or on the circuit cards without being electrically grounded. Handle circuit cards by their edges only. ESD can damage ICs, even if you cannot feel, see, or hear it.

NThe audio output cards are the longer cards in the bottom row, inside the I/O cardcage door of an audio BME.

2. Remove the audio output cards from the card. See “Removing the I/O card“, on the previous page. Place the removed card on an anti-static surface with the jumpers facing up.
