This section discusses both front panels and notes their few differences.

Figure 2-1AM713 Front Panel

Signal Strength LEDs: Each of the 28 channels has a four-segment LED that repre-

sents the following signal levels: -42 dB, -18 dB, -6 dB (green), -0.05 dB (red).

Trim Pots Access: Three trim pots adjust the maximum analog input level of channels 1–8, 9–16, and 17–24 in 2-dB steps between +12 and +26 dBu.

SR Conv: This indicates sample-rate conversion activity on the auxiliary digital inputs.

Sample Rate LEDs: These LEDs indicate the sample rate to which the converter is cur- rently locked. Sample rates are auto-sensed but can be manually selected on the AM713. Supported sample rates are 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz, and Custom rates from external sources.

Sample Rate Source LEDs: These LEDs indicate the format of the Sample Rate Source to which the converter is currently locked. Sample Rate Source can be auto- sensed or manually selected. If an external source is not detected, the AM713 reverts to Internal sync; the MA703 mutes its outputs. If a manually selected source is not present, the Sample Rate Source indicator blinks.

•AES: Sample Rate locked to AES Input.

•Word: Sample Rate locked to Word Clock Input.

•Internal (AM713 only): Sample Rate locked to its own internal crystal.

•MADI (MA703 only): Sample Rate locked to MADI.

•Auto: Sample Rate Source has been auto-sensed.

These LEDs appear in the same order in which signals are tested for their presence. This detection procedure occurs when the converters are powered on. The Sample Rate (AM713 only) and Sample Rate Source can also be selected manually.
