MADI 700 Series Guide6
AM713/MA703 Front Panel
This section discusses both front panels and notes their few differences.
Signal Strength LEDs Each of the 28 channels has a four-seg-
ment LED that represents 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 be-
tween +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 currently locked. Sample rates are
auto-sensed but can be manually selected on the AM713. Sup-
ported 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 se-
lected. 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 indica-
tor 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 in-
ternal 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.
Manual Selection Buttons The button below each Sample Rate
LED row manually selects the sample rate. The AM713 also al-
lows manual selection of the Sample Rate Source.
Power Switch On/Off switch.

There are no user-serviceable parts in the
converters.
