Troubleshooting
The Sonata AES-to-MADI converter has an integrated alarm system that
will alert the user of a power supply problem. There are three LEDs on the
front panel as well as an SMPTE standard alarm connector on the rear panel
for remote alarm monitoring. Internal regulated voltages are measured
along with the presence of each of the power supply voltages. Any internal
voltage error will turn the Alarm LED red.
LEDs
The Sonata converter power supplies are fully redundant and the unit can
operate using either supply. See
Table 20 for LED details.

Signal Present LEDs
The AES-to-MADI and MADI-to-AES signal present LEDs will be off
unless a valid AES signal is being decoded, at which time the LED will then
be green. The Analog-to-MADI and MADI-to-Analog will be green when a
signal is present between -50 dB and -4 dB full-scale. The LED's will turn
red between -4 dBFS and 0 dBFS.
