AEQ AM-04

Analog, AES/EBU and SDI embedded Audio Monitor with Alarm System

Alarms are only generated in respect of selected audio signals when the ALARM SET switch
is in the SET position.

Why can’t I enable an audio tone or external alarm for anti-phase errors?

Only the phase LED on the front panel is armed using the SET switch. The audio tone and
external phase alarms must be armed using serial control. Anti-phase errors are a common
feature of most audio sources and may not require a high-priority alarm.

De-muxed audio is corrupted or muted in SDI mode

Check the position of the PAL/NTSC switch at the rear of the unit.

Note:

In the unlikely event that the unit locks up, switch the unit off at the rear for a few

seconds and then restore power.
