APart MA60 [8/28] Mixing amplifiers

Mixing ampliﬁers

1. Emergency input: connect your balanced 0 dBV line level

emergency input on the euroblock connector. If available,

connect the emergency contact at the “mute all” connection.

The contact must be “potential free”, i.e. a relay or switch

contact that does not carry any foreign voltage. The emergency

level can be set with the volume control only. If the clip led

lights up when the emergency signal is present, lower the

level of the emergency signal at the source to avoid distortion.

Activating the emergency input will also activate the priority

output (6).

2. Paging mic input: connect your paging mic here: the input

accepts microphone level signals on balanced euroblock and

line level signals on RCA. Adjust the gain potmeter so that

the clip led does not light up when the signal is at its highest

level. Then set the volume control as desired. When the paging

contact is closed, all other sources (except emergency input)
