MICROPHONE PRIORITY
When the paging microphone is switched on the music volume is lowered
temporarily to approximately 10% of the set level. This enables
announcements to be made over the music. Once the microphone is released
the original music volume is restored.
MUSIC OUTPUTS
The music output for each zone is via Weidmuller terminal connectors.
Connections to the connectors are via the mating halves supplied with the
unit. These are screw connections and the two halves of the connector can
be screwed together to prevent the connections coming apart.
Each output is balanced and can drive loads as low as 600
Ω
. For balanced
operation we recommend using a 2 core screened audio cable. Connections
