Mute with Standard Contact Closure
The amplifier is designed to mute all outputs (including AUX OUT) when a trigger is detected via
the MUTE connector. This is triggered from a standard contact closure. Use the included 2-pin
Euroblock.
Setup – Rear Panel Controls
Amplifier mode DIP switches
Page/Mic Normal – Bypass Master
Determines if page input source will follow the master level output or can be set at an indepen-
dent output level to ensure announcements are heard.
Output Mono - Output Stereo
Determines if stereo input sources will be output in mono or stereo via loudspeaker connectors
and Aux Out RCA connectors.
Note: On the IZA 250-LZ amplifier, Output 1 is the left channel and Output 2 is the right channel
when set to Output STEREO. On the IZA 190-HZ, the left channel is routed to the loudspeaker
output when set to OUTPUT STEREO.

output level will be automatically lowered (“ducked”) when someone speaks into microphone.
