ZRM4
Featuring 6 inputs that can be balanced XLR mic or dual RCA/balanced XLR line level, all available to any combination of 4 zone outputs.
Input one can be designated as a paging input with priority over all other inputs individualy selectable at each zone output. Front panel switches with LED indication provide
for simple routing of each input. Each input has bi colour status LED indication & 2 stage equalization. Each input has an internal gain trim which can provide a further +/-
15dB of gain to allow the perfect set up of input gain no matter what the input signal may be. Phantom power & high pass filters are also supplied per input.
Each balanced XLR zone output also features a dual colour status LED & switchable paging mic priority. Remote VCA’s are also available for each output
allowing for a wall mounted volume control to be installed in remote zones giving a volume range from off to whatever the master level on the
AMIS ZRM4 relevant zone output is set to.
Alert, Evacuation, Bell & Pre announce tones are also provided on board.
The AMIS ZRM4 is a compact yet extremely versatile zone routing
mixer which makes the complex task of multizone
signal routing simple & cost effective.
