10.8 6050-0008 EvacU Standalone Isolation 50W Amplifier
(NOTE: ONLY FOR USE ON EV3000 AND EV100 AMPLIFIERS)
Where there is a requirement that an isolated amplifier is required the Standalone Isolation amplifier can
accommodate most instances. This unit connects to an EV3000 100V amplifier line circuit and
reproduces the signal produced using a battery backed 50w amplifier mounted inside the remote
cabinet.
It can be used for secure line applications or to add additional capacity to an already loaded circuit.
The internal 100V output line is monitored for shorts and interruptions. Any fault present within the
standalone system will be transferred to the 100V source input line via a switching resistor.
A local background music input is provided on the isolation amplifier for individual tenancy applications.
This allows the installer to have background music playing on the remote isolation amplifier zone. In the
event of the source 100V line being triggered the background music will be switched out for the priority
of the source 100V line. (NOTE: Line monitoring for 120W amplifiers is only compatible with
amplifiers manufactured post 2016)
Output volume and VOX Input sensitivity can be adjusted via the pots on the 100V to line level convertor.
