Power Switch and “On” LED
The black rocker switch on the right hand side of the front panel is used to switch the amplifier on and off.
The ‘up’ position is on. When the amplifier is connected to an appropriate AC power source and is
switched on, the blue LED will illuminate. This LED will always be on when operating on 24VDC.
Signal LED
The green “Signal” LED located next to the ’On’ LED indicates that the AMIS120XL is passing audio. The
signal LED is a simple method to trouble-shoot installations especially in multi-amplifier projects.
Rack Mounting
The AMIS120XL is supplied with rack ears attached to allow mounting within a standard 19” equipment
rack. As is the case with almost all audio products, adequate ventilation and air flow is required. When
installing multiple AMIS amplifiers within the one rack, it is recommended that at least 1 rack unit of
ventilation space is left between every two amplifiers.
For table or shelf mounting, the rack ears can be removed using a screwdriver. Once the rack ears are
removed, please reinstall the screws.
Rear Panel Features
AC Power Inlet
The 3 pin IEC power inlet is located at the bottom left of the rear panel and accepts a standard mains power
lead fitted with an IEC connector. The operating voltage is 115volt @60 Hz and the inlet is equipped with
an in-built AC fuse holder fitted with a 8 Amp slow blow fuse plus a spare fuse. Power consumption is 250
watts (max).
---Please ensure that the mains power cord is disconnected before attempting to check or replace this
fuse.---
24 Volt DC Power Inlet
The AMIS120XL features optional 24VDC power to run off a battery supply if required. This is connected
via the rear terminal strip. The front panel Power Switch will not switch DC power ‘on’ or ‘off’ in DC
operation. In this mode the amplifier is always ‘on’.
