Front Panel Features
Power Switch
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 power LED will illuminate. This switch will not switch DC power on or off in DC
operation. In DC operation mode, the amplifier is always on and the blue power LED will always be
illuminated.
‘On’ LED
The blue “On” LED above the power switch will illuminate when the amplifier is connected to mains
power and is switched on, or when the amplifier is connected to DC power.
Signal LED
The green “Signal” LED located next to the ‘On’ LED indicates that the AMIS120P is receiving audio
signal via its line level input. The signal LED is a simple way to trouble-shoot installations especially in
multi amplifier projects. At a glance the signal LED will indicate that audio is reaching the amplifier.
Rack Mounting
The AMIS120P 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 AMIS120P power amplifiers within the one rack, it is recommended that at least one
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 operating voltage is 230/240 VAC @ 50 Hz. The 3 pin IEC power inlet is located on the bottom left of
the rear panel and accepts a standard mains power lead fitted with an IEC connector. Before plugging in a
power lead, please check the rear panel of the amplifier to ensure that the voltage switch is set correctly for
your part of the world.
