AMIS604P, 4 x 60 Watt Power Amplifier

Product Description

The AMIS604P is a four channel (4 x 60w) power amplifier designed for commercial installations. The one
unit contains four independent 60 watt amplifiers for multi-zone applications. The AMIS604P can be used
for either low impedance (8 ohm) or 70v/100v line speaker systems per channel. The amplifier can be
mounted in a standard 19” equipment rack (rack ears supplied) or it can be used on a shelf or table. The
AMIS604P features a line level input (with parallel output) per channel and is normally used with mixers,
mixer amplifiers or other power amplifiers.

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. When 24vdc power is connected the LED will always be on.

Signal LED

The green “Signal” LED’s located next to the “On” LED indicate that the AMIS604P is receiving audio
signal via its line level inputs. One LED is provided per channel. The signal LED’s are a simple way of
trouble-shooting installations especially in multi amplifier projects. At a glance the signal LED’s will
indicate that audio is reaching the amplifier.

Rack Mounting

The AMIS604P 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 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
