AMIS 120P

120W Power Amplifier

Description

The AMIS120P is a 120 watt power amplifier with outputs for 4 and 8 ohms and 70 volt line. It may
be desk or rack mounted. The AMIS120P features a flat screwdriver accessible gain control on the
rear panel. This amplifier features a status LED.

Inputs and Outputs

The AMIS120P features a balanced line level XLR input with a parallel output to feed additional
power amplifiers. The unit has industry standard 3 pin XLR microphone sockets. The AMIS120P fea­tures 70 volt, 8 and 4 ohm isolated transformer outputs via a rear panel barrier strip.

Protection

Internal current limiting protects the amplifier from both overload and overdrive conditions. Should
the amplifier be overdriven, a current limiter will protect the unit, and in a worst case scenario the
amplifier will shut down until the problem is resolved. Once the problem is fixed (shorted speaker
line, or overdriven input), the amplifier will automatically reset and continue operation. The
AMIS120P features generous heatsinking.
Australian Monitor Installation Series amplifiers feature a protection network that provides greater
stability and performance. Our amplifiers are recognised worldwide for their
reliability and this is due to the extensive levels of current limiting which pro­tect the amplifiers from both overload and overdrive conditions.

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS

The 120 watt power amplifier shall be designed to run 70 volt line audio systems. The unit shall also feature
a 4 and 8 ohm output. The amplifier may be desk or rack mounted.

The amplifier must be capable of delivering 120 watts into an 40 ohm inductive load with less than 0.5% dis­tortion measured at 1kHz and with system hum and noise of -80dB or better. Internal current limiting shall
protect the amplifier from both overload and overdrive conditions.

The amplifier shall be an Australian Monitor Installation Series model AMIS120P.
