AMIS120P 120W Power Amplifier

| Specifications | Architectural Specifications |

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.

AMIS1202P 120W + 120W Dual Channel Power Amplifier

| Specifications | Architectural Specifications |

Description
The AMIS1202P is a dual channel 120W + 120W power amplifier designed to deliver continuous full range performance in a compact and reliable package. The AMIS1202P is two independent amplifiers in the one chassis making it the perfect choice for multi-zone or multi-channel applications.
Inputs and Outputs
The AMIS1202P provides dual balanced XLR inputs (male and female) per channel. These two inputs are wired in parallel enabling a line level 'split' to be taken from the second input of each channel. 70 volt line and 4/8 ohm outputs are available via the rear panel barrier strip.
Controls and Metering
A recessed input attenuation control for each channel is included on the rear panel. These pots are accessible using a screwdriver. The AMIS1202P features a signal-present LED per channel and power-on LED.
