AMIS250P

250W Power Amplifier

Description

The AMIS250P is a 250 watt power amplifier with outputs for 4 ohms, 70 and 100 volt line. It

may be desk or rack mounted. The AMIS250P features a flat screwdriver accessible gain con-

trol on the rear panel. The amplifier may operate from mains power or 24V DC.

Inputs

The AMIS250P features two signal inputs. Two line level sockets are provided for bridged

in/out connection.

Outputs

The AMIS250P features 100 volt, 70 volt and 4 ohm isolated transformer outputs.

Protection

Internal current limiting protects the amplifier from both overload and overdrive conditions.

The AMIS250P also features protection in the form of excess temperature auto cut out. An in

built auto temperature sensing fan will turn on at a factory default level but in most situations,

will never be required.

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 250 watt power amplifier shall be designed to run 100 volt line audio systems. The unit shall also

features a four ohm output. The amplifier may be desk or rack mounted.

The unit shall feature high temperature protection with front panel indication. An in built auto temper-

ature sensing fan shall cool the unit when required and automatically turn off again once the amplifier

is running at the correct temperature. The amplifier must be capable of delivering 250 watts into a forty

ohm inductive load with less than 0.5% distortion measured at 1kHz and with system hum and noise

less than -74dB.

The amplifier shall be an Australian Monitor Installation Series model AMIS250P.
