Introduction

Mini stereo power amplier

The AMP22 is a mini stereo power amplier with a power rating of 2 x 15 Watt, which lends itself perfectly to small speaker

systems requiring compact and economical audio solutions. It offers the ideal solution for applications such as classrooms,

ofces and meeting rooms where a small amount of speakers are required.

The compact size and very high efciency makes it perfectly suited to be hidden in a closet, on a false ceiling or mounted

under a desk or table.

The combination of the stereo balanced line and microphone input make it perfectly suited for applications where it should be

used in combination with projection screens and video sources while a microphone is connected. Two gain potentiometers

make it possible to control the sensitivity and balance between music and speech, while a switch allows bridging of the

output channels to obtain one channel with merged output power.

A remote wall panel can be connected for applications where local mixing of the inputs is desirable, while large distances can

be covered between the source and amplier using simple CAT5E twisted pair cabling. The volume controller input allows

connection of an additional wall controller for overall volume control.

The Class-D Amplier technology, standby mode and included switching power supply makes this device compliant to Energy

Star 3.0 and other strict energy efciency and environmental requirements.

Front panel

Chapter 2

Overview AMP22

The front panel of the AMP22 contains all the control and indicator functions.

Two gain control potentiometers are provided with which the gain of the line and microphone inputs can be

regulated separately and the balance between the music and speech can be set.

A slide switch provides the possibility to switch the amplier between Stereo and Mono / Bridge mode. If this

switch is set to stereo, the output will be stereo. If its set to Mono / Bridge, the Left and Right channels will

be summed to a dual-mono output.

Three indication LED’s for ‘ON / STANDBY’, ‘SIGNAL’ and ‘CLIP’ indicate the operation mode of the amplier.

The ‘ON / STANDBY’ LED will turn green when the device is switched ON and running. When no signal with

a sufciently high level is detected for a certain period of time, it will switch to standby mode and this LED will

turn orange. The ‘SIGNAL’ LED will turn green when a signal with a sufciently high level is detected and the

‘CLIP’ LED will start blinking when the signal reached the clipping level and the internal limiter starts working.
