Introduction

Mini Stereo Power Amplifier

The AMP20

MK2

is a Mini Stereo Power Amplifier 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, offices

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

The compact size and very high efficiency 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 mixer can be connected for applications where local mixing of the inputs

is desirable, while large distances can be covered between the source and amplifier

using simple CAT5 twisted pair cabling. The volume controller input allows connection

of an additional wall controller for overall volume control.

The Class-D Amplifier technology, standby mode and included switching power supply

makes this device compliant to Energy Star 3.0 and other strict energy efficiency and

environmental requirements.
