The MA1250 is the third generation of an amplifier with legendary reliability. 12 channel amplifiers have been built by Knolll Systems in Canada since 1996. The MA1250 heraldes a era in multi-channel, high-quality, affordable power amplifiers. The MA1250 is designed to meet the amplifier needs of custom installed multi-zone systems where high quality sound is a specific requirement. Extras such as the external voltage trigger that can turn the MA1250 on and off, gold input connectors, individual level or gain controls and channel link give the MA1250 exceptional value when installed in large complex systems. Except for the power switch all controls are rear mounted.
