CMT 300.2

2ch 300W High-Z (70/100V line) amplifier

The CMT series feature compact, light and powerful high voltage Class-D amplifiers with built-in Line Matching Transformers to power high impedance (70/100V) speakers. Each channel has a balanced input and output with separate volume controls.

Features

  • 2 inputs and output channels 

  • Switching power Class-D circuitry 

  • 70 / 100V selector switch 

  • All amplifiers feature warning information and commands, like Failure Status, Amplifier Disable, Prior and Rest Alarm for easy reporting and servicing.
