House/building amplifier HA203R65 is the first amplifier within our offer which is equipped with output stage using Gal-As semiconductor components, working in push-pull mode. The next innovation is driving stage, employing IC made of Si-Ge semiconductor. Such a solution significantly reduces non-linear distortions, especially of second order.
The amplifier has been equipped with attenuator, correction of cable characteristics, and test output (-30 dB). It has passive back channel and uses F-type connectors.
Main features
- - push-pull output stage made of Gal-As semiconductor components
- - built-in attenuator and cable attenuation equalizer
- - built-in test output (-30 dB)
- - F-type connectors
