35W power amplifiers
These ultra high efficiency amplifiers are the first full-featured environmentally conscious "green" mixer amplifiers for commercial installations. These products include studio quality microphone input stages, line-level transformer isolation, equalization, remote control capability and integral analog compression coupled to sonically pleasing analog-filtered high efficiency Class D output stages. An internal low-power-consumption processor monitors usage demands to completely shut down internal circuitry for maximum power conservation and extremely low long-term operating cost. There are three units with 4ohm/8ohm outputs and three units with 25V/70V/100V outputs (labeled with an "A" suffix), for a total of six models. The HD prefix stands for Half Dual (half rack width, dual RU height).
