Alto Aviation has introduced a new cabin audio amplifier, Alto Acapella DZ-290. The FAA-approved equipment was engineered as an upgrade solution for new or legacy systems. The system can be controlled through an Alto keypad, a legacy switch panel or optional software. It also features chimes control for NS and FSB ordinance connections. Alto says its installation requires minimal disruption to existing wiring.
The DZ-290 can interface directly with speaker level outputs from a PA-AV unit. It allows the audio to be passed directly to Alto speakers. The unit features an integrated four-channel amplifier with more than 160W of power to bypass the existing PA/IFE amp. It features internal four-source selection, volume and mute control. Selection may be made through ground logic or by optional software. PA override, chime inputs and default to PA make it possible to override existing PA-AV controllers.
The DZ-290 amplifier interfaces directly to the Audio International RS-485 databus for control of the Alto amp, enabling former Audio International equipment to remain in the aircraft.
