The HD-MA35U is a four input audio mixer amplifier for systems demanding the broadest range of features and the highest energy efficiency. Two output Power amplifier zones, 35 watts (Zone 1) and 4 watts (Zone 2), are driven from high-efficiency Class D amplifier stages. The mixer and amplifier sections all normally shut down (standby ''sleep'' mode) when audio is absent and automatically turn on when needed. The Zone 1 amplifier output level may be VCA controlled using various optional RDL remote controls, or by industry standard 0 to 10 Vdc or 0 to 10k ohm controls. This output drives 4 ohm or 8 ohm speakers. The output impedance is switch-selectable on the rear panel. The Zone 2 amplifier output drives an 8 ohm speaker and/or 600 ohm telephone equipment. The HD-MA35U is engineered, tested and manufactured in the U.S.A. to strict energy conservation standards. The unit consumes less than 1 watt of mains Power in standby mode, and meets Power amplifier efficiency specifications with analog-filtered Class-D digital output stages for both Power amplifier output zones and for the 600 ohm output.
