The HD-PA35UA is a single input audio amplifier for systems demanding the highest energy efficiency. It may be used as a single zone amplifier fed from a variety of RDL or OEM mixers. It is ideal for providing one or more additional zones to a mix originating from another RDL HD series mixer amplifier. The 35 watt power amplifier output is driven from a high-efficiency Class D amplifier stage. The amplifier normally shuts down (standby “sleep” mode) when audio is absent and automatically turns on when needed. The 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. The amplifier provides a constant voltage output (25 V, 70 V or 100 V).
The HD-PA35UA 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 an analog-filtered Class-D digital output stage.
The HD-PA35UA provides a front-panel control to set the input gain. An optional remote control connected to the rear-panel RJ45 jack provides for remote adjustment of the output level. The tone controls adjust the equalization at the amplifier output.
