Product description The RDL HD-MA35 35-Watt Remote Mixer Amplifier is a versatile audio amplifier, mixer and paging system targeted for background music, call on-hold music, and commercial audio applications. The amplifier features two zones with Zone 1 delivering 35 watts and support for balanced and unbalanced inputs, and audio output to 4- and 8-ohm speakers. Zone 2 is reserved for an 8-ohm speaker or 600-ohm telephone equipment, and capable of 4 watts.The unit is built to high energy efficiency standards with automatic power up when signal is present, and a threshold adjustable "sleep mode" that powers down the amplifier when there is no audio signal. The HD-MA35 prioritizes paging audio with adjustable muting and ducking functions that lower or interrupt background music during pages. The amplifier is more than ideally suited for commercial retail, offices, warehouses, restaurants, bars, and various other environments that require a versatile and efficient audio paging amplifier. - Three inputs with individual front-panel volume controls
- Bass and Treble tone controls
- Designed for background music with paging and music-on-hold
- Master volume VCA controlled with remote adjustment capability
- Manual or automatic (VOX) priority ducking
- Balanced inputs and amplified outputs on detachable terminal blocks
- Unbalanced inputs and outputs on RCA jacks
- High-efficiency Class D operation
