Product description The HD-MA35U 35-Watt Mixer Amplifier from RDL features dual-zoned amplifier outputs and is designed for use in applications requiring background music with paging or music on hold functionality. The unit has 4 audio inputs each with independent volume controls, including 2 mic- or line-level inputs on terminal blocks and 2 stereo RCA line inputs that are each summed to mono.
The HD-MA35U features 2 mixers. Its Zone 1 mixer provides 35 watts of amplifier output for background music use, while the Zone 2 mixer has 4 watts of output on a 600 Ohm connection for music on hold scenarios. Additionally, a line-level output allows for connectivity to a separate power amplifier. - Four 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
- Automatic sleep mode for energy savings
