Product description The HD-MA35UA 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-MA35UA has two output power amplifier zones, 35 watts (Zone 1) and 4 watts (Zone 2), and are driven from high-efficiency Class D amplifier stages. The mixer and amplifier sections all normally shut down (standby "sleep" model) when audio is absent, and automatically turn on when needed.
The HD-MA35UA 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 and/or background music in a small zone equipped with an 8 ohm speaker. Additionally, a line-level output allows for connectivity to a separate power amplifier. This unit comes with a USA power supply. - 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
- Analog compressor/limiter for Zone 1
