HD-PA35A

RDL HD-PA35A - 35W Mono Amplifier with Tone Control, Compressor and VCA Control, Constant Voltage Output

The RDL HD-PA35A is a professional Class D mono amplifier delivering 35W RMS with constant voltage outputs (25V, 70V or 100V), designed for zone-based AV, paging and commercial systems. It features a single audio input with front-panel volume control, bass and treble tone adjustment, integrated compressor, and remote VCA level control.

Speaker output is provided via detachable terminal block, allowing connection of multiple speakers in a zone. The HD-PA35A can operate as a standalone zone amplifier or as an extension to RDL HD series mixer amplifiers.

Its analog compressor uses three dynamic time constants to control clipping while preserving audio transparency and increasing average output power. A front-panel LED indicates compression activity, and standby mode can be manually or automatically activated.

With metal housing, included 24V DC power supply, and built-in thermal and short-circuit protection, the HD-PA35A ensures reliable performance in demanding AV environments.
