RDL HD-PA35 - 35W Mono Amplifier with Tone Control, Compressor and VCA Control

The RDL HD-PA35 is a professional Class D mono amplifier delivering 35W RMS into 4Ω or 8Ω, designed for low-impedance AV, paging and zone 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, with impedance selectable on the rear panel. The HD-PA35 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-PA35 ensures reliable performance in demanding AV environments.
