FP-PA35A

RDL FP-PA35A - 35W Mono Amplifier for 25V / 70V / 100V Systems with Compressor and Sleep Mode

The RDL FP-PA35A is a professional Class D mono amplifier delivering 35W RMS, designed for constant voltage audio systems operating at 25V, 70V or 100V. With compact design, high audio fidelity, integrated compressor, and automatic sleep mode, the FP-PA35A is ideal for commercial, educational, and paging AV installations.

It features a balanced or unbalanced line-level input, front panel gain control, and selectable constant voltage outputs for powering multiple speakers in a zone. The analog compressor uses three dynamic time constants to control clipping while preserving audio transparency and dynamics.

The FP-PA35A includes an energy-saving sleep mode that reduces power consumption to under 1 W when no audio signal is present. The delay can be set to 5, 15 or 25 minutes, or disabled. The amplifier resumes full operation within 150 milliseconds upon signal detection.

Its all-metal housing, UL 2043 plenum rating, and built-in thermal and short-circuit protection ensure safe and reliable performance in demanding environments.
