TX-PA40DE

RDL TX-PA40D - 40W Stereo Audio Amplifier, 8Ω

The RDL TX-PA40D is a high-quality, compact Class D stereo amplifier designed for professional AV installations requiring reliable and efficient audio amplification. It delivers 20W RMS per channel into 8Ω (40W total) or 15W RMS per channel into 4Ω (30W total), supporting single or grouped speaker configurations.

TX-PA40D features unbalanced RCA line inputs (L/R), a stereo/mono mode switch, and front-panel gain trimmers for output level adjustment. Its built-in studio-grade analog compressor/limiter ensures clear audio and clipping control, maximizing average output power without compromising dynamics. A red LED indicates the compression threshold, while three dynamic time constants maintain transparent sound even with input overloads up to 20 dB.

The amplifier includes thermal and short-circuit protection, and its efficient Class D design minimizes heat generation. TX-PA40D is ideal for classrooms, boardrooms, video conferencing systems, and any application requiring fixed-gain amplification controlled by external equipment.
