Product Spotlight

RDL’s RU-PA40D 40 W Stereo Audio Amplifier with VCA is ideal choice for many applications where a versatile, high?quality utility amplifier is needed to drive a pair of 4 Ω or 8 Ω speakers and provide remote level control.?

This unit features a front panel switch for Stereo or Summed Mono operation.? In Summed Mono, both input signals are summed and equally distributed to both outputs – great for two zone operation.? Whether in stereo or mono mode, this amplifier is perfect for classrooms, boardrooms, lobbies, hotels, restaurants, retail facilities, and so much more.? ?

Here are several more features that add to its versatility.? It has two balanced line level inputs to accommodate professional sources and Dual RCA Jacks to support consumer sources. ?There are two gain control trimmers on the front panel that allow independent gain levels for each channel.?

This amplifier is equipped with a stereo VCA (Voltage Controlled Amplifier) for setting the output levels on both channels. VCA’s adjust signal levels in Solid State circuitry, which means no moving parts to wear out.? This design provides users with long-term pop and noise-free level adjustment. RDL provides many remote controls to choose from including single-turn, multi-turn (rotary encoder) or pushbutton (ramp or fixed level selection) controls.

There’s a built-in stereo analogue compressor/limiter which provides much greater audio fidelity than Class D amplifiers with only digital limiting.? This compressor is designed to restrict loud audio signals and peaks from clipping the amplified output, while passing normal audio signal levels through unaffected and preserving audio dynamics.? The input GAIN settings determine whether the limiter alone is used for clipping suppression, or if the full compressor/limiter will be used to substantially increase the average output power beyond that of a standard 40 W amplifier.

Wherever a compact, high-quality, stereo audio power amplifier is needed to provide reliability and unsurpassed versatility, the RU-PA40D is the ideal choice.
