RDL RU-PA40D Overview

The RU-PA40D 40W Stereo Audio Amplifier with USA Power Supply from RDL is an amplifier that is designed to power a pair of 4- or 8-Ohm speakers with adjustable gain. It can be used with projectors or with monitors with fixed audio outputs, in classrooms, boardrooms, or in video conferencing applications. In addition, it is ideal for foreground sound amplification in small to medium rooms or in a specific zone within a retail space.

The RU-PA40D is equipped with two balanced line-level inputs via a detachable terminal block and two unbalanced line-level inputs via gold-plated phono RCA jacks. Furthermore, a front-panel gain control trimmer sets the maximum gain for each channel. A front-panel switch to sum the audio inputs to mono is provided. A built-in stereo analog compressor/limiter is for audio fidelity and clipping suppression.

Finally, a blue power LED illuminates when the RU-PA40D is powered from its external 24 VDC power supply (included). The module is equipped with both thermal and output short-circuit protection.
