The RDL RU-ADA4D is a professional-grade four-channel stereo audio distribution amplifier designed for precise audio routing in critical applications. Featuring both stereo (4 outputs) and mono (8 outputs) operation, the RU-ADA4D provides exceptional flexibility for professional audio installations.
Each of the two line-level inputs accepts either a balanced or unbalanced signal and is equipped with a front-panel input gain trimmer and dual-LED VU meter to ensure proper operating levels and ample headroom. A rear-panel switch allows easy selection between stereo and mono modes, enabling input A to drive all eight outputs in mono operation.
The amplifier delivers studio-quality audio performance with very low distortion, excellent crosstalk isolation, wide flat frequency response, extremely low noise, and high common-mode rejection. Inputs and outputs are provided on rear-panel detachable terminal blocks, and the unit operates from 24 VDC for versatile integration into professional systems.
