RDL RU-ADA4D - Stereo/Mono Audio Distribution Amplifier with Level Control

The RDL RU-ADA4D is a high-performance audio distribution amplifier designed for professional AV applications. It distributes stereo audio to four outputs or mono audio to eight outputs, with input and output level adjustment and visual level monitoring via dual-LED VU meters.

Inputs and outputs are connected via rear-panel detachable terminal blocks. Each of the two line-level inputs accepts balanced or unbalanced signals, with input gain adjustable via front-panel trimmers. A rear-panel switch selects stereo or mono operation. In mono mode, input A (left) drives all eight outputs.

RU-ADA4D delivers exceptional audio quality with high headroom, low distortion, excellent channel isolation, and ultra-low noise. It operates on 24 V DC power.
