RDL RU-ADA8D Audio Distribution Amplifier, Balanced/Unbalanced - 2x8, 1x16

Because of its robust and versatile design, the RU-ADA8D Audio Distribution Amplifier stands as a powerful tool for professional audio environments. This high-quality amplifier boasts eight channels of stereo audio distribution, complete with input and output gain adjustments and input level metering. It's capable of operating in mono mode, providing up to sixteen distributed mono signals for maximum flexibility.

The RU-ADA8D is equipped with rear-panel detachable terminal blocks for both inputs and outputs. Each of the two line level inputs can accommodate either a balanced or an unbalanced signal, making it a reliable choice for various audio setups. For precise control, each input features a front panel INPUT GAIN trimmer, allowing for signal levels between -14 dBV unbalanced and +9 dBu balanced to be set to the optimal operating level. A dual-LED VU meter ensures accurate level setting, providing ample headroom at all normal operating levels. The maximum input level of +25 dBu further enhances its versatility.

A rear-panel switch allows for easy selection between stereo and mono operation. In mono mode, input A (left) drives all 16 output channels, simplifying the wiring process in a monaural system. The audio outputs are isolated from each other and can be wired either balanced or unbalanced, offering a durable solution for complex audio distribution needs.

Each output is equipped with a front panel screwdriver-adjusted OUTPUT LEVEL control. This allows an adjustment range from -9 dB to +6 dB relative to a balanced +4 dBu output level, and an adjustment from -3 dB to +12 dB relative to an unbalanced -10 dBV output.

The RU-ADA8D Audio Distribution Amplifier is known for its exceptional headroom, very low distortion, excellent crosstalk isolation, and wide flat frequency response. It operates with extremely low noise and offers very high common-mode signal rejection, ensuring high-quality audio performance for the most critical applications. The RU-ADA8D operates from a 24 Vdc connected through a rear-panel detachable terminal block, solidifying its place as a reliable and powerful audio distribution solution.
