RDL RU-ADA4D Audio Distribution Amplifier
EAN: 813721013408
The RU-ADA4D from RDL is a four-channel stereo audio distribution amplifier with input and output gain adjustments and input-level metering. The module may be operated in mono to provide up to eight distributed mono signals. The inputs and outputs are connected on rear-panel detachable terminal blocks.
Each of the two line-level inputs accepts either balanced or unbalanced signals. Each input is equipped with a front-panel trim level. Levels between -14 dBV unbalanced and +9 dBu balanced may be set to the proper operating level as indicated by a dual-LED VU meter. This assures ample headroom at all normal operating levels. The maximum input level is + 25 dBu.
Arear-panel switch selects between stereo and mono operation. In the mono position, input Ais used to drive all 8 output channels. When the module is used in a monaural system, only input Amust be wired.
Audio outputs are isolated from each other and may be wired balanced or unbalanced. Each of the outputs is provided with a front-panel screwdriver adjusted Output Level control. Relative to a balanced +4 dBu output level, this gain potentiometer allows an adjustment range from -9 to +6 dB. Relative to an unbalanced -10 dBV output, each output potentiometer allows an adjustment from -3 to +12 dB.
The RU-ADA4D offers generous headroom, low distortion, crosstalk isolation, wide frequency response and low noise with high common-mode signal rejection. It provides quality performance for professional audio applications.
