What sets the RU-ADA4D Audio Distribution Amplifier apart is its versatile functionality and professional-grade audio fidelity. This robust four-channel stereo audio distribution amplifier is designed to seamlessly integrate into both balanced and unbalanced audio setups, making it an ideal choice for a variety of professional audio environments.The RU-ADA4D is equipped with precision input and output gain adjustments, allowing for meticulous control over audio levels. This feature, coupled with the unit's input level metering, ensures that signals are optimally set for the clearest audio output. The dual-LED VU meter provides immediate visual feedback, facilitating the accurate setting of input signal levels ranging from -14 dBV unbalanced to +9 dBu balanced, with a maximum input capability of +25 dBu. This level of control guarantees that the RU-ADA4D maintains ample headroom, avoiding distortion at all normal operating levels.Flexibility is a key attribute of the RU-ADA4D, as it can be configured for mono operation to distribute up to eight mono signals from a single input. This is achieved through a simple rear-panel switch that toggles between stereo and mono settings. In mono mode, input A (left channel) becomes the source for all eight outputs, simplifying the wiring process for monaural systems.Connectivity is straightforward and secure, with rear-panel detachable terminal blocks providing a reliable connection for both inputs and outputs. Each line-level input is designed to accept either a balanced or an unbalanced signal, and is furnished with a front panel INPUT GAIN trimmer for precise level adjustments.The RU-ADA4D stands out for its exceptional audio performance characteristics, including very low distortion, excellent crosstalk isolation, and a wide, flat frequency response. Its extremely low noise floor and high common-mode signal rejection rate ensure that the audio signal remains pristine and uncolored, which is paramount for critical listening and recording scenarios.Engineered for continuous operation, the RU-ADA4D is powered by a 24 Vdc supply connected through a rear-panel detachable terminal block, ensuring stable and uninterrupted service. Whether used in broadcast studios, live sound reinforcement, or other professional audio applications, the RU-ADA4D Audio Distribution Amplifier delivers reliable, high-quality audio distribution with the flexibility and performance that audio professionals demand.
