BUC 102 Two Channel Audio BUC - Balanced and Unbalanced Converter
Description The Extron BUC 102 Balanced and Unbalanced Audio Converter provides signal matching between unbalanced and balanced audio equipment. In addition to serving as an interface between professional AV systems and consumer products, the BUC 102 is a high-quality line driver for sending and receiving audio signals over long distances.
Specifications Audio Gain
Unity (0 dB) when the BUC 102 is set to the default gain adjustment and the DIP switch is set to match the output wiring. DIP Switch Setting
Features
Unbalanced Balanced
• Provides signal matching between unbalanced and balanced audio equipment • Audio line driver • Allows transmission of balanced audio signals up to 1,000 feet (300 m) through Extron STP20 cable • Gain control for each channel with a wide adjustment range from -80 dB to +20 dB • Gain compensation switch for interfacing between professional AV systems
