Balanced Line Transceiver

BLX-1K

Professional A/V installers often encounter projects requiring long cable runs, and the BLX-1K has been engineered as a premium, simple solution to efficiently address these challenges. The BLX-1K is a signal extender that sends and receives a fully balanced, noise-rejecting, analog audio signal up to 1000 feet over standard CAT5e/6A cable.

Designed for use in pairs at both ends of the signal path, each BLX-1K contains a 2-channel receive stage as well as a 2-channel transmit stage, enabling audio to travel in both directions across a span of standard CAT5e/6A. Once wired connections are made, the A/B button on one unit is pressed to reverse the signal path. Signal gain can then be set to complete the installation. The BLX-1K comes equipped with a 24 VAC transformer for easy connection and ultra-quiet performance.

The BLX-1K delivers a stout output of nearly 8 Volts rms with an exceptionally low noise floor, providing a pure, crystal clear audio signal over long Ethernet runsthe ultimate problem-solver for A/V installers.
