Professional AV installers often encounter projects that require long cable runs, and AudioControl is now shipping its BLX-1K balanced line transceiver (driver/receiver) to assist in these scenarios.
According to Washington-based AudioControl, the BLX-1K has been engineered as a premium, simple solution to efficiently address these challenges. The device is a signal extender that sends and receives a fully balanced, noise-rejecting, analog audio signal up to 1,000 feet over standard Cat 5/6 cable.
Designed to be used 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 Cat 5/6.
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, notes AudioControl, and has integrated mounting brackets. Product dimensions are 6.2 x 4.3 x 1.0 inches (W x D x H).
The company adds that 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 runs — indeed a true problem-solver for custom integrators.
