Description

The TX-LC2 is the ideal choice in installations requiring the active, isolated mixing of two unbalanced line-level audio sources to feed a balanced (or unbalanced) audio line.

The input circuits are high-impedance, line-level (-10 dBV) and are isolated from each other. Therefore the modules may be used to bridge an unbalanced stereo source without affecting the stereo separation. The output from the TX-LC2 is a mono mix of the stereo signal. Gain of the combined signals is adjustable from -10 to +10 dB (rel. +4 dBu output).

The TX-LC2 may also be used to mix two separate sources into a single output. The mixing circuit in the module is an active summing amplifier.

The output driver provides a 150 Ω balanced source to drive high or low impedance, balanced or unbalanced lines. The TX-LC2 is operated from a 24 Vdc power supply, and with reduced headroom it may be operated from a 12 Vdc power supply.

The input connectors make connection of the TX-LC2 easy. The broad gain range makes the TX-LC2 ideally suited to any installation where a balanced mono signal is needed from a stereo unbalanced source, particularly low-output consumer products such as certain televisions.

Use the TX-LC2 individually, or combine it with other RDL modules and accessories as part of a complete audio/video system.
