RDL TX-LC2 Unbalanced to Balanced Line Combiner

Unbalanced to Balanced Line Combiner 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 ea
