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 each 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 unity to 14 dB.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 input connectors make connection of the TX-LC2 easy. The 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.
