TX-LC2 Unbalanced to Balanced Line Combiner

TX-LC2 Unbalanced to Balanced Line Combiner

Radio Design Labs - Unbalanced to Balanced Line Combiner


How to buy this product

  • Mix 2 Unbalanced Audio Signals to Mono Balanced
  • Combine Stereo Into Mono with Balanced Output
  • Output Gain Trim
  • Isolation Between Inputs
  • Unbalanced to Balanced Conversion
  • High‑Quality Audio

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.
