Recommended Accessories

Radio Design Labs' TX-LC2 is part of the group of versatile TX series products from Radio Design Labs. The TX series feature the advanced circuitry for which RDL products are known, combined with durable, quality connectors. The ultra-compact TX series can be mounted in limited space using the adhesive methods popularized by RDL's STICK-ON™ series. The TX-LC2 may be mounted directly to a backboard or chassis using a variety of mounting options available from RDL.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

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 output.

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 output driver provides a 150 ohm balanced source to drive high or low impedance, balanced or unbalanced lines. The TX-LC2 may be operated from any power supply voltage between 24 Vdc and 33 Vdc, and as low as 12 Vdc with reduced headroom. The module's normal operating voltage is 24 Vdc.

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 Rack-Up®, STICK-ON, or TX series audio or video modules as part of a complete audio/video system.

Radio Design Labs TX-LC2 Features:

  • To Mix 2 Unbalanced Audio Signals to Mono Balanced
  • To Combine Stereo Into Mono with Balanced Output
  • A Gain Trim For an Output
  • Isolation between Inputs
  • Unbalanced to Balanced Conversion
