Radio Design Labs TX-J2

The TX-J2 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-J2 may be mounted directly to a backboard or chassis using a variety of mounting options available from Radio Design Labs.

The TX-J2 is the ideal choice in installations requiring the passive mixing of two unbalanced line-level audio sources to feed a balanced (or unbalanced) audio output.

The TX-J2 is a complete unbalanced line-level audio input module. The front panel features two gold plated phono jacks, intended for mono or stereo consumer level sources. Inputs 1 and 2 are combined and balanced through audio transformers configured to reject induced hum. The line-level output is provided on the front-panel barrier block for connection to 10 kOhm or higher input impedance line-level module or equipment inputs.

Note: The TX-J2 is a passive module that does not add gain to the consumer level input. Therefore the balanced output level from the module is not a standard +4 dBu. For installations where a +4 dBu balanced line-level is required, or if the input level is particularly low, RDL’s TX-LC2 is recommended.

Features:

• Mix two unbalanced audio signals to mono balanced
• Combine stereo into mono with balanced output
• Unbalanced to balanced conversion without gain
• Hum cancellation on unbalanced line inputs
• Frequency response: 30 Hz to 20 kHz (+/- 1 dB)
