Unbalanced Input Transformer - Unbalanced stereo inputs to summed balanced mono output

• 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)

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 detachable terminal block for connection to 10 kΩ 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.

Wherever consumer format audio signals need to be converted to a balanced line without gain the TX-J2 is the ideal choice. Use it individually or in conjunction with other RDL products as part of a complete audio/video system.
