Product Description
RDL TX-J3 Unbalanced Input Transformer
Overview
The TX-J3 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-J3 is a complete unbalanced line-level audio input module. The front panel features two gold plated phono jacks and a Mini-jack input, intended for mono or stereo consumer-level sources. When a Mini-jack is plugged into the TX-J3, the RCA input jacks are disabled. Inputs 1 and 2 (Mini-jack L and R) 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-J3 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-J3 is the ideal choice. Use it individually or in conjunction with other RDL products as part of a complete audio/video system.
