RDL TX-1A Reviews

A must-have for remote unbalanced gear.

This is basically a reverse DI-box. Our church has two of these devices which we use to feed audio from our worship services to other parts of the building. One of these endpoints optionally accepts a balanced signal, but doing so caused a ground loop. We're using the TX-1A to isolate that connection. The other endpoint is a cheap Radio Shack paging amplifier which only accepts an unbalanced input. The TX-1A does the job there as well. The built-in attenuator is a big bonus, allowing the use of cheap consumer -10dBV gear (such as our paging amplifier). One thing to note, the devices we received have Phoenix connectors instead of standard screw terminals. This is actually better in my opinion, since those are a bit easier to work with. But just wanted to point out the difference from the item as pictured.

Used to take consumer audio (eg PC audio output) which is balanced and convert to unbalanced with simple adjustment to optimize sound quality.
