The main function is to convert balanced +4dBu signals to unbalanced and back again.
*It's an insert station. Insert your balanced gear such as guitar pedals and old echo fx into your DAW or consol.
*It's an active DI-box with up to 26dB of gain. Plug your favourite instrument into your collection of vintage gear via the TC1.
*It's a re-amping tool.
*It's a Swiss Army Knife on stage. Hook up balanced gear on stage between your instrument and amp.
The TC1 does not use any transformer so it does not add any color to your sound.
