If you need to convert your UNBALANCED consumer grade audio device to a BALANCED XLR output then the Whirlwind LM2B level matcher is perfect for the job!
The LM2B will take the output from your unbalanced semi-pro equipment and "up convert" your IHF signal by 14dB and providing a balanced XLR output.
Unbalanced Inputs
2x RCA (White/Red) - Gold Plated
3.5mm TRS
