Rolls MB35 Promatch USB Direct Box Level Matcher

The MB35 converts stereo consumer level signals to professional line level signals - and vice versa. It may also serve as a balanced inline level control by patching the four RCA jacks together. IMPORTANT USB NOTE: When connecting the USB, your computer should recognize the connection. Rolls offer no support for using or setting up the USB, or interfacing with applications.
