It converts two unbalanced 1/4" inputs into two balanced XLR outputs, providing impedance and signal matching for direct connection of instruments to mixers and amplifiers.
It can function as a signal splitter, allowing you to feed two separate mono signals, a stereo signal, or a split signal to two separate amps.
It includes a groundlift switch and a 3-position input attenuator (0dB, 20dB, 40dB) to handle various input levels, even allowing direct connection to a guitar amp's speaker output.
It can be powered by either a 9V battery or phantom power from a mixer (+18 to +48 V DC).
