The Manley TUBE DIRECT INTERFACE models feature exceptionally clean and quiet tube circuits which will warm up any electric guitar, bass, violin, and especially those sterile sounding synths. Unique with the Manley Tube DI's is the added 5-position high pass shelf EQ, there to fight unwanted resonances. As splitter devices, the transformer-coupled balanced XLR output can be sent directly to a mic level input, such as through your console channel, while the 1/4" output drives the guitar amplifier cabinet which can be miked and mixed with the direct feed. Low impedance outputs, Ground lift and Console Out Boost switches make these units both versatile and compatible. Keep your Manley DI close at hand to get that noisy high impedance guitar cable into quiet lo-Z territory fast!
We offered both Mono Single Channel and Stereo 2-channel versions.

This guy needs to find the bolt for the power tranny and screw it back in...
