Applications
Using the di4 as a Direct Box
Connect the signal you would like to convert from unbalanced to balanced to the di4 via a 1/4 inch unbalanced cable to one of
the channel inputs on the front panel of the unit. Connect an XLR balanced cable to the corresponding channel output on the
rear of the di4 and connect to your chosen destination. If the input signal strength is too high you can engage the attenuation
switch to pad the signal by 20dB-40dB. If there is ground loop hum you can remove it by engaging the ground lift switch.
Using the di4 as a Stereo Mixer
You can mix level and pan of all input signals to a single stereo pair of RCA connections on the rear of the di4.
This enables use of the unit as a fully-functional line mixer. Just connect the RCA stereo master outputs on the rear to your
chosen destination and adjust the individual level and pan controls for each individual channel on the front of the di4 to suit
your needs.
