5. APPLICATION
5.1 Using the SM DI4 as a DI Box (direct injection unit)
Connect the signal you would like to convert from unbalanced to balanced to the SM DI4 via a
1/4 inch unbalanced jack 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 SM DI8 and connect
to your chosen destination.
If the input signal strength is too "hot" (high) you can depress the 20dB PAD switch to adjust to a
more appropriate level.
If there is an earth loop hum you can remove by depressing the earth lift switch. For Extra
grounding in a studio we have included a Ground Screw on the back of the unit.
5.2 Using the SM DI4 as a line mixer
You can mix volume & pan of all input signals to a single stereo pair of RCA connections on the
rear of the SM DI4. This enables use of the unit as a fully functional line mixer. This can be very
handy for many applications both live and in the studio.
Just connect the RCA stereo master outputs on the rear to your chosen destination (eg. Monitor
amplifier) and adjust the individual volume and pan controls for each individual channel on the
front of the SM DI4 to suit your needs.
A master volume control is provided on the front panel in addition to the individual controls.
Adjust this as necessary.
A Headphone output is also provided on the fron of the unit
