1.2A Installation

For most applications the D4 should be installed in a rack frame so that you can tap
the Preview button without causing the unit to slide around. The D4 generates very
little heat so it is not necessary to leave an empty space for ventilation above or
below the unit.

1.2B Hook Up Audio (rear panel)

1. Turn down the master volume control of your monitoring system, PA, mixer,
instrument amp, etc.
2. Turn down the D4's front panel volume control.
3. Connect the D4's Main stereo outputs to a suitable stereo monitoring system or
mixer.
4. The D4's Aux jacks can provide additional outputs for selected drums. To use
these optional outputs, patch them into your monitoring system or mixer.
5. To monitor via headphones, plug them into the front panel Phones jack. If you
monitor only through headphones, it is not necessary to hook up the Main and/or
Aux outputs.
Note: The front panel volume control simultaneously sets the level of the Main, Aux,
and Headphone ouputs.

1.2C Hook Up MIDI (rear panel)

MIDI commands can trigger the D4's drum sounds, select different Drum Sets, and
control the overall level.
1. Connect the MIDI Out from the source of MIDI data (sequencer, MIDI drum pads,
trigger-to-MIDI converter, keyboard, etc.) to the D4's rear panel MIDI In.
2. To distribute the MIDI signal present at the D4's MIDI In to other units, connect
the D4's MIDI Out/Thru to the other units' MIDI In. MIDI Out has other
applications, as described in section 4.2.
