III. WARRANTY AND DISCLAIMERS
Instructions for the DDI-9 and DDI-10 DataPort Accessory Cards
QSC Audio Products, Inc. is not liable for any damage to speakers, amplifiers, or any other equipment that is caused by negligence or improper
installation and/or use of the DDI-9 or DDI-10 DataPort Accessory Card.
I. INTRODUCTION
The DDI-9 and DDI-10 DataPort Accessory Cards are designed for use with QSC’s four-channel CX and
DCA amplifiers. Both provide a relay-switched contact closure and opening if the amplifier fails, shuts
down, or is turned off, as well as means to remotely switch the amplifier on or into standby with a
remote pair of switch contacts. For inputs, both also provide both DataPort and Phoenix Connector
“Eurostyle” pluggable connectors.
The DDI-9 also allows muting of the amplifier’s four inputs, either individually or in groups, using remote
switch contact closures (Figure 1).

TECHNICAL ASSISTANCE
CHANNEL MUTING
With a DDI-9, any of the four inputs can be muted by making an electrical connection between the appropriate channel mute
terminal and the ground terminal. This allows you to use switches mounted remotely from the amplifier to mute channels.
You can mute and unmute multiple channels simultaneously with one switch by tying their respective connections together
to the single pair of switch contacts (Figure 2).
If you suspect that your DDI-9 or DDI-10 card is defective, check your system configuration and onnections to determine the origin of the problem. In
many cases, incorrect audio interfacing, poor cabling, or other system level impairments are the causes of problems in audio systems. For technical
assistance beyond the information given in this manual, contact the QSC Technical Services department.

Use this procedure to install the DDI-9 or DDI-10:
2
1.
Turn off the amplifier.
2.
Plug the card into the amplifier’s DataPorts. Use the four screws on each side of the DataPorts to secure it; do not overtighten them.
3.
To attach wires to the DDI-9 or DDI-10 terminal strip, strip about 5 mm (0.2”) of insulation from the wire. Twist the exposed wire strands
together and make sure there are no stray ones. Turn the screw on the terminal counterclockwise until you can fully insert the wire end into
the terminal. Turn the screw clockwise until the terminal clamps the wire securely. Repeat for all the wires needed.
4.
The amplifier is ready for use.
