QSC Audio DSP 322UA Connections, AC Power Cord, QSControl, Analog Universal Audio Inputs, Omni In

Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the DSP 322ua. Plug the AC line connec- tor into the AC outlet. The power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes. If a different type of IEC power cord is required than the one supplied with your 522aa, contact QSC’s Technical Services Department.

QSControl

Connect one end of a category-5 cable terminated with an RJ45 plug into the QSControl receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the DSP 322ua and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate QSControl.net network port.

QSControl connection: accepts ruggedized or normal shell-less RJ45 plugs.

Analog Universal Audio Inputs

Eight balanced audio inputs are provided, CH 1 INPUT - CH 8 INPUT. They accept everything from mic level to line level signals and are equipped with software-selectable +48V phantom power. Plug the input signal terminal block connectors into the input receptacles. Connection pin-out is printed on the rear label for ref- erence. Refer to the illustrations for balanced and unbalanced con- nections. Use balanced audio inputs whenever possible.

Each input has software-selectable +48V phan- tom power. Use caution when connecting equip- ment (particularly unbalanced equipment).

Analog Audio Outputs

Eight balanced audio inputs are provided, CH 1 OUTPUT - CH 8 OUTPUT. Plug the output signal terminal block connectors into the output receptacles. Connection pin-out is printed on the rear label for reference. Refer to the illustrations for balanced and unbal- anced connections. Use balanced audio inputs whenever possible.

Omni In

The six Omni In connectors are two-pin terminal block connectors. They accept contact closure, TTL logic signals, 0-5 VDC control voltages, or 10k ohm variable resistors. The contact closure and logic devices accommodate on/off or state-change events; the vari- able resistor input provides full 8-bit resolution allowing for incre- mental-change events. Refer to the illustrations for connection recommendations. NOTE! +48 volts is the absolute maximum that can be applied to the + pin without damage. Voltage is with respect to chassis or the - pin.

Omni In connections. Vari- able input must be 10k ohm variable resistor. Contact closure input can be a switch or relay contacts. These inputs can operate software “devices”. Nega- tive (-) terminal is at chas- sis potential.

Logic Out

The four Logic Out connectors are two-pin terminal block connec- tors. They provide CMOS logic level compatible signals for external devices.
