QSC Audio 522AA Connections, AC Power Cord, CobraNet, QSControl, Analog Audio Inputs and Outputs

Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the RAVE 522aa. Plug the AC line connector 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.

CobraNet

Connect one end of a category-5 cable terminated with a RJ45 plug into the CobraNet receptacle. Insert the RJ45 plug into the receptacle with the lock-tab oriented toward the bottom of the RAVE 522aa and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate Cobra- Net network port.

CobraNet and QSControl connection. Accepts rug- gedized or normal shell- less RJ45 plugs.

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 RAVE 522aa and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate QSCon- trol.net network port.

Analog Audio Inputs and Outputs

Eight balanced audio inputs and outputs are provided, CH 1 INPUT - CH 8 INPUT and CH 1 - CH 8 OUTPUT. Plug the input signal terminal block connectors into the input recep- tacles. Connection pin-out is printed on the rear label for reference. Refer to the illustrations for balanced and unbal- anced connections. Use balanced audio connections when- ever possible.

Omni In

The six Omni In connectors are two-pin terminal block con- nectors. They can accept contact closure devices (switch, relay contacts) or 10k ohm variable resistors. The contact closure and logic devices accommodate on/off or state- change events; the variable resistor input provides full 8-bit resolution allowing for incremental-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 chas- sis or the - pin.

Logic Out

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

Analog audio input- unbal- anced connection. Note jumper wire between - and ground.

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 connections. Negative (-) terminal is at chassis potential. Positive

(+)terminal logic level is switched using software.
