Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 722az. 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 supplied with your 722az, 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 BASIS 722az 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.

Analog Audio Inputs

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

Omni In

The six Omni In connectors are two-pin terminal block connec- tors. They can accept contact closure devices (switch, relay contacts), 10k ohm variable resistors, TTL logic level, and 0-5 VDC input.

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 chassis or the - pin.

Logic Out

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

Relay Out

Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT 2. Contacts are floating and rated for 30VDC, 1A. There is one common terminal, one normally-closed contact ter- minal and one normally-open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is connected to the NC terminal and the NO terminal is not connected; when the relay is ener- gized the C to NC connection is opened and the C to NO connec- tion is closed.

QSControl connection. Accepts ruggedized or normal shell-less RJ45 plugs.

Analog audio input- balanced connection.

Analog audio input- unbalanced connec- tion. Note jumper wire between - and ground.

Omni In connections. Variable input must be 10k ohm variable resistor. Contact clo- sure input can be a switch or relay con- tacts. These inputs can operate software “devices”. Negative (- ) terminal is at chassis potential.

Logic Out connections. Negative (-) terminal is at chassis potential.

Positive (+) terminal logic level is switched using software.

Relay Out connections. Refer to text, at left, for explanation.
