Connections

AC Power Cord

Insert the molded receptacle of the AC power cord into the AC power inlet on the back of the BASIS 914lz. 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 914lz, contact QSC’s Technical Services Department.

CobraNet and QSControl connection. Accepts rugge- dized or normal shell-less RJ45 plugs.

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 BASIS 914lz and push firmly until the connector locks into place (usually an audible “click” can be heard). Connect the other end to the appropriate CobraNet network port.

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 914lz 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

Four balanced combo (XLR/TRS) inputs are provided, CH 1 INPUT - CH 4 INPUT. They accept line level signals. Plug the input signal XLR or 1/4” TRS 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 two Omni In connectors are two-pin terminal block connectors. They accept contact closure, TTL logic sig- nals, 0-5 VDC control voltages, or 10k ohm variable resistors. The contact closure and logic devices accom- modate 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.
