Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC
power inlet on the back of the RAVE 520uz. 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 520uz,
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 recep-
tacle with the lock-tab oriented toward the bottom of the RAVE
520uz 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
RAVE 520uz 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 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 recep-
tacles. 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.
Each input has software-selectable +48V phan-
tom power. Use caution when connecting equip-
ment (particulary unbalanced equipment).
Omni In
The six Omni In connectors are two-pin terminal block connectors.
They accept contact closure, TTL logic signals, 0-5 VDC control volt-
ages, 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 recommen-
dations. 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 connec-
tors. They provide CMOS logic level compatible signals for external
devices.
