Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC
power inlet on the back of the RAVE 520az. 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 520az,
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
520az 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 520az 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 connectors.
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 resolu-
tion allowing for incremental-change events. Refer to the illustra-
tions for connection recommendations. NOTE! +48 volts is the
absolute maximum that can be applied to the + pin without dam-
age. 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.
