Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC power inlet
on the back of the RAVE 522ua. Plug the AC line connector into the AC out-
let. 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 522ua, 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 522ua 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 522ua 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-sele48V phantom power. 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.
Each input has software-sele48V phantom
power. Use caution when connecting equipment (par-
ticulary unbalanced equipment).
Analog Outputs
Eight balanced audio inputs are provided, CH 1 OUTPUT - CH 8 OUTPUT.
Plug the output signal terminal block connectors into the output recepta-
cles. 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
accept contact closure, TTL logic signals, 0-5 VDC control voltages, or 10k
ohm variable resistors. The contact closure and logic devices accommo-
date on/off or state-change events; the variable resistor input provides full
8-bit resolution allowing for incremental-change events. Refer to the illus-
trations 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 connectors.
They provide CMOS logic level compatible signals for external devices.
Analog audio input and out-
put- balanced connection.
Logic Out connections.
Negative (-) terminal is at
chassis potential. Positive
(+) terminal logic level is
switched using software.
CobraNet and QSControl
connection. Accepts rug-
gedized or normal shell-
less RJ45 plugs.
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.
Analog audio input and
output- unbalanced con-
nection. Note jumper wire
between - and ground.
