Connections
AC Power Cord
Insert the molded receptacle of the AC power cord into the AC power inlet on the
back of the BASIS 922az. 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 922az, con-
tact 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 BASIS 922az 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 922az 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) or 10k ohm variable resis-
tors. The contact closure and logic devices accommodate on/off or state-change
events; the variable resistor input provides full 8-bit resolution allowing for incre-
mental-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 connectors. They pro-
vide CMOS logic level compatible signals for external devices.
Relay Out
Two sets of relay contacts are provided,
RELAY OUT 1
and
RELAY OUT 2
. Con-
tacts are floating and rated for 30VDC, 1A. There is one common terminal, one nor-
mally-closed contact terminal 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 energized the
C
to
NC
connection is opened and the
C
to
NO
con-
nection is closed.

Logic Out connections.
Negative (-) terminal is
at chassis potential.
Positive (+) terminal
logic level is switched
using software.
CobraNet and
QSControl con-
nection. Accepts
ruggedized or
normal shell-less
RJ45 plugs.
Omni In connec-
tions. Variable
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 chassis poten-
tial.

unbalanced connec-
tion. Note jumper
wire between - and
ground.
