11. Main Power Switch
Place this switch in the On position at
all times during normal use.
12. Power Trigger Input Jack
When using the JBL BassQ processor
in a JBL Performance Series system
with the AV1 digital surround processor,
you will need to use the trigger cable
set included with the AV1. Connect the
DIN end of the cable to the Trigger
Output DIN jack on the rear panel of the
AV1, and connect the 1/8" (3.5mm) plug
to the Trigger Input Jack
B on the rear
panel of the JBL BassQ unit.
If the JBL BassQ unit is used with
another component (such as the AV2)
that uses a trigger for automatic turn-
on and turn-off, make sure the other
component’s output is between 3 and
24 volts DC. Connect the trigger output
jack on the other component to the
1/8" (3.5mm) Trigger Input Jack
B on
the JBL BassQ unit using the cable
included with the JBL BassQ unit.
Whenever a power-on trigger is used
to operate the JBL BassQ processor,
make sure that the JBL BassQ Main
Power Switch
A is in the On position.
If the Trigger source (AV1 or another
source unit featuring power-on trigger)
is on, the JBL BassQ LED Standby
Indicator ™ will glow blue. If the
Trigger source is off or in Standby,
the JBL BassQ unit will also go into
Standby and its LED Standby Indicator
™ will turn red.
The remote control
will overide the trigger input.
13. Power Trigger Outputs
If you wish to have other components
in your system turn on via trigger,
make sure they are compatible with
the 1/8" (3.5mm) 12-volt DC Trigger
Output Jack
C on the JBL BassQ
unit. If they are, you may connect the
Trigger Output Jack
C to the first
component’s trigger input using one of
the cables included with the JBL
Performance Series AVA7, and
then connect all components in daisy-
chain fashion.
There are five trigger outputs on the
rear panel of the JBL BassQ unit.
• Pass-through sends the 12-volt trigger
signal out in parallel to the input.
Use this to trigger the AVA7 amplifier,
or the first amplifier you are using in
the system.
• 2S sends the 12-volt signal 2 seconds
after the input is received.
• 4S sends the 12-volt signal 4 seconds
after the input signal is received.
• 6S sends the 12-volt signal 6 seconds
after the input signal is received.
• 8S sends the 12-volt signal 8 seconds
after the input signal is received.
14. Movie Trigger Input
Using a 12-volt trigger from the Movie/
Music switching can be automated.
If you are using the AV1 processor,
use the DIN-to-mini trigger cable
included with the AV1, as this switching
is already programmed into the trigger
outputs of the AV1. If you are using
the AV2 or another component that
has a programmable trigger, use the
2.5mm to 3.5mm cable included with
the JBL BassQ unit.
The remote control
will overide the trigger input.
15. Subwoofer Inputs
There are two subwoofer inputs.
If using an AV1 processor or other
processor that has a single subwoofer
or LFE output, connect the subwoofer
output to the Left input and set the input
mode to Mono on the front panel of the
JBL BassQ unit. Do not connect the
input to the Right input jack, as no sig-
nal will be processed. If you are using
a preamp/processor such as the AV2,
or an AVR that has stereo subwoofer
outputs, connect the left and right
inputs and set the mode to Stereo on
the front panel of the JBL BassQ unit.
16. Subwoofer Outputs
There are four subwoofer outputs.
These correspond to two subwoofers
per side. For best performance,
it is recommended that you use at
least two subwoofers placed in the
front left and front right corners of the
room. These would use the L1 (Left 1)
and R1 (Right 1) outputs. If four sub-
woofers are used, the additional sub-
woofers would be connected to the
L2 (Left 2) and R2 (Right 2) outputs. If
stereo input is used, the left and right
outputs will pass through the respective
input signal as a stereo subwoofer.
17. AC Inlet
Your JBL BassQ processor is shipped
with an IEC-type, removable power
cord that mates with the AC inlet on the
rear panel. To ensure proper operation,
use the supplied power cords. The JBL
BassQ processor is a multivoltage unit
and can operate from 110 to 240 volts,
50Hz to 60Hz. Two cords are supplied.
One is a 120-volt cord for use in North
America, and the second is a generic
cord, which requires that the correct
mating plug be attached for your
country’s specific type.
18. RS-232 Port
This port is for factory use only. No
user features are available at this time.
