INTRODUCTION AND FEATURES

INTRODUCTION

Congratulations on your purchase of
this Performance
processor! You have purchased a
product that embodies the best of what

®

JBL

engineers have learned about the
emotional power of audio reproduction
in more than fifty years of preeminence
in the field. This processor has been
designed and crafted to provide the user
with a high level of sonic performance.
Special attention has been paid to
minimizing the number of components
in the audio signal path, resulting in
extremely low distortion, excellent
transient response and wide dynamic
range. JBL products set new bench­marks in audio technology and,
when used as part of a complete JBL
Performance Series system, will bring
the ambience and acoustics of some of
the world’s greatest concert halls and
theaters into your home.

To obtain the best performance from this
processor, please be sure to completely
read this user’s manual and use the JBL
BassQ processor only in accordance
with its instructions.

™

Series JBL BassQ

™

FEATURES

The JBL BassQ processor features
the following:

Minimum Phase Distortion

The algorithms used to calculate and
correct the room modes are designed
to give the best results with the least
amount of phase-induced distortion.
This is unique to the JBL BassQ
processor and is not available from
any other product.

Mono or Stereo Inputs

Supporting both LFE and stereo sub­woofer inputs allows for a greater
range of applications and allows the
JBL BassQ unit to be used with a variety
of different processors. Although the
system has been designed to work
with the rest of the Performance Series
system, including AV1 and AVA7,
the unit can be used in almost any
system and can improve the in-room
response of almost any installation.

Multiple Subwoofer Outputs

Up to four subwoofers can be optimized.
Multiple subs allow better seat-to-seat
response and can greatly improve
the listening experience over a single
subwoofer. The JBL BassQ unit allows
optimizing multiple subs to achieve
the most accurate in-room response
possible.

Auto Turn-On and Power-Sequencing

Due to the high current demands of
power amplifiers at the instant of
turn-on, the JBL BassQ processor is
equipped with a power-sequencing
circuit that turns on each amplifier in
a delayed sequence, avoiding the large
instantaneous current demand (and
possible circuit breaker tripping) that
could otherwise occur, should more than
one amplifier turn on at the same instant.

Multiple Microphone Inputs

Multiple microphones allow for the
optimization of multiple seats. This
results in a larger listening area that
benefits from a more accurate room
optimization.

Two Listening Curves

Two different playback curves have been
implemented to better match the type of
playback material. Cinema mode closely
follows the standard for playback curves
used in commercial cinemas and scoring
stages. This will allow the system to
closely match the experience of the
directors and producers of popular films
and TV shows. Music mode is a gentler
playback curve that better mimics the
frequency response in most music
production studios.

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 turn­on 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

then connect all components in daisy­chain 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 sig­nal 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.

1111 1714

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 sub­woofers are used, the additional sub­woofers 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.

GENERAL INFORMATION

A JBL Performance Series system
installation incorporates one preamp/
processor (AV1 or AV2), one power
amplifier (AVA7) – in addition to the
amplifier(s) used to power one or more
subwoofers – and one JBL BassQ
processor. If your speaker complement
includes the Performance Series
PS1400 powered subwoofer (or other
powered subwoofer), you may use the
amplifier included in each subwoofer.
If you are using a passive subwoofer,
you will need to supply a subwoofer
amplifier. All seven channels on the
AVA7 are to be used for driving the left,
center and right, and both side and
both rear speakers.

Use the simplified wiring diagram below,
which illustrates how to connect the
JBL BassQ unit to a Performance Series
system. This diagram is intended to show
the signal flow through the system.

PHYSICAL INSTALLATION

Installation of the JBL BassQ
unit is a straightforward process.

IMPORTANT:

The JBL BassQ unit must be installed
following the directions below.

Always put amplifiers on the bottom
of a stack.

not be supported solely by the front­mounting locations.

1. The JBL BassQ unit has been
designed to be mounted in
EIA-standard racks, or stacked
freestanding. If the unit is being
mounted in a rack, it is recommended
that its feet be removed prior to
installation. If it will be stacked with
other components, use the feet that
came attached to the unit. This will
ensure that there is sufficient space
underneath so that heat can be dissi­pated effectively. Two rack ears are
included with the JBL BassQ unit.
To install these rack ears, remove the
two machine screws on each of the
two side panels (see drawing), hold
each rack ear in place, and attach it
to the unit using the same two screws.
Make sure that these screws are
securely tightened.

2. Make sure that the unit is located
in a well-ventilated, cool area. If it
is installed inside a cabinet that is
enclosed on all sides, the front of the
cabinet must remain open to allow
sufficient flow-through ventilation
to avoid overheating.

3. With the help of another person to
guide the unit into the rack, gently
slide the JBL BassQ unit into place.
Align the rack mounting holes to the
rack ears of the equipment rack.

Once you have connected the sub­woofer input into the JBL BassQ unit
and connected the outputs from the unit
to all subwoofers in the system, you will
need to run the BassQ test to finalize
the room calibration and correction.

Before You Begin

It is very important that all subwoofers
are on and installed before you run the
BassQ process. If you move a sub­woofer or add a sub to the system, you
will need to rerun the test. Set all initial
settings on all attached subwoofers or
subwoofer amplifiers to nominal or 0dB
input level (phase set to 0°) and bypass
all internal crossovers.

If Your System Includes an AV2

Before beginning any calibration, select
BASSQ ->Yes from the AV2 Setup menu.
This will optimize the delay settings and
AV2 Autocal for use with the JBL BassQ
processor. It will be necessary to manu­ally set the subwoofer output level from
the AV2 processor. See the AV2 manual
for details.

Step One: Microphone Setup

Begin the calibration process by setting
up the microphone array to test the
listening area. The JBL BassQ unit
includes four microphones, four micro­phone bases and eight microphone
stands. Begin by screwing together
two stands to make four tall stands.
Press the poles firmly into the base.
The hole in the base will securely hold
the stand, but you should make sure
that the stand is in the base before pro­ceeding. Next, screw one microphone
each into the top of the stand. Each

microphone comes with an attached
cable with a 1/4" jack on the end. Plug
each microphone into the front of the
JBL BassQ unit, using the diagram
below as a reference for placement.
It is important that the microphones
cover the listening area.

Step Two: Turn On All Electronics

Make sure that all electronics are on,
including all subwoofers or subwoofer
amplifiers. Turn down or mute the vol­ume on the preamp.

NOTE: Many self-powered subwoofers,
such as the PS1400 and HTPS-400, have
auto turn-on based on signal sensing.
Either turn them to

On or make sure
that they are on and remain on for this
test. If the subwoofers are not already
on, the first part of the test tone will be
clipped and BassQ will not properly
calibrate the room.

Step Three: Begin the BassQ Process

The first time you power up the JBL
BassQ unit, the blue light will be off and
the unit will be in Bypass mode. Press
the BassQ button. The BassQ light will
begin to blink, indicating that it has
started the process. You will hear a test
tone from each subwoofer, one at a
time. When the process is finished,
the BassQ light will be solid and the
subwoofer lights will flash briefly to
indicate which outputs have subwoofers
attached and are calibrated. You can
confirm which outputs are calibrated by
placing the unit into Standby mode and
then on again. The lights will go on briefly
to indicate which outputs are active.

NOTE: When using an AV2, it is important
to run the Autocal only after using the
BassQ process and setting the BassQ
setting to

Yes in the AV2 setup menu.

See the AV2 manual for details.

Step Four: Level Calibration of
Main Speakers

Level adjustments are best done using
an SPL meter that is set to C-weighting
and Slow response. Set the level control
on your subwoofer to 0dB or a nominal
reference level. Turn on the internal
noise test from the AV1 (or other
processor) and, using the level control
in your preamp or processor, set all
speaker levels to a 75dB reference
level. If using the AV2 Autocal, the levels
will automatically be set. Be sure to set
the AV2 to

Yes for BassQ in the AV2

setup menu.

Step Five: Distance Calibration

Due to the different distances between
the listening position for the subwoofer,
the front channel speakers and the sur­round speakers, the amount of time it
takes for sound to reach your ears from
front speakers versus surround speakers
differs. You may compensate for this
difference through the use of the delay
settings to adjust the timing for the
speaker placement and acoustic
conditions in your listening room or
home theater. Begin by measuring
the distance between your listening
position and each of the speakers in
your system. Write these down, as you
may need to remember them in the
future. If you have more than one
subwoofer, it is best to place them
an equal distance from the listening
position. If this is not possible, use the
distance from the closest subwoofer
for the speaker distance settings. If
using the AV2 Autocal, the distances
will automatically be set. Be sure to
set the AV2 to

Yes for BassQ in the AV2

setup menu.

Step Six: Enjoy the Music

You can now disconnect all the micro­phones and pack up the stands. Keep
these, in case you need to rerun the
test. Unmute the preamp and enjoy.
