1.1 JBL Soundzone
Controller
1.2 Other Soundzone
Features
The JBL Z21S/Z32S Soundzone Controllers are specifically
designed for flexible routing and control of multiple audio sources.
To facilitate this, JBL has equipped the Z21S/Z32S with a wide
array of input and output capabilities.
The Z32S has inputs for three stereo line (-10dB RCA) sources
and a microphone input. The Z32S outputs two stereo signals, two
subwoofer signals, and an isolated auxiliary output, all on
Euroblock connectors. Both Z21S/Z32S convert the incoming -
10dB signal and boost it to the +4dB output required by profes-
sional grade amplifiers.
JBL's AutoWarmth™ and LevelGuard™ controls give you excel-
lent sounding, easy to use equalization and dynamics control.
This circuitry allows the signal to be tailored for a wide variety of
rooms, taste, and volume requirements.
These features allow you to bring the same audio quality many of
your patrons are used to hearing at home into the realm of busi-
ness. The Soundzone Controllers have been designed to make
them easier to operate than any other product in their class. In
reality the feature set provided by the Soundzone Controllers puts
them in a class by themselves.
Soundzone Controllers also feature linking capability. This is
accomplished by connecting standard Category 5 UTP cables to
the Soundzone's LINK jacks.
Linking of multiple controllers provides additional output zones yet
does not increase the number of inputs. SOURCE Linking simply
allows multiple controllers to share the same input source, elimi-
nating the need for Y-cables. Main linking allows multiple con-
trollers to share Paging Mic, Music Mute, and Direct Input func-
tions. When multiple units are linked, there is no master or slave
designation. The functions are simply paralleled so that Sources,
Paging Mic, Music Mute, and Direct Input can be run into ANY of
the linked Sound Zone controllers.
JBL offers several optional remote control wall plates -- the ZR-
3SV, ZR-2SV, and the ZR-V. These plates provide for remote
source selection and/or volume adjustments from within a zone
location.

2.1 Unpacking
2.2 Mechanical
Requirements
This product is carefully checked before packing to ensure flaw-
less appearance and operation and that it reaches you in first
class condition.
After unpacking the unit, please inspect it for any physical dam-
age. If any damage has occurred, notify your dealer immediately.
A written claim for damages can then be initiated. Please retain
the shipping carton and all the packing materials for use should
the unit need to be transported or returned for any reason.
Adequate ventilation must be provided by allowing sufficient space
around the sides, top, and rear of the Z21S/Z32S to ensure free
circulation of air. Forced cooling is not required. The Z21S/Z32S
requires a vertical rack space of 1U. Failure to do so may dam-
age the case and invalidate the warranty.

Power Supply Input
Connect your included JBL power supply here. The power supply
can be left loose or double-sided tape is provided for holding the
power supply in place. Alternatively, the installer can affix the
power supply with a bracket of their own making.
Zone Output(s)
The Z21S/Z32S outputs utilize balanced Euroblock connectors.
These outputs carry the Left, Right, and Subwoofer signals.
Connect these to your zone power amplifier
AutoWarmth™ Trim Pot
This trim pot adjusts at what point AutoWarmth™ is engaged
Page Assign
This allows you to assign pages between output Zones. This can
be accomplished with a simple remote selector switch or can be
hard wired if pages are to the same Zone every time. Shorting a
zone pin (Z1 or Z2 or both) to the “+” pin assigns the page to that
zone.
Music Mute
This can be wired to a switch that mutes the background music
when pin 2 is shorted to ground pin 1.
NOTE 1: MUSIC MUTE DOES NOT MUTE THE PAGING MIC. IN AN EMERGENCY SITUATION, THE SYS-
TEM USER MAY NEED TO USE THE PAGING MIC FOR EMERGENCY ANNOUNCEMENTS.
NOTE 2: WHILE MODEL Z21S DOES NOT HAVE A MUSIC MUTE JACK, IT CAN ACCEPT A MUSIC
MUTE THROUGH THE MAIN LINK CABLE. THIS IS FOR INSTANCES WHERE THE Z21S AND Z32S ARE
LINKED TO PROVIDE AN ADDITIONAL OUTPUT ZONE

Source Inputs
Connect your RCA equipped source signals here.
Microphone Input
Connect the paging microphone here. Line level paging inputs
from telephone systems must be externally transformer isolated
and reduced in volume to microphone level.
High Pass Filter
This switch activates the Zone output 100 Hz High Pass Filter,
which allows all frequencies above 100Hz to pass. Use this filter if
the bass response of your room is too boomy, when you are using
inexpensive loudspeaker transformers or in conjunction with the
subwoofer crossover (see subwoofer crossover section).
AutoWarmth™ Indicators
These indicators flash red when the AutoWarmth circuitry is being
activated.
Zone Remote Jacks
These inputs are for the optional Remote Wall Plates ZR-3SV, ZR-
2SV, and ZR-V.
Isolated Auxiliary Output
This sends a transformer isolated mono signal for a music-on-hold
system, or for a separate mono auxiliary Zone. The +/- outputs are
600 Ohm transformer isolated so that they can interface to another
system (telephone or remote amplifier) without having undesirable
ground interaction. The level control adjusts the output level to
match a variety of applications.
NOTE : AS SHIPPED, THE SOURCE FEEDING THE AUXILIARY OUTPUT IS SELECTED BY THE ZONE 1
SOURCE SELECTOR. WHATEVER SOURCE IS SELECTED BY ZONE 1 IS WHAT COMES OUT OF THE
AUXILIARY OUTPUT. THIS CAN BE CHANGED TO ALWAYS BE SOURCE 1 BY MOVING AN INTERNAL
JUMPER FROM Z1 TO S1.

Direct Input
The Direct Input signal is buffered and sent directly to the outputs.
This is useful for alarms, emergency pages, or for another priority
level of paging. The gain control adjusts the volume of Direct
Input to the Zones.
NOTE 1: THE DIRECT INPUT REQUIRES A LINE-LEVEL SIGNAL, A MICROPHONE PRE-AMP IS NEEDED
TO BOOST A MIC LEVEL SIGNAL BEFORE IT CAN BE RUN INTO THE DIRECT INPUT.
NOTE 2: WHILE MODEL Z21S DOES NOT HAVE A DIRECT INPUT JACK, IT CAN ACCEPT A DIRECT
INPUT SIGNAL THROUGH THE MAIN LINK CABLE. THIS IS FOR INSTANCES WHERE THE Z21S AND
Z32S ARE LINKED TO PROVIDE AN ADDITIONAL OUTPUT ZONE. IN THIS CASE A VOLUME CONTROL IS
PROVIDED FOR THE ADJUSTMENT OF DIRECT INPUT TO THAT ZONE.
Priority Hold
Priority Hold smoothly adjusts the time it takes for the normal input
source to become audible after the priority source ceases. This
allows for compatibility with the many different types of priority
sources that exist in business environments.
Link Jacks
These inputs allow you to network multiple Soundzone controllers
together. The units are connected by standard Category 5 UTP
cables.
Phantom Power
This switch provides +12V power for condenser microphones.

input.
Ducker
Ducking automatically decreases the level of the background
music when a page takes place. Set the Sensitivity control so that
the ducking occurs reliably whenever a mic page occurs. Set the
depth control to suit the application. Typical ducking would be with
the control straight up, letting through some of the background
music during a page. You can set the depth for full, minimal, or no
ducking of the music, as required.

5.3 Volume
5.4 AutoWarmth™
5.5 LevelGuard™
What is a Source? This is a line-level input signal such as pro-
grammed music, CD player, VCR/DVD, satellite feed, tape player,
radio, message repeater, or juke box. These sources are then
equalized, dynamically controlled, and routed by your selections
and priorities on the Soundzone Controller.
What is a Zone? This is the area where you wish the signal to
end up. The Z21S/Z32S outputs a stereo or mono signal to your
chosen Zone. Built-in subwoofer crossovers allow you to include a
subwoofer in that Zone. This allows you to attain the wide band-
width sound your patrons are used to hearing.
What is a good volume? Determining a good volume is a balance
of art and science. You need maximum coverage without interfer-
ing with the workplace environment or customer comfort and com-
munication. The Z21S/Z32S give you the tools you need in the
form of AutoWarmth™ and LevelGuard™ to get the best sound
quality from the volume that each application requires. Once you
have set your volume preferences, AutoWarmth™ and
LevelGuard™ help you keep it that way.
What is AutoWarmth™? In its simplest terms JBL's AutoWarmth™
can be thought of as being similar to the “loudness” control on a
home stereo, except it’s actual functions are considerably more
complex. AutoWarmth™ operates on a variable basis and auto-
matically makes the proper adjustments to maintain an even tonal
perception. This circuitry constantly adjusts for the ear's tendency
to hear less low frequencies at low volumes, and more low fre-
quencies at high volumes. AutoWarmth™ automatically ensures
full music fidelity at all volumes.
What is LevelGuard™? The LevelGuard™ circuitry helps keep
the volumes of various sources consistent by sensing the level of
the incoming audio source and automatically compressing the sig-
nal to a user selected preference.

6.1 Determining Source
Priorities
6.2 Connecting Sources
6.3 Adjusting Source Gain
6.4 Use Of EQ
Determining the hierarchy of your sources is easier than it sounds.
Generally it follows this order:
1. Emergency/Alarm (Direct Input with Music Mute engaged)
2. Pages (Paging Mic)
3. Pre-recorded announcements (or another source into Source 3
with Priority engaged).
4. Background music (Sources 1 and 2)
In this example, your alarms would connect to the Direct Input,
your Page Mic connects to the Mic Input,
pre-recorded announcements connect to Source 3,
and background music connects to Source 1 and 2.
NOTE: MUSIC MUTE DOES NOT MUTE THE PAGING MIC. IN AN EMERGENCY SITUATION IT IS USU-
ALLY BEST TO KEEP ALL MICROPHONES ACTIVE FOR ANNOUNCEMENTS.
Connecting your Sources is also very simple. Just connect the
Left and Right outputs of your Source to the Left and Right input of
the Soundzone Controller.
Check the input level LED’s, they should show green for continu-
ous signal. Red will flash if the input is too strong. Occasional
flashes into the red are not harmful if no distortion is apparent.
The best determination for needed equalization is to trust your
ears. Does the output sound boomy? Reduce bass setting or
engage the high pass filter, this will reduce the bass frequencies.
Does it sound dark or muffled? Turn up the treble. Or if it sounds
thin or harsh, decrease the treble. Just like the tone controls on a
car or home stereo.

The subwoofer outputs are low passed at 100 Hz with a slope of
24 dB per octave.
Traditional crossover: When the High Pass Filter switch is
engaged, then the main speakers are high passed at 100 Hz with
a slope of 24 dB per octave, forming a full traditional subwoofer
crossover. This traditional crossover configuration is recommend-
ed wherever possible, resulting in the smoothest frequency
response as long as there are enough subwoofers to keep up with
the main speakers.
Overlap crossover: When the High Pass Filter is NOT engaged,
then the main speakers receive a full range signal. this overlap
can allow for stronger mid-bass for installations where there may
not be enough subwoofers to cover the low end by themselves.
Care must be taken when using an overlap crossover because it
can result in a large mid bass bump in the range where both the
main and subwoofer speakers overlap. The size and nature of this
bump depends on the frequency response and rolloff characteris-
tics of the main loudspeakers. This bump can sound muddy and
may require a fairly sophisticated equalizer to remove, without also
removing too much of the bass content.
To set up AutoWarmth™ begin by turning the AutoWarmth™ trim-
mer to 12:00. Use this as your “baseline” setting. Now turn up the
Source volume (on front panel) to a typical operating level for that
Zone. Check the AutoWarmth™ indicator LED, on quieter pas-
sages the indicator should flash red. If it does not, start turning
the trimpot clockwise until it does. If the indicator is constantly on,
turn the trimpot counter-clockwise until it flashes only occasionally.
Then adjust the bass and treble tone controls for that zone. To
check the adjustments, turn the volume down to as low as its ever
going to be used in that zone and make sure the tone sounds full
enough. If not then turn the Autowarmth™ trimmer further clock-
wise to increase its effect. Go back and forth between typical
level, low level, and high level. Adjust AutoWarmth™ for the best
overall sound at all the compared levels.

An alternate method is to turn the AutoWarmth™ trimmer full
counter-clockwise. Turn the Source volume (on front panel) to the
highest volume at which that zone will be operated. Adjust the
AutoWarmth™ trimmer clockwise until the red LED just starts to
light on musical peaks. Then turn the AutoWarmth™ trimmer
back counter-clockwise until it does not light at all. Next turn the
zone’s level down to normal operating level and adjust the bass
and teble controls for that zone, the AutoWarmth LED will light.
With either of these setup methods, AutoWarmth™ should shut off
when operating at higher volumes and be lit at both normal and
lower volumes.
To set up LevelGuard™ begin by turning the LevelGuard™ trim
pot to 12:00. Use this as your “baseline” setting. Now turn up the
Source volume to the level desired for a particular Zone. Check
the LevelGuard™ indicator LED, on quieter passages the indicator
should be off. On peak volumes the indicator will flash amber. If
the indicator is constantly on, turn the trimpot clockwise until it
flashes only occasionally. It is useful to set LevelGuard™ so that
the LED stays unlit during very low volume music, flashes on and
off during normal volume, and then lights continuously as the vol-
ume increases. Adjust by ear to sound best.
Affix the security panel over the front panel setup controls to pre-
vent tampering.

SOURCE SELECTION
The Source Selection control on the wallplate only functions when
the Source Selector switch for that zone is set to “Remote” on the
controller. When the wallplate control is active, the red LED on the
wallplate below the Source switch (labeled Control Active) lights.
When this LED is not lit, the control is not operational.
VOLUME CONTROL
The Volume Control on the wallplate is ALWAYS operational,
regardless whether the Source Selector is active or not. This
control is ATTENUATE ONLY.
To set:
1. Turn the wallplate volume to maximum (full clockwise)
2. Set the volume control on the controller to the loudest you will
ever need the system to be.
3. Turn the wallplate volume control down to a comfortable or
typical operating level. Now the wallplate volume control cannot
turn the volume up above what is set on the controller.
