FreeSpace® IZA 2120-HZ
The four-input IZA 2120-HZ mixer-amplifier is optimized for dual-zone high-impedance applications. It
has the ability to independently adjust the EQ, bass/treble level, and volume control (with A/B source
selection via two remote controls) for each zone.
This mixer-amplifier supports loudspeaker EQs for the FreeSpace FS3/HPF, DS 16, DS 40, and the larger
DS 100 and FS3B. Since each output supports an independent EQ, the amplifier has the ability to bi-amp
by driving a DS loudspeaker with EQ on one channel and an FS3B with EQ on the second channel, or any
required combination.

Installation
Importance of Proper Ventilation
For placement of the amplifier, keep the following in mind:
• Make sure that air can circulate freely from left to right for adequate ventilation. There are vents on the
sides.
• The temperature of the rack should be controlled to ensure that amplifiers are not exposed to ambient
temperatures exceeding 40° C (104° F).
• Do not cover or block amplifier vents.
• Do not place the amplifier in an enclosed space, such as a cabinet.
• Make sure the chassis is protected from heat and kept away from direct heat sources, such as heating
vents and radiators.
CAUTION: Do not allow the chassis to exceed the maximum operating temperature of 40°C
(104°F). Be aware of conditions in an enclosed rack that may increase the temperature above
room-ambient conditions. If the amplifier becomes too hot, it will go into a thermal protection
mode and mute all outputs.
Rack Mounting
FreeSpace® amplifiers are designed to fit standard 19-inch (48cm) rack equipment, occupying 1 rackunit (RU) in height, requiring a mounting depth of 12.2 inches (30.9cm) from the front rack rail. Use four
fasteners with washers (not supplied) to mount the amplifier front panel rack ears to the equipment rack
rails.
CAUTION: Only use the mounting hardware recommended by the rack manufacturer.
Removing Rack-Mount Ears
Rack-mount ears can be removed by removing the three screws from each rack-mount ear.
Figure 9. Removing the rack-mount ears
Installation Guide - 23
Installation
pro.Bose.com
Placing on a Flat Surface
The amplifier can be placed on a flat, stable surface like a table, counter, or shelf. The rack-mount ears can
be removed and plastic feet (included with the amplifier) can be installed to protect the surface area and
prevent the chassis from sliding.
Note: When installing the amplifier in an oce, conference room, or classroom, carefully place it in a way
that minimizes the audible aects of the internal cooling fan of the amplifier. It is recommended to place
the amplifier below ear level, in a corner, with the fan inlet (left side) pointing away from the seating area.
Installing the Feet on the Amplifier
The included feet are comprised of two parts: a foot and a pin.
1. Place the amplifier upside-down on a flat, level surface on a protective covering to avoid scratching the
top of the chassis.
2. Insert the four feet into the four holes on the bottom of the chassis.
3. Insert a pin into the hole on the foot.
4. Press down on the pin until the foot locks into place. Repeat for all four feet.

Configuration example #3
REMOTE 1 can be a Bose volume control with A/B switch user interface accessory (PC 041967) and
REMOTE 2 can be a volume control user interface accessory (PC 041966). In this configuration, REMOTE1
controls the level of output one and the source selection for both outputs. REMOTE 2 controls the level
for output two. The A/B pin from REMOTE 1 needs to be jumpered with wire to the A/B pin on REMOTE2.
This configuration requires setting the REMOTE 1 CONTROL DIP switch to ZONE 1 and the A/B SELECT
DIP switch to REMOTE. If the A/B jumper wire is not connected, output two will default to amplifying
input B constantly. If output two is to amplify input A constantly, the A/B pin of REMOTE 2 needs to be
jumpered to the COM pin. This configuration also works with the remote types reversed with a volume
control user interface accessory (PC 041966) on REMOTE 1 and a volume control with A/B switch user
interface accessory (PC 041967) on REMOTE 2.

Loudspeaker Usage
This table shows the maximum quantity of loudspeakers supported by each IZA 2120-HZ or ZA 2120-HZA
amplifier output for each loudspeaker tap setting. The data is based on the maximum output of 120 watts
per each amplifier output. Do not exceed 120 W per output.
High-impedance loudspeakers per amplifier output
Max. Qty. of Loudspeakers Per Output / Tap Setting
The FreeSpace® zone amplifier makes system expansion easy. When a system design requires more
loudspeakers than the FreeSpace IZA 2120-LZ/HZ integrated zone amplifier can support, a FreeSpace
zone amplifier can be connected to provide additional power or zones.
When connected together, the IZA 2120-LZ/HZ and any zone amplifier (ZA 2120-LZA/HZA, ZA 250-LZ,
ZA 190-HZ) can operate together as one system, sharing the same music and paging sources. The IZA
2120-LZ/HZ amplifier operates as the master of the zone amplifier, determining which audio sources will
be heard. The overall MASTER LEVEL volume can be controlled by the integrated zone amplifier in one
larger zone, or volume control can be distributed in multi-zone installations.
Connecting an IZA 2120-LZ/HZ Amplifier to a ZA 2120-LZA/HZA Amplifier
Using the included RCA cable, connect the AUX OUT of the IZA 2120-LZ/HZ amplifier to the unbalanced
INPUT of any zone amplifier.

Note: It is recommended that when amplifiers are connected together, that both amplifier AC power cords
are plugged into the same AC outlet to reduce potential noise issues.
Line Input Connections
When using a front-end signal processor, or connecting multiple zone amplifiers to an integrated zone
amplifier, the included RCA cable may need to be modified. The wiring diagram for the zone amplifier

Troubleshooting
ProblemWhat to do
• No power• Turn on power. Blue LED on front-panel will be visible when power is on.
• Make sure the power cord is plugged in.
• Try a dierent AC outlet that is working with another piece of equipment.
• Power is on, but no
sound
• Power is on, but sound
is low
• Sound is distorted• Verify that the INPUT SIGNAL CLIP LED on the front-panel is not red. If it is red, reduce the source
• Unnatural sound• Verify that the proper EQ preset is selected for the loudspeakers being used. With the IZA 2120-
• Make sure the input source is turned on.
• Verify that there is an input signal from the source.
• Check the cable connections from the source to the amplifier.
• Ensure the desired source (A/B) is selected on the front panel.
• If a user interface is connected to the REMOTE connector on the rear panel, make sure the desired
source (A/B) is selected on user interface (user interface overrides the front-panel source select).
• Make sure the MASTER LEVEL control is turned up.
• If a user interface is connected to the REMOTE connector on the rear panel, make sure the volume
control on the user interface is turned up (user interface overrides the front-panel MASTER LEVEL
control).
• Make sure a 1/8” (3.5 mm) TRS input cable is not connected to the AUX INPUT.
• The AUX INPUT has a mechanical override feature so if an input cable is connected to it the
selected Input A/B source will be automatically overridden - even if the AUX INPUT audio source is
not playing or connected.
• If a contact closure is connected to the MUTE connector on the rear panel, check the switch to
ensure the mute function has not been triggered.
• If a source is connected to the PAGE INPUT connector on the rear panel, make sure it has not been
triggered.
• Make sure loudspeakers are connected properly.
• Make sure that loudspeaker taps are set correctly. See “Loudspeaker Usage” on page 33.
• Check that the amplifier has adequate ventilation. Improper ventilation could cause the amplifier to
go into protection mode and no audio will be heard.
• Ensure that the output wiring is correct. A short circuit will cause the amplifier to go into
protection mode and no audio will be heard.
• Verify that the audio input source output is turned up to a nominal level.
• Check the cable connections from the source to the amplifier.
• Increase input level of source with GAIN controls on amplifier. Turn GAIN knob clockwise until you
start seeing a red INPUT SIGNAL CLIP LED on front-panel. Then turn GAIN counter-clockwise until
the LED turns green.
• Make sure OUTPUT TRIM controls on amplifier are not turned down too low.
• If a user interface is connected to the REMOTE connector on the rear panel, make sure the volume
control on the user interface is turned up (user interface overrides the front-panel MASTER LEVEL
control).
• Make sure that loudspeaker taps are set correctly. See “Loudspeaker Usage” on page 33.
output level or reduce the input gain.
• If the input source signal is clean, verify that the loudspeakers are not overdriven or damaged.
Check the loudspeaker tap setting.
HZ, use the HPF setting for loudspeakers other than FreeSpace® loudspeakers and those that have
their own EQ settings.
• Check the TREBLE and BASS controls on the front-panels.
