FreeSpace® IZA 2120-HZ
The six-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 FS2C/SE/P, FS4CE/SE, and DesignMax
DM2C-LP/S, DM8C-SUB/FS3B. Since each output supports an independent EQ, the amplifier has the
ability to bi-amp by driving a loudspeaker with EQ on one channel and a sub with EQ on the second
channel, or any required combination.

q w e r t y u i
q POWER Switch - ON/OFF AC power.
w POWER LED - Solid blue LED indicates the unit is ON. Blinking blue LED indicates the unit is in standby
mode.
e INPUT SIGNAL LED - LED is green from –37 dBu to 11 dBu, LED goes red over 11 dBu. MASTER LEVEL
set at 5.
r OUTPUT LIMIT LED - LED is green from –46 dBFS to –2 dBFS, LED goes red over –2 dBFS,
approximately 80 W/channel. For each output, 120 watts is 0 dBFS.
t AUX INPUT - 1/8” (3.5 mm) stereo line-level input connector. A cable insertion mutes INPUT A and
INPUT B for priority override. Pages can still be made from the PAGE INPUT. The AUX INPUT is
summed to MONO. AUX INPUT does not have any gain adjustment, therefore, all gain adjustments
must be done from the external source device.
y INPUT A/B Switch - Selects either INPUT A or INPUT B on the rear panel when the rear panel A/B
SELECT DIP switch is set to FRONT.
u TREBLE/BASS Controls - Allows tonal adjustments of both outputs simultaneously. These are 1st order
shelving filters that provide a ±6 dB adjustment at 7 kHz and above (TREBLE) and 100 Hz and below
(BASS). They have a slope of approximately 6 dB/octave.
i MASTER LEVEL Control - Controls the overall system volume for both the loudspeakers and the AUX
OUTPUT when the AUX OUTPUT DIP switch is set to VARIABLE. If the AUX OUTPUT DIP switch is set
to FIXED, the AUX OUTPUT maintains maximum level.
Note: When using a REMOTE volume connection, the front panel MASTER LEVEL control becomes
disabled. See “Remote Control Connections” on page 26 for more details.
