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.

POWER switch – ON/OFF AC power.



Power LED – Solid blue LED indicates the unit is ON. Blinking blue LED indicates the unit is in standby mode.



INPUT SIGNAL LED – LED is green from –37 dBu to 11 dBu, LED goes red over 11 dBu. MASTER LEVEL set at 5.



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.



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.



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.



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.



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 29 for more details.
