What are the front-panel controls and indicators of the FreeSpace® IZA integrated zone amplifiers?

  • 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 -39 dBV to 9 dBV, LED goes red over 9 dBV.
  • OUTPUT LIMIT LED – LED is green from -46 dBFS to -2 dBFS, LED goes red over -2 dBFS, approximately 80 W/channel.
  • AUX INPUT – 1/8" (3.5 mm) stereo line-level input connector. Connection mutes INPUT A and INPUT B for priority override when the AUX INPUT DIP switch is set to “Enabled.”
  • INPUT A/B Switch – Allows selection of rear line-input channels A or B.
  • TREBLE/BASS Knobs – Provides +/-6 dB adjustment at 7 kHz and 100 Hz.
        - IZA 2120-LZ: One set of knobs, allows tonal adjustments of both outputs simultaneously.

The IZA amplifier is appropriate for use in many applications including retail stores, restaurants and bars, hospitality venues, conference rooms, schools and auxiliary zones for large sound systems.

How can the IZA 2120-LZ amplifier be configured using the DIP switches?

  • Rear panel DIP switches offer flexible operation modes:
    OUTPUT – The outputs can either be set to stereo or mono mode.
  • A/B SELECT – Master A/B selection can either be front panel controlled or remote controlled.
  • AUTO STANDBY – If enabled the amplifier will go into auto standby mode after twenty minutes without an input signal.
  • PAGE BYPASS MASTER – The paging volume can either be set to the master volume or be set at its own independent volume with the rear panel knob.
  • PAGE MODE – Paging can either mix with the selected input source or duck the input source when activated.
  • PAGE START – Paging can be activated on either a PTT stimulus or a VOX stimulus.
  • AUX OUTPUT – The auxiliary output can either have a flat output (without EQ) or with an EQ set from the EQ slide switch.
  • AUX OUTPUT – The auxiliary output level can either follow the master level when switched to variable, or it can be set to maximum level when switched to fixed.
  • AUX INPUT – The auxiliary input can either be enabled or disabled. If the auxiliary input is enabled a connection made to the auxiliary input will mute all other inputs.

How can the IZA 2120-HZ amplifier be configured using the DIP switches?

Rear panel DIP switches offer flexible operation modes:

  • REMOTE 1 CONTROL – Remote one can be set to control both outputs (zones) simultaneously or each output (zone) can be controlled via its own remote. Each remote has independent A/B selection capability.
  • A/B SELECT – Master A/B selection can either be front panel controlled or remote controlled.
  • AUTO STANDBY – If enabled the amplifier will go into auto standby mode after twenty minutes without an input signal. The feature can be enabled (ON) or disabled (OFF) by a DIP switch.
  • PAGE OUTPUT – Paging can be set to occur in zone one only or both zones.
  • PAGE BYPASS MASTER – The paging volume can either be set to the master volume or be set at its own independent volume with the rear panel knob.
  • PAGE MODE – Paging can either mix with the selected input source or duck the input source when activated.
  • PAGE START – Paging can be activated on either a PTT stimulus or a VOX stimulus.
  • AUX OUTPUT 1 – Auxiliary output 1 (white) can either have a flat output (without EQ) or with an EQ set from the EQ 1 slide switch.
  • AUX OUTPUT 2 – Auxiliary output 2 (red) can either have a flat output (without EQ) or with an EQ set from the EQ 2 slide switch.
  • AUX OUTPUT – The auxiliary output level can either follow the master level when switched to variable, or it can be set to maximum level when switched to fixed.
  • AUX INPUT – The auxiliary input source can either be output into zone one only or both zones.
  • AUX INPUT – The auxiliary input can either be enabled or disabled. If the auxiliary input is enabled a connection made to the auxiliary input will mute all other inputs.
  • OUTPUT VOLTAGE – The output voltage can either be set to 70V or 100V.

What is Bose® Dynamic Equalization (EQ)?

Bose Dynamic EQ is a DSP function that ensures full and balanced music at any volume level.
 

What is Bose® Opti-voice® paging?

Opti-voice® paging is a DSP function that equalizes the vocal frequency range for clear speech intelligibility while providing seamless transitions.

Is a computer required for set up?

No. All set up is done locally from the front and rear panels.
 

Can I expand an IZA system with a ZA amplifier?

Yes. The Bose® FreeSpace® ZA 2120-LZ / ZA 2120-HZ zone amplifier makes system expansion easy. When a system design requires more loudspeakers than the FreeSpace IZA 2120-LZ / IZA 2120-HZ integrated zone amplifier can support, a FreeSpace ZA can be used to provide additional channels.

What types of protection are available in the amplifier?

The amplifiers are fully protected against loudspeaker output shorts, high temperature damage, and excessively low or high AC line voltage conditions. The IZA 2120-HZ also has an integrated 55 Hz high pass filter to avoid potential transformer saturation.
 

Is the FreeSpace® IZA zone amplifier weather rated?

No. This product must be used indoors. It is neither designed nor tested for use outdoors, in recreational vehicles or on boats.
 

Does the IZA 2120-LZ / IZA 2120-HZ microphone input support condenser microphones?

The IZA amplifiers do not supply phantom power for use with condenser microphones. The IZA 2120-LZ / IZA 2120-HZ will support low impedance signals from dynamic microphones.
