Bose FreeSpace ZA 2120-HZA

Bose FreeSpace ZA 2120-HZA zone amplifier (Product Code 791355-1410)

Bose FreeSpace ZA 2120-HZA zone amplifier is designed to provide basic amplification and sound system expansion when using front-end Bose products such as FreeSpace® integrated zone amplifiers and ControlSpace® engineered sound processors. With the inclusion of AmpLink, up to 8 digital audio channels can be sent to the amp from a Bose DSP via a shielded CAT 5 cable.

Reliable 2 x 120 W Class-D amplification optimized for 70/100V high-impedance applications

AmpLink transports up to 8 uncompressed, near zero latency, digital audio channels between Bose DSPs and the ZA 2120-HZA via shielded CAT 5 cable. The amp also supports a THRU path for daisy-chaining digital audio to other Bose AmpLink products at a distance of up to 10 m between products

Dual Remotes support optional volume adjustment for -independent, or combined, zone control which eliminates the need for bulky, -inefficient, and sound-altering 70/100V in-line volume controls

Expansion-ready connectivity with FreeSpace® IZA amplifiers and ControlSpace® engineered sound processors when additional sources and loudspeaker processing is required

Intuitive feature setup enables the amplifier to be configured without a PC for remote, input, output and automatic standby options

Auto-Standby feature allows the amplifier to consume less power when not in use

Remote muting allows the amplifier to be muted via a centralized control system

Applications

  • Retail stores
  • Restaurants and bars
  • Hospitality venues
  • Conference centers
  • Schools
  • Auxiliary zones

Architects’ and Engineers’ Specifications

The amplifier shall employ Class-D amplification topology. The amplifier shall incorporate a switch-mode power supply allowing normal operation from AC outlets ranging from 100 – 240 V (±10%) at 50/60 Hz. The amplifier shall have an IEC 320-C14 electrical power inlet and shall be equipped with a removable power supply cord. A power switch shall be located on the front panel. The product shall include protection from shorted loads and general overheating. The amplifier’s physical size shall be 1 RU in height by 1 RU in width and be capable of rack mounting. The product shall have venting with a single fan, continuous left-to-right airflow. Each output channel shall have output trim controls.

The amplifier shall have two output channels with a frequency response of 55 Hz to 20 kHz (+0/–3 dB) and drive 70/100V distributed audio systems. The amplifier shall have THD+N at rated power less than or equal to 0.3%. Output connections shall be made via 2-pin touch-proof Euroblock connectors.

The amplifier shall meet or exceed the following performance specifications: channel separation (crosstalk) less than or equal to –58 dB below rated power at 1 kHz and dynamic range of 88 dB. The amplifier shall have 1 line-level input (RCA stereo or 5-pin Euroblock), one AmpLink digital audio input (RJ-45), one AmpLink digital audio thru connection (RJ-45), and 1 remote control input (RJ-45). Three LEDs shall be visible on the front panel – one (blue) for power/standby indication, the second (red) for input level over 11 dBV, and the third (red) for output level over –2 dBFS.

The amplifier shall have a 2 remote control inputs intended for use with the Bose Volume control user interface or third party 10k ohm linear taper potentiometers. The amplifier shall offer a master mute connection for use with external dry contacts to mute output of the amplifier. The rear panel shall contain a dual/summed input switch that allows optimization of the amplifier output.

The amplifier chassis shall be constructed of painted steel. The dimensions of the amplifier shall allow for 19-inch (483 mm) EIA standard rack mounting. The chassis shall be 1.7 inches (44 mm) in height, 19.0 inches (483 mm) in width and 12.8 inches (324 mm) in depth. The amplifier chassis shall weigh 8.5 pounds (3.9 kg). The amplifier shall be the Bose FreeSpace ZA 2120-HZA zone amplifier.
