Bose FreeSpace DXA 2120

Bose FreeSpace DXA 2120 Digital Mixer/Amplifier (Product Code 040753)

The Bose FreeSpace DXA 2120 digital mixer/amplifier features a 6-in by 2-out design that provides signal processing, mixing, routing, paging and two-channel amplification for installed applications. It offers three versatile operating modes and is easily configured using the controls on the front panel. No external computer is required.

Six inputs: four mic/line inputs with choice of balanced Euroblock or unbalanced RCA connectors, one page input and one direct input

Two powered outputs that can operate at high or low impedance: 2 x 120 W at 4 ohms , 2 x 65 W at 8 ohms, or 2 x 100 W at 70/100V

Three operating modes for greater flexibility in installed music or speech applications: Mixer Mode, Dual Mono Select Mode, and Stereo Select Mode

Easy setup and control via onboard controls – no computer needed

DSP includes loudspeaker EQs and dynamic EQ functions engineered specifically for Bose loudspeakers

Opti-voice® paging provides a smooth transition between music and announcements

24-volt DC backup power connection for added reliability and integration onto fire and evacuation systems

Applications

  • Conference centers
  • Retail stores
  • Restaurants and bars
  • Hotels
  • Lobbies and conference rooms

Architects’ and Engineers’ Specifications

The unit shall be a digital mixer/amplifier. The unit shall use a digital signal processing architecture running at 44.1 kHz sample rate. The frequency response shall be from 40 Hz to 16 kHz (+0/-3 dB).

The dynamic range shall be 80 dB (typical) 40 Hz to 16 kHz. The signal-to-noise ratio shall be 75 dB or greater (Aweighted). The unit shall have mixing and routing capabilities as well as amplification.

The unit’s DSP shall feature selectable Bose® loudspeaker EQs as well as dynamic equalization. The input section shall have four mic/line inputs, one direct input and one page input.

The mic/line inputs shall have both 3-pin Euroblock connectors for balanced mic/line inputs and dual RCA jacks (summed to mono) for unbalanced line inputs. The direct and page inputs shall have 4-pin Euroblock connectors for balanced inputs. The page input shall be operated in PTT (push to talk) or Auto mode and provide automatic ducking for announcements.

The direct input shall automatically override all other inputs when a signal is detected for emergency signaling purposes. The output section shall feature two powered loudspeaker outputs with 5- terminal inverted Euroblock connectors.

The unit will have an auxiliary output with a 3-pin Euroblock connector. The amplifier section shall contain two powered outputs for high or low impedance: 2 x 120 watts at 4 ohms, 2 x 65 watts at 8 ohms, or 2 x 100 watts at 70/100 volts. The THD shall be less than 0.5 % @ full rated power.

The unit shall feature three different modes of operation: Mixer Mode, Stereo Select Mode and Dual Mono Select Mode. The 100V variant will operate at 100V AC. A second variant will be able to operate at 120 V/220 VAC-240 VAC; there will be an AC input voltage switch on the unit. The unit shall consume AC power of 40 watts or less at idle, 350 watts at maximum continuous rated power and also will have a 2-terminal barrier strip for connecting a 24 volts DC backup power supply.

The unit will have a remote input with a 6-pin Euroblock connector for using one or two volume controls and/or volume control with A/ B select user interfaces. The unit shall be configurable via the onboard controls and feature a “lockout” feature to prevent unwanted system changes. An RS-232 COM port will be available for system updates.

The unit shall be the Bose® FreeSpace® DXA 2120 digital mixer/ amplifier.
