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 (A-

weighted).

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

DXA 2120 digital mixer/

amplifier.

Safety and Regulatory

Compliance

The 120V/220-240V AC variant (PC 040753, PC 040754,

PC 040755, PC 040756) of the FreeSpace DXA 2120

digital mixer/amplifier complies with CE requirements, is

UL Listed according to UL60065 (7th edition) and CAN/

CSA C22.2 No. 60065-03; CB approved, according to

IEC60065 (7th edition), including group and national

differences; GS approved, according to EN60065 (7th

edition). It also complies with FCC Part 15B Class A (2003),

EN55103-1 (1997), EN55103-2 (1996), and CISPR13 (2003)

requirements. The 100V variant (PC 040742) of the DXA

2120 digital mixer/amplifier is PSE compliant.

Additional Notes

Amplifier Power

A single channel is driven to full power with the nominal load

impedance (120W / 4, 100W / 70V / 49, 100W / 100V / 98).

Output power is measured using a 1 kHz sine wave with a

THD of less than 0.5%, as measured at the amplifier output.

Dynamic Range

The output of the amplifier is connected to the rated load

impedance, and the input and output gains are set to

maximum. A dB-calibrated voltmeter is connected to

the amplifier’s output through an A-weighting filter (in

accordance with IEC 60651). A 1 kHz signal is connected

to one of the line inputs, and the level is adjusted to achieve

the amplifier’s rated output power. The voltmeter is then

zero-referenced. The signal source is removed, and the line

input is shorted. The dB-calibrated voltmeter now reads the

absolute dynamic range of the system.
