Integrated Zone Amplier
Architects’ and Engineers’ Specications
The mixer/amplier shall employ Class-D amplication together
with a digital signal processing architecture running at 48 kHz /
24 bit. The mixer/amplier shall incorporate a switch-mode power
supply allowing normal operation from AC outlets ranging from
100 – 240 V (±10%) at 50/60 Hz. The amplier 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 mixer/amplier’s physical
size shall be 1 RU in height by 1 RU in width and be capable of
rack mounting using an included accessory kit. The product shall
have venting with a single fan, continuous left-to-right airow.
Each output channel shall have output trim controls.
The mixer/amplier shall have two output channels with a fre-
quency response of 20 Hz to 20 kHz (+0/–3 dB) and drive 4 ohm
loads at 120 watts per channel or 60 watts per channel into 8
ohm loads. The mixer/amplier shall have THD+N at rated power
less than or equal to 0.5%. Output connections shall be made via
two 2-pin touch-proof Euroblock connectors.
The mixer/amplier shall meet or exceed the following
performance specications: channel separation (crosstalk) less
than or equal to –60 dB below rated power at 1 kHz and dynamic
range of 88 dB. The mixer/amplier shall incorporate 3 line-level
inputs (two RCA stereo, one 3.5 mm stereo) and one microphone
input for paging applications. Two of the line level inputs shall
be selectable via a switch on the front panel while the third input
shall override line-input channels upon connection. The nominal
input sensitivity shall be 0 dBV for line level inputs and –40 dBV
for microphone inputs. The microphone input shall be mounted
on the rear, support dynamic microphones and select telephone
systems with PTT switching. The microphone input shall bypass
master volume control via a selector on the rear panel. All inputs
shall have individual input gain controls with the exception of the
3.5 mm priority input connector on the front panel. Three LEDs
shall be visible on the front panel – one (blue) for power/standby
indication, the second (red) for input level over 9 dBV, and the
third (red) for output level over –2 dBFS. The mixer/amplier shall
have an auxiliary line-output via two RCA connectors. The digital
signal processor shall enable a user-selectable loudspeaker
preset (Flat, Bose

and (via selector) the auxiliary output connectors. The front panel
shall also have user-accessible treble, bass and master volume
controls. The mixer/amplier shall have a remote control input in-
tended for use with the Bose Volume control with A/B switch user
interface or third party switches/10k ohm linear taper potentiom-
eters. The mixer/ amplier shall offer a master mute connection
for use with external dry contacts to mute output of the amplier
and auxiliary output. The rear panel shall contain a stereo/mono
switch that allows optimization of the amplier output and the
auxiliary line-level output when using stereo or mono sources.
The mixer/amplier chassis shall be constructed of
painted steel. The dimensions of the mixer/amplier
shall allow for 19-inch (483 mm) EIA standard rack
mounting. The mixer/amplier 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 mixer/amplier shall
weigh 9.0 pounds (4.1 kg). The mixer/amplier shall
be the Bose FreeSpace IZA 2120-LZ integrated zone
amplier.
