A-2060/2120/2240 Mixer Power Amplifiers
The mixer power amplifier shall be ideal for a wide variety of
installed sound applications such as paging and background
music (BGM) distribution.
The amplifier shall control and mix up to two balanced (screw
terminal) MIC inputs, a balanced (screw terminal) TEL input and
two unbalanced (RCA pin jack) AUX inputs, and deliver an audio
output of 60W / 120W / 240W. The MIC input impedance shall be
600 ohms and the TEL input impedance shall be 10k ohms. The
AUX impedance shall be 10k ohms. Frequency response shall be
50 to 20k Hz (+/- 3 dB) with less than 1 % THD at 1/3 rated
output. It shall be capable of operation from a 120 V AC 60 Hz
line. The S/N ratio shall be over 60dB.
The mixer power amplifier shall include 25 V, 70 V or 4 ohm
transformer-isolated outputs with screw terminal type connections
and protective cover plate, and AUX output with dual-RCA jacks
for recording or connection to an external booster amplifier. The
amplifier shall incorporate an auto-mute function that overrides
the BGM channels (AUX 1 and AUX 2), for voice-activated paging
at an adjustable threshold level (0 to 64dB for MIC 1 and MIC 2/0
to -23dB for TEL). The mixer power amplifier front panel shall
include a master volume control, MIC/TEL and AUX volume
controls, Bass/Treble tone controls (100 and 10k Hz, + 10 dB)
and Signal, Peak and Power LEDs. Fan cooling ventilation shall
be provided (A-2240 only).
Dimensions shall be A-2060: 420(W) × 100.9 (H) × 280.3 (D)
(16.5” × 4.0” × 11.0”), A-2120/2240: 420(W) × 100.9 (H) × 360.3
(D) (16.5” × 4.0” × 14.2”). Net weight shall be A-2060: 7kg
(15.43lb), A-2120: 10.8kg (23.81lb), A-2240: 13.2kg (29.10lb).
Front panel finish and material shall be black ABS resin and case
finish (and material) shall be black steel plate.
The mixer power amplifier shall be TOA model A-2060/
A-2120/2240.
