The P-2240 offers a high performance-to-cost ratio, and can be used with
TOA’s A-2000 Series mixer power amplifiers. Because the P-2240 features
a 100V line input, it can be connected to the speaker line from another
amplifier. Also, the P-2240’s power can be switched on and off by remote
control, allowing it to be operated independently of the A-2000 Series.
A-2000 Series Mixer Power Amplifiers are designed to be highly cost- effective solutions to
the demands of PA applications. They offer high levels of performance and versatility and
are especially well-suited for broadcasting paging and supplying background music in
Schools, offices, shops, factories, mosques, churches and large meeting rooms.

A-2000 Series Mixer Power Amplifiers are designed to
be highly cost effective solutions to the demands of PA
applications. They offer high levels of performance and
versatility and are especially well-suited for broadcasting
paging and supplying background music in schools,offices,
shops, factories, mosques, churches, and large meeting
rooms.
The A-2000 series makes available a wide range of power
outputs (A-2030: 30W; A-2060: 60W; A-2120: 120W;
A-2240: 240W), with a frequency response of
50 – 20,000 Hz and distortion under 1%. Three balanced/
phone jack MIC inputs and two unbalanced/RCA pin jack
AUX inputs, along with high and low impedance balanced
(floating) speaker outputs and unbalanced REC outputs
ensure operational versatility.
Phantom power and muting are available on MIC 1, along
with tone control for bass and treble. Power, signal and
peak indicators are provided. In addition, the P-2240
Booster Amplifier offers a means of increasing power
amplification for system expansion through adding more
speakers.
• A full lineup of 2-unit size amplifiers offering a wide range
of power outputs from 30W to 240W.
• Scratch and fingerprint-resistant finish.
• Easy and quick volume control with master volume knob.
• Three electronically balanced microphone inputs, two
AUX inputs and recording output.
• Phantom power is provided to MIC 1, for supplying power
to a condenser microphone.
• Broad tone control adjustment range
