P-1812

P-1812 Booster Amplifier

  • When additional power amplification is required to power more speakers in a system, the TOA P-1812 Booster Amplifier can be connected to an A-1800 Series amplifier’s line out which provides an optimal level and impedance to efficiently drive the P-1812.
  • Switchable input levels
  • To interface properly with different equipment, input sensitivity can be switched between –10dB and 0dB.
  • Emergency control
  • On the back panel of amplifier is a remote-in terminal for emergency control which sets the default output level for the emergency input.
P-2240

P-2240 240 Watt Booster Amplifier

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.
