TOA A-1812 2 Zone Mixer Amplifier

Two zone mixer amp. 120 watts, 100 volt line / low impedance 4-16Ω.

List price Ex. VAT: £430.54

Details

The TOA A-1812 two zone mixer amp is rated at 120 watts, 100 volt line.

There are 3 mic inputs and 3 line inputs as well as telephone and emergency equipment inputs. A chime function assists paging operations and there is a selectable input priority feature.

Switchable phantom power is available for microphones.

In addition, a line output is provided in order to increase the power amplification by adding a power amp such as the P-1812.

Can be powered by 240v mains or 24V DC.

Rack mountable using optional brackets - see MB-25B.

  • Power output of 120 W
  • Built-in chime unit (1-tone chime, 2-tone chime, and ascending 4-tone chime)
  • Chime can be sounded on use of the MIC 1 input (an optional PM-660D Paging Microphone connectable) or on Telephone paging.
  • Priority function provided for inputs as follows: Emergency input has the highest priority to all inputs. (Contact activation) Telephone Paging input has precedence over the inputs other than Emergency input. MIC 1 input has precedence over the inputs other than Emergency and Telephone Paging inputs.
  • Emergency function performs as follows: Closing the contact at the Emergency Control input terminals turns ON the unit's power even if it is OFF, and both Zone selector switches.
  • Following audio signal inputs suitable for the intended applications: 3 Microphone inputs, 3 AUX inputs, 1 Emergency input, and 1 Telephone Paging input.
  • Phantom-powered Microphone inputs (power ON/OFF switchable).
  • Combined XLR/phone jack Microphone inputs for convenient use.
  • Electronically-balanced Microphone inputs.
  • Speaker selectors for 2-zone broadcast.
  • Tone controls (bass and treble).
  • Output level meter.
  • Master volume control for overall input (excluding the Emergency input) signal level adjustment.
  • AC and DC power source.
