TOA A-3548D

The TOA A-3548D is a class D digital mixer amplifier with a 480 watt output and compatible with 100 volt line or low impedance systems (4 -16 ohms).

It is equipped with 3 MIC/LINE selectable inputs ( 2 with phantom power), 1 MIC input and 1 AUX input which can be also used for a music source.

The A3548D 2 channel speaker zone selectors (on high impedance only) make it ideal for sound systems in offices, shops, schools, restaurants and small production facilities.

Also ideal as a local amplifier integrated into a building wide voice alarm system. If an emergency signal is received, emergency messages will override the local sound and will be broadcast at the maximum level regardless of any localised volume settings.

Available in a range of power ratings - see related products if this isn't quite the power rating you need.

  • 5 Inputs: 1 Mic, 1 AUX, 3 MIC/AUX (selectable) , 2x Phantom power
  • 2 Zone speaker selector (high impedance only)
  • 2 Line out, 1 Rec out
  • 2 Zone control inputs / outputs
  • 1 Emergency output

 

Rack mountable with optional MB-25B brackets.
