The ICA-202D provides a complete audio and logical interface for an integrated systems
solution. In most applications the Remote Speaker is accessed through a Switching Matrix,
controlled by a computer, or PLC.
The Operator microphone may be either a Dynamic, or Condenser type.
The Microphone is balanced and may be Phantom Powered.
If a flush mounted microphone is required, the Tech Works HM-1 is recommended
The Operator Speaker output is optimized for 100-Ohm voice coil speakers.
The Maximum Output is 25-Volts. Internally, the output is built out with a 66-Ohm resistance.
A 45-Ohm, 2.2-Watts voice coil or higher impedance is acceptable.
A 25-Volt speaker tapped at 5 watts or less is also acceptable.
