Overview

The ST-IC1 is the ideal choice where an intercom system is to be installed, or where an amplifier is needed to bring a mic level up to a 1 W speaker level with optional muting capability.

The ST-IC1 has one input, one output and two muting control terminals.

The input accepts a dynamic mic, a condenser mic (a phantom supply input terminal is provided to power condenser mics), an 8 ? speaker or a 45 ? speaker. The gain range of the module is sufficient to accommodate this wide variety of source levels.

The output is ground-referenced, and drives more than 1 watt RMS into an 8 ? load. The output circuit can be connected to any load impedance of 4 ? or greater.

Features

  • Intercom Electronics
  • Intercom with Push-to-Talk
  • Mic or Speaker Input
  • 8 ? or 45 ? Speakers
  • Bidirectional Communication Option
