Radio Design Labs ST-IC1
Intercom Amplifier

OUR PART #  STIC1


Radio Design Labs' ST-IC1 is part of the group of versatile STICK-ON products from Radio Design Labs. STICK ONs feature the advanced circuitry for which RDL® products are known, combined with unequalled versatility in mounting possibilities. The durable adhesives provided with the ST-IC1 permit permanent or removable mounting. Numerous available mounting accessories, brackets and rack-mount chassis’ are optionally available to facilitate any system design.

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.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

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 ohm speaker or a 45 ohm 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 ohm load. The output circuit can be connected to any load impedance of 4 ohm or greater.

When no connections are made to either MUTE terminal, the module output is active. If the MUTE - terminal is pulled to ground (using a switch, an open-collector transistor, or the slave terminal of another RDL module), the ST-IC1 output will mute. Pulling the MUTE + terminal high (+15 Vdc) has the same effect. In a bidirectional intercom, the MUTE - terminal of the master module is connected to the MUTE + terminal of a secondary module, thereby muting the secondary module. When the master module’s MUTE - terminal is pulled to ground, the master modules mutes and the secondary module becomes active. There is an internal 15 ms time delay between the two operations which is fast enough to have no audible effect on voice communication, but prevents any feedback effects during switching.

Wherever an intercom is needed, the ST-IC1 is the ideal choice. Use the ST-IC1 combined with other RDL RACK-UP, STICK-ON, or TX™ series products as part of a complete audio/video system.
