Product Description

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

Frequency Response:300 Hz to 4 kHz (+/- 2 dB, filtered for voice band intelligibility)
Gain:Off to 70 dB (adjustable)
Input level for 1 W RMS output:-60 dBu (8 Ω source); -55 dBu (600 Ω source)
THD+N:< 1% (1 kHz, referred to 1 W @ 50 dB gain)
Residual Noise (below 1 W):< 75 dB (60 dB gain setting, unmuted)
Operating Output Power:1 W RMS
Maximum Output Power:1.5 W RMS (before clipping)
Mute Attenuation:> 115 dB (1 kHz)
