Availability:
Special Order ItemThis item is not stocked and needs to be ordered from the manufacturer. Please contact our sales team for more information.
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 speaker or a 45 speaker. The gain range of the module is sufficient to accommodate this wide variety of source levels.-
Features:
- Intercom Electronics
- Intercom with Push-to-Talk
- Mic or Speaker Input
- 8 ohm or 45 ohm Speakers
- Bidirectional Communication Option
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.
| 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 source) -55 dBu (600 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) |
| Mute Switching Type: | Solid-State, no relay contacts used |
| Mute Release Delay: | 15 ms |
| Power Requirement: | GROUND-REFERENCED, 24 to 33 Vdc @ 175 mA |
| Ambient Operating Environment: | 0 degrees C to 50 degrees C |
