- Main Features:
- EAS alert insertion for up to three stations. Insertion can occur simultaneously on one or more station outputs, but alerts can not be overlapped
- Front panel test switches (recessed), jumper defeatable.
- Encoder audio input switchable between balanced analog feeding the ADC or AES digital input.
- Built-in 24-bit analog to digital converter (ADC) configurable via DIP switches for sample rates of 44.1 or 48kHz, or external wordclock.
- Multi-turn front panel level adjustment trimmer for ADC encoder audio input.
- Dedicated fourth AES output provides encoder audio for additional devices on a terminal block connector.
- Transparent signal switching via sealed mechanical relays utilizing 2-form-C bifurcated–crossbar silver alloy contacts with gold overlay.
- RJ45 station audio input and output jacks simplify wiring and service.
- SPST status relay outputs with LED indicators.
- Remote control via RS-232 serial and TCP/UDP Ethernet commands or contact closure inputs.
- Dip-switch selectable unit ID.
- Removable euroblock-style screw terminal connectors for status relays and contact closure inputs.
