CPF-01 MPX Program Fail Detector & Emergency Player

The B-Tech CPF-01 sets a new standard in FM broadcast program monitoring, combining intelligent source monitoring, automatic changeover, and emergency program playout in a compact 1RU unit.

The CPF-01 continuously monitors two independent MPX program paths, allowing broadcasters to maintain uninterrupted transmission.
MPX Input A serves as the primary program source, while MPX Input B provides an automatic backup should the primary source fail.

If both MPX sources are lost, the integrated USB MP3 player automatically takes over, providing emergency program audio until a valid source is restored.
Once normal operation resumes, the CPF-01 automatically returns to the selected program source after the configured delay.

Bright front-panel LED VU meters provide an instant visual indication of the audio levels for both monitored sources, while the LCD display clearly shows the current ON-AIR source and the selected headphone monitoring source.

With integrated GPO status outputs web interface with SNMP support, the CPF-01 can be easily monitored and controlled remotely, making it ideal for both studio installations and unattended transmitter sites.

Designed with reliability in mind, the unit features a passive fail-safe bypass.
In the event of a power supply failure, MPX Input A is automatically routed directly to the outputs, ensuring continued transmission.
