DEVA DB8000 – Silence Monitor & Backup Audio Player

Product Overview

The DEVA DB8000 is a dedicated silence monitor and backup audio player, designed to eliminate dreaded dead air in broadcast chains. In case of audio loss on the main program feed, the unit quickly detects silence and automatically switches to a secondary source or its built-in MP3 backup player. The core principle is simple but effective: continuous silence detection combined with instant, transparent switchover to keep listeners on-air. This makes the DB8000 ideal for both standalone stations and large radio networks that demand 24/7 reliability.

The DB8000 accepts professional balanced stereo analog program inputs on XLR connectors, with passive through audio switching to ensure signal integrity. When the main input fails, the device can switch first to the AUX input and, if that is also unavailable, to the built-in MP3 player with 2GB of internal memory, capable of more than 24 hours of non-repeating audio playback. Advanced bass and treble controls on the MP3 path allow engineers to fine-tune backup audio quality to match the on-air sound. A front-panel headphones jack provides convenient local monitoring of the active audio source.

For control and integration, the DB8000 offers a built-in DTMF decoder that can trigger source changes or start MP3 playback using predefined tone sequences, enabling regional content, local ads or emergency messages when needed. The unit also supports SNMP control and notification, an email client and an easy remote management interface for off-site supervision. Silence detection threshold and response time are fully adjustable, so switchover behavior can be tailored to each station’s operating style. Housed in a robust 19-inch 1U chassis, the DB8000 is engineered for simple installation and long-term continuous operation.

Frequently Asked Questions

• Q: What happens when the main audio input fails?
  A: When silence is detected on the main input, the DB8000 first switches to the AUX input or, if configured, directly to the built-in MP3 backup player, maintaining uninterrupted audio on-air.
• Q: How much backup audio can the DB8000 store?
  A: The internal MP3 player uses approximately 2GB of memory, providing over 24 hours of non-repeating backup audio playlists that can be updated easily from a computer.
• Q: Can the DB8000 be controlled remotely?
  A: Yes, the DB8000 supports SNMP control and notification, email alerts and DTMF remote control for source selection, allowing engineers to monitor status and manage source switching from remote locations.
