DB8009-MPX

MPX & Audio Silence Monitor with Advanced Backup Capabilities

The most flexible silence detector with uncompromising backup functionality

DB8009-MPX guarantees highly dependable monitoring of the Composite Stereo signal, Analog and Digital Audio feed and in case of signal loss automatically switches over to a backup source. The most notable advantage of this product, however, are the MPX inputs and outputs providing reliable MPX backup capability. In addition to that, it also offers built-in MP3 and IP Audio backup source options and incorporates a fully DSP-based core. Another important feature is its capability for alert notifications which, in case radio silence is detected, can be generated via email, SNMP or analog opto-coupled outputs. The device provides UPnP for easy discovery in local networks, as well as digital volume control of all audio sources, and can be incorporated effortlessly into the setup of either a single station or large radio networks.

DEVA’s DB8009-MPX is an exceptional example of a top-notch silence detector that continues the company’s hugely successful range of broadcast tools but at the same time stands apart in terms of the functionalities it provides users with. It guarantees highly dependable monitoring of the Composite Stereo signal, Analog and Digital Audio feed and in case of signal loss automatically switches over to one of a number of available backup sources.

Crucially, however, the most notable advantage of this product are the MPX inputs and outputs providing precise MPX monitoring and backup capabilities. Similarly to other tools in this product line, the DB8009-MPX also offers the familiar MP3 and IP Audio backup options. Its design incorporates a fully DSP-based Stereo Encoder which provides an MPX signal at the output even if the backup source has been set as Analog, Digital or IP Audio.

The unit can be easily configured and monitored by users via SNMP, the WEB Interface, the front panel LCD display and the set of soft buttons. Another important feature is its capability for alert notifications which, in case radio silence is detected, can be generated via email, SNMP or analog opto-coupled outputs. As an addition, if power failure is detected, the MAIN Audio and MPX inputs will switch directly to the Audio and MPX outputs. Once the power is restored, the DB8009-MPX will resume its proper operation.

The DB8009-MPX provides UPnP for easy discovery in local networks, as well as digital volume control of all audio sources, and can be incorporated effortlessly into the setup of either a single station or large radio networks. Through a standard FTP client, MP3 backup files can be uploaded onto the device, which also has a 4GB storage capacity ensuring no repetition of audio tracks for over 24 hours of playback.

The DB8009-MPX is a model that combines the immaculate monitoring performance of DEVA’s products with the much-valued precision of the Analog, Digital Audio and MPX silence detection to deliver a constant, uninterrupted audio feed.
