The long years of experience at the top level of broadcasting technologies, as well as the undisputable expertise of our engineering team have brought forth a brand new audio processing tool – the DB6400 FM and Digital Radio 4-Band Audio Processor.
The much-anticipated DB6400 is an innovative tool with an ultra low latency DSP-based design for unrivalled quality of sound. It has a built-in IP Audio Player which supports MP3 and PCM audio formats, as well as a fully dynamic RDS/RBDS encoder. Solves the dead-air problem by switching over to a backup source and sending an email notification.
The DSP-based Stereo Encoder in DB6400 guarantees precision of the MPX signal with advanced peak control and two independently-configurable composite MPX outputs. The DB6400 offers perfect audio clarity no matter what the source material is. A complete processing architecture: Wide band AGC with “Intelligent Gating”, 4-band Parametric EQ, Advanced Bass and Treble Controls, 4-Band High Quality Sound processor with Fidelity control and Sound Impact, 4-Band Limiter, FM Limiter with advanced distortion & pre-emphasis control and HD Lookahead Limiter.

Another feature that distinguishes the DB6400 from other products of its category is its Fallback function. This cutting-edge device is able to detect signal loss. In the case of silence at the main audio input, it automatically switches over to a backup source, thus ensuring a constant audio feed. What is more, an email notification is immediately sent which allows for an instant response on the part of your technical support team. Through the use of a standard FTP client, you have the opportunity to update the backup content at will via any PC. An additional asset is the automatic return to the main audio source as soon as the default input is restored. All silence sense parameters are user-defined.
Needless to say, the DB6400 comes with a user-friendly, comprehensive and well-organized user interface. Access is available through the front panel, remotely via TCP/IP and by using the WEB interface through iOS, Android or any other mobile device.
This one-of-a-kind device is the peak of DEVA’s engineering achievements combining simplicity of use, affordability of price and top performance and employing an array of technical parameters not found in any other device of its class.
