DEVA Broadcast DB6400 – FM & Digital Radio 4-Band Processor

Fully DSP-based, top-quality 4-Band Audio Processor

The long years of experience at the top level of broadcasting technologies, as well as the indisputable expertise of our engineering team, brought forth a brand new audio processing tool. We showcased the DB6400 FM and Digital Radio 4-Band Audio Processor.

The User Interface

Nevertheless, the DSP-based Stereo Encoder guarantees the precision of the MPX signal with advanced peak control. And also, there are two independently-configurable composite MPX outputs.

The DEVA Broadcast DB6400 offers perfect audio clarity no matter what the source material is. It is a complete processing architecture: Wide band AGC with “Intelligent Gating”, 4-band Parametric EQ, Bass FX, Treble FX, 4-Band HQ-Sound dynamic processor with Fidelity control and Sound Impact.

It also includes 4-Band Limiter, FM Limiter with advanced distortion pre-emphasis control and HD Lookahead Limiter.

Another feature that distinguishes the DEVA Broadcast DB6400 from other products in its category is its Fallback function. The 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.

There is always a constant audio feed. What is more? It sends an email notification immediately which allows for an instant response on the part of your technical support team.

Through the use of a standard FTP client, it leaves an opportunity to update the backup content at will via any PC. Moreover, the automatic return to the main audio source as soon as the default input is restored is an additional asset. Yet, all silence sense parameters are user-defined.

Needless to say, the DEVA Broadcast DB6400 comes with a user-friendly, comprehensive and well-organized user interface. The front panel provide access is remote via TCP/IP and by using the WEB interface through iOS, Android or any other mobile device.

Furthermore, it is a one-of-a-kind device. In addition, it is the peak of DEVA’s engineering achievements. It combines the simplicity of use, affordability of price and top performance. It does all these by employing an array of technical parameters which you can rarely find in any other device of its class.
