dB-NET series Digital DSP Audio Seamless Matrix Switcher
The dB-NET series digital audio processor is a freely designed
audio processing and control system. It uses advanced DSP
processing technology, with a new automatic mixing, feedback
elimination algorithm, targeted to solve the application of the
various practical problems in the scene. Because most of the
control through the software operation, so the appearance can be
more concise and lively. The operator simply click the next mouse,
no longer as in the past, in the field to adjust the complex
large-scale mixer to complete the function conversion, greatly
simplifying the operational difficulty.
The processor family is a family of complex audio signals that use
a built-in DSP chip that uses a standard 48KHz / 24bit (up to
192KHz / 32bit) high quality A / D and D / A converter for
multi-channel analog Signal and digital signal interchange, the use
of industry-leading Texas Instruments TI core processing chip
(450MHz Flops), the balance, delay, matrix mixing and other
conventional functions at ease, more built-in efficient audio
algorithm, the main solution to the whistle, echo , Noise and other
applications in the difficult problems.
Main Features
1. 4,8,12,16 CH balanced microphone input, using the phoenix plug
interface
2.4,8,12,16 CH balanced microphone output, using the phoenix plug
interface
3. The front panel support a variety of audio formats to play and
can extend the USB multimedia storage for recording.
4.Support PC, mobile phone, tablet, web, key panel, Control system
and so on to control
5. Main algorithms, such as built-in signal generator, auto mixing,
feedback suppressor, echo cancellation, noise
cancellation(Optional) etc.
6.Input per channel: preamplifier, signal
generator,expander,compressor,5 parameters of equilibrium.
7.Output per channel: 31 segment graphic equalization, delay,
divider, limiter
