Product and other characteristics
Dip-8710 full function professional decoder
Three groups of optical fiber / coaxial digital signals, two groups of analog signal audio input, two groups of HDMI digital to analog conversion, three channels of microphone input, 7.1 digital decoding independent output.
Support Dolby Digital, Dolby directional logic, DTS, HDMI next generation lpcm 7.1 channel decoding, multiple listening modes and playback of sound field effect.
Using agate large-scale FPGA as1e5f1ka as the central processing unit, built-in high-speed 8051 hard core, real-time processing PCM signal, so that the sound can get a higher degree of reduction; and using multiple dynamic memory chips, so that the data conversion speed is faster and more stable, with multiple groups of changeable data storage and call.
A number of 32 bit DSP logic digital processing chips are used as the core of the machine, and the over frequency four cores are respectively used to process the reverberation effect and reverberation effect of the vocal signal. The effect has two original modes of classic and delay to deal with echo and reverb, and can be used independently or in combination.
The music part has equal loudness adjustment, channel mode and 9-segment octave high-precision equalization processing. The microphone part has compression, lifting and 9-segment octave equalization processing.
The 7-speed automatic feedback suppression function of high reduction original DSP technology is superior to frequency shift and notch processing.
The humanized subwoofer auto attenuation function is controlled by the voice signal, and the starting point and recovery time can be set arbitrarily.
Full function remote control, panel button direct dialogue adjustment; professional and user-friendly PC control operation interface, which can be connected with PC through RS232 interface.
