Digital Audio Processor D6575

Name: Digital Audio Processor
Brand: 2026 Guangzhou DSPPA Audio Co., Ltd.

● Digital audio processor with 96KHz sampling frequency, 32-bit DSP processor, 24-bit A/D and D/A converter.

● With 4 audio signal inputs, 3 groups of 5 mic inputs, standard 3.1, 4 or 5.1 channel output.

● With a USB interface to connect a PC, with remote control and infrared control.

● The function keys or thumb wheel on the panel or PC control software can be used directly for function settings, which is convenient, intuitive and simple.

● A single machine provides 20 groups of device data storage and 10 groups of effect data storage, which can be copied between devices through PC software.

● It can be locked by functions to realize data confidentiality, so as to prevent the operation of miscellaneous personnel from damaging the working state of the machine.

● Each output channel has a 7-band independent EQ (optional parameters, high key and low key), a high-pass filter and a low-pass filter. Both the high-pass filter and the low-pass filter have 1 slope and 3 different modes.

● Adopt Chinese character LCD screen and 6-segment LED to display accurate digital level meter, mute and editing status of the input/output channel.

● Each input and output has a delay, phase control and mute settings, with the input delay up to 30ms and the output delay up to 60 ms.

● The effect ratio, microphone volume, music volume and effect volume of the output channel can be controlled.

● The microphone has 4 levels of anti-howling function, and both the microphone and music signal have noise gates.

● The effect has 3-band parametric equalization and a pair of high-pass and low-pass filters, and the specific parameters of echo and effect are adjustable.

● The main parameters of the channel can be controlled by connecting the central control through the S terminal or USB interface.

● It can be connected to a PC via WIFI and can be remotely controlled via the Internet.

● With a resolution of ≥1279*790.
