Description

Output decoding with two DAC, CS4398 and PCM1798, more choices and better cost performance.

The latest FIR customized version can additionally add a control panel, so as to separate from the computer and use the local display for local debugging, add volume knob and mute control, use a new interface on the PC side, and add DEQ dynamic equalizer and FIR filter, delay 50ms The internal precision is 0.01ms, the minimum high-pass filter setting is 10hz, and the sampling rate can be switched to 96/192k.

Added AES/spdif coaxial to I2S interface board, which can replace ADC directly, and supports sampling rate up to 192KHz;

The configured ADC board has been upgraded to PCM4202

The backboard is compatible with the new FIR version, without SPDIF interface, but you can buy our AES receiving board to support AES or SPPDIF

Product:

Size:187*92*33mm

Debug your own program, and then the tools we provide are solidified into the MCU through the USB interface on the board, and you can run away from the computer.

The system framework defaults to 96K or 192K sampling, 4 in 8 out I2S interface plus 4 in 8 out SPDIF interface, professional audio, HIFI device, personal DIY

DSP2148X development kit (with supporting PC software, can be used directly as audio processor / dsp electronic crossover)

ADSP21489 floating-point core processor + PCM1804 (ADC) + PCM1798 (DAC), delay / frequency division / phase / compression / mixing / GEQ / PEQ, system joint tuning, storage / recall, Chinese and English interface switching, direct computer USB It doesn’t need secondary development. It has 4 input and 8 output professional audio processors, which can be used directly as DSP electronic crossover.

PC interface: Support Chinese and English switching, USB direct connection and driver-free.

ADSP21489 core board

USB interface can update firmware or program firmware. The debugging interface can use any of the USBI emulators in this shop. It provides basic framework routines, and other functional algorithms can be added arbitrarily. For example, if you want to do something abnormal such as a 500-segment EQ

ADC board (PCM1804 + MC33078)

You can change the op amp yourself or replace it with the more powerful PCM4202

DAC board (PCM1798 + MC33078)

You can change the op amp yourself or replace it with the more powerful PCM1794

Analog IN A/B is shared with S/PDIF,The default is S/PDIF digital input, switch to switch coaxial or optical fiber

4 in 8 out package (one ADC analog input + 4 DAC analog output + core board + test bottom board)

Both ADC and DAC boards are balanced circuits, and there are 3P pin holes on the boards. Of course, our backplane is only connected to the positive terminal of the signal input/output.

In order to better experience our products, the core board is not recommended to be purchased separately, because the adverse consequences caused by connection or power problems are not easy to define, so we do not accept returns for DSP chip damage.

We also have USBI emulator for ADI full range of DSP, SPI / 12C two communication methods, the function is fully compatible with the official version.

Switching power supply that can be used together. (Set with power input and output interface cable)

Switching power supply board, suitable for professional or civilian electronic products such as pre-effects / audio processors

The output voltage of this switching power supply is: (no load)

-12V terminal actual voltage -19V 1A maximum load current

+ 12V terminal actual voltage + 19V 1A maximum load current

A + 5V / D + 5V terminal The actual voltage 6.8V (regulated voltage) defaults to 2A, the maximum output can reach 4A

3V0 terminal The actual voltage is 3V, which can be discharged quickly as the shock protection voltage of the switch

If you need 5V output (+ -19v becomes about 14V, please ignore the label on the board), you need to inform the customer service to modify or modify it yourself
