Supporting SigmaStudio Programming with Open-sourced Demo Program and HEX File

The preamp unit, equipped with the ADAU1701 DSP chip, offers support for SigmaStudio programming when connected with WONDOM ICP5. To enhance customer convenience, we have developed an open-sourced Demo program for easy operation. We highly recommend using this Demo program as a foundation for programming. In case of accidental programming errors, a HEX file is available to restore the unit to its factory settings. You can find the programming guide and demo program from us.

2-IN, 4-OUT with 2-way Digital Crossover

With the powerful ADAU1701 DSP at its core, this preamp unit offers a versatile 2-in, 4-out configuration. Designed with the needs of audio enthusiasts in mind, our unit is integrated with 2-way digital crossover, ensuring precise signal distribution. To cater to a wide range of audio systems, we have carefully crafted the 4-out section, which consists of two channels (DAC0&DAC1, BANK A) dedicated to delivering exceptional bass reproduction, while the remaining two channels (DAC2&DAC3, BANK B) handle the mid-range signals. For seamless connectivity, we have equipped the rear panel with six RCA jacks, making audio input and output hassle-free.

Potentiometers, Switches and LEDs for Convenient Control and Monitoring

To enhance customer convenience, we have extended the GPIO ports of the ADAU1701 DSP to various interfaces. On the front panel, you will find four potentiometers that serve as high-pass/low-pass filters and volume controls. Additionally, two switches are provided for mute and phase control functions. The power and busy LEDs provide clear indications of the system's operational status. The adjustment range of the filter and the functionality of the interfaces can be modified through SigmaStudio. POT1 (MP3/ADC2) -----> High-pass Filter of Mid-range Output Channel, Default Adjustment Range: 3kHz-20kHz POT2 (MP8/ADC3) -----> Low-pass Filter of Bass Output Channel, Default Adjustment Range: 210Hz-3kHz POT3 (MP9/ADC0) -----> High-pass Filter of Bass Output Channel, Default Adjustment Range: 10Hz-310Hz POT4 (VOL) -----> Overall Volume Control
