Introducing our feature-rich DSP Preamp Unit built around the high-performance ADAU1701 DSP IC. Experience exceptional flexibility and playability with this meticulously designed device housed in a sleek and durable aluminum enclosure.

The preamp offers a versatile 2-in 4-out configuration with the default output set as a digital crossover. Connecting audio inputs and outputs is effortless thanks to the provided RCA jacks. To enhance user convenience we have incorporated General Purpose I/O ports (GPIOs) into external interfaces. These ports enable seamless operation and control through various external components including potentiometers switches and indicators.

Fine-tuning your audio experience is a breeze with the four potentiometers and the preloaded program. Easily adjust frequencies and volume to meet your specific requirements. Furthermore we have included a programming port for seamless integration with the ICP5 programmer. For complete customization all terminal functions can be tailored to your specific needs using SigmaStudio programming. To simplify programming we have thoughtfully labeled the interfaces with corresponding GPIOs ensuring a straightforward setup process.

Upgrade your audio setup with our DSP Preamp Unit empowering you with unmatched versatility control and customization options.
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 systems 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

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 explanation in the Files&Videos section.
Exquisite Silkscreen Design and Comprehensive Programming Support

To enhance the programming experience we have implemented improvements on the silkscreen design of our preamp unit. Each interface is now labeled with its corresponding program resources making it easier for you to locate and modify the program as needed. We have also provided several blank spaces on the unit for you to mark the functionalities according to your specific needs. Furthermore we are committed to providing comprehensive support for SigmaStudio programming. Our support includes guidance on connecting with ICP for programming detailed explanations of the demo program instructions on making modifications based on the demo program and more. We are dedicated to ensuring your programming experience is seamless and hassle-free.
