For orders above ₹10,000 where a partial advance payment is collected:

  1. Order cancellation is allowed only within 24 hours of placing the order.
  2. After 24 hours, the advance amount will not be refunded, as procurement of the product is initiated immediately.

The Wondom ADAU1701 Digital Signal Processing Preamp Board is a powerful, high-performance audio processor designed for audiophiles and DIY sound engineers building 2.1 or 4.0 audio setups. Powered by a 28/56-bit digital signal processor engine with a 24-bit analog-to-digital and digital-to-analog converter resolution ratio at a 48 kilohertz sampling rate, this board delivers incredible sound clarity. It serves as an unbalanced 2-input, 4-output preamp unit, allowing you to fine-tune your sound systems with extreme precision. The hardware comes equipped with four onboard potentiometers for manual high-pass filter, low-pass filter, and master volume adjustments, giving you immediate tactile command over your frequencies. For advanced custom tuning, it supports full SigmaStudio programming when paired with an external ICP5 programmer module. Housed in a compact aluminum enclosure with integrated mute and phase switches, this tone board is perfect for custom home theaters, active crossovers, and bespoke speaker configurations.

Connect your analog audio source to the unbalanced inputs using the RCA jacks. Wire the 4-channel outputs to your amplifiers or active speakers. Power the device using a stable direct current 5 Volt supply through the integrated USB Type-C port. Use the four onboard potentiometers to adjust the volume, high-pass filters, and low-pass filters manually. For custom digital crossover configuration, connect the board to your computer via a compatible ICP5 programmer tool and program it using Analog Devices SigmaStudio software.

Generic High-grade fiberglass printed circuit board, premium aluminum enclosure, onboard potentiometers, integrated circuits, digital-to-analog converters, analog-to-digital converters, copper wiring connectors, and metal switches.

FAQs

Do you need help with the digital crossover configuration?

Yes, we can provide guidance. The board comes pre-loaded with an open-sourced demo program that handles standard 2-way digital crossover configurations out of the box, but you can also completely customize the slopes, frequencies, and parametric equalizer using SigmaStudio.

Do you have an ICP5 programmer for SigmaStudio?

The Wondom ADAU1701 board supports SigmaStudio programming, but it requires a separate connection via a compatible expansion programmer like the Wondom ICP5. The programmer is sold separately and acts as the bridge between your personal computer and the digital signal processing chip.

What power supply is required for this digital sound processor board?

This board runs efficiently on a direct current 5 Volt power input. It features a modern, convenient USB Type-C port interface that makes it easy to power using standard adapters or development kit power blocks.

Is this Wondom ADAU1701 audio processor board an authentic import available in India?

Yes, this is a 100 percent authentic Wondom product imported directly from trusted global distribution channels. Dropy India sources these specialized audio components directly from international supply chains to guarantee genuine quality for Indian DIY audiophiles.

What physical control switches are included on the enclosure?

Aside from the four dial potentiometers used for tuning filters and output volumes, the aluminum housing also includes dedicated onboard mechanical switches for instant Mute and Phase alignment adjustments.
