DIY PreDIGin add-on
Please note: This product is only compatible with the DIY PreAmplifier
The DIY PreDIGin add-on is designed to complete the DIY PreAmplifier. DIY PreDIGin is the digital companion for audio enthusiasts seeking the ultimate listening experience.
At the heart of the DIY PreDIGin lies cutting-edge technology, including high-quality components such as the AK5574 ADC IC, dual CS43198 DAC ICs operating in Mono mode, SRC4392 for superior sample rate conversion, and the ADSP21489 DSP for advanced signal processing capabilities.
One of the standout features of the DIY PreDIGin is its exceptional DAC audio specifications. With an output level of 14dBu, distortion rated at an impressive -117.5dB, a signal-to-noise ratio of 128.5dB, and a dynamic range of 127dB, the DIY PreDIGin ensures pristine audio reproduction, capturing every nuance of your favorite music
Versatility is another key strength of the DIY PreDIGin, offering support for a wide range of audio formats and connectivity options. Whether you prefer traditional sources like S/PDIF, Optical, and AES/EBU up to 192kHz/24bits, or cutting-edge digital interfaces like USB type B and Network1 up to 384kHz/32bits, the DIY PreDIGin has you covered. Additionally, Bluetooth connectivity at 48kHz/16bits provides convenient wireless streaming options.
The PreDIGin add-on comes with a network option, which includes an internal USB-audio input. The user is required to purchase and install a Raspberry Pi (models 2 to 5) inside the DIY PreAmplifier. A dedicated space for this is provided. The Raspberry Pi functions as the internal processor, working together with the software of your choice. There are many software options available, each offering its own advantages and disadvantages, so it is important to carefully select the one that best suits your needs.
For those looking to take their audio setup to the next level, the DIY PreDIGin includes a FusionConnect board. This optional feature transforms your DIY PreAmplifier into the master device in a FusionAmp setup, offering seamless integration and enhanced control over your entire FusionAmp based audio system.
With its exceptional performance, versatility, and innovative features, the DIY PreDIGin sets a new standard for DIY audio enthusiasts. Elevate your listening experience and unleash the full potential of the DIY PreAmplifier with the DIY PreDIGin add-on.
