the JOPLIN is an A to D converter that is capable of turning any analog source into a digital file. It can digitize to any sample and bit rate from 44.1 kHz 16 bit to 384 kHz 32 bit. The inquiries came from all sorts of people with many different applications. Straight from Pisa, Italy and attached below are four applications, with flow diagrams, showing how the JOPLIN can be used for:

1. A digital grabber from any analog source - radio, television, cassette, et cetera
2. A digital archiver for vinyl collections!
3. A digital input to a DAC from an analog source in real time
4. A digital bridge between a digital source and a computer with no digital inputs.





DETAILS

High-speed asynchronous USB connection. Single-ended stereo input on RCA. S/PDIF, AES/EBU and Toslink digital outputs. Auxiliary S/PDIF input for bridging. Selectable input gain 0dB to 65dB. Wide choice of equalization curves in digital domain. Various filter options (anti-rumble, anti-hiss, MPX). Remote control. Encased in a stylish aluminium case.

FEATURES

Joplin is a high performance A/D converter capable of handing up to 384kHz sampling rates and 32 bits resolution (USB output). It features a high speed asynchronous USB input based on the hiFace Two technology, further developped to allow for higher sampling rates. A comprehensive output set (S/PDIF on RCA, AES/EBU on XLR and optical on Toslink) provide great connection versatility. Also, an auxiliary S/PDIF digital input on RCA allows for re-using the digital connection used for the Joplin for a digital source, as well as for redirecting the output from a digital source to a computer which is not provided with an S/PDIF input. Despite its price, Joplin encopasses a leading edge technology for data handling and processing. An FPGA is used to provide a seamless connection between the ADC IC and the USB port (both operating in master mode for low jitter reasons), as well as for a large number of important clock and data routing tasks, not to mention the VU-meter drive.

The analog stage is based on the best PGA (Programmable Gain Amplifier) available on the market, and allows for gain as high as 65dB (equivalment to 0.95mVrms for 0dBFS). A comprehensive set of equalization curves can be selected, to accommodate all phono formats ever used from 1925 to the present day, plus eq curves for reel-to-reel tapes with straight output from the playback head.
The small size and stylish look of the Joplin allow for a uninvasive placement in every living space.

I've looked up the price, the most important number. Not for the feint of heart.

But more to a question many vinyl fans would ask, why would you ruin a perfectly good analog signal to digital?

Yep.
Just listen.
