Product Details

This is a clever ADC/Phono from M2Tech's Rockstar series.

The Joplin MkIII is exactly what you need to connect your turntable to your computer or to your all-digital hi-fi system.

The versatile analogue front-end, with settable gain up to 65dB and variable input impedance allow user to connect every phono cartridge without the need for a phono preamplifier. In case a phono preamplifier is to be used, the analogue input may be set to 0dB gain and 47 kOhms impedance, to behave as the line input of every preamplifier or integrated amplifier

The internal processing block allows user to enable phono equalization in digital domain, choosing one out of several phono curves available.

Digitized data are sent to a wealth of digital outputs, as well as to the USB port for recording into a file on a computer. An auxiliary SPDIF digital input enables a digital communication channel to the computer, actually providing it with a digital input.

The extremely high signal-to-noise ratio, the vanishingly low distortion and the precision of the equalization curves make for a virtually transparent link between your turntable cartridge and your digital preamplifier and your computer.
