Description
Joplin MkIII ADC/Phono
The perfect analog port for a digital audio system
Turn your computer into a high resolution audio recorder!
The Joplin MkIII is exactally what you need to connect your
turntable to your computer or to your all-digital hi-fi system.
The versatile analog 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 analog 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.
Joplin MkIII works great together with…
Van Der Graaf MkII Low Noise Power Supply
…to add resolution and weight to the sound.
Young MkIII DAC
…to provide the Joplin MkIII with a high quality analog
output.
