the latest generation hi F ace T WO technology, which uses proprietary drivers and
asynchronous data transfer, along with a sophisticated electronic design.
JOPLIN MKII features a comprehensive set of output connections which suit virtually all
digital equipment around.
JOPLIN MKII is provided with a very complete set of equalization and filtering options to
accommodate all kind of analog signals.
We feel that your expectations will be fulfilled by JOPLIN MKII: you’ll hear your analog
sources turned into music files or digital streams in a way like never before, prepare

1. Unpacking and placing the unit
Lay the box on a table and open it by separating it from the external paperwork and
removing or cutting the adhesive tape seal. The following items are included:
• one JOPLIN MKII ADC;
• one wall adapter;
• one A- US cable;
• a remote control;
• this manual.
Should one or more item be missing, please contact your retail dealer.
Remove the JOPLIN MKII from the foam enclosure and place it onto a stable base, far
from heat sources. Avoid full sunlight on the unit. Allow for ample room around the
unit for venting.
The JOPLIN MKII is a high efficiency device; therefore it doesn’t produce relevant heat
during its operation. Regardless, it’s recommended to guarantee an adequate air flow
around the unit. Moreover, every time it will mainly be operated by remote control, it’s
recommended to place it so as the remote control’s infrared signals can easily reach
its front panel.
Avoid smoke, moisture, dirt and liquids from reaching the unit. Please note that any
signs of abuse will void warranty coverage.

Please refer to section 3, “ ack Panel Description”.
Connect the “ ” plug of a 2.0 US A- cable to the US connector (Figure 2, 10) of
the JOPLIN MKII.
Connect the “A” plug of the cable to a 2.0 US port of your computer.
Connect two interconnects to the analog inputs of the JOPLIN MKII (Figure 2, 4/5) and
to the outputs of your analog source (be it a turntable, a tuner, a tape recorder or
even the tape rec output of your amplifier).
Connect a digital cable with suitable termination (RCA, XLR or optical Toslink™) from
the JOPLIN MKII to your amplifier’s digital inputs or to a DAC (Figure 2, 6/7/9).
If you need to route the output of a digital source to your computer or to the amplifier,
