Dear customer,
thank you for purchasing JOPLIN MKIII. What you have is a first-rate analog-to-digital
converter with many unique features conceived to obtain the best audio performance out
of an analogue source.
Even if sending music to a PC or a Mac is nowadays quite simple, much harder is to
obtain the best sonic performance while doing it, due to intrinsic limits in digital audio
interfaces in computers. Please visit M2Tech website (www.m2tech.biz) to find extensive
literature about this topic.
JOPLIN MKIII overcomes all the limits of your computer’s audio card by implementing the
latest generation hiFace TWO technology, which uses proprietary drivers and
asynchronous data transfer, along with a sophisticated electronic design.
JOPLIN MKIII features a comprehensive set of output connections which suit virtually all
digital equipment around.
JOPLIN MKIII is provided with a very complete set of equalization and filtering options to
accommodate all kind of analogue signals.
We feel that your expectations will be fulfilled by JOPLIN MKIII: you’ll hear your analogue
sources turned into music files or digital streams in a way like never before, prepare for a
whole new experience!
Nadia Marino, CEO
Please note here your JOPLIN MKIII serial number and purchase info for future reference:

1. Unpacking and placing the unit
Lay the package on a table and open the external box by removing or cutting the adhesive
tape seal. Then extract the internal box and open it by lifting the front wing. The following
items are included:
one JOPLIN MKIII ADC;
one wall adapter;
one A-B USB cable;
a remote control;
two AAA batteries.
Should one or more item be missing, please contact your retail dealer.
Remove the JOPLIN MKIII 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 MKIII 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.

3) Standby LED. When the JOPLIN MKIII is in standby mode, this LED is on to indicate to
the user that the device can be switched on by the included remote control.
4) Display with VU-meter. Multifunction OLED display. During normal operation, it
indicates the sampling frequency, the gain, the selected input and the equalization curve.
When accessing the menu, it indicates the menu item and current value. When clipping is
reached on the analogue input, it indicates the status by displaying “CLIP”. It includes a
high resolution VU-meter. This indicates the peak value for both channels. Left channel is
top, right channel is immediately below left channel. It can be shut off by menu.
5) Encoder knob and switch. Push the knob to access the menu. More pushes allow to
navigate the various menu items. When the desired item is accessed, rotate the knob to
choose the desired value for that item. Push the knob one last time to select the desired
value and exit the menu.

5. Connecting and powering the unit
ADVICE: all connections to other equipment in the system must be done when all
equipment are off. Failing to comply to this advice may expose the JOPLIN MKIII to the
risk of damages.
ADVICE: Windows users must install the driver prior to connecting the JOPLIN MKIII to
the PC (please refer to section 6).
Please refer to section 3, “Back Panel Description”.
Connect the “B” plug of a 2.0 USB A-B cable to the USB connector (Figure 2, 13) of the
JOPLIN MKIII.
Connect the “A” plug of the cable to a 2.0 USB port of your computer.
Connect two interconnects to the analogue inputs of the JOPLIN MKIII (Figure 2, 6) and to
the outputs of your analogue 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, optical Toslink™ or HDMI)
from the JOPLIN MKIII to your amplifier’s digital inputs or to a DAC (Figure 2, 9/10/12/14).
If you need to route the output of a digital source to your computer or to the amplifier, you
may connect the source to the JOPLIN MKIII using an RCA digital interconnect (Figure 2,
11).
Connect the wall adaptor provided with the JOPLIN MKIII or one output of the Van Der Graaf
MkII to the supply connector (Figure 2, 15) of the JOPLIN MKIII.
