Initial Inspection
Inspect the shipping container for damage. If the shipping container, packing material, DAC or
accessories are damaged or missing, notify your dealer and the shipper (if a claim is to be made).
Note: Many shippers require notification and an inspection within twenty-four (24) hours of delivery
to ascertain the nature of damages incurred.
Your EXTREMO DAC has undergone extensive performance evaluations, listening tests, quality
control inspections and a minimum twenty-four (24) hour burn-in period prior to shipment and
should be in a perfect operational condition upon receipt. If the DAC does not operate correctly,
please notify your dealer immediately.
We strongly suggest that you save all packing materials. If the DAC is returned to your dealer the
original packing materials must be used for shipment. Neither North Star Design nor the shipper

Installation
Locate the Extremo DAC as close as possible to its final installation point. Allow access to the rear
panel for making connections.
Front & Rear Panel Function Controls
Before attempting any system interconnection, please familiarize yourself with the front and rear
panel controls of the Extremo DAC. The descriptions below refer to the numbers and letters
associated with the features in the diagram above.
Front Panel
1 STAND-BY PUSHBUTTON
When in stand-by mode, push to switch in Operate mode. When in Operate mode, push to switch in
Stand-by mode.
WARNING: Always put in stand-by the DAC before switch-off the unit by rear panel switch.
2 STAND-BY LED INDICATOR
The Stand-by LED show the operating mode of your converter:
Glows red when the DAC is in Stand-by.
Off the DAC is ready to use.
If the DAC will not turn on, you may want to check the rear panel AC
mains switch , your AC connections, or have your dealer inspect the rear panel fuses.
3 INPUT LED INDICATOR
One of the LEDs glows blue when an input is selected. The LED LAMPEGGIA when a signal is not
present at the input selected. If a PCM input signal is present the input led glows blue and the
frequency led will show the signal frequency.
When the Extremo DAC enter in operating mode the I2S input is checked for the signal presence; if
the CD-Transport is connected with I2S cable, Extremo automatically select this input.
4 FREQUENCY LED INDICATOR
One of the LEDs glows blue when a digital signal whit a recognized frequency is present at the
input. The recognized frequency are: 44.1kHz, 48kHz, 96kHz, 192kHz. If a digital signal with a
different frequency is present at the input, the digital receiver will lock but the frequency will not
displayed.
5 INPUT + PUSHBUTTON
Push this button to select an higher input.
6 INPUT - PUSHBUTTON
Push this button to select a lower input.

player), using a 75 Ohm digital cable provided with RCA connectors (not shipped with the
equipment).
8 COAX INPUT (COAX 2)
Use this input to connect the DAC to the digital output of a source (CD transport, DAT tape, DVD
player), using a 75 Ohm digital cable provided with RCA connectors (not shipped with the
equipment).
9 OPTICAL INPUT (TOSLINK)

improve the sonic performances; ask your North Star Design dealer.
The North Star Design Extremo DAC has been safety-tested and is designed for operation
with a three-conductor power cord. Do not defeat the “third pin” or earth ground of the AC
power cord.
An AC mains switch is located adjacent to the power cord on the rear panel of the amplifier. This
switch may be used to disconnect the power supply from the AC mains without having to actually
unplug the dac from the wall outlet. If you plan to be away for an extended period, or have any other
reason to turn the dac completely off, you may use the AC mains switch.
One slow-blow 315mA (220-240V), 630mA (100-120V) fuses is located inside a small drawer in the
AC main inlet. If you suspect that your AC fuse have blown, disconnect the DAC from the AC mains
and contact your North Star Design dealer for assistance.
Danger! Potentially dangerous voltages and current capabilities exist within the Extremo
DAC, when connected to the AC mains. Do not attempt to open any portion of the DAC
cabinet.
There are no user-serviceable parts inside the Extremo DAC. All service of this product must
be referred to a qualified North Star Design dealer or distributor.
