Installation
We believe that a Heed Audio component should optimally be installed by an approved Heed dealer. Nevertheless, the
procedure is straightforward enough to enable you to install your new Obelisk DT yourself by following the instructions
contained herein. Should any problems be experienced which are not covered here, contact your local dealer. If you are
unable to do so, or problems persist, however, do not hesitate to contact our distributor/reseller in your country (see our web-
site <www.heedaudio.com> “worldwide distributors” for details), or contact us directly at Heed Audio …we're here for you!
When opening the box and unpacking the unit, you will find the following items:
— (1) Heed Obelisk DT digital audio transport
— (1) Heed OBELISK remote control handset
— (1) Heed DigiCon digital signal cable
— (1) IEC-norm mains power cord
— (1) Users Manual
You can place the Obelisk DT on any stable surface. Due to its state-of-the-art topology in all key areas, such as data reading,
sampling, transferring and buffering, it is much less susceptible than most players to environmental or internal influences, such
as the mechanism or power supply, and therefore needs no fancy equipment rack, isolation board or spikes for decoupling.
Before performing any connections or disconnections, ensure that the on/off power
switch (12) of the unit is in the 'off' position.
Always check that the voltage and frequency of the mains supply corresponds to the
specifications marked on the unit!

Insert the power cord's IEC type plug into the power inlet connector (6) of the Obelisk DT.

Connect the power cord's mains plug to your power outlet.
There are two output connections available to transmit digital audio data created by the Obelisk DT to a D-to-A converter:
S/PDIF coaxial (9)
and
TOSLINK optical (10)
.
Theoretically, there are no differences between the signals transmitted via optical TOSLINK or coaxial S/PDIF connectors
— both carry exactly the same information. Selection of one over the other rests mainly on the availability of appropriate
connectors on the chosen equipment and the preference and convenience of the user. In practice, there are pros and cons
with both. TOSLINK cables do not work well (and may even suffer permanent damage) if tightly bent, and their high light-
signal attenuation limits their effective range to ca. 6 metres (20 ft). On the other hand, TOSLINK cables are not susceptible
to ground loops and RF interference, like coaxial cables. In terms of sonic performance, however, we are convinced that
coaxial connections have the edge over optical ones. With its smartly designed output stage, the Obelisk DT can drive almost
any length of coaxial cable with no data loss, to boot.
If you use Heed Obelisk amplification equipped with one of the optional DAC modules (
Heed Audio Dactil-1
or
Dactil-2)
,
you can connect the Obelisk DT directly to the amplifier. When the DAC module is correctly mounted in the Obelisk chassis,
the Number 1 input (in case of the Obelisk PRE it can also be Number 2 as an alternative) transforms into a true co-axial input.
(Either the Left or Right RCA jack may be used to receive the digital signal, but only one of them may be used as such, with
the other remaining unconnected.)
