1 Unpacking and Placement
Unpacking
Procedure
The SXH2 is packaged for maximum protection. To open, sit the
box upright and cut the reinforced tape at the top of the box. The
product can now be removed.
Pull the foam protecting end-caps off either side of the unit and
remove the black material covering.
The SXH2 Headphone amplifier is now unpacked and ready for
further installation.
Note: Please retain all packaging material for future transport.
Box
Contents
1 x SXH2 Headphone amplifier
1 x Product manual
3 x Performance analysis charts
1 x Detachable AC power cord
Placing Your
SXH2
The SXH2 should generally be placed close to your source
equipment, thus keeping interconnect cabling between the SXH2
and associated components as short as practical. This will reduce
the systems susceptibility to radio frequency interference and the
negative effects associated with long cables.
Ventilation
Requirements
The SXH2 is a low power amplifier. Ventilation requirements
are not considered an important factor in product placement.
In the event that the SXH2 is to be incorporated into custom
cabinetry, please refer to the dimensional information provided in
the Physical Dimensions section of the manual (Chapter 12).

2 Instant Install
If you are like us, the first thing you will want to do is to play
your favourite piece of music through your new SXH2. The
following instructions are written to enable you to achieve this as
quickly as possible. These are not comprehensive instructions,
but are designed to enable you to play music now!
Note: Please take the time to read the SXH2 manual thoroughly
as it incorporates many features, which will enhance its
operation.
Placement
The SXH2 is a sensitive low power amplifier and best results
will be achieved when placed away from potential interference
from other components and electrical devices, for example AC
mains cords/outlets, transformers, high power amplifiers,
computers, etc.
Place the SXH2 close or near the source component in order to
make as short a connection as possible.
Turn off associated components
This minimises the potential to damage any other components
when connecting your SXH2 into the system.
Connect source to SXH2
Connect the audio output from the source component to the
inputs at the rear of the SXH2. Refer to Chapter 4 for Rear Panel
information.
Connect headphones to SXH2
Connect a set of headphones to one of the jacks on the front
panel. Refer to Chapter 3 for Front Panel information.
Note: Make sure the nominal impedance of the headphones is
not lower than 8Ω.
Switch on SXH2
Insert the power cord supplied into the rear of the SXH2 and into
the wall. Switch on the socket at the wall and turn on the power
of the SXH2 by setting the power switch down.

8
Caution! Prior to connecting the AC mains, please check the voltage
label on the rear panel to ensure that your unit conforms to
the power supply in your area. Never attempt to connect
the unit to the incorrect voltage.
Switch on source component
Power up your source component and start your favourite
recording. Slowly increase the SXH2 volume to achieve a
comfortable listening level.
CONGRATULATIONS!
Now that you have achieved your first objective, sit back, relax
and please read the rest of the manual at your own pace in your
favourite armchair whilst sipping a hot cup of coffee. You’ll find
the whole experience much more pleasurable whilst listening to
music.

Power LED
This blue LED indicates the power status of your SXH2
headphone amplifier.
Headphone Jacks
Two 6.35mm (¼”) stereo headphone jacks are provided,
allowing a second person to enjoy the pure sound offered by the
SXH2. The construction of the jacks makes for effortless,
crackle and pop-free insertion, and will give a lifetime of
continuous contact performance.
Note: Please ensure that the resulting impedance of the two
headphone sets is not below 8Ω. Use the following
equation to calculate the total impedance: RT= (R1* R2) /
(R1+ R2).
Volume Control
The high-quality, machined aluminium knob is the sole user
interface, reminding the user at every touch of the superior build
quality designed into the SXH2. Volume control motion is
smooth and accurate, providing absolute control with near
infinite gain resolution.
