4. POWER SUPPLY
This product should only be connected to a power supply with a voltage included in the range indicated
on the back panel as shown below in figure 1. The actual format of the labelling may differ from the
picture below, but the meaning will be clear.
Ensure that the maximum power supply voltage does not exceed the upper limit of the operating voltage
range that the unit has been set for, otherwise serious damage may occur. If the voltage of the power
supply that you intend to use is not within the range indicated on the unit’s back panel, do not connect the
unit to the supply and consult your dealer.
5. LOCATION
The preamplifier may be placed on a stand or shelf, provided it is safely able to support its weight.
It may also be placed directly onto the floor, provided that the ventilation slots on the underside of the
preamplifier are not obstructed by a carpet or other floor covering. The clearance between the underside
of the preamplifier and the floor covering should be the same as it would be if the preamplifier was placed
on a hard surface. If necessary, find a means to raise the preamplifier up to ensure the necessary
clearance, or place it on a flat base.
Do not place anything on top of the preamplifier, as this may obstruct the ventilation slots on its upper
surface.
Whilst the preamplifier’s power supply has been designed to have a low external magnetic field, we
recommend that it is not sited close to sensitive items such as phono cartridges or phono stages.
Where ever the preamplifier is located, allow a clearance of at least 5cm (3.5”) above the unit.
A clearance of at least 15cm (6”) should be allowed behind the preamplifier so that cables may be routed
without the need to impose sharp bends.

6. FRONT PANEL CONTROLS AND FUNCTIONS
A. Source selector: Rotate this to select the desired input.
B. Power indicator: Indicates that power is connected to the preamplifier.
C. Remote control receiver window: Do not obstruct this, otherwise operation of the remote control
may be impaired.
D. Ground lift switch: This disconnects the preamplifier’s signal ground from the chassis safety ground
and is useful in eliminating hum when this is caused by a ground loop. This is where there is more
than one ground connection between two pieces of audio equipment, thus forming a loop. This can act
as a single turn coil and stray magnetic fields from nearby equipment and/or power cables can induce
a mains frequency current in this loop, which then produces a hum that is heard from the loudspeakers.
If this is the cause of hum in a system, using the ground lift switch to break this loop will stop the hum.
E. Display brightness button: Successive presses of this button cause the display brightness to
repeatedly step from maximum to minimum, to off. If the display has been switched off, it will come on
for a few seconds when another control is used.
F. On switch: Wakes the unit from standby into normal operation.
G. Volume control: Rotating the control clockwise will increase the volume level and rotating it counter-
clockwise will reduce the volume level. After switching the unit on and before playing music, always
check that the volume control has been set to a safe level. Failure to do this may result in the music
being unexpectedly loud, which in extreme cases may damage your loudspeakers.

6. REAR PANEL FEATURES AND FUNCTIONS
The signal input and output connectors shown are for the right channel. The connectors for the left channel
are arranged in a mirror image of the right channel and are easy to identify.
NEVER make or break connections when the preamplfier is switched on. Failure to
observe this precaution could result in damage to your loudspeakers.
H. Unbalanced input connectors: Connect to sources having unbalanced outputs.
I. Balanced input connectors: Connect to sources having balanced outputs. If a source has both
balanced and unbalanced outputs, we recommend that the balanced input is used as this will usually
produce superior results.
J. 12V trigger output: When connected to another device that has a compatible input, switching the
Emperor preamplifier on will automatically switch this unit from standby mode to on. Switching the Emperor
preamplifier off, will automatically switch this unit back to standby mode. This is most often used in home
theatre systems to control projectors and motorised screens, where, due to their location, easy access to
their power switches may not be available.
K. Power switch: This is the main power switch. When installing the unit, this should be in the off position
as shown in figure 3.
L. 12V trigger output: When connected to another device that has a compatible input, switching the
Emperor preamplifier on will automatically switch this unit from standby mode to on. Switching the Emperor
preamplifier off, will automatically switch this unit back to standby mode.
M. Unbalanced outputs: Connect to the power amplifier unbalanced input.
N. Balanced outputs: Connect to the power amplifier balanced input. Where possible we recommend
that this output is used as it will generally produce superior results.

O. Power supply label: Shows which power supply voltage range the unit has been set for.
If this does not cover the voltage of the power supply you plan to use, do not attempt to
use the preamplifier and consult your dealer.
P. Power inlet: Insert the power cable here.
7. USING THE PREAMPLIFIER IN A STANDARD SYSTEM
This section describes how to connect and set up the Emperor preamplifier for use in a standard 2-channel
system with passive loudspeakers as shown in figure 4. For the purpose of this description we have
assumed that a stereo power amplifier will be used and for convenience have shown an illustration of the
German Physiks Emperor Stereo power amplifier. A pair of mono power amplifiers could be used, as could
amplifiers from other manufacturers, though we cannot guarantee that they will sound as good as German
Physiks electronics.
We have also assumed that this is an established system and the only thing being changed is the
preamplifier. If any other components in the system are also being changed, please refer to the user
manual of the item(s) concerned for guidance.
1. Ensure that all equipment in the system is switched off.
NEVER make or break connections to any amplfier when it is switched on. Failure to
observe this precaution could result in damage to the amplifier and your loudspeakers.
2. Connect right channel output of your main source to either, one of the preamplifier’s right channel
unbalanced inputs (figure 3, H), or one of its right channel balanced inputs (figure 3, I). Where possible,
we recommend that you use the balanced inputs for your main sources, as this will usually produce
superior results.
Connect the left channel output of this source to the matching left channel input of the preamplifier – for
example, if you have used the right channel unbalanced #2 input, you must also use the left channel
unbalanced #2 input.
Repeat this procedure with the remaining sources.
Make sure that all the plugs are pushed fully home into their sockets and that the left and right channels
for each source are not accidentally swapped over.
Try to arrange for the input cables to be separated as much as possible from where power cables will run.
This will reduce the chance of hum and other mains borne noise being picked up by the inputs.

3. Connect the preamplifier right channel unbalanced output, figure 3, M, or right channel balanced output,
figure 3, N, to the power amplifier right channel input. Where possible we recommend that a balanced
connection is used as this will generally produce superior results.
There are two unbalanced and two balanced outputs and these are both numbered 1 and 2. In each pair
the signal from outputs 1 and 2 is the same. For neatness sake, we suggest that you use the number 1
output of the pair chosen.
4. Repeat step 3 to connect the preamplifier’s left channel output to the power amplifier left channel input.
5. Confirm that the preamplifier main power switch is set to the off position as shown in figure 3, K, then
insert the power lead into the preamplifier’s rear panel power inlet, figure 3, P, ensuring that it has been
pushed fully home.
6. Plug the other end of the power cable into the power outlet on the wall, or the power extension block
that you are using. If there is a switch on this, set it to on now.
7. Switch on the power switch on the preamplifier’s rear panel, figure 3, K. The front panel power indicator,
figure 2, B, should now come on.
8. Switch the preamplifier on by pressing the front panel On button, figure 2, F. Allow 30 seconds for the
amplifier to stabilise.
9. Rotate the Volume control, figure 2, G, anti-clockwise and set the volume to minimum.
10. Rotate the Source control, figure 2, A, to select the input connected to the source that you are going
to use.
11. Switch on your music source and allow it to stabilise. Do not start it playing yet.
12. Switch on the power amplifier and allow it to stabilise. This will usually take about 30 seconds but
please refer to the user manual for the amplifiers you are using.
13. Start the music source playing, then slowly turn the preamplifier Volume control clockwise until a
comfortable listening level is achieved.

13
8. USING THE PREAMPLIFIER IN A BI-AMPED SYSTEM
In a bi-amped system, each loudspeaker is driven by two separate power amplifiers. With a 2-way
loudspeaker, one amplifier drives the loudspeaker’s high-frequency driver and the other the low-frequency
driver. Such a system is shown in figure 5. With a 3-way loudspeaker, the second amplifier is used to
drive the low-frequency and mid-frequency drivers. You could also use a separate power amplifier to drive
each section of a 3-way loudspeaker. This is called tri-amping and is more common on very large
loudspeakers such as our Emperor and Gaudi models, where it can yield significant benefits.
For the purpose of this description we have assumed that a stereo power amplifier will be used for each
channel and for convenience have shown an illustration of the German Physiks Emperor Stereo power
amplifiers. Four mono power amplifiers could be used, as could amplifiers from other manufacturers,
though we cannot guarantee that they will sound as good as German Physiks electronics.
Bi-amping can produce an improvement in clarity, as the power amplifiers driving the high-frequency
drivers are relieved of the more strenuous task of driving the low-frequency and mid-frequency drivers.
We have also assumed that this is an established system and the only thing being changed is the
preamplifier. If any other components in the system are also being changed, please refer to the user
manual of the item(s) concerned for guidance.
1. Ensure that all equipment in the system is switched off.
NEVER make or break connections to any amplfier when it is switched on. Failure to
observe this precaution could result in damage to the amplifier and your loudspeakers.
2. Connect right channel output of your main source to either, one of the preamplifier’s right channel
unbalanced inputs (figure 3, H), or one of its right channel balanced inputs (figure 3, I). Where possible,
we recommend that you use the balanced inputs for your main sources, as this will usually produce
superior results.

Connect the left channel output of this source to the matching left channel input of the preamplifier – for
example, if you have used the right channel unbalanced #2 input, you must also use the left channel
unbalanced #2 input.
Repeat this procedure with the remaining sources.
Make sure that all the plugs are pushed fully home into their sockets and that the left and right channels
for each source are not accidentally swapped over.
Try to arrange for the input cables to be separated as much as possible from where power cables will run.
This will reduce the chance of hum and other mains borne noise being picked up by the inputs.
3. Connect the both of the preamplifier’s right channel unbalanced outputs, figure 3, M, or right channel
balanced outputs, figure 3, N, to the right channel power amplifier’s inputs. Where possible we recommend
that a balanced connection is used as this will generally produce superior results.
4. Repeat step 3 to connect the preamplifier’s left channel outputs to the left channel power amplifier’s
inputs.
5. Confirm that the preamplifier main power switch is set to the off position as shown in figure 3, K, then
insert the power lead into the preamplifier’s rear panel power inlet, figure 3, P, ensuring that it has been
pushed fully home.
6. Plug the other end of the power cable into the power outlet on the wall, or the power extension block
that you are using. If there is a switch on this, set it to on now.
7. Switch on the power switch on the preamplifier’s rear panel, figure 3, K. The front panel power indicator,
figure 2, B, should now come on.
8. Switch the preamplifier on by pressing the front panel On button, figure 2, F. Allow 30 seconds for the
amplifier to stabilise.
9. Rotate the Volume control, figure 2, G, anti-clockwise and set the volume to minimum.
10. Rotate the Source control, figure 2, A, to select the input connected to the source that you are going
to use.
11. Switch on your music source and allow it to stabilise. Do not start it playing yet.
12. Switch on the power amplifiers and allow them to stabilise. This will usually take about 30 seconds,
but please refer to the user manual for the amplifiers you are using.
13. Start the music source playing, then slowly turn the Volume control clockwise until a comfortable
listening level is achieved.

SOURCE control is rotated in a clockwise direction. Press the SOURCE - button to cycle through the
inputs in the same order as when the SOURCE control is rotated in an anticlockwise direction.
10. AMPLIFIER BREAK-IN
Like all audiophile equipment, German Physiks electronics require a break-in period from new before
they reach their optimum level of performance. Initially the sound may seem harsh. Please do not be
concerned. The sound will become more relaxed and smoother as the break-in progresses. Break-in
should largely be complete after two or three days of use.
11. CARE OF YOUR PREAMPLIFIER
NEVER remove the product’s covers. This product contains no user serviceable parts.
NEVER attempt to clean the unit with any abrasive materials or any cleaners containing
ammonia, alcohol or other solvents, as these may damage the finish. Solvents may also
constitute a fire hazard.
ALWAYS disconnect the unit from the mains supply before attempting to clean it.
The only maintenance the unit will require is periodic dusting to remove dust and any finger prints from
the chassis. Please use the cleaning cloth supplied with the unit. This cloth should be used dry. Do not
use any form of liquid with it. Additional cloths may be obtained from your local German Physiks dealer,
national distributor or direct from German Physiks.
12. FUSES
NEVER use any fuses other than the types shown below. To do otherwise risks creating
electrical shock and fire hazards, with potentially fatal consequences.
If you suspect that the unit has blown a fuse, you must consult a qualified service technician. Do not
attempt to replace the fuse yourself as the cause of the failure must be investigated in order to prevent
a reoccurrence of the problem and possibly more serious damage. This will not be covered by the
warranty.
