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 and position 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 amplifier 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
amplifier are not obstructed by a carpet or other floor covering. The clearance between the underside of
the amplifier and the floor covering should be the same as it would be if the amplifier was placed on a hard
surface. If necessary, find a means to raise the amplifier up to ensure the necessary clearance, or place
it on a flat base.
Do not place anything on top of the amplifier, as this may obstruct the ventilation slots on its upper surface.
Whilst the amplifier’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 amplifier 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 amplifier so that cables may be routed
without the need to impose sharp bends.

6. FRONT PANEL CONTROLS AND FUNCTIONS
A. Power indicator: Indicates that power is connected to the amplifier.
B. Input: Switches between the rear panel balanced and unbalanced inputs.
C. Gain selector switch: Pressing this button cycles the unit through the three gain settings. Each
setting has a slightly different voicing, which allows the user to adjust the character of their system.
Successive presses of this button will cause the gain setting to cycle from nominal (0dB), to -9dB, to
+3B and then back to nominal. The voicings for each setting are shown below.
Gain
Voicings
0db
Neutral
-9dB gain
Warm
+3db gain
Analytical
To avoid sudden jumps in volume that may damage your loudspeakers, always reduce the
amplifier’s volume setting to minimum before changing the gain setting.

D. Ground lift switch: This disconnects the amplifier’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.
7. REAR PANEL FEATURES AND FUNCTIONS
NEVER make or break connections to the amplifier when it is switched on. Failure to
observe this precaution could result in damage to the amplifier and your loudspeakers.

results.
J. 12V trigger input: When this is connected to a device with a compatible trigger output, switching the
connected device on or to standby, will automatically switch the amplifier on, or to standby.
K. 12V trigger output: When this is connected to a device with a compatible trigger input, this device will
be switched either on, or to standby as commanded by the signal on the trigger input J.
L. Loudspeaker output terminals: The signal supplied to each pair of terminals is exactly the same.
Two sets of terminals are provided to make bi-wiring easier.
NEVER make or break connections to the amplifier when it is switched on. Failure to
observe this precaution could result in damage to the amplifier and your loudspeakers.
M. Power inlet: Insert the power cable here.
N. Power switch: This is the main power switch. When installing the unit, this should be in the off position
as shown in figure 3.
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 amplifier and consult your dealer.

8. USING THE AMPLIFIER IN A STANDARD SYSTEM
This section describes how to connect and set up the Emperor Mono amplifier for use in a standard 2-
channel system with passive loudspeakers as shown in figure 4. For convenience we have shown the
German Physiks Emperor preamplifier in the illustration, but any other manufacturer’s preamplifier could
be used, though we cannot guarantee that it will sound as good as with German Physiks electronics.
We have also assumed that this is an established system and the only thing being changed are the power
amplifiers. If any other components in the system are also being changed, please refer to the user
manual(s) 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 amplifier when it is switched on. Failure to
observe this precaution could result in damage to the amplifier and your loudspeakers.
2. Connect the preamplifier’s right channel output to the right channel mono amplifier’s unbalanced input
(figure 3, H) or its balanced input (figure 3, I). We recommend that the balanced input is used as this will
usually produce superior results.
3. Repeat the above step to connect the preamplifier’s left channel output to the left channel mono
amplifier, using the same interface as before.
Make sure that the plugs are pushed fully home into their sockets and that the left and right channels 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.
4. Connect the right channel loudspeaker cables to the right channel mono amplifier’s loudspeaker
terminals, figure 3, L.
Figure 4. Standard 2-channel system.

13
There are two pairs of loudspeaker terminals and the same signal is provided to each. Use which ever set
is convenient.
Ensure that that the loudspeaker’s +ve terminal is connected to the amplifier’s +ve loudspeaker terminal
and that the loudspeaker’s -ve terminal is connected to the amplifier’s -ve loudspeaker terminal.
These terminals will accept both banana plugs and spade terminals. Where possible we recommend that
cables fitted with spade terminals are used, as this gives a superior connection.
If using banana plugs, ensure that each plug is pushed fully home into the hole in the centre of the terminal.
If using spade terminals, loosen the loudspeaker terminal cap by turning it anti-clockwise a few turns to
allow the spade to be inserted so that it can be pushed up against the centre of the terminal, then tighten
the terminal cap so that the spade is securely held.
Only tighten the terminal by hand. Never use any sort of tool, as this may result in damage to the terminal.
Arrange the loudspeaker cables so that they lie smoothly without any sharp bends or kinks. Also take care
that the cables are not stressed where they are joined to the terminations (banana plugs or spade
terminals).
5. Repeat the above step to connect the left channel loudspeaker cables to the left channel mono amplifier.
6. Confirm that the rear panel power switches on both mono amplifiers, figure 3, N, are in the off position,
then connect the power cables to the rear panel power inlets, figure 3, M, ensuring that they have both
been pushed fully home.
7. Connect the other ends of the power cables to the power outlets on the wall, or extension block. Make
sure that the power is not switched on at this stage.
8. Connect the preamplifier to the power supply, switch it on and allow 30 seconds for it to stabilise.
9. Set the volume control to minimum, and select the input connected to the source you will use.
10. Ensure that a source is connected to the preamplifier and is ready to play. Do not start it playing yet.
11. If there is a switch on the power outlets you are using for the mono amplifiers, switch this on, then
switch on the power switches on the mono amplifiers’ rear panels, figure 3, N. The amplifiers are now in
standby mode and the front panel power indicator on each amplifier, figure 2, A, should come on.
12. Switch the mono amplifiers on by pressing the front panel On buttons, figure 2, G. Allow 30 seconds
for the amplifiers to stabilise.
13. Use the Input button, figure 2, C, to select the appropriate input on each mono amplifier.
14. We recommend that initially the amplifiers’ gain be set to 0dB (standard setting). This gives the
amplifiers’ a neutral voicing.
Press the Gain button, figure 2, D, on each mono amplifier’s front panel once. The display will show the
word GAIN for about 3 seconds, followed by the current gain setting in dB and the voicing of that setting.
Press the GAIN button again as necessary until the gain is set to 0dB.
To avoid sudden jumps in volume that may damage your loudspeakers, always reduce the
amplifier’s volume setting to minimum before changing the gain setting.
15. Start the source playing and slowly increase the preamplifier volume control until a comfortable
listening level is achieved.

14
We suggest that you experiment with the gain settings to find the one that produces the sound most to
your taste. To avoid sudden jumps in volume, always reduce the preamplifier volume setting to minimum
before changing the amplifier gain setting. As the amplifier’s sound may change during the first few days
of use as it settles down, we recommend that you listen to the gain settings again after this to confirm that
you have found the one you like best.
9. USING THE AMPLIFIER IN A BI-WIRED SYSTEM
If a loudspeaker can be bi-wired, it will have a separate set of input terminals for each section of its
crossover: one set for the tweeter section and one set for the bass/mid-section. To bi-wire such a
loudspeaker, you simply use a separate loudspeaker cable to connect each section of the crossover to the
amplifier. To make this easy, the Emperor Extreme Mono amplifier has two sets of loudspeaker terminals
for each channel.
Bi-wiring can produce a useful improvement in sound quality, but bearing in mind the potential cost of an
extra set of loudspeaker cables, we recommend that the user borrows some extra cables first to see how
well this works with their loudspeakers. They can then decide if the improvement justifies the cost.
10. 12V TRIGGER
When using this feature on German Physiks Emperor electronics, only use trigger cables
that are fitted with 3.5mm stereo plugs. This is the standard employed by most other
manufacturers. If you are using German Physiks Emperor electronics with other makers’
equipment, refer to the appropriate user manuals to confirm the type of cable that should be used.
When units using this system are connected together, switching the unit at the top of the chain from
standby to on, will result in all the other units in the chain being switched on. The following connection
instructions refer to an all German Physiks Emperor electronics system, with an Emperor preamplifier.
1. Ensure that all equipment in the system to be connected is switched off at the rear panel power switches.
2. Connect a trigger cable to either of the preamplifier’s LINK OUT sockets – preamplifier manual, figure
3, J or L.
3. Connect the other end of the cable to the LINK IN socket on the first mono amplifier – figure 3, J.
4. To connect further units, connect a trigger cable between the LINK OUT socket on the last unit
connected and the LINK IN socket on the next unit.
5. Confirm that the plugs on all the trigger cables have been pushed fully into their respective sockets.
6. When all units have been connected, switch on the rear panel power switches.
7. If the preamplifier’s front panel ON button is now pressed (preamplifier manual, figure 2, F), all the other
connected units should come out of standby.

15
11. 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.
12. CARE OF YOUR AMPLIFIERS
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.
13. 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.
