Capable
The Emperor Extreme mono power amplifier uses a large toroidal power transformer and generously rated reservoir capacitors to deliver 1,100W RMS into 4 ohms, while providing excellent dynamics and bass control
It will drive any German Physiks loudspeaker and any other makers’ loudspeakers that we are aware of. Its very large output capability ensures that it operates with a healthy power reserve, thereby reducing distortion. Large heat sinks concealed within the case allow the unit to run continuously at high power whilst remaining cool, thereby improving reliability.

Both balanced and unbalanced inputs are provided.

The unit’s gain may be adjusted in three steps via the front panel. Each gain setting provides a slightly different “voice” allowing the customer to adjust the character of their system.

The differences, while not large are intended to allow the user to tip their system’s character slightly one way or the other and so provide some correction for an imbalance.

Technical excellence
The design is fully balanced ensuring a very a very low noise floor
High voltage power supply rails for the low level signal stages and a balanced output stage ensure a very wide dynamic range, which combined with the design’s very wide bandwidth provides exceptional transparency and resolution.

The heart of an amplifier is the power supply, so great care was taken with the design to ensure that it would be able to provide the audio sections with a source of power that was as stable and noise free as possible. which carries the main power.

The low level signal section, power amplifier stage and control section all have their own independent toroidal power transformers. These were chosen for their low external magnetic fields. To minimise the effects of stray magnetic fields, all three transformers are housed in their own screened enclosures.

The amplifier’s incoming mains power is not routed through the power switch, as these can have a detrimental effect on the sound.

This is especially so with very high power amplifiers. Instead, this switch supplies power to the standby circuit and when the front panel On button is pressed, this turns on a high current relay which carries the mains power.

When a large power supply is connected to the mains supply, the initial in-rush current can be high enough to trip circuit breakers or blow fuses. To prevent this, a 4-stage soft start circuit allows the power supply to “slowly” charge before it is switched out of the circuit. This also reduces the stress on the power relay.

High quality power supply capacitors are used with additional decoupling capacitors located physically as close as possible to where they are needed in the circuit.

Great care was also taken with the internal grounding to prevent the introduction of noise
