Dear Audioplan customer,

You have decided to purchase one of our power supply products. We

thank you for the trust you have placed in us.

In order to be able to exploit the full potential of the devices, to avoid

damage and to achieve the best possible sound, please observe the

following important instructions.

1. The Audioplan power supply units should only be connected with

the hifi-system switched off.

2. Observe the maximum permissible load capacity of the filter

modules. Overloading can lead to damage and overheating.

3. Do not open the units. Mains voltage is running inside. This is

dangerous to life. High voltages can be stored in the unit for a

few minutes even after disconnection from the mains. There are

no parts inside the filters that can be replaced by the user. The

fuses are accessible from the outside.

4. Disconnect the unit from the mains before replacing the fuse! Al-

ways replace with the same type and value. The value is printed

on the respective unit. Never use stronger fuses as they might

damage the unit.

5. Place the units on a firm, dry surface, e. g. behind the hifi-rack on

the floor. At most the units become hand-warm during operation.

Special ventilation is therefore not necessary.

6. Avoid contact of the units with water. Penetrating water can

cause short circuits and damage to the filters. In such a case,

please contact your dealer.

7. The Audioplan filter units may only be used in closed, dry rooms

for the operation of an audio, video or audio-visual system. All

other uses are not permitted and may be dangerous. Audioplan

is not liable for damage caused by improper use or incorrect

operation.

The Audioplan power supply,

a system of complementary devices.

Why are there different power supply units and what is their func-

tion?

If you look at an audio or AV system consisting of several components,

you can distinguish between three basic types of unwanted interaction.

Each of them requires a specific countermeasure.

1. Dynamically changing potential differences caused by the cur-

rent distribution to the individual components of the hifi-system:

If the devices of a hi-fi system are connected to a conventional distrib-

utor or different sockets in a room or, even worse, to different power

circuits in the house, dynamically fluctuating potential differences are

unavoidable due to the internal resistances of the cables. These po-

tential differences lead to compensation currents on the signal lines

between the units. To reduce these to a theoretical minimum we have

developed the PowerStar. Since with the PowerStar all connected units

in the outer sockets refer to the unit in the central socket in terms of

potential, there are practically no more compensation currents.

2. Interference caused by devices in the AV system itself, we call it

internal interference:

All devices generate mains-noise themselves and thus influence

each other. Ideally, all devices of a system should be filtered sep-

arately, to remove this interference. For a gradual build-up of the

filter chain, it is recommended to filter the strongest interferers first.

Switch-mode power supplies and digital devices produce particu-

larly unpleasant interference. To prevent their interference from

reaching the other units of the hi-fi system, we developed the Pow-

erPlant. The PowerPlant is therefore the basic filter for CD players,

D/A converters and other digital components. Next, the phono stage,

the record player and the preamplifier should be equipped with the

PowerPlant for additional filtering. Finally the power amplifier(s) or

integrated amplifier shall be filtered with PowerPlant.

3. Interference from outside, from the mains, we call it external

interference:

This noise enters the system via one or more mains supply cables.

Since the relevant interference for the sound-quality is high-fre-

quency, the noise can spread throughout the entire system via the

signal cables or their earth connection. Therefore, the ideal solu-

tion is to have all components of the system separated from the

mains by a filter. This requirement can be met by separate filters

for each component.
