THE CONCEPT

•The first high - end power conditioner which completely isolates an audio/video system from high – as well as from

low - frequency power line noises.

•Active DC compensation (patented) eliminates low - frequency line noise, which causes transformer hum.

•8 power outlets for connecting all components of an audio/video system, with all grounds connected to a single

point.

•2 independent AC line filters; allows separation of power supply for digital and analog components.

•Remote on/off possible for entire audio/video system or distributed to selected power outlets.

•Display switchable between indicators for AC voltage or DC portion of mains voltage from the wall outlet.

UNPACKING AND SETTING UP

CAUTION: The power conditioner 948 is very heavy. To avoid injury during unpacking and set-up, this should

only be done by persons who are accustomed to handling such weights.

The power conditioner 948 is shipped inside a plastic protective cover. Make sure that children do not play

with it to avoid the danger of suffocation.

Unpacking To avoid damaging the housing, please do not use pointed or sharp tools to open the box.

Please make sure that the content of the box is complete. If something is missing or you

notice any damage while unpacking, do not hook up the unit. Instead, contact your

authorized dealer.

Content of box The box should contain the following:

CONNECTIONS

All terminals for hook up are located on the rear panel. While connecting the power conditioner, all components of

the music system must be turned off.

CAUTION: Before connecting the unit please check, if the input voltage of the 948 is equal to the local voltage of

your wall outlet. Make sure, the ground lead in your power outlet is working correctly. A missing or faulty ground is

extremely dangerous!

In case of doubt, contact a licensed electrician.

AC mains terminal Make sure the AC mains switch (13) is set to OFF. Connect the appliance connector of the

power cord to the AC mains terminal (14). Then plug the power cord into the wall outlet.

In order to attain optimal listening pleasure you should connect the side of the power

cable's power plug, which is marked with a dot, to the 'hot' phase of the wall outlet. The 'hot'

phase is then also marked with a dot on the AC outlets of the Power Conditioner.

Should you encounter difficulties in finding the 'hot' phase of your AC wall outlet or should

you have additional questions on the set - up of the 948, please contact your authorized

dealer.

AC outlets / filters The power conditioner offers eight AC outlets for connecting audio/video equipment, divided

into four groups. The distribution of the filters to the AC outlets is labelled on the rear of the

unit (FILTER). Should you wish a different distribution of the power filters to the AC outlets,

please contact your authorized dealer.

In the standard version, the 948 offers unfiltered mains voltage for the groups MAINS OUT

3 (17, 18) and MAINS OUT 4 (20, 21). The AC outlets of the groups MAINS OUT 1 (11, 12)

and MAINS OUT 2 (15, 16) have separate filters.

The activated DC compensation affects to all eight AC outlets.

The total power consumption of all connected components should not exceed 2000 W.

The maximum power of each AC outlet should not exceed 2000 W.

CAUTION: Don´t touch the AC outlets of the power conditioner during operation,

because the AC outlets have dangerous voltage.

Always use assembled AC cords to connect your audio/video equipment to the power

conditioner.

Recommended set-up For optimized operation of the 948 power conditioner we recommend connecting your

audio/video equipment as follows:

MAINS OUT 1 (FILTER1) : Preamplifier, Phono Preamplifier, Turntable, FM Tuner

MAINS OUT 2 (FILTER2) : various digital equipment, like D/A converter, CD player,

DVD player

MAINS OUT 3 und 4: variable amplifiers with larger power handling

Should you be using very powerful amplifiers with a continuous power consumption of more

than 500W, we recommend hooking them up to the wall outlet parallel to the 948. The

conditioner function suppressing DC voltage has a parallel effect on all wall outlets and all

connected components.

Remote input The remote input terminal (19) is located on the rear panel beneath the AC mains

terminal (14). This input offers the possibility to switch the 948 on or off from your preamp

or D/A converter. To use this function, the remote in terminal of the 948 has to be

connected with the remote output terminal of the preamp or D/A converter with a suitable

cable. The units which are connected to their respective AC outlets will be turned on at the

same time.

Please understand that we do not include this remote cable, since each customer requires

individual cable lengths. Of course you may request a cable from us or from any authorized

dealer in the necessary length at no charge when mailing in your warranty certificate.

The distribution of the remote on/off function to the AC outlets is labelled on the rear of the

unit (SWITCHED).

In the standard version only the power conditioner is turned on or off by the remote function.

For other options of remote on/off functions, please contact your authorized dealer.

OPERATING CONTROLS

With the exception of the AC mains switch, all operating controls are located on the front panel. To operate the unit it

must be connected to the AC supply.

AC mains switch The AC mains switch (13) which turns AC power to the unit on and off is located on the

rear panel above the AC mains terminal. By switching to the ON position the transformers

are powered up, the AC outlets are switched on and the stand-by LED (4) lights up.

Power button The power button (7) switches the power conditioner on and off. When the unit is switched

on, the power LED (2) will illuminate. While turned off, the stand-by LED (4) lights up,

indicating that the unit is in stand-by mode.

Always use the power button (7) first to switch off the unit before setting the AC mains

switch (13) to OFF.

Conditioner button Pressing the conditioner button (6) switches the automatic DC compensation on and off.

The activated DC compensation is indicated by the conditioner LED (1). If the DC

compensation is activated and the display (3) is switched to show the DC portion of the

mains voltage, the value displayed will decrease to about zero.

AC•DC button Pressing the AC•DC button (10) switches the display (3) of the power conditioner between

showing the AC voltage (AC•DC LED (5) is off) and showing the DC portion of the mains

voltage (AC•/DC LED (5) is on).

Display button The display of the power conditioner can be turned off with the display button (9). All

functions of the unit remain active. Pressing the display button (9)again, turns the display

back on.

ERROR PROTECTION

The power conditioner 948 has a sophisticated protection circuitry which is designed to protect the unit in case of a

failure.

Overheating In the event, that the unit exceeds the maximum allowable operating temperature, the

overheat protection automatically switches off the DC compensation. This will be indicated

by the illuminated TEMP LED (8), while the conditioner LED (1) turns off. When the unit

has cooled off, the conditioner function can be reactivated by pressing the conditioner

button (6).

GENERAL INSTRUCTIONS

Operating temperature An operating temperature that is too high or too low may cause malfunctioning. We

therefore recommend letting the 948 sit for a while after unpacking and before connecting

and operating it.

Terminals The pins of the connecting terminals on the back panel should not be touched by fingers

under any circumstances. Static discharges may damage the electronic circuitry inside the

unit.

Heat development Be careful when touching the housing – it may get quite warm during operation.

Reset If the unit does not react when pressing the control keys on the front it may be reset to

normal operation by switching it off and back on using the AC mains switch in the back.

Lightening strikes During the summer months, malfunctions often occur due to voltage spikes in the power

lines after lightning strikes. Completely unplugging the power cord offers the only effective

protection. Merely switching the 948 off does not suffice since voltage spikes are able to arc

over separated contacts.

Interconnects We supply custom-made balanced as well as unbalanced interconnect cables and speaker

cables of any length to ensure highest-quality signal paths for our components. The

impedance of our cables is ideally matched to all BURMESTER components.

For the cleanest power supply we recommend our triple-shielded power cord BURMESTER-

POWER.

Fuses The fuses are located inside the unit and should be changed only by a qualified technician.

Voltage Check before operating the 948 to see if the voltage setting shown on the back panel below

the AC mains input conforms to voltage of your household power supply. Any change

should only be done by an expert.

Warranty We offer warranty for this unit provided the 948 has been hooked-up and operated

correctly, is mechanically undamaged.

Opening the unit, modifying it or dismantling outlets will void the warranty.

Care Never clean the housing with a wet cloth or chemical cleaning agent. Always make sure that

no liquid gets into the housing.

CAUTION Before opening the housing or changing the fuses always unplug the unit from the

wall outlet. DANGER OF ELECTRIC SHOCK!
