Dear customer,
Thank you for your purchase of a SCHNERZINGER product.
Please take the time to precisely read the information in this guide. You
will find important instructions to use your product and hints for the
optimal integration into your Hi-Fi system.
This guide facilitates your use of the product, promotes understanding
its functional characteristics and helps you to obtain the full efficiency
of the product.
We hope you enjoy your new SCHNERZINGER product.
Please clean the product with a non-scratching dry duster only. Avoid
using cleaning agents.
A potting compound in the devices protects the innovative GIGA
CANCELLING technology with its particular electrical components
specially manufactured for SCHNERZINGER against direct access and
screening via X-ray or magnetic field applications. A slight rustling
caused by this potting compound is normal and does not result in any
functional impairment. There are no informed crystals in the devices.
In case of malfunctions contact your SCHNERZINGER dealer. Please do
not attempt to service the device yourself or to open it, in that case you
will lose your entitlement for our manufacturer warranty.
In the case of damages at the power plug or power cable please initiate
an exchange at SCHNERZINGER via your dealer.

ROOM GUARD
The ROOM GUARD offers a cost-effective, area-covering basic interference suppression to clear medium to strong high
frequency interfering fields radiating into the room.
Due to GIGA CANCELLING technology the ROOM GUARD can do without problematic filters and passive components like
capacitors, as even the fastest of these components tend to slow down electrons and delay transmission, significantly reducing
the possible effectiveness, especially in the “ultra-fast” high frequency range.
PROTECTOR SYSTEM
The music reproduction quality of an audio system is highly affected by low and high frequency electrical interfering fields,
caused by Wi-Fi, cellular radio, power lines etc. With the PROTECTORS and their integrated trendsetting GIGA CANCELLING
technology, SCHNERZINGER has developed a product category that actively eliminates the sonic effects of low and high
frequency interfering fields.
The PROTECTORS significantly enhance the transmission quality of audio systems. The sonic effects include an astonishingly
higher spatial depth and resolution as well as increased broad and fine dynamics in music reproduction.
Utilizing the operating principle and efficiency of the GIGA CANCELLING technology, the SCHNERZINGER PROTECTORS
represent a unique solution in the market.
An important health aspect: protector technology does not increase radiation exposure within the room.

Use of ROOM GUARD
ROOM GUARDs must be operated with their associated MASTER. Preferably the MASTER should have an elevated central
position within the listening room. The ROOM GUARDs unfolds their effect in their close environment (radius app. 3 meters)
and thus enable a flexible modular use at critical points of the listening room power grid.
ROOM GUARDs can be connected
to free sockets, ideally close to the
room corners.
Several ROOM GUARDs,
appropriately distributed in the
room, form an area-covering
ROOM SHIELD thanks to the
coupling function controlled by the
master unit.

Setting up the ROOM GUARD
The ROOM GUARD MASTER has three power levels to simply adjust the GIGA CANCELLING technology via a toggle switch. This
makes it possible to adapt to any interference field spectrum.
Changes need some time to take effect mostly. Therefore at each of the following steps you should wait for app. two minutes
before judging.
Do not change the results as determined from the previous steps when you do the subsequent steps.

1. Step: Base setting master
Preferably the master should have an elevated central
position within the listening room. Usually (power level
1), it will be operated without the 12V power supply. To
maintain its performance, it should be connected to the
grid with its 12V power supply once a year for 15
minutes.
Connect antenna (upright position) to the master,
without 12V power supply.
Set the switch of the master to base setting 0.
* note the correct phase (marked with a silver dot) –measure the phase of your socket.

2. Step: ROOM GUARD ROOM
Connect the first ROOM GUARD*. By turning and
bending at the hinge the antenna has to be brought to
upright position for proper functioning.
Different slots in the listening room are tested and the
option with the best effect is retained.
The best slots for further ROOM GUARDs are iteratively
tested and each time the option with the best effect is
retained.
The best effect is usually achieved when the ROOM
GUARD units used in the listening room cover all room
walls, e. g. by placing the units near all 4 room corners,
and form a high-performance ROOM SHIELD.

3. Step: Switch at the master –adjustment of the
power level:
If power level 1 is not sufficient for the present
interference field spectrum, 2 additional power levels
can be activated. This requires the permanent
connection of the 12V power supply* to the master and
the grid. The 12 Volt power supply should be connected
to a power circuit separate from the Hi-Fi system –
ideally even to a different power phase.
0 = Power Level 1 –without 12V power supply
1 = Power Level 2 –with 12V power supply, LEDs on
2 = Power Level 3 –with 12V power supply, LEDs high

Lasting Effect of the ROOM GUARD
The ROOM GUARD constantly operates to clear up interfering fields effectively and comprehensively.
If after a while you once want to hear the performance of your system without your ROOM GUARD, the buffering effect
absolutely has to be considered.
If the ROOM GUARD is switched off for a short time only, it still takes effect. But it only requires up to 15 minutes to reach its
maximum performance.
Remove the ROOM GUARD MASTER and all ROOM GUARD units from the power grid and set all antennas to a horizontal
position. Keep these conditions for several hours, preferably overnight. This way you achieve that the ROOM GUARD has no
effect any more.
Upon recommissioning the interfering fields will be cleared again fast.
