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.

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.

SPEAKER AMP GUARD
Protection of the system power amp / speaker via direct plug-in
Wireless controlled SPEAKER AMP GUARDs use GIGA CANCELLING technology to clear up internal interfering fields, originating in the
system power amp / speaker. From the master unit they receive a dejamming signal, actively penetrating the entire system.
In order to protect the sensitive signal inside the devices against impairment, developers of high grade devices try hard to keep interfering
fields low inside of the devices by use of very low stray field components or by shielding enclosures. Problematic power filter or
conditioner may help keep external field loads away from the device, but the inner interfering fields, caused by the equipment itself and
close to the audio signal, cannot be cleared up this way.
In contrast the SPEAKER AMP GUARD actively operates right in the equipment, in the immediate vicinity of the signal-transmitting
components. With its GIGA CANCELLING technology, it protects the sensitive components of the speaker crossover, the power amplifier
and the speaker cable from sound damaging electrical interfering fields. This makes it an unrivaled solution on the market.

Connecting the SPEAKER AMP PROTECTOR to amplifier resp. speaker

The SPEAKER AMP GUARD MASTER may control one or two SPEAKER AMP GUARD sets of two units
each, which are connected to the terminal at the speaker or to the speaker terminal at the amplifier.
Using two sets can achieve an increase in effectiveness.
The outputs of the amplifier or the inputs of the speakers are available for the connection to the
SPEAKER AMP GUARD units –please test the optimal connection. The white cable is connected to the
positive pole and the black cable to the negative pole. To avoid the risk of damage, the amplifier should
be switched off during installation.
Screw in the antenna for each individual unit; by turning and bending at the hinge it should be brought
into an approximately vertical position for best possible operation. For this purpose, the unit can simply
hang down on the speaker, it can also be attached directly to the speaker with small adhesive strips (see
picture).
Two recommended connection variants for one SPEAKER AMP GUARD set:
1. Connecting to the amplifier
•One unit of the SPEAKER AMP GUARD set is connected to the right speaker output, the other to the left speaker output at the
amplifier.
2. Connecting to the speakers
•One unit of the SPEAKER AMP GUARD set is connected to the right speaker, the second unit to the left speaker.
Connection with two SPEAKER AMP GUARD sets:
Connecting one SPEAKER AMP GUARD set to the amplifier and the other to the speakers.

Setting up the SPEAKER AMP GUARD
The SPEAKER AMP MASTER has three power levels to simply adjust 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
The SPEAKER AMP GUARD MASTER should be placed close to the amplifier or between the speakers.
Usually (power level 1), the master will be operated without the 12V power supply. To maintain its performance, it should be connected to the grid with
CONTROL UNIT and 12V power supply once a year for 15 minutes.
Connect antenna (upright position) and CONTROL UNIT (COUA) to the master, without 12V power supply.
Set the switch of the master to base setting 0.
2. Step: Connecting to amplifier or speakers
See separate page 3.
3. Step: Switch in front –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
CONTROL UNIT 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 –with COUA, without 12V power supply
1 = Power Level 2 –with COUA, with 12V power supply, LEDs on
2 = Power Level 3 –with COUA, with 12V power supply, LEDs high
* note the correct phase (marked with a silver dot) –measure the phase of your socket.

Lasting Effect of the SPEAKER AMP GUARD
The SPEAKER AMP 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 SPEAKER AMP GUARD, the buffering
effect absolutely has to be considered.
If the SPEAKER AMP GUARD is switched off for a short time only, it still takes effect because of the buffering of the power
supply unit.
Disconnect the 12V power supply (if connected) and the CONTROL UNIT from the power grid and the SPEAKER AMP GUARD
MASTER resp. Disconnect all SPEAKER AMP GUARD units from the devices. Additionally remove the antennas of all units,
place the MASTER and the SPEAKER AMP GUARD units on the floor and set the switch of the master to position 2. Keep these
conditions for several hours, preferably overnight. This way you achieve that the SPEAKER AMP GUARD has no effect any
more.
Upon recommissioning the interfering fields will be cleared again fast.
