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.

MULTI GUARD
The GIGA CANCELLING technology of the GRID PROTECTOR and the MULTI GUARDs clears up electrical interfering fields,
resulting from the domestic power grid, radiating into the direct environment. The MULTI GUARDs complement and expand
the performance of the GRID PROTECTOR, which takes on the control and coupling function.
Due to GIGA CANCELLING technology GRID PROTECTOR and MULTI GUARD can do without problematic filters and passive
components like capacitors, which are responsible for loss of dynamics, resolution and naturalness; especially at high power
requirements of the power grid.
Application of multiple MULTI GUARDs offers a flexible modular assignment at critical points of the domestic power grid, e. g.
at the different current phases, the protective conductors or in the immediate vicinity of significant interfering sources
(computer, router, etc.). Distributed in the room, they form a comprehensive ROOM SHIELD thanks to their coupling function.
The operating principle and efficiency of the GRID PROTECTOR / MULTI GUARD system are unique and raise the potential of
the entire music system to a completely new level.
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 MULTI GUARD
The use of the GRID PROTECTOR is an indispensable prerequisite for the use of the MULTI GUARD. It takes on the control and
coupling function for all MULTI GUARDs. The GRID PROTECTOR is an extreme powerful central unit and is recommended to
connect to the first slot in the Hi-Fi system power distributor, but may also achieve its best results at another socket, at
different phase or even in another room. In connection with MULTI GUARD, the GRID PROTECTOR always achieves the best
results at the first slot in the Hi-Fi system power distributor. If this is not feasible, select a socket of the same circuit or at least
the same phase.
MULTI GUARDs must be operated with their
associated MASTER. Preferably the MASTER
should have an elevated central position
within the listening room. The MULTI GUARDs
unfolds their effect in their close environment
and thus enable a flexible modular use at
other critical points of the domestic power
grid.
MULTI GUARDs can be connected to free
sockets or power distributers. When
connecting to a power distributor, the first
slot should be used.
Several MULTI GUARDs, appropriately
distributed in the room, can be coupled to
form a comprehensive ROOM SHIELD.

ROOM SHIELD

A common successful approach is to comprehensively clear up the domestic power grid by using the GRID and several MULTI
GUARDs. MULTI GUARDs of the PHASE variant are used to clear up the individual phases of the current conductors and MULTI
GUARDs of the EARTH variant to clear up the protective conductor. MULTI GUARDs of the ROOM variant are used to clear up
the electrical interfering fields that radiate into the room through the power cables installed in the walls and floors of the
listening room.
To do this, it is helpful to know which phases the sockets in the listening room are running on, especially the Hi-Fi power strip,
but also other sockets in the house. Your electrician can tell you this after a look in your fuse box. Alternatively, you can switch
off the individual pre-fuses of the phases one after the other and thus determine at each socket which phase it belongs to.
