GRID PROTECTOR
The GIGA CANCELING technology of the GRID PROTECTOR penetrates and clears up
the entire domestic power grid from sound damaging interfering fields, caused by the
electrical devices in the home (computer, refrigerator, cooktop, router, etc.).
*
Note the correct phase
when connecting to
the power grid
(marked with a silver
dot on the plug of the
device).
Measure the phase of
the socket accordingly.
Setting up step by step
1. Power connection and antenna
Connect* the GRID PROTECTOR at the first slot of the HiFi system power distributor. If
this is not feasible, select a socket of the same circuit.
Operate initially without 12V power supply.
Connect antenna (upright position).
2. Basic setting
All three switches in base setting 0, the LED is off.
The switch POWER usually remains in the basic setting 0, the LED remains off.
3. Switch BANDWIDTH
First listen in the basic setting and then switch to position I and II. Listen in comparison
and keep the best setting.

Setting up step by step
4. Switch CLOCKING
First listen in the basic setting and then switch to position I and II. Listen in comparison
and keep the best setting.
5. Increase in performance (switch POWER)
Usually the setting is now complete.
But if the base setting is not sufficient for the present interference field spectrum, the
permanent connection of the 12V power supply to the grid is required.
It should be connected to a power circuit separate from the HiFi system –ideally even
to a different power phase.
Do not change the optimal switch setting for BANDWIDTH and CLOCKING determined
in steps 3 and 4!
Listening tests of the power levels, starting with switch position I (LED on), than switch
position II (LED high).
If there is no improvement, return to POWER basic setting:
Remove the 12V power supply again, POWER switch position 0, LED stays off.
Additional information
The GRID PROTECTOR can also affect the HiFi system very effectively in other places in
the house. Used e.g. in the kitchen or at the workplace in the same circuit of the
electrical devices there, it can also have a positive influence on the current phase and
protective conductor interferences. This effect can extend into the HiFi room.
Conclusion: just give it a try.
The procedure for setting the switches as described above is a recommendation and
in most cases the most effective variant.
All variants of switch positions in all combinations are allowed, the device is not
damaged when trying all possibilities.
If after a while you once want to hear the performance of your system without your
GRID PROTECTOR, the buffering effect absolutely has to be considered. If the GRID
PROTECTOR is switched off for a short time only, it still takes effect because of the
buffering of the power supply unit.
Detach the power cable of the GRID PROTECTOR for the power grid (if connected also
the 12V power supply). Remove the antenna, place the unit on the floor (best stored
on the side) and set the middle switch POWER to position 0. Keep these conditions for
several hours, preferably overnight. This way you achieve that the GRID PROTECTOR
has no effect any more.
Upon recommissioning the interfering fields will be cleared again fast.
To maintain its performance, the GRID PROTECTOR it should be connected to the grid
with the 12V power supply once a year for approx. 15 minutes.
Please clean the product with a non-scratching dry duster only. Avoid using cleaning
agents.
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.
Enjoy listening!
