On the back panel of the remote (see picture for details) you fi nd the “MAINS“ in-
put with the fuse holder and the XLR output “OUT“ with pin 2 carrying the in-pha-
se signal (Pin 2 “hot“). Connect this output to your console or microphone preamp
using a high quality cable. (Check our websie for recommendations; <www.brauner-
microphones.com>)
On the right side of the XLR output you fi nd the 8 pin Tuchel® connector for the con-
nection to the microphone. Below there is the ground lift switch (see paragraph 3.5).
Between the “Mains“ input and the XLR output you fi nd a voltage selector.
The ground lift switch is located on the right side of the XLR output that you fi nd on
the back of the power supply/remote (see picture for details). It detaches the ground
pin (pin 1) of the XLR output from ground. Safety earth is of course never detached in
any position! (By the way, you should under no circumstances detach the safety earth
from any of your cables or plugs. It can lead to lethal accidents if you do so and the
manufacturer of this product is in no way responsible for such damages! Refer to the
safety regulation for further details!) With using the ground lift switch you can solve
hum problems caused by potential differences as they might occur in on location re-
cordings or when the equipment you use is supplied with power from different sour-
ces. To avoid hum problems, you should be sure to use proper power and wiring
techniques, with one central ground and earth potential and no ground loops in
between. The ground lift lets you cut such loops without effecting your safety!
The positions are as follows:
1. Right position: (H)ard-ground: The ground pin (Pin 1) of the XLR connector is
conductively connected to the ground center of the internal circuit.
2. Mid position: Ground-(L)ift: The ground pin is now completely disconnected
from the ground.
3. Left position: (S)oft-Ground: The ground pin is now connected to the ground
via a safety capacitor, that decouples the AC portion of the hum to ground.
Before operating this device you should check for the correct setting of the mains vol-
tage. This can be set to either 115V or 230V. If you are not sure about the voltage in
your environment, you should ask a qualifi ed technician or electrician.
To change the voltage setting you have to switch off and disconnect the power
supply/remote from the mains plug fi rst! Afterwards you can change the voltage
switch to the desired voltage using an apropriate tool such as a screwdriver. Please
note that you should change the fuse when you change the voltage setting. The fuse
is located in a fuse holder that is part of the “MAINS“ voltage input connection device.
You can pull it out to the front using a screwdriver to unlock it from its compartment
and put it back in in the reverse order. For 115V operation 800mA fuses and for 230V
operation 400mA fuses are required. (DIN 41662, time lag).
You should always take care to use the right voltage and fuse confi guration when
using your microphone while you are travelling and working in countries with diffe-
rent mains voltages. You should confi gure to the appropriate voltage setting of
the country you are travelling to, before you start travelling and should confi gu-
re for home use again before travelling home. Also you should always carry some
spare fuses with you, as they are specifi ed in this manual.
