Operation
• Should the device be operated on phantom power of another device that is connected to one
of the two outputs OUTPUT (7), the POWER (6) switch need not be pressed. Even if a battery
is installed, the power supply is primarily via the phantom power.
• Should the device be operated on battery, press the POWER (6) switch to turn it on.
• The POWER (6) switch is colour-coded and lights up with different brightness, depending on
the type of power supply:
green / red dark
>
power supply via battery
green / red light
>
power supply via phantom power on both outputs
green light
>
power supply via phantom power of OUTPUT 1
red light
>
power supply via phantom power of OUTPUT 2
• Adjust the input sensitivity of the DI box to the output level of your source device using the
ATTENUATOR (2) switch:
Switch not pressed
>
0 dB (no attenuation of the signal)
Button pressed
>
-30 dB (attenuation of the signal)
• Should faults due to ground loops occur during the audio transmission, press the GND (1)
switch. In the GND position, the signal ground is connected to the ground of the output signal,
whereas in the LIFT position, the signal ground is separated from the ground of the output
signal.
Maintenance and Cleaning
Please use a soft, dry, clean cloth for cleaning.
Do not use any chemical cleaning agents, as they can discolour the surface
fi
nish of the casing.
Disposal
Electronic devices are recyclable waste materials and must not be disposed of in
the household waste!
Dispose of an unserviceable product in accordance with the relevant statutory
regulations.
Remove the battery if there is one inserted and dispose of it separately from the
product.
Disposal of used batteries/rechargeable batteries
As the end user, you are required by law (Battery Ordinance) to return all used
batteries/rechargeable batteries; disposal of them in the household waste is pro-
hibited.
Batteries/rechargeable batteries contain harmful materials and are labelled with
the symbol shown to indicate that disposal in the household waste is forbidden.
The symbols of the relevant heavy metals are: Cd = Cadmium, Hg = Mercury, Pb =
Lead. You can return your used batteries/rechargeable batteries free of charge to
the of
fi
cial collection points in your municipality, in our stores, or anywhere where
batteries or rechargeable batteries are sold.
You thereby ful
fi
l your statutory obligations and contribute to the protection of the environment.
