Connection and start-up
The mains socket to which the power supply unit is connected must be easily accessible,
so the device can be quickly isolated from the mains voltage in the event of a fault.
Be careful when handling mains cables and mains connectors. Mains voltage may cause
fatal electric shocks.
Switch off the devices to be connected before connecting them to the connection sock-
ets. Do not switch them on again until you have made all the necessary connections and
checked them.
• Connect the Line-output of your audio-device to the Line-input (3) of the headphones amplier.
• Line-signal will be looped through the Line-output (2) of the headphones amplier and can be connected
with another devices.
• Connect the casing to the mains voltage (1) via the mains unit included in the delivery. The LED (4) on the
front side of the device goes up.
• Turn all devices on.
• Before connecting of the headphones to headphones jacks (5) and (6) turn the VOLUME control (8) off (in
counter-clockwise direction).
• Headphones jacks (5) and (6) may be used simultaneously.
• Sound can be regulated with the NOTE control (7).
• Now set the desired volume, with the VOLUME control (8).
You can use both headphones jacks at the same time. Volume level may be different if different
headphones are used.
Use appropriate adapter by using of headphones with different connector.
To transmit audio signal of a TV-set, it must have a Line-audio-output or a SCART-port. For
SCART-port use an adaptor with an audio-output. When making your purchase, please take
note of the correct allocation (SCART -> Cinch). Better SCART-AV-Adaptor are switchable or
have 6 Cinch-connections (3 for in- and output).
Handling

The condensation that forms might damage the device.
Leave the device disconnected and wait until it has reached room temperature. Wait until the condensation
