Installation
In this chapter you’ll learn more about the connections, controls
and possible applications of your Lehmannaudio Drachenfels
headphone amplifier.
1 | Unpacking
After unpacking the Drachenfels check it for possible transport damages. If you
notice visible damages, you must by no means connect the device to mains. In
this case consult your dealer immediately.
The delivery comprises the following components:
≠
Drachenfels unit
≠
Power supply with matching primary adapter
≠
User manual
≠
Guarantee voucher
Note
We recommend keeping the entire packaging for later shipment.
That way you will avoid transport damages. Use by no means
‘foam chips’ or similar packaging material. Otherwise the device
will jolt through to the bottom of the cardboard box during
transport and can be damaged!
If the original packaging is no longer available, it’s best to use
bubble wrap in which to wrap up the device in a generous man-
ner. Finally the whole should be put into a solid cardboard box.
