PLEASE READ THIS MANUAL CAREFULLY!
Positioning
Position Boazu on a flat, rigid surface with some space around
it, so that air can circulate. The rubber feet may appear simple
in construction, but are in fact carefully chosen for optimal
performance. Tighten them using your fingers only. Never
stack units on top of each other, as the feet can leave
permanent marks on the bottom unit!
Connecting (always done when switched off)
Connect your sources, one channel at a time, to the rear
connectors labelled ANALOGUE INPUTS. There are four
inputs per channel and they are always on. This means that it
doesn’t matter which connector you choose. If several sources
play, Boazu will mix them and play them through the
loudspeakers. This is simpler to use and in addition musically
superior to ordinary input switches if you are using less than
three sources.
Connect your loudspeakers to the speaker outputs, using a
cable terminated with Lejonklou 4 mm safety connectors.
Warning: Although individual banana connectors are possible
to fit, they are illegal to use in the EU for safety reasons. Use
only Lejonklou 4 mm safety connectors!
For optimal sound quality, we recommend single wire
loudspeaker cable. Lejonklou offers optimal loudspeaker cables
in custom lengths, using the best parts we’re able to find.
Please contact us if you need a pair.
When all connections have been made, you can connect the
power cord and switch Boazu on. A slight “thud” in the
loudspeakers is normal. In order to save energy, we
recommend Boazu to be switched off, using the rear mains
switch, when not in use for a longer period of time.
Protection – important!
Two circuits protect Boazu from internal overheating:
1: If the power supplies are heated above 50°C, they will
gradually derate their output in order not to overheat.
2: If continuous over current occurs, the output is limited.
But Boazu can easily be damaged by improper use:
One way is to short the speaker output terminals while the
amplifier is in operation. Protecting Boazu against a sudden
short circuit is not possible without loss of sound quality.
Therefore such protection was intentionally omitted. In
addition, no such protection circuitry is 100% effective.
Therefore: Never short the speaker outputs!
A second way to damage Boazu is to increase the volume far
above the point where the sound clips and distorts. This can
result in the output stage oscillating and destroying itself.
Please note that such volume levels can damage your
Boazu regardless of whether loudspeakers are connected
or not!
With many digital sources, volume 78 is where Boazu starts
clipping. This is also the standard volume limit, which is
possible to override in the user settings.
Not paying attention to the above precautions can damage
both your Boazu and your loudspeakers!
Lejonklou will not be held responsible for any speaker damage
due to a Boazu being short circuited or driven beyond its
capabilities.
We hope you will enjoy your Boazu!
If you have any questions, suggestions or encounter a problem
with it, please contact your retailer or Lejonklou directly.
