G.F. HÄNDEL is a linear class A amplifier
delivering superiority and authority not to be
found in lesser creations due to the high current
capability and operating speed. lever
construction techniques enabled us to build an
amplifier with high packing density,
consequently making the signal and power
paths extremely short.

4
Room temperatures over 30 degrees elsius
and / or extreme humidity should be
avoided. Keep away from heat sources like
radiators, heating, ovens or similar
appliances dissipating heat. It is important to
maintain an adequate supply of airflow to
prevent overheating.
!
Place the unit(s) on a solid, flat level surface such
as a shelf or directly on the floor. Virtually, there
are no limitations on where to position your G.F.
HÄNDEL. We suggest positioning the unit(s) so
that the speaker connecting cables remain
short.
First, establish the A – power connection. The
IE mains input is located on the rear panel.
Make sure that the A mains switch is set to (0) =
OFF. onnect the power cord to the IE mains
input and plug it into your wall outlet or high
quality power strip.
G.F. HÄNDEL offers a balanced input, because a
properly implemented balanced connection
will offer higher sound quality than a single-
ended connection. The amplifier can be driven
by a preamplifier or directly from a line – level
source that has a volume control.

5
onnect your loudspeakers to the amplifier. The
speaker cable can be connected via spade
plugs or via banana plugs. Avoid speaker
cables with excessive capacitance. As with any
other high speed amplifier, such cables can
lead to instability. If in doubt, please consult your
speaker cable manufacturer. Now, before
turning the amplifier on, make sure that all
cables have been connected firmly and in
correct polarity.
Never attempt to ground the negative
binding post, as this is an active output.
Doing so will short one half of the amplifier
and damage may occur. !
Operation
With the speakers and the source connected,
switch the rear mains switch to (1) = ON and
press the front panel push button to activate the
amplifier. The blue LED will come on. After
switching to operating mode the protective
circuits take 10s to check all circuits of the power
amplifier before enabling the speaker outputs.
There is no need to operate the mains ON / OFF
switch on the back side since the standby
power consumption is less than 0,5W. As it is
common practice, disconnect G.F. HÄNDEL from
the mains during a thunderstorm or when going
on vacation.

Protection circuits
HÄNDEL provides comprehensive protection for
both the amplifier and your loudspeakers,
including faults that may occur in your source
components.
If the unit is operated at high playback levels
with insufficient ventilation, the internal
temperature may become too high for safe
operation. In this case the front-panel status LED
will change colour from static blue to red. If the
LED is appears totally red, the amplifier will shut
down, the LED will blink until the unit has cooled
down sufficiently.
Likewise, if the surveillance circuit detects the
presence of D (LED = blinks green) at the output
terminal, the amplifier will shut down too.
Unallowable D voltages can origin from the
source component or the HÄNDEL amplifier itself.
To isolate the source of the problem, disconnect
the audio input cable from the HÄNDEL amplifier
before proceeding any further.
If the error message persists, the amplifier hasn’t
cooled down sufficiently, or the unit itself is faulty.
If the D error only shows up, when the source is
connected, the source component is faulty. In
both cases consult your dealer.

7
An overcurrent condition is monitored
permanently. If the output current to the
loudspeakers exceeds 50A the amplifier will shut
down immediately.
Mains voltage selection / fuse replacement
The following work should only be carried
out by a qualified technician in accordance
to highest electrical safety standards. Risk of
electric shock. !
Replacing the fuse
The fuse must be replaced by a 10AT type
(5x20mm). Never attempt to short the fuse
holder. Normally the fuse should never blow – if
it has, it is a sign of a serious fault condition.
Further investigation is needed.

E declaration of conformity
Product Type: Power amplifier
Model: HÄNDEL
Linnenberg-Elektronik declares that this product
complies with the Low Voltage Directive
2014/35/EU and the Electromagnetic
ompatibility Directive 2014/30/EU as well as the
Ecodesign Directive 2009/125/E .
The unit meets all currently valid regulations only
in its original condition. The original, unaltered
factory serial number must be present on the
outside of the unit and must be clearly legible!
The serial number is an essential part of our
conformity declaration and therefore of the
approval for operation of the HÄNDEL. The serial
numbers on the unit and in manual, must not
be removed or modified, and must correspond.
Furthermore, the unit has been found to comply
with the limits for a lass B digital device,
pursuant to Part 15, subpart B (unintentional
radiators) of the F rules.
