4.2 Body support mounting
Take the body support from the transport bag of the instrument and insert their ends
into the openings provided on the side of the body.
Make sure that the curvature of the body support points to the rear and that it sits
tension-free on the body. Tighten the bracket screws by turning them clockwise.
4.3 Mounting the bridge
On delivery, the strings of the instrument have minimum string tension between the
machine heads and the tailpiece on the fretboard. Remove the cable tie that secures
the strings for transportation.
Place the bridge in the holder provided on the top of the instrument body and set
the desired height using the two screws.
NOTICE!
Possible deformation
When adjusting the height of the bridge, excessive pretension can over‐
stretch the strings or damage the bridge or the top of the body.
On excessive tension, reduce the pretension of the strings or the height
of the bridge to avoid damaging the strings, the bridge or the top of the
body.
Make sure that all strings run correctly in the grooves of the bridge (the E string has
to run in the biggest groove).
You can then tune all strings with the machine heads using a tuner device to the cor‐
rect pitch (usually E, A, D and G).

CAUTION!
Possible hearing damage
Using headphones for a prolonged period and at high volume can
cause hearing damage.
Avoid using the device at high volume, especially when using head‐
phones.
NOTICE!
Risk of breakage, possible deformation
When placing the instrument with the fretboard down, there is a risk of
damaging the ngerboard and the tailpiece.
Avoid any compressive load on the rear of the instrument, if it is placed
for the assembly or for service work with the fretboard down on a solid
surface.
Before connecting ampliers or headphones, the volume controls of the
cello and the equipment to be connected must be set to "minimum". This
avoids loud crack noises when switching on.
5.1 Connecting and inserting the battery
The instrument is operated with a 9 V block battery. The battery is not included in the
scope of delivery.
Open the battery compartment cover on the back of the instrument. Clamp the
power cable with the correct polarity to the battery. Insert the battery into the bat‐
tery compartment and close the battery compartment cover. It must audibly click
into position.

6 Maintenance
6.1 Changing strings
Strings are subject to a natural aging process, which is also aected by the frequency
of use of the instrument. Changing the strings is recommended if the sound quality
of the instrument decreases audibly. Always replace the complete set of strings
(strings of 3/4 length) and always go string by string. In this way you avoid a strong
temporary bending of the neck due to reduced string tension. The bridge also
remains in the correct position and does not have to be readjusted.
1. For example, loosen the run-down E string from the capstan of the machine
head and from the tailpiece.
2. Thread the new E string into the tailpiece, pull it over the bridge into the cap‐
stan bore of the machine head.
3. Hook the string end to the capstan and tighten the string tension slowly. At the
rst windings, pay particular attention that the string is taut to the mechanics.
4. Make sure that the string is running correctly through the grooves of bridge
and nut at the upper end of the neck.
5. Slowly increase the string tension until the correct pitch is reached. Use a tuner
or a pitch pipe for reference.
6. Proceed in the same way with the A, D and G strings and then tune all strings
again successively to the correct pitch. Note that the string tension will drop a
little and the instrument needs to be retuned several times until the strings
stay in tune.
6.2 Battery change
1. Replace the inserted battery if necessary (weak output signal) or at regular
intervals.
2. Open the battery compartment cover on the back of the instrument. Remove
the battery and unplug the connection cable from the battery terminals.
3. Clamp the power cable with the correct polarity to the new battery. Insert the
battery into the battery compartment and close the battery compartment
cover. It must audibly click into position.
NOTICE!
Risk of re due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.
Proceed as follows to change the
strings:

8 Plug and pin assignments
This chapter will help you select the right cables and plugs to connect your valuable
equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated:
Even if a plug ts into the socket, an incorrect connection may result in a destroyed
power amp, a short circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi
use. Instrument cables with two conductors (one core plus shielding) are typical rep‐
resentatives of the unbalanced transmission. One conductor is ground and shielding
while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at
low levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred,
because this enables an undisturbed transmission of signals over long distances. In
addition to the conductors ‘Ground’ and ‘Signal’, in a balanced transmission a second
core is added. This also transfers the signal, but phase-shifted by 180°.
Since the interference aects both cores equally, by subtracting the phase-shifted
signals, the interfering signal is completely neutralized. The result is a pure signal
without any noise interference.
