Assembling and tuning your instrument are described in detail in the following sec‐ tions.

4 Assembly instructions

Assembly instructions

4.1 Setting the height

The endpin to adjust the height of the instrument is fully retracted in delivery condi‐ tion and fixed with one wing nut.
Turn the wing nut counterclockwise to loosen the fixation and the endpin.

Drag out the endpin so far that the instrument can be played at the desired and for you ergonomically correct and comfortable height.
Then tighten the wing nut clockwise to fix the endpin in this position.

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).

4.4 Tuning the strings

Tune all strings with the pegs using a tuner device to the correct pitch (usually E-A-D

5 Connections and controls

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 fingerboard 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 amplifiers 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.

5.2 Connecting the instrument cable

The connector for the instrument cable (1/4″ jack, mono) is located on the back of the instrument.

5.3 Connecting audio devices

The [Mp3in] connection for audio devices (3.5 mm jack socket, stereo) is located at the side of the instrument body.

5.4 Connecting headphones

Connection [Phone] connection for headphones (3.5 mm jack socket, stereo) is located at the side of the instrument body.

5.5 Adjusting Volume and SubBass

The controls to adjust the [Volume] and [SubBass] are located at the side of the instru‐\ ment body

6 Maintenance

6.1 Changing strings

Strings are subject to a natural aging process, which is also affected 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.

Proceed as follows to change the strings:

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 first 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.

8 Plug and pin assignments

Introduction

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 fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or ‘just’ in poor transmission quality!

Balanced and unbalanced transmis‐ sion

Unbalanced transmission is mainly used in semi-professional environment and in hifi 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 affects 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.

9 Cleaning

Clean the instrument and especially the strings after playing with a dry, soft, lint-free cloth. Stubborn dirt can be removed with a slightly dampened cloth.
Never use cleaners containing alcohol or thinner.
