Important Information!
Attention! Keep the preamplifier away from high humidity, vibration, excessive
dust and direct sunlight. Excessive heat or cold will aect the preamplifier´s
functionality. The permitted operating temperature is 10°C up to 40 °C (50°F
up to 104°F). Avoid extreme variations in temperature. Do not operate the pre-
amplifier near other electric appliances (for instance neon light and motors).
The preamplifier should not be opened without the assistance of a qualified
technician!
WARNING: Do not connect any musical instruments (e.g. electric guitar etc.) to
the pre-amplifier. This use for a purpose for which it is not designed – i.e. for a
purpose other than playback - can result in irreparable damage to the equip-
ment.
Do not operate the device under condensation! Allow the preamplifier to warm
up at least three hours to room temperature after it has been exposed to low
temperatures.
Make sure that no fluid-filled vessels (glasses,vases…) are put on the device to
prevent water from ingressing the device, and the device is never exposed to
splash water.
Please discard used batteries in accordance to your country´s laws.
KETI, CE-Marking
This product conforms to the requirements of the EMC directive and low-volt-
age directive. Your MBL component complies with the household power and
safety requirements in your area.
Warranty
Please pay attention to the details given in the warranty card which accompa-
nies the unit. Warranty is only issued, if you send back the warranty card.

1. Installation
1.1 General Precautions
Keep your preamplifier away from humid places. For example, do not operate the device near air dampeners or in
bathrooms. The relative humidity may be between 10% up to 90% in operation, as long as condensation does not
occur. As with any other electrical device, direct contact with water will not only damage the preamplifier but will
lead to a hazardous situation that will result in death or serious injury!
Excessive heat or cold will aect the unit’s functionality. Therefore, do not operate the unit near a heat source
such as a radiator and do not expose it to direct sunlight. The permitted operating temperature is 10°C up to 40 °C
(50°F up to 104°F), the storage temperature is between -10°C and 50°C (14°F and 122°F).
Condensation may emerge inside the device, if temperature changes excessively within a short time. In this case,
do not connect the device to the mains as this may result in a short-circuit, leading to malfunctions or damage.
If you, for example, transfer the unit from outside into a heated room in winter, wait at least three hours before
connecting and operating it. Store the device only in a place where the temperature and humidity are constant
as frequent condensation will harm the device. The environment should be free from dust or sources of electric
interference such as fluorescent tubes or engines.
Do not expose the device to heavy vibrations as this may lead to malfunctions or damages. Install the device in a
level and stable place. Please consider the heavy weight of MBL products!
1.2 Connection to the Outlet
Your preamplifier features two high-quality toroidal transformers for power supply. Depending on the setting, it
is proposed for the connection to the outlet providing either 230 V/50 Hz or 115 V/50/60 Hz. The device is shipped
with the voltage setting appropriate for the country where it is sold.
If you want to operate the device in a country with a dierent mains voltage, please contact a qualified technician
to have the operating voltage altered accordingly. For safety reasons, this can be achieved only after opening the
enclosure of the device. Further, the fuse must be replaced: A 0.63 amps sb fuse is required for an operating volt-
age of 230 V, a 1.25 amps sb fuse for 115 V.
Note: If you connect your preamplifier to the outlet with an inadequate voltage setting, it will result in heavy dam-
age. MBL assumes no responsibility for accidents and damages caused by improper settings. Further, changes
made to the voltage setting by a technician will not be covered by the warranty either.
Caution! Whoever opens an electric device without previously disconnecting it from the outlet puts his life at risk
carelessly and irresponsibly. Unplug the unit before opening!

2. Connecting Other Components
2.1 Outputs
The mbl 6010 D is designed for connecting one or more power amplifiers. It provides the following analog outputs
for power amplifier connection:
OUTPUT GROUP 2 OUTPUT GROUP 1
2 x RCA outputs (21 and 22) per channel 2 x RCA outputs (11 and 12) per channel
1 x balanced XLR output (23) per channel 1 x balanced XLR output (13) per channel
2.2 Inputs
Up to 7 source devices can be connected to your mbl 6010 D. For this purpose, it provides the following analog
inputs:
OPTION 1 | OPTION 2 CD 1 | CD 2 | TUNER TAPE 1 TAPE 2 PROCESSOR
The inputs OPT 1 and OPT 2 are optional inputs reserved for additional modules such as Phono MC or balanced
input. OPT 1 is already equipped with a balanced input.

3. Front Panel Controls
3.1 Input Selector
With the input selector switch you can select one of the various sources connected to the preamplifier. The pro-
cessor enables the connection of an extern surround-decoder. Choosing this input will engage a signal to the con-
nected amplifier (Bypass). This gives the possibility to switch between audio (music replay) and video (DVD). Use
buttons Opt 1A / Opt 1B / Opt 2 and to select plugged in Phono MC or Balanced-In modules.
Input selector settings:

3.2 Input Section
The input section is composed of level encoders and record buttons.
Record selector
With the record select buttons the signal source for a connected tape machine can be controlled. The recording
procedure can be performed independently of playback; for example, the tuner can be routed to the output using
the input control while a tape recording is being performed from CD. The recording quality can be checked im-
mediately during the recording process; for this purpose, set the Input control to Tape 1 or Tape 2. (Tape 1 refers
to the machine connected to the TAPE 1 connector and Tape 2 to the device connected to the TAPE 2 connector).
Input level unit
The precision potentiometers are associated with the respective inputs and provide input-signal attenuation by up
to 12 dB in order to prevent volume peaks when changing between sources.
