A. Important
A1. Precautions
!Keep the preamplier away from high humidity, vibration, excessive dust and direct sun-
light. Exceeding heat or cold will aect the preamplier´s functionality.
!The permitted operating temperature is between 10°C up to 40°C (50°F up to 104°F).
Avoid extreme dierences in temperature.
!Do not operate the preamplier near other electric appliances (e.g. neon light, motors).
!Do not connect any musical instruments to the preamplier. This can result in irrepara-
ble damage to the equipment.
!Do not operate the device under condensation! Allow the preamplier to warm up to
room temperature for at least 3 hours after it has been exposed to low temperatures.
!Make sure the preamplier is never exposed to water or other uids.
!Never connect your preamplier to the outlet with an inadequate voltage setting, this
will result in heavy damage!
!The preamplier should not be opened without the assistance of a qualied technician!
A2. Safety
Your MC component complies with the household power and safety requirements in your area.
A3. Warranty
Please pay attention to the details on the warranty card which accompanies the unit. You
can also nd our warranty details on our homepage music-culture.com/warranty.
Warranty is only issued if you send back the warranty card.

B. General
B1. Scope of Delivery
The following components are included in your delivery:
mc 611 preamplier
A/C power cord
MC system remote control
B2. Placement
Make sure to leave a minimum space of 2 cm
(approx. 1”) on all sides of the preamplier to
allow heat to escape.
Never completely cover the preamplier during
operation!
B3. Maintenance
Unplug the unit before cleaning!
To clean the exterior surfaces of your MC preamplier, use a dry, soft cloth. To remove
nger prints and other grease spots use a soft cloth moistened with a mild detergent dis-
solved in water.
The cloth must never be dripping wet! If water or other uids enter the cabinet, you risk
to damage the preamplier.
Never use scouring pads, steel wool, scouring powders or harsh chemical agents, alcohol,
thinners, benzine, insecticide or other volatile substances, as these will destroy the nish
of the cabinet.

C. Installation
C1. Outputs (connecting power ampliers)
Your preamplier features two output groups to
connect up to 4 power ampliers in stereo or mono
mode. For stereo connection choose RCA cables, for
mono connection XLR (balanced) cables.
On the back of the preamplier you will nd the re-
spective output groups. The connectors are labeld
with Lfor left and R for right channel, as well as
tagged black and red, OUT1 and OUT2 for RCA.

C3. Optional inputs
Optionally, you can upgrade your mc 611 preampli-
er with two additional inputs for RCA or XLR connec-
tors. The panels for the optional inputs are located
on the back of the preamplier.
The additional XLR input allows you to connect one
more balanced source.
The additional RCA input allows you to connect
one more unbalanced source (e.g. CD direct, phono
MM/MC.)
C4. RS232 port
Your preamplier is equipped with an automation control sys-
tem. It allows you to expand any automation such as IR, RS232
or LAN. In the future even environment control will be possible.
You will nd the RS232 port on the right side of the back of your
preamplier.
C5. Ground connector (GND)
If you want to connect a ground wire (e.g. from your turntable) to
the preamplier, you will nd the ground connector on the left
side of the back of the preamplier.

C6. Connection to the outlet
On the back of your preamplier you will nd the connector for
the outlet. Use the included A/C power cord to connect your
preamplier to the main socket.
C7. Power on/o
To bring your preamplier to life, set the green power switch
on the back to position 1.
D. Operation
D1. Standby on/o
To switch from standby to operation mode push the
power button on the left side of the preamplier’s
front. Push it again to switch back to standby mode.

D7. In- and output level adjustment
On the top of the preamplier you can nd the level
adjusts.
With the input level adjustment you can decrease
each input signal by up to 12 dB. This way you can im-
prove sound by preventing volume peaks when you
switch between your music sources.
The output level adjustment allows you to adapt
the stereo balance to the acoustic conditions of the
environment. You can de- or increase the signals of
each channel and output group separately by up 6 dB.

E. mc 611 Features
E1. Modules
We only use selected high quality modules to build our MC Reference Line preamplier.
These modules play an important part in our preamplier's miracle of sound – and they
truly look amazing.
But please don’t open the preamplier’s cabinet without the assistance of an expert!
Switching standby module
The switching standby module comes with a shield-
ed design for the circuit switching. It ensures that
no magnetic eld or digital noise will come out of
the box. It also prevents any electrical or physical
interferences.
Power supply stage module
The power supply stage module oers an individual
power supply for the amplier section to guaran-
tee that enough electricity is available at any time.
This way the amplier section remains unaected
by the other sections and keeps the sound signal
in perfect condition.
Audio balanced-In module
The audio balanced-In module provides a high qual-
ity connection which ensures an outstanding per-
formance of your balanced music sources.
mc 611 preamplier
15 back to TOC 

Audio output module
The audio output module features a special circuit
design which keeps the output signal in a stable
and smooth condition. The signal will not be aect-
ed by other loading or output applications.
Fully shielded signal cables
We used fully shielded signal cables for the signal
paths. They prevent signals from reaching the
path. This way every signal stays in its original con-
dition to ensure pure signal movement inside the
preamplier.
