M51 - The concept
• Scalability
The M51
demands and requirements
grow. Using this modular
concept, you can build your
own personal M51. Simply
insert the required modules
into the corresponding slots
at the rear of the unit and
switch on.
• Future-secure
What type of signal
information will there be in
the future? It doesn't matter
because you'll always be up
to date. Revox will always
offer you new modules
based on cutting-edge
development technologies.
• Economics
We haven't forgotten the
economic and financial
aspects of the product
either. You just buy the
modules you need. There's
no component redundancy
and you don't have to pay
for anything you don't need.

What do I need to connect
Unit A to Unit B and are
they going to understand
each other? No worries for
an M51
connections are integrated
and each module "speaks
the same language".
• The aesthetics of
operation
Many tasks, just one
component. Just let your
imagination run free. The
M51
commands to the letter.
• Philosophy of Excellence
It's not only the accuracy of
our clocks which links the

Introduction Re:system M51 II
Getting started
Before you can enjoy your M51
for the first time, you'll need to
make a few connections.
Connections
Speaker Amplifier
The cable which you use to
connect your speakers with the
M51
should be of a suitable
diameter.
Revox recommends:
0 – 5 m length: min. 2.5 mm
( 13 AWG )
5 –10 m length: min. 4.0 mm
( 11 AWG )
Each speaker must have an
impedance of 4 Ω or more. You
must ensure that all the strands
of the cable are held within the
speaker connector and that
none of them touch any
neighbouring connectors or the
housing of the M51.
A good solution for speaker
connections is the use of fully
insulated banana plugs.
These are inserted into the
4 mm terminal block opening
having been firmly attached
beforehand.
2
2
You must be careful to keep the
correct polarity in order to
ensure perfect sound
reproduction. Crossed polarity
doesn't cause any damage to
the speaker or the M51, but it
leads to an imprecise bass and
a somewhat diffused sound
picture.
If you are not intending to attach
all 5 speakers, the other
terminal connections simply
remain unused.
Power cable
You should only use the Revox
supplied power cable and you
must ensure that the voltage
printed next to the power
connection i.e. (115V/230v) is
actually what the power supply
is delivering. If necessary, the
M51
can be retrofitted for a
different voltage, which should
only be carried out by an
authorized dealer.
Head phones
You will find the headphone
connection on the left at the
front of the unit. It can be used
with all normally available
headphones with a 6.3 mm
stereo jack plug and an
impedance of 16 Ω or more.

Introduction Re:system M51 II
M51 Link
The M51 offers a wide range of
useful and practical extension
products. These so-called
interfaces enable access to
other systems and/ or offer
many control and operational
comfort solutions, through the
M51 Link.
Here are some examples:
M200 / M200 EIB
Intelligent domestic building
management with relay and
dimmer functions as well as a
serial interface for PC and
Revox video products and
domestic Building Management
Systems such as EIB.
M201
IR Interface for the connection
of external IR receivers (M204)
or wall-mounted panels (M218).
M202
Ethernet Interface to integrate
the M51 and all the Additional
rooms into one network (LAN)
or for the addition of a wireless
control unit with Pocket PCs
(WLAN).
All these interfaces are
connected to the M51 Link,
which is located on the rear of
the M51 above the power plug
(see leaflet Chapter –
Introduction). You need an
RJ11-4 telephone plug for the
connection.
PC-Link
The PC Link offers a USB
interface for the computer.
Using this, the M51 can be
controlled through the M230
Revox PC Control software.
The correct USB driver must be
installed on the PC in order to
be able to use the M230
software, which can be
downloaded free-of-charge from
www.revox.de. You will also find
this driver software in the
Download Area on the Revos
Homepage.
The PC-Link is located on the
rear of the M51 above the
power plug (see leaflet Chapter
– Introduction).

Introduction Re:system M51 II
Headphone operation
Overheat protection
You will find the headphone
connection on the left at the
front of the unit. It can be used
with all normally available
headphones with a 6.3 mm
stereo jack plug and an
impedance of 16 Ω or more.
As soon as you plug your
headphones in, the external
speakers are switched off and a
headphone symbol appears in
the bottom line of the display.
(See below)
At the same time, the M51
switches automatically to Pure
Analog so that you always
have the optimum sound quality
when using your headphones.
When you remove the
headphone jack, the M51
reverts automatically to the
sound setting which was being
used before.
The M51 's power outputs are
fitted with an active temperature
sensor which is constantly
monitoring their temperature,
and if necessary activates a 3speed fan.
If the temperature should still
exceed the maximum permitted
level, the M51 switches the
outputs down to 25% of their
maximum power. This is shown
by the overheat symbol being
shown in the bottom line of the
display. (See below)
This power level will be maintained until the temperature
comes back down under the
permitted maximum value. After
this, the volume can be
increased again.
