General
You should avoid installing it in
locations where:
The M219 is a digital Additional
Room Amplifier from the newest
M Series in the REVOX Multiroom
programme. It is used for the
reproduction of music in the
additional rooms in a Multiroom
system and can also supply the
listener with current information
through an additional display.
The M219 receives the signals
from a selected source (CD,
Tuner, Server ...) in the main
room through a multiroom bus
cable. Volume, balance, bass
and treble settings can be made
in individually in each room.
Also, up to 3 local sources can
be connected and listened to in
each additional room. If you
want “concealed” operation,

Re:connect
(2) PRE OUT
Two operating modes are possible with the M219’s preamp output:
Floating Volume (Factory setting from serial # 2000):
This is the standard mode setting. In this case, the PRE OUT level
changes parallel to the speaker level. This means that as you increase
the volume at the speakers, for example, the PRE OUT level is
automatically changed at the same time.
Application: You should select Floating Volume mode if, for example,
and additional output device or an active subwoofer is
connected, whose volume should also be controlled by
the M219. This means that the M219 speaker output
remains active.
Fixed Volume:
In this mode, the volume control and the M219 output devices are
deactivated, i.e. the volume cannot be controlled by any wall-mounted
or infrared remote control. The speakers connected to the M219 remain
silent. Irrespective of whether it is addressed through the multiroom bus
or a local input (Local IN 1 2 3), each source has a standard level, the
so-called Line Level.
Application: The Fixed Volume mode has been conceived principally
for applications where digital REVOX speakers are to be
connected to the M219 over a DLC2 interface.

Re:connect
(3) Voltage input IN (from serial # 2000)
Using the voltage input IN on the M219, the local audio input LOCAL
IN 1 can be activated by the application of 5 – 24 VDC. This means that
as soon as the voltage is present at IN, the M219 switches on
automatically and selects the input LOCAL IN 1. When the voltage is
removed from input IN, the M219 switches off again automatically, as
long as no other source apart from LOCAL IN 1 was addressed.
With DIL switch (3), you can define whether the volume control is
handled by the M219 (Floating Volume) or the connected (TV) device
(Fixed Volume). With Fixed Volume, the M219’s volume control is
deactivated and the audio signal at LOCAL IN 1 is transmitted with a
fixed strength. In this way, volume control is carried out with the TV
remote control.
The volume control setting set by DIL switch 3 only has an effect on the
local audio input LOCAL IN 1. All other sources are unaffected and
operate normally.

Application: Many devices output a voltage as soon as they are
switched on. If you connect the voltage output of such a
device with the IN voltage input on the M219 and the
audio output with the local audio input LOCAL IN 1, the
M219 will switch on automatically with the other device
and transmit the sound.
If your device doesn’t have a voltage output, you can
supply voltage to the input using a sensor-switch multiple
socket outlet (Master/Slave socket outlet) and a normal
plug-in power supply (5-24 V= / DC). Please refer to the
diagram on Page 11.

Please note: SCART sockets
Many devices such as SAT receivers, video recorders or DVD
players output a switching voltage through the SCART socket as
soon as they are switched on.
On a standard SCART socket, PIN 8 outputs the positive voltage (+)
and PIN 4 or 14 is the earth (-).
L
The principle of Master/Slave socket outlets
With this type of socket outlets, the control device (the TV in the above
example) is plugged into the master socket while all other devices are
connected through the slave sockets. As long as the master device is not
switched on, all slave sockets remain switched off. Once the master device is
switched on, all the slave sockets (the plug-in power supply in the above
example) are switched on at the same time.
In this way, you can “upgrade” any type of device to give it a switching-
voltage output.

M219 addressing
If you want to control each M219 individually, to use the alarm function of
the M51 Timer, for example, it is necessary to assign each M219 its own
address. The maximum number of M219s is limited to 8 per zone.
All M219s must have different addresses within one zone as otherwise
there may be communication problems.
The revisal of a correct addressing is made in the Setup menu of the
M51, category Multiroom / Version. All attached devices (M219 and/or
M217) must be listed in the respective zone.

Connection for IR receiver or
wall-mounted remote control
M217- Display connection
The external display M217 can
be connected to the M219-Link
connector, which can give the
listener basic information about
the current music programme.
If it is not possible or not
required that the M219 is
controlled directly with a remote
control, a wall-mounted remote
controller (e.g. M218) or and
external IR eye (MR-204) can
be connected to the IR-LINK
connector.
Connection to the IR receiver or
the wall-mounted remote
controller is made using a
screwable Phoenix plug
connector.
Connection is made using a
straight through (not crossed),
4-core telephone cable with an
RJ11 plug (6P4C-Modular)
connected to the M219 LINK
socket.

REVOX recommends the use of a

The M219 accepts all RC5 or

those that are intended for it. All
others are transferred on to the
Multiroom central unit.
A 3-core cable with screening

no further cable would be
necessary if you added an
additional display at a later
stage.

Re:connect
[6] IN Voltage input (from serial # 2000)
Using the voltage input IN on the M219, the local audio input LOCAL IN
1 can be activated by the application of 5 – 24 VDC. This means that as
soon as the voltage is present at IN, the M219 switches automatically to
LOCAL IN 1, irrespective of which source had been selected previously.
For further information please refer to DIL switch (3) / Page 10.
Please note:
The voltage input IN is galvanically isolated from the M219 with a
high-resistance (10kΩ) optical coupler. This stops any disturbances
from either side having any effect.
[7] CHANNEL SELECT
Stereo/ Mono switch
Using the Channel Select switch, you can adjust the operating mode of
the two music (stereo) channels, to the requirements of the room where
the M219 is installed. Three operating modes are available:
1) Stereo
The left music channel is reproduces through the left speaker
connector and the right channel through the right connector.
2) Inverse stereo
After installation, it can occur that the left and right speaker
connections have been inverted or that the sound picture is not
correct for the normal listening position. In this case, a quick
solution is offered with the Inverse stereo operating mode, which
inverse the assignment of the left and right speaker connectors.
3) Mono
If only one speaker is connected to the M219, or if the M219 is
controlling two speakers, each in a different room, you should select
the Mono operating mode. This means that each speaker receives
all the music information.
The configuration of the Channel Select switches is described on the
next page.

FUSE
Fuse
Speaker connection
Always power the unit down
before replacing the fuse.
Always use a cable of a
sufficient diameter for
connecting your speakers to the
M219.
When replacing the fuse, always
one of the same type as shown
on the M219 rating label.
REVOX recommends:
up to 15 m:
up to 30 m:
over 30 m:
Ø 1.50 mm2
Ø 2.50 mm2
Ø 4.00 mm2
Other fuse types with
different power, voltage or
operational characteristics
can endanger your life and
damage the unit.
We recommend not to use
cables longer than 50, due to
the unavoidable loss of HiFi
reproduction.
The fuse holder can be
removed by pushing it in slightly
and then turning it in the
direction of the arrow.
Each individual speaker must
have an impedance of 4 Ω or
higher. You must ensure that all
cable strands are within the
screwable Phoenix connector
and that none of them come
into contact with any adjacent
connectors or the M219
[12]
AC-POWER
housing.
Power connection
You will only be assured of a
perfect stage-quality
reproduction if you ensure
correct polarity when
connecting. A wrong polarity will
not cause any damage to the
speaker or to the M219, but it
can result in imprecise and
diffused reproduction that is
weak in the base ranges.
Only use the REVOX power
cable supplied. You must also
ensure that the power supply
used delivers the voltage as
shown on the M219 rating label
(240V). If required, the M219
can be modified to work with
other voltages. This
modification should only be
carried out by an authorised
specialist.
