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,

Stacking several M219s

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.

SPEAKERS  
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.

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

others are transferred on to the

A 3-core cable with screening  
is recommended. In this case,

[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 (10k) 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.
