FM Tuner 

Revox’s long tradition in Tuner 

development has reached a new 

high point. 

With the M51's modular RDS 

Tuner, every cable user can 

enjoy an optimum reception with 

incredible sound quality. 

Of course, this RDS Tuner offers 

you automatic station 

identification as well as 

Radiotext. 

Important for all Multiroom 

customers 

The Slave tuner, first introduced in 

2004 is a pure software innovation, 

which means that all M51 users 

can take advantage of it. You will 

find more details on this topic 

starting from Page 18. 

Features 

As well as striving for the 

optimum reception quality, an 

important development priority 

was comfort of operation for the 

user. The philosophy can no 

longer be: 

"Designed by engineers for 

engineers"“ 

but: 

"Designed by engineers for 

customers" 

This goal will accompany you all 

the time as you learn about your 

Revox Tuner. In spite of the 

simplicity and reliability of the 

operation, you shouldn't just put 

this manual to one side and rely 

on your intuition. 

There maybe some surprises in 

store.

Installation 

The Tuner plug-in card has the 

most modern technology on it 

and should be handled with 

care. 

Before you start to install the 

card, the M51 must be switched 

off and the power plug must be 

removed from the power socket. 

Any plug position can be 

selected for the module, with 

the exception of Slots 3 which is 

reserved for the Decoder 

module. 

Loosen the two screws with the 

TORX screwdriver supplied and 

remove the slot blanking plate. 

Before removing the Tuner 

module from its packaging, 

make sure that you are not 

charged with any static 

electricity. This could cause a 

damaging power discharge 

when you touch the module. 

To be on the safe side, you 

should discharge any static 

from yourself by touching an 

earthed metal object such as a 

radiator. 

Remove the Tuner module from 

its packaging and insert it into 

the slot position, using the two 

tracks within the M51 to guide it 

into position. The lettering on 

the card must be at the top. Just 

before the card is fully inserted, 

you will feel a certain 

mechanical resistance as the 

card meets the M51 contact 

strip. Push the card fully home 

by pushing in the area where 

the 2 screw holes are located 

and fix it in place with the two 

screws. 

All further steps needed to 

integrate the new module into 

the M51 will be carried out 

automatically next time the unit 

is switched on.

Connections 

REVOX 

ANTENNA 

INPUT 75 OHMS 

Connect the aerial socket to the 

rear side of the Tuner module, 

using a 75 Ω aerial cable. 

The tuner signal can either be 

received through a roof 

mounted aerial with aerial 

amplifier or by connecting to a 

cable network. 

We do not recommend the use 

of a room aerial.

Tuner menu 

Tuner operation 

The Tuner is accessed from the 

Source menu which is called by 

pressing the Source button on 

the front of the M51. The 

following display appears and 

you can activate Tuner 

reception by pressing the FM 

Tuner softkey. 

The first time you set the Tuner 

up the Tuner menu appears 

with the following display, after 

pressing the FM Tuner softkey 

in the SOURCE menu. 

 

The five large buttons on the 

front of the M51 are shown as 

If the Tuner has already been in 

operation and stations have 

been stored, the following 

display appears after pressing 

the FM Tuner softkey in the 

SOURCE menu. 

Setup Source Amplifier 

Power Disc 

in the following chapters.

Station searching 

The Tuner Setup menu offers 

you three alternatives for 

searching for and storing 

stations. 

You address the Tuner setup by 

pressing and holding the Setup 

button on the front of the M51 

for approx. 2 seconds and then 

pressing the Source softkey. 

The following display appears: 


1) Manual station search 

With Search, you set stations 

up manually 

Press the Search softkey and 

select the required frequency 

using the rotary control knob. 

[ ] 

The little dial in the middle of 

the display shows the strength 

of the station. 

Please note 

When ever you can change a 

setting using the rotary control 

knob in the next section, the 

area to be modified appears in 

the display between two square 

brackets [...]. 

At the same time, the small red 

Jog light next to the knob on 

the M51 lights up. 

If an RDS signal is received, the 

station name appears in the 

display after a little delay. 

The manual highlights this 

additionally in the individual 

sections, with the following 

symbol: 

[ ]

Storing stations 

Add function 

With the Add and Store 

softkeys, you have two different 

ways of storing a new station. 

These functions are called from 

the Tuner Setup menu. 

With the command Add, a 

station will be stored on a new 

station key, with the next 

highest number. 

Using this function, you remain 

in the Setup menu and can 

scan for and store more 

stations. 

A maximum of 50 stations can 

be stored. 

If you want to return to the 

Tuner menu, simply press the 

Source button twice. 

Example 

If you have already stored 4 

stations, key 5 will be added 

with the Add function and the 

station will be stored there. 

7



Store function 

2) Station scan 

Using the command Store, a 

new station can be stored at the 

position which was being used 

before the manual frequency 

change was carried out. 

Using the Scan function, 

you can scan for stations with 

ascending or descending 

frequencies. 

This option returns you to the 

Tuner menu after storing the 

station. 

A maximum of 50 stations can 

be stored. 

Example 

You have stored a station with 

the frequency 93.5 MHz at 

position 3 and using i.e. the 

search command to change to 

95.0 MHz. If you then press 

Store, Position 3 will then have 

95.0 MHz stored on it. 

With Scan you will scan 

upwards through the range and 

with Scan you will scan 

downwards through the range, 

until the required station is 

found. 

This function is called through 

the Tuner Setup menu. 

If you are happy with the choice 

of station, you can store it using 

the Add or Store functions 

described in the Storing 

stations section. 

8



3) Full automatic station scan 

The Automem function scans 

for all available stations and 

then stores automatically in 

ascending frequency order. 

Automem was especially 

developed for use with systems 

that are connected to a cable 

network. In this case, there are 

so many stations offering 

optimum transmission 

performance that it would be 

very time intensive to manually 

search for and store all the 

stations. Automem can store a 

maximum of 50 stations. 

Automem is not suitable for 

use with room aerials because 

as a rule, these pick up too 

many interference signals which 

are recognised as stations and 

then stored. 

Automem 

You address this function by 

pressing the Setup button for 

approx. 2 seconds while you 

are in Tuner operation and then 

pressing the Source softkey. By 

pressing the More softkey in the 

Tuner Setup menu, you will get 

to the second page where the 

Automem softkey is located. 

One of the two following 

displays appears, depending on 

whether the Tuner has been in 

operation or not. 

Press and hold the Automem 

softkey for approx. 5 seconds. 

The Timer now automatically 

starts to scan for and store 

stations. 

While the Tuner is scanning, the 

word Automem flashes in the 

display. 

Once all stations have been 

stored, the station stored at 

position 1 will start to be played. 

9



Mono operation 

A lot of background noise is 

generated with many stations 

with a weak signal. This can be 

significantly reduced by 

switching from stereo to mono 

operation. 

If you want to switch to mono 

operation, press and hold the 

Setup button for approx. 2 

seconds until the following 

display appears. 

Press the Source softkey to get 

to the Tuner Setup menu. 

You can toggle between stereo 

and mono operation by pressing 

the Mono softkey. Press it once 

in stereo mode to switch to 

mono and vice-versa. 

The following display shows the 

station Antenne 1 in mono 

operation. 

If you want to get back to the 

Tuner menu, simply press the 

Source button twice. Mono 

operation is maintained until 

you change source or station. 

If you want the mono setting to 

be stored permanently, the 

station must be stored again as 

described in the Storing 

stations section. 

10


Select stored station 

To select a stored station, 

simply press the softkey 

assigned to the position where 

the station is stored. If more 

than 6 stations have been 

stored, these are to be found on 

further station pages. 

As up to 50 stations can be 

stored, there can be a 

maximum of 9 pages. You can 

scroll through the various pages 

with the More and Back keys. 

This is a continuous loop so 

when you reach the last page, 

More will take you back to the 

first page. 

Edit station names 


The Edit Name function 

enables you to change the 

names assigned to the stations 

retrospectively to your own 

requirements. This is 

particularly useful if the station 

doesn't transmit any RDS signal 

or if you simply want to change 

the name to one of your own 

personal choice. 

From the Tuner menu, choose 

the station whose name you 

want to change. 

You call this function by 


approx. 2 seconds and then 




to the following menu: 

11


Edit function 

You will move to the following 

menu display by pressing the 

Edit Name softkey. 

The following Edit functions are 

available: 


Edit characters [ ] 

The actual modification of the 

individual characters (letters 

and digits) is done through the 

rotary control knob. When you 

turn the knob, upper case 

letters appear in alphabetical 

order, followed by lower case 

and then the digits from 0 - 9. 

This order can be reversed by 

turning the knob in the opposite 

direction. 

Character order: 

The softkey Cursor moves 

the [ ] cursor to the left. 

The softkey Cursor moves 

the [ ] cursor to the right. 

The softkey Delete deletes the 

cursor at the current [ ] cursor 

position. 

The softkey Insert inserts a 

character to the left of the 

[ ] cursor. 

The softkey Store saves the 

currently displayed name and 

returns you to the Tuner menu. 

The softkey Cancel returns 

you to the Tuner menu without 

saving any modifications made. 

... _ A B ... 

... X Y Z ... 

... a b c ... 

... x y z ... 

... 0 1 2 ... 

... 8 9 _ ... 

Once the required source name 

has been selected in this way, it 

can be saved with the Store 

softkey. 

If you want to exit without 

saving, press the Cancel 

softkey.

RDS equipment 

Update station names 


The FM Tuner module from 

REVOX is equipped with very 

effective RDS identification. 

 

RDS = Radio Data System 

With RDS, the radio station 

sends the station name with 

some additional Radiotext in 

some cases, alongside the 

audio signal. 

This allows the FM Tuner to 

recognize which station is being 

received automatically. As well 

as the station name, additional 

Radiotext appear sporadically in 

the display. This gives you 

information about the current 

artist, track, etc. 

It can occur that some stations 

play the Radiotext in the same 

field as the station name. This is 

quite normal and does not 

indicate a fault in the FM Tuner 

module. 

With the two scan options of 

Automem and Scan, it can 

happen that at the time the 

station is being stored, no RDS 

signal was available or the 

stations was using the station 

name field for Radiotext. In this 

case, the Tuner wouldn't store 

the actual station name but just 

its frequency or some Radiotext. 

To avoid the entering of the 

station names by hand 

afterwards, the Tuner module 

offers the Set Name function. 

In the above example, the 

station with the name Buy Now 

has been entered for the station 

stored on position 4. Proceed 

as follows to carry out an 

automatic correction of this 

name: 

13



From the Tuner menu, choose 

the station whose name you 

want to change. 








Wait a short time until the Tuner 

has identified and displayed the 

correct RDS name and then 

press the Set Name softkey. 

The correct name is now stored 

and you are returned 

automatically to the Tuner 

menu. 

If no RDS station name 

appears, this means that the 

station in question does not 

broadcast an RDS signal. In this 

case, you can enter a name of 

your choice using the Edit 

Name function. 

14



Move station 

Using the Move function, you 

can move stations which have 

already been stored to a 

different position. 

In this way, you can for 

example, move your six 

favourite stations to the first 

station page so that you don't 

have to scroll through the 

various pages. 








When you press the Move key, 

you will be returned to the 

Tuner menu and the flashing 

Move Fromsymbol in the 

display tells you that you can 

now select the required station 

position which you wish to 

move. 

In our example, you would now 

press the position 10, with the 

station name SWR3. 

Immediately, the display 

changes from showing 

Move Fromto showing 

Move Towhich shows you 

that you can now choose the 

position you wish to move to. 

In this example, the station 

SWR3 is at position 10. You 

would like to move it to 

position 3. 

If this is not on the current page, 

you can scroll to the correct 

page with Back or More. 

15



Continuing with our example, 

you would use the Back softkey 

to move to the first page which 

has positions 1 to 6 on it. Here 

you would press position 3 and 

SWR3 would be moved to 

position 3. 

All the stations on the following 

key positions are then move up 

by one. 

Once you have moved the 

station to the required position, 

the display changes back to 

flashing.: 

Move From 

and you can repeat the 

procedure as often as you 

need. 

Once you have completed your 

station moving, you can leave 

the Move function with the 

Source or Amplifier button. 

16



Delete station 

The Delete function deletes a 

station and fills the "hole" left by 

moving all following stations by 

one position. 








You can repeat this procedure 

as often as you want, until you 

have deleted all the unwanted 

stations. 

Once you have completed all 

the deletion you can leave the 

Delete function with the Source 

or Amplifier button. 

 

If you press the Source button 

twice, you will return direct to 

the Tuner Main menu. 

When you press the Delete key, 

you will be returned to the 

Tuner menu and the flashing 

Deletesymbol in the display 

tells you that by simply pressing 

the corresponding key, the 

corresponding station will be 

deleted. 

17



Additional Tuner – Slave tuner 

General 

In Multiroom operation, there is 

the situation that several people 

want to listen to the radio at the 

same time. If only one tuner is 

installed in the M51, only one 

common station can be listened 

to. 

Now, through the installation of 

additional, so called Slave 

tuners into the M51, REVOX 

offers the option of assigning 

one or more additional room 

zones their own tuner. 

The slave tuner only differs from 

the main tuner through its 

software. The tuner module 

itself is identical. 

The number of slave tuners 

depends on how many 

additional room zones should 

be assigned their own tuner. 

The table below shows where 

and how many slave tuners are 

used in order to equip the 

required zone(s) with their own 

tuner. The plus (+) character 

indicates that these zones will 

use a common tuner. 

Note: 

Zone 1 and the Main room 

always share the same main 

tuner.

Version control 

You can check whether the 

slave tuners have been 

correctly logged by the system 

using the M51 version control 

function. 

To call the Version function, 

press the Setup button for 

about 2 seconds and the 

following menu appears. Please 

also refer to chapter 

Introduction/Software version 

Press the version softkey and 

the Version window opens up. 

Operation 

The operation of an M51 with 

integrated slave tuners does not 

change. As before, only one 

tuner (main tuner) is shown in 

the Source menu display. Slave 

tuners are not shown. 

You operate the tuner as 

described in the Tuner 

operation chapter from page 5. 

All changes, e.g. a resorting of 

the programme stations at the 

main tuner will also be applied 

in the background to the slave 

tuners. This means that you 

always have identical slave 

tuners in the zones. 

Because of this, operation in the 

additional rooms also doesn’t 

change. Now however, you can 

receive different programmes in 

the individual zones. 

The above example shows a 

single slave tuner operation 

where a slave tuner 

(#2 FMS-1 1.20) has been 

added in addition to the main 

tuner (#1 FMT-1 1.20) 

This slave tuner (FMS...) serves 

zones 2+3+4 (see Tuner zone 

assignment table on page 18).
