Description
The DMM 4650 is a signal processor, allowing an universal generation and
control of audio signals. The main application is for PA racks, but stand-
alone applications are possible as well. The audio signals can consist of
alarm, gong, messages and also random combinations. These programs
were created by Dynacord and stored as presets.
The audio quality of the messages can be selected depending on memory
extension and different user requirements. With maximum memory exten-
sion, a total recording time of 16 minutes is possible. Password protection
is provided. The operation is easy, like cassette recorders or CD players.
A computer interface allows saving and loading of unit configurations and
message data.
In order to ensure function reliability, a self-test and a audio data verificati-
on is installed. The alarm takes place via an own output “Fault/Error”. The
device is maintenance-free because no battery or accumulator is installed.
Installation instructions
The appliance must be protected against:
- drip or splashwater
- direct sun irradiation
- high ambient temperature or direct influence of heat sources
- high air humidity
- heavy dust deposits
- strong vibrations
If the unit is brought directly from a cold to a warm place, dampness can
precipitate on the inner parts. The unit may only be put into operation after
it has warmed up to the ambient temperature (approx. after one hour).
Should an object or liquid get into the case, disconnect the unit from
the current sources immediately and have the device checked by a
DYNACORD service center, before further use.
Do not use any sprays to clean the unit, as these can damage it, perhaps
causing it to ignite suddenly.

Programming Examples for the DMM 4650
Page numbers within brackets (Sxxx) refer to the corresponding page of the DMM 4650's
user's manual.
The following examples are based on the assumption that the appliance's mode is set as follows:
Software revision 1.1 (page 22), the DMM 4650 is in the factory-preset mode (page 27 and page 36),
operation is performed in the user level 3 status (page 10).
Example 1
Intention:
Recording a message that later on is to be played back using a external key.
Summary
1. Recording a message (i. e. M03) in speech quality.
2. To include the reproduction of this message in an existing installation, an appropriate control
sequence has to be established that gets a priority between "fire alert" and "gong" (i. e. priority 90).
This sequence also activates an optical signal in form of a lit lamp for the period of the outgoing
message. To accomplish the task, this example uses the relay contact 2 of the port A (=A2).
3. An input, which at the moment is unused (i. e. B.4) had been connected to the "Start"-key (page
30). This input has to be programmed in the "Auslöser" (trigger) menu for that pressing the start
button activates the above mentioned sequence (S03).
Step By Step Programming
Enter the password for the user level 3 on the display,
using the four cursor keys (page 10) and confirm your
action with the "ok"-button.
If you have entered the correct password,
the display briefly shows this message and
then returns to the main menu.
After pressing this cursor key twice, the "Message"-
menu appears. Confirm your selection with the "ok"-
button.
Recording a message
On the display the message number 00 and the name
"Message" is shown. The numeric values mm=minutes
and ss=seconds equal the time of a message that
already exists in the register 00.
Pressing this cursor key three times displays the
required message register 03. The display shows the
name of the "empty" message 03.
Pressing the "record"-button displays a proposal
for the audio quality of the new recording (page
14). Using the soft key "ok" the proposition is
confirmed (speech quality).
On the display you are asked for the level setting (page
14). Since this is your first recording with the
microphone, the level has to be set a new. The
microphone has to be connected to the MIC-socket on
the front panel and pressing the soft key "yes", the
automatic adjustment process for the electronic control
is activated.

You have to perform a short test, speaking into the
microphone with a normal talking level and in an
appropriate distance. Whenever the display changes
from "<min" to "norm" the mic level is within the relevant
range.
Using the soft key "ok" the setting is being stored and
stays in memory (page 14).
In case the input level was too high and the indication
">max" has been displayed, you have to press the
"EXIT" button and follow the procedure once again from
the point where the record key was pressed. This time
the speaking distance to the microphone should be
increased; which results in a lower input level.
If the level was right ("norm" is shown on the display),
after pressing the "ok" key that the appliance is ready for
recording. The graphic bar in the lower line of the display
allows checking the input level. The Recorder is in the
pause-mode (ready to record).
Pressing the record button starts the recording.
The recording time gets displayed in m=minutes
and ss, s= seconds and the graphic bar offers
continuous verification of the actual input level.
Pressing the stop key terminates the recording
and the display shows the starting-menu
"message".
Pressing the button "start/stop" lets you control
your recording through the PHONES output.
If recording was not successful, you can give it
another try by pressing the "record" button. In this
case the display shows the message "delete?".
When you are sure that this is what you want, you
have to acknowledge the fact by pressing the
"yes" key.
The message 03 is being erased and a you can proceed with a new recording (RECORD key).
Recording quality and level setting only have to be re-adjusted if they were the cause for re-recording
the message.
Naming The Message, Title
To provide the new recording (message) with a new name, you have to follow these steps:
Press the soft key "edit".
In the display appears the sub menu "Message edit".
Using the soft key "ok", the system is ready to accept the
entry of a new name.

The name ("Message") with a maximum length of eight
characters can now be changed as desired. Using the
soft key "A-a" lets you choose between the upper and
the lower character set. By pressing the "spc" (space)
key you can enter spaces. The blinking cursor indicates
which character is going to be changed and using the
two "horizontal" cursor keys lets you select adjacent
characters.
The "vertical" cursor keys select the character that is
going to be entered at the cursor position. The example
shows the message 'Test 1.'.
After you have entered the desired title, pressing the
"EXIT" key once displays the question "save?". Press the
soft key "yes" to store the selected name for the
Message 03 into memory.
The display shows the starting menu for the message
programming.
Pressing the "EXIT" button once lets you return to the
main menu.
Programming A Control Sequence
Creating a procedure, the newly defined message has to be included into a sequence (page 23). In this
example the sequence-preset S 27 is chosen as the root-preset for further programming (page 39).
Press the "right" cursor key three times so that the
display reads as indicated. Using the soft key "ok" gets
you into the "Sequence" menu.
Pressing the soft key "ok" once again shows a menu that
lets you select a sequence-preset.
A blinking "0" (cursor) is displayed in the lower line.
Press the "up" cursor until the reading shows "S 27".
To acknowledge your selection press the "yes" key.
Since the procedure has to be changed in accordance to
the new requirements, you have to select its listing by
pressing the "ok" key.
The first step (step 1) of the S 27 listing is displayed.
Here, you have to change the relay output (indicator
lamp) from port C relay 1 to port A relays 2.
Press the indicated cursor key twice to have the "C"
blink.
Press the indicated cursor key twice to select port A.

Example 2
Intention:
You want to activate a factory preset alert using another key than pre-programmed.
Summary
Employing a previously unused input (e. g. B3) you want to trigger included DIN-alert of the DMM 4650.
The functioning of the input A4 which is already utilized for the DIN-alert has to be maintained. The
new, additional start-key has been already connected to the port B, input 3 (page 30). It has to be
programmed in the trigger menu to activate the sequence "DIN-Alarm" (=S22).
Step By Step Programming
Enter the password for the user level 3 on the display,
using the four cursor keys (page 10) and confirm your
action with the "ok"-button.
If you have entered the correct password,
the display briefly shows this message and
then returns to the main menu.
After pressing this cursor key twice, the "Trigger" menu
appears. Confirm your selection by pressing the "ok"-
button.
The display shows that input 1 of port A is disabled.
You can always change the character on which the
blinking cursor is positioned.
Pressing the indicated key positions the cursor on "Port
B". The bottom line in the display shows the momentary
setting of port B, input 1.
Pressing the indicated key positions the cursor on the
number of the input.
Pressing the indicated cursor key twice selects input 3.
The bottom line in the display shows the momentary
setting of port B, input 3 which triggers sequence 25.
To start the required alarm-sequence 22, you have to
press the indicated cursor key twice so that "5" appears
in the display.
Pressing the indicated cursor key three times displays
the required sequence number (S22).
Press the soft key "set" to store the setting.
From now on, the external button of the input B3 triggers the sequence 22.
Pressing the "EXIT" key twice ceases the programming.
The display is dimmed and you are able to test the
functioning of the sequence (example 2).

Example 3
Intention:
You want to trigger the pre-programmed 3-tone gong signal (factory-preset G21) by an external key.
The functioning of the 4-tone gong signal has to be maintained.
Summary
1. To include the reproduction of the 3-tone gong signal in the existing configuration, you have to
program a suitable control sequence (e. g. S05). The sequence is also about to trigger an external
control-lamp for the time, the gong signal gets reproduced. This example utilizes the identical relay
contact 4 of the port A (=A4) that is already in use for the 4-tone signal.
2. The unused input of the pre-gong signal (e.g. B4) has been connected to the start-key (page 30). It
has to be programmed in the trigger menu to activate the above sequence (S05).
Step By Step Programming
Enter the password for the user level 3 on the display,
using the four cursor keys (page 10) and confirm your
action with the "ok"-button.
If you have entered the correct password,
the display briefly shows this message and
then returns to the main menu.
Programming The Control Sequence
Creating a procedure, the 3-tone gong signal G21 has to be included into a sequence (page 23). The
sequence-preset S 25 is chosen as the root-preset for further programming (page 39).
After pressing the indicated cursor key five times, the
sequence menu appears on the display. Confirm your
selection by pressing the "ok"-button.
Pressing the soft key "ok" once again shows a menu that
lets you select a sequence-preset.
The blinking cursor is positioned at the "0" in the
display's bottom line.
Press the indicated cursor key repeatedly until "S 25" is
selected. Press the soft key "yes" to load the sequence
preset S 25 (root-sequence).
Since the procedure has to be changed in accordance to
the new requirements, you have to select its listing by
pressing the "ok" key.
The first step (step 1) of the S 25 listing is displayed,
which stays unchanged (relay contact A1 can be utilized
to turn the system's power on).
Pressing the indicated cursor key displays step 2 which
stays unchanged (release-input A1 of the electro
acoustic system ready?).
Pressing the indicated cursor key displays step 3 which
stays unchanged (relay contact B4 for music off).

stays unchanged (setting the volume of the gong
signals).
Pressing the indicated cursor key displays step 9. This
step normally would trigger the start of the gong signal
G20.
Press the indicated key four times to set the displayed
value under the blinking cursor mark to "0".
Press the indicated cursor key to select the gong signal
G21. This step activates the desired gong signal.
Press the indicated key twice to have the value "9" blink.
Pressing the indicated cursor key displays step 10 which

Pressing the soft key "yes" stores your new sequence-
listing as preset S05 into memory.
After showing a short message that
storing was successful, the display
returns to the start-screen of the
sequence.

Naming The Sequence, Title
In case you want to give the new sequence its own name, you have to follow this procedure:
Pressing the indicated cursor key enters the title-menu.
Pressing the soft key "ok" prepares the system for the
entry of a new name.
The name ("Vierklng") with a maximum length of eight
characters can now be changed as desired. Using the
soft key "A-a" lets you choose between the upper and
the lower character set. By pressing the "spc" (space)
key you can enter spaces. The blinking cursor indicates
which character is going to be changed and using the
two "horizontal" cursor keys lets you select adjacent
characters.
Using the two "vertical" cursor keys, the desired
characters can be selected. This example uses the
name "Dreiklng".
After you have entered the desired title, pressing the
"EXIT" key once displays the question "save?". Press the
soft key "yes" to save the selected name for the
sequence 05.
After showing a short message that the
storing was successful, the display
returns to the title-screen of the
sequence.
Pressing the "EXIT" key once lets you return to the main
menu.
This concludes the programming of your new procedure. The priority level of the sequence has not
been altered and is therefore equivalent to the setting of S 25 (4-tone gong signal).
Setting The Trigger
You want your new sequence to be triggered by pressing the desired button on port B input 4. Thus,
the programming is performed in the "Trigger" menu.
Pressing the indicated cursor key enters the trigger
menu. Press the "ok" button to acknowledge your
selection.
The display shows that the input 1 of the port A is
disabled.
Pressing the indicated cursor key selects the port B. In
the bottom line of the display, the setting for port B, input
1 is shown.
Pressing the indicated key sets the cursor to the number
mark of the input.
