Description
TheDMM4650isasignaiprocessorwhichallowsforanuniversaigenerationandcontrolofaudio-signals. Its main
purpose is the installation in electro-acoustic rack systems, but stand-alone applications are possible as
well. The audio signals can consist of alarm, gong, voice messages but also of random combinations of
these sources. The programs were created by Dynacord (preset). Anyway, it is possible for the user
(consulting company, etc.) to modify those programs and store them as user-programs. The audio input
can be mixed with the DMM 4650 internally generated audio signals (e.g. gong signals with announcements),
or given out as priority at the audiooutput (programmable).
The audio quality of the messages can be selected, depending on memory extension and different user
requirements. With maximum memory extension, a total recording time of 16 minutes is possible. Password
protection for various operation levels is provided. For "EASY-USER", the provided operation features are
similar to those known from cassette recorders or CD players. The control of the programs is performed
via floating inputs and floating outputs provide status messages. The priorities and functions of these
lines can be programmed individually (Setup). A computer interface facilitates saving and loading of the
unit's configuration and its message data.
In order to ensure functional reliability, self-surveiliance and audio data verification are employed. The
alarm is ignited via internal fault-output while all warnings are logged. The DMM 4650 is maintenance-
free since no serviceable parts, batteries or accumulators are to be found inside the appliance.

  • Page 8: Use Of The Dmm 4650

    Use of the DMM 4650 The DMM 4650 can be used in both, incorporated in a rack shelf system or as stand-alone unit. The installer should automate the daily sequences by external control keys, sensors, contacts and the corresponding unit settings. This applies for gongs, alarms, messages and their combinations, as well as for recordings of variable announcements.

  • Page 9: Sequence Functions

    A switch is connected to one of the DMM 4650’s control inputs (Al - D4). The desired input is selected in the trigger menu. Logic level (high, low), delay, and function (dyn, stc, latch) can be set. The desired sequence (Sxx) gets chosen here as well.

  • Page 10: Operation Of The Dmm 4650

    Password entry, operation end Pressing any key on the DMM 4650’s front panel, ”Password ?” appears on the display. Using the cursor keys you have to enter a 4-digit number and confirm it with the menu key ok. After entering the correct 4-digit password, the display shows the number of your user level.

  • Page 12: Message

    Up to 1 00 distinct messages (MOO to M99) including title, name, and priority can be saved. The DMM 4650 is shipped without any prerecorded messages, since - depending on individual user requirements and custom applications - variations would be numerous. Some factory preset sequences use MOO, M01, and M02 (see list of preset sequences).

  • Page 13: Soft Key "Edt

    Soft key ”edt” Using the ”edt”key in playback mode provides the opportunity to edit and manage your message structure. The keys are used to select the following menu items. Title Confirming ”Title” with the soft key ”ok” the selected message’s current name appears on the display. Using the cursor keys lets you enter a name which can consist of up to 8 characters.

  • Page 14: Level Adjustment, Record Level

    Recording level An integrated, electronic control automatically adjusts the input sensitivity of the DMM 4650’s (Mic, Line, Rec. lnp) inputs. This level setting remains unchanged, until the question ”Select new recording level?” is answered by using the soft key ’)/=yes”before starting a new recording. By using a short test signal marks the new setting of the control which is automatically stored.

  • Page 15: Gong

    GONG General Gong Presets are audio signals that can be started within a sequence. Order and parameters of a gong sequence can be edited. For test purposes the sound can be started in the ”gong > editor” menu by use of the PLAY/STOP keys. it is audible via the Pre-Listen outputs.

  • Page 17: Alarm

    ALARM General: Alarms are audio signals that can be started within a sequence. The alarms are square wave forms providing the possibility for various parameters to be adjusted. For test purposes, it is possible to start the alarms signals in the ”alarm editor”menu using the PLAY/STOP key.

    (Mic, line, Rec-inp) directly to the sum output. Especially in stand-alone applications this option is particularly useful, since it will possibly save one microphone amplifier. Starting the function is either performed in the DMM 4650’s operation menu or remotely controlled via a control line. For external operation a sequence is provided as factory preset S32 (page 42) which is easily adapted according to individual requirements.

  • Page 21: Trigger

    General The menu trigger allows to assign the connection of a control input to a function of the DMM 4650 (sequence start) while various control inputs can initiate a single sequence. The separate logic control settings for each input provide the possibility to optimally match the requirements of an installation.

  • Page 22: Trigger Detection

    Triaaer recognition The level of the control inputs are periodically monitored by the processor. The sampling time (Ts = sample rate) is typically Ts typ = 30 msec. The maximum monitor interval can be set to Ts max = 1 00 msec. Thus, shorter impulses, spikes or quick AC voltages are recognized inaccurate or with a delay (undersampling).

  • Page 23: Sequence

    SEQUENCES General: Sequences are a series of single steps, determining the functions of the DMM 4650 step by step. Thus, providing the possibility to define signal sequences, volume levels, trigger outputs, time sequences, loops, etc. Triggering an input (”trigger) normally starts a sequence. However, for test purposes it is possible to start a sequence via menu com- mand.

  • Page 24: Title

    Title Confirming ”title” with the soft key ”ok”, the name of the currently loaded sequence appears on the display. Using the cursor keys offers the possibility to enter a name of maximally 8 characters. The soft keys ”A-a” and ”spc” shift between the upper and the lower character case or enter a blank character, respectively.

  • Page 29: Self-Test

    The scrolling text records the first and last occurence of the error (see ”setting clock”). The EXIT key terminates this menu (return to the prior menu level). Note: Error no. 1 only counts the switching ”on” and ”off’ of the DMM 4650, but does not lead to an external error display (Power On Reset).

    Control levels and currents: Power source -Batt. / +Batt. corresponds to a supply voltage of (20V - 31 V) of the DMM 4650. For current limita- tion (fuse), a PTC resistor (positive temperature coefficient resistor) is provided at the +Batt connection of each port.

  • Page 32: Audio Inputs And Outputs

    Audio inputs and outputs The XLR inputs and outputs are electronically balanced and wired according to the IEC 268 standards. If unbalanced XLR connection is desired, PIN1 and PIN3 have to be bridged using ajumper. Specifications are to be found in the appendix on page 53. If balanced, floating connection is necessary, the extension kit NR 9021 1 has to be installed for the INPUT and NR 9021 0 for the OUTPUT.

  • Page 33: Remote, Rs 232 Connection, Data Backup

    Backup, Restore commands, Priority The ”backup” command can be given both, from the DMM 4650 menu ”System setup > backup”, as well as via the REMOTE interface. After starting the backup procedure, the desired data is transmitted in the previously determined format via the REMOTE interface.

  • Page 34: List Of Remote Commands

    ”System setup > Restore > ok” The DMM 4650 confirms the successful restoration by displaying the message ”Preset xx restored”.

  • Page 35: Terminal Programs

    If necessary, the later allows to change the data (only inserting or deleting whole text lines, see backup, Restore commands above). The text editor should not decode and re-code any characters. If the backup data is supposed to be loaded back into the DMM 4650, the function Restore has to be activated first (see backup, Restore commands).

  • Page 36: Factory Presets

    The user can edit these defaults according to individual requirements. The data of the menus ”outputs” ”standby” and ”sum level” determines the status of the DMM 4650 in stand-by mode (no sequence running). A running sequence could lead to a modification of the outputs. Upon completion of the sequence, the outputs are switched back to their previous status (stand-by mode).
