User manual ELECTRO-VOICE DMM 4650

[. . . ] OWNER'S MANUAL DMM 4650 Description The DMM 4650 is a signal processor which allows for an universal generation and control of audio 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). [. . . ] Acknowledging this question lets you save your new settings in a user preset. Step list When confirming "step list" with the soft key "ok", a menu is displayed which allows the indication of all individual steps of a sequence. In caes the listing of a certain sequence is supposed to be edited, the sequence has to be loaded into memory, first (menu "load"). The cursor keys are used to modify the step number and its corresponding function (see list of available step functions). The soft keys "d = delete" and "i = insert" simplify the editing of step listings by deleting or inserting complete rows of steps at the currently displayed step number. In order to test the functionality of a sequence before the actual storing process is performed, it is possible to launch the sequence including all audio signal and control line results by pressing the PLAY/STOP and RECORD-(stop trigger) keys. Pressing the EXIT key immediately cancels the test function. After pressing the "EXIT" key (previous menu level), the question "store yes, no?" appears on the display. Acknowledging this question lets you save your new settings in a user preset. 23 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. After pressing the "EXIT" key (previous menu level), the question "store yes, no?" appears on the display. Acknowledging this question lets you save your new settings in a user preset. Save Confirming "save" with the soft key "ok" displays the number of the currently selected sequence. The cursor keys are used to enter the desired sequence number. Saving has to be confirmed using the soft key "y= yes". Choosing "save" stores all modifications made in the above mentioned menu items into the selected user preset. Thus, individual saving the parameters in not necessary, since they remain in memory until another sequence is loaded. If a factory preset sequence (S20, S21, . . . ) is chosen for saving, only the `stop trigger" is stored. Sequence example Via "sequence" > "load" > S28 > "step list" the step function listing of sequence S28 with the name `Message 2' is being selected, which shall serve as a simple example. The purpose of this sequence is the indication of a lamp signal and the playback of a previously recorded message to its end.

The message priority is identical with the sequence priority. [. . . ] Only the button C4's stop operation is altered into B4 in the sequence S 30. The new setting is re-stored under S 30. The trigger B3 is selected in the "trigger" menu and the start sequence is changed from S 25 into S 28. Confirming the soft key "set" activates this new setting (play M 02). [. . . ]
