User manual ELECTRO-VOICE 660A DATASHEET

[. . . ] 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 660A internally generated audio signals (e. g. gong signals with announcements), or given out as priority at the audio output (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. [. . . ] The functions of the factory presets S20-S37 are explained in tables on the pages 36 - 44. Erasing the factory presets is not possible. Probably the easiest way to create your own sequences is to modify already existing, possibly similar sequences (user or factory presets) and store them under different numbers together with their new titles and priorities. Operation menu sequence Confirming the menu selection "sequence" with the soft key "ok", using the cursor keys lets you select the following sub menus: Load Confirming "load" with the soft key "ok", "Sxx `title `and the soft keys "yes, no" appear on the display. Modifying the sequence number xx is possible by use of the cursor keys; the corresponding name is displayed. The selected sequence is loaded into memory with "y" offering the possibility for editing in other menus. Priority Confirming "Priority" with the soft key "ok", the display shows the priority number of the selected sequence. Using the cursor keys it can be altered in the range of 00 up to 99. 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. Stop trigger When confirming "stop trigger" with the soft key "ok", a menu is displayed which allows trigger settings for an input control line. Possible choices are described in the chapter"trigger". The stop trigger function is only available when the sequence commands "if stop" or "wt stop" are included. After pressing the "EXIT" key (previous menu level), the question "store yes, no?" appears on the display. The execution time lasts until End Delete Message (start of recording). -sets a timer to ttt, t seconds and starts measuring this time (sand glass). -sets a counter (event counter) to a starting value xxxx. With every "if count"-command the counter is decremented by 1 until 0 is reached. -resumes the sequence at step number xx. Audio Record Dly= Count= ttt, t s xxxx Jump if xx Delay -only executes the next step number if the delay time has elapsed (see command Dly). Otherwise the next step number is being skipped. The next step number is executed only if the counter has reached 0 (see command Count). If the counter value is greater than 0, the next step number is being skipped. Audio -executes the next step number only if the audio signal started at last is finished (see command start), otherwise the next step number is being skipped. In X, Y Z -executes the next step number only if the desired level Z (H or L) is applied at input Y (1 . . 4) of the I/O module X (A. . D). If this condition is not fulfilled, the next step number is being skipped. [. . . ] My installation should include the inputs B3 and B4 instead of the inputs C3 and C4 reserved in the preset. The indication lamps are not needed which makes retrofitting the port C not necessary. Performing the following changes is only possible for user 3!For when the indication signals are not needed, the steps of the sequences S 28 (play message M 02) and S 30 (record M 02) stay unaltered.
