DEM Series

The DPM 4000 represents the paging management/control unit of the ProAnnounce system incorporating all primary functions that are needed in advanced PA system installations. The DPM 4000 employs a digital audio matrix providing multiple audio I/O lines for up to 4 independent audio paths. Additional matrix junctions for the integrated gong and alarm signal generators, the vocal recording/playback unit, and the lock-on of the pilot tone and its evaluation are incorporated. All input signals and internally generated signals can be mixed inside the matrix and sent to the four output channels. Simple four-zone paging systems can be constructed using direct routing of output channels to dedicated zone amplifiers. Larger 5-100 zone systems can be constructed by using the DCS400 system controlled relay matrix either pre- or post- amplifier. The DPM 4000 provides priority control of pages and other functions. The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and pre-recorded messages. Signal generation is realized through DSPalgorithms, which are extremely flexible in use, so that they can be adjusted to match nearly any possible application. Factory presets include 6 different gong signals and 17 different alarm signals.

The DPA4410/11 amplifiers have been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines. The units are best suited for paging and pre-recorded message installations, alert systems, and for general music applications in industrial enterprises, offices, multifunction halls, sport arenas, schools, churches, hotels, hospitals, super markets, cruise ships, and similar venues. The DPA4410/11 amplifiers can either be operated on the AC mains or connected to an external 24 V battery power source. Switching to battery operation is accomplished via an internal relay. The DPA4411 provides the following remote monitoring functions when used within a ProAnnounce system: Setting input levels on channels 1-4 Reading level values of the audio level controls. Setting level offsets via virtual controllers. Mute function (via level controls). Remote control power operation ON/OFF. Battery operation remote control ON/OFF. Monitoring and fault message transmission of thermal overload warnings on the mains transformer or power output stages. Monitoring of the functioning of the power output stages 1 to 4 via pilot tone signal. Ground fault detection for loudspeaker lines.

The DPA4140 amplifier has been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines. The unit is best suited for paging and pre-recorded message installations, alert systems, and for general music applications in industrial enterprises, offices, multifunction halls, sport arenas, schools, churches, hotels, hospitals, super markets, cruise ships, and similar venues. The DPA4140 amplifier can either be operated on the AC mains or connected to an external 24 V battery power source. Switching to battery operation is accomplished via an internal relay. The DPA4140 provides the following remote monitoring functions when used with the remote modules in a ProAnnounce system: Setting input levels Reading level values of the audio level controls. Setting level offsets via virtual controllers. Mute function (via level control). Remote control power operation ON/OFF. Battery operation remote control ON/OFF. Monitoring and fault message transmission of thermal overload warnings on the mains transformer or power output stages. Monitoring of the functioning of the power outputstages via pilot tone signal. Ground fault detection for loudspeaker lines. One input module is required for proper operation of the DPA4140.  Two different versions are available.  The NRS90222 is the remote control version which allows for full monitoring and control through the ProAnnounce Designer software.  The other is the NRS90225 which provides only the XLR input connector and has no remote control functions available.  

The DTI2000 is a micro processor-controlled, completely configurable telephone interface for the Dynacord ProAnnounce system. The DTI2000 is used for connecting the DPM4000 System Manager to a telephone line or network to launch announcements from each telephone set over the loudspeaker network and to trigger signals, pre-recorded text messages and control functions (macros) of the DPM4000 System Manager using a telephone set. The DTI2000 is connected to an analog phone line and is controlled via tone-dial (multifrequency dialing). Using the supplied cable, the telephone interface has to be connected to a paging console input on the DPM 4000. The interface transmits serial control data as well as LF-audio signals. The DTI2000 appears at the DPM4000 as a special paging console allowing it to be programmed via the PC Designer Software in paging console dialog mode. The DTI2000 offers 100 call numbers (from 00 to 99). Any function can be assigned to any call number. Possible functions include zone or group selection, live-announcements with preprogrammable priority and pre-chime signal, playback of pre-recorded text messages and triggering of DPM4000 macros. The DTI2000 offers two different access levels with individual password protection. Depending on the actual application and desired operation, the DTI2000 allows initiating any possible function from a standard telephone set – from making a simple announcements up to triggering a sound reinforcement installation’s most complex sequential control procedures. Features Selection of up to 100 zones for announcements Programming of up to 20 call groups for group calls and collective calls Configuration of a call number chart of up to 100 numbers Selecting several zones or groups for announcements Initiating the playback of pre-recorded text messages Triggering of special functions (macros, erase zone / group selection) Assigning priorities for announcements and message playback Two level password protection Acknowledgement signals for O.K., faulty entry, busy, outgoing text message, etc. Automatic hang up: to specify the duration of announcements via internal Dip switches Trimmer on the front panel for setting the audio signal level Programming via ProAnnounce Designer Software equivalent to DPC4000 paging consoles Configuration possibility for world telephone standards (country-specific settings)
