XLR mic/line inputs, eight GPI control inputs, two XLR outputs capable of either independent or stereo operation, and two VCA level inputs. In addition, two of the XLR mic/line inputs can be configured for paging with adjustable ducking. The DRM 4000 can be programmed to change its configuration through presets assigned to the GPI inputs, PC control
Volume And Tone Controls / Delays
The ProAnnounce system provides individual volume controls for each input, output, and paging station. Even the internal audio sources, like gong/alarm tone generators, voice message playback, and pilot tone generator employ individual level controls, each. Additionally, it is possible to set an attenuation that unanimously affects the inputs. This value determines the degree, by which the input signal is attenuated during the reproduction of messages or other signals with a higher priority setting. This allows to smoothly
Besides, each of the four inputs embodies three fully parametric digital filters allowing for optimal tone control. The filters provide different filter types like
Setting volume levels and filter parameters is accomplished via PC during the configuration procedure. Further, it is possible to alter any volume setting during the later operation of the system via
All four outputs employ digital delays allowing signal delays of up to 330 ms per channel. Natural delays, resulting from loudspeaker positioning, which causes time differences in the arrival of sounds or environmental circumstances related to architectural characteristics of the location, can be equalized without additional effort.
Signal Generators / Voice Message Memory
The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and text signals. Signal generation is realized through
In addition, a voice message recording/playback module providing
Control Inputs And Outputs
By using the control inputs, it is possible to link the ProAnnounce system to fire alert systems, burglary alert systems, or to a central operating desk. It is also possible to connect external switches, breakers, rotary controls or rotary encoders, respectively to query control outputs of external units (power supplies, power amplifiers).
