Technology and Digital Duplex® trademark
The technology and the Digital Duplex® trademark were created in the summer of 2000 especially for intercoms of a public address system "client cashier". The main accent was put on a qualitative sound and convenience of use (ergonomics).
The intercom of a public address system Digital Duplex DD - 205 T is intended for negotiations of cashiers or operators with the client through glass partitions.
Is the main component of a security system of cash desks of currency exchange. In this device 8 independent detectors of noise which adapt to a surrounding background are used. Digital Adaptive Detector (DAD) - the digital adaptive detector of activity within several seconds allows to lower an external background during long pauses between a talk. Use of such device is very effective, for example, in shopping centers, on railway and bus stations, at the airports where the level of background noise is rather high. The client can tell and listen to the operator at the same time. The operator was given an opportunity most to regulate the volume of sound and sensitivity of the microphone, and also, if necessary, to switch - off the microphone that to the client it was not heard that occurs indoors behind a soundproof partition.
Digital fine tunings, in particular, LED fine tuning of the status are provided in the device; the built - in non - volatile storage of current settings of sensitivity and loudness at power outage will allow to keep the last settings of the operator and at the return inclusion the device will automatically return to them. The soundtrack of pressing of the keys changing the tonality will prompt to the operator for what level of a sound and sensitivity of the microphone the intercom is ready at present. In the device, on an equal basis with the previous digital technologies, also digital detector of a voice of the operator and automatic adjustment of strengthening of a voice of the client is used. Existence of a linear exit (Line Out) allows to bring a sound to external loudspeakers, a loudspeaker, to make high - fidelity recording of negotiations, at connection of the intercom to the sound recording device. Integration with system of video surveillance and audiocontrol of Ewclid® is possible.
The bending microphone design developed in style of biodesign will help to arrange the intercom under necessary height, therefore, that the operator will be protected from an uncomfortable position at a conversation.
External anti - vandal calling panel
The external anti - vandal calling Topaz panel protects the device from mechanical influences, damages and differences of temperatures (an operating mode from - 40 to + 60). In this calling panel the auto - adjust of sensitivity of the microphone, loudspeaker loudness, a possibility of embedding of the hidden camera of video surveillance is used. Moisture - proofness of this model provides the double varnish coat applied on the printed circuit board of the panel. Thanks to steady against deleting of a tampopechata on the operator console and the epoxypolyester powder paint covering the client's panel, the intercom long keeps the original form and is reliably protected from chips.
The laid on calling Topaz panel can be mounted where installation of the classical "dimensional" panel is impossible, for example, on narrow jambs of apertures of doors, gates. Angular fastening by means of which the panel is installed at an angle 45 ° is included in the package. Installation of the panel is possible as indoors, and on the street.
The DD - 205 T intercom has a number of features:
Vandal proof tiny shock - resistant panel of the subscriber
Linear audio output / mikshirovanny/

Management and work
The carried scheme of processing of a sound and management which provides high quality of operation of the device is the basis for operation of the DD - 205T intercom. For processing of a sound 2 audioprocessors of Motorola are used (in the operator console and the subscriber's panel). For indication of operating modes of DD205T in the first crack of the loudspeaker over buttons the light - emitting diode is established. Indication of the modes is made as follows:
- The light - emitting diode does not burn - DD205T does not work
- The light - emitting diode blinks slowly - the microphone is switched - off
- The light - emitting diode blinks quickly - the sound is transmitted from the operator to the subscriber
- The light - emitting diode burns, without blinking - the sound is accepted by the operator from the subscriber
Main components of management of the panel of the operator:
- "MIC OFF" Shutdown of the microphone of the operator console.
- "POWER" Inclusion/power off.
- " - VOLUME" Reduction of loudness of the operator console.
- " + VOLUME" Increase in loudness of the operator console.
- " - SENSITIVITY" Reduction of sensitivity of the microphone of the operator.
- " + SENSITIVITY" Increase in sensitivity of the microphone of the operator.
Each pressing of the " + " or " - " button, is followed by a monophonic sound signal. At achievement of a limit of regulation in " + " or in " - " the tonality of a sound signal changes.
