Overview
The 570D-H (DanteĀ®) series digital communication stations are fully programmable touch screen user interface devices for initiating audio / visual announcements, messages, and pages with the GLOBALCOMĀ® Series Announcement Control Systems. Each model utilizes an electret condenser cartridge that is positioned in the housing such that its frequency response is enhanced. The microphone element location provides the mechanism for good acoustical coupling to provide a full-bodied, highly intelligible voice signal.
The 570 has an auxiliary line level audio input which may be used as a (local) background music source. The station also has a line level audio output which may be used as a zone out.
The 570 is a network appliance in which each station may obtain its IP address automatically or be assigned a unique IP address which simplifies installation and configuration.
The handheld microphone assembly contains an omnidirectional electret condenser microphone cartridge integrated with a microphone preamplifier and an audio line driver. The microphone element and preamplifier are mounted in a teardrop shaped molded black textured Cyclolacā¢ housing. The use of an omnidirectional element eliminates the proximity effect which creates a boomy sound when a user speaks close to a microphone.
The electret condenser microphone cartridge consists of a high voltage internal membrane, metal electrode and a Field Effect Transistor (FET). The requirement for a high voltage bias is not necessary as with ordinary condenser microphone elements. The cartridge features include a highly efficient electrical specification, pressure type operating principle, low impedance (2.2 kĪ©), and high reliability under adverse shock, vibration and other environmental conditions.
It utilizes a magnet for attachment to the microphone station base assembly and is supplied with a circular coiled cable which is built into the housing assembly. A strain relief is built into the housing end of the cable and locks into the housing. The terminations at each end are molded, 6 wire, RJ25 connectors which provide extra strength and resistance to failure by pull-out.
