Communication Station (PZA)
Digital communication station with touchscreen and CobraNet® messaging channels with handheld microphone
The IED550CS-H/G digital communications station is a fully programmable touchscreen user interface device for initiating audio-visual announcements with GLOBALCOM announcement control systems. Each model uses an electret condenser cartridge that is placed in the housing in such a way as to improve its frequency response. The location of the microphone element provides the mechanism for good acoustic coupling to provide a full-bodied, highly intelligible voice signal. The IED550CS-H includes a handheld microphone.
The IED550CS has an auxiliary line-level audio input that can be used as a background (local) music source. The station also has a line-level audio output that can be used as a zone output.
The IED550CS is a network device where each station can obtain its IP address automatically or can be assigned a unique IP address, simplifying installation and configuration.
The gooseneck microphone contains an omnidirectional electret condenser microphone cartridge integrated with a microphone preamplifier and audio line controller. The microphone element is mounted on the metal part of the gooseneck windscreen. The preamplifier and line driver are on a PC board mounted inside the gooseneck base on an XLR connector. The microphone assembly is a 12” gooseneck with a hard metal windscreen on top and a 5-pin XLR connector at the base for mounting.
Handheld microphones
The handheld microphone assembly contains an omnidirectional electret condenser microphone cartridge integrated with a microphone preamplifier and audio line controller. The microphone element and preamplifier are mounted in a black textured teardrop-shaped molded Cyclolac™ housing. The use of an omnidirectional element eliminates the proximity effect that creates a boomy sound when a user speaks close to a microphone.
It uses a magnet to attach it to the microphone station base assembly and comes with a circular coiled cable integrated into the housing assembly. A strain relief is incorporated into the end of the cable housing and locks into the housing. Terminations at each end are molded 6-wire RJ25 connectors that provide additional resistance to pull-out failure.
Cartridge features include highly efficient electrical specification, pressure-type operating principle, low impedance (2.2 kΩ) and high reliability under adverse shock, vibration and other environmental conditions.
