The DC-300 counter-top ticket window intercom is designed for applications where a cutout in the barrier is impractical.
How It Works...
Two-way communication is accomplished through the use of speakers and microphones on each side of the partition. The inside Master unit is equipped with a 15" gooseneck microphone, power on/off switch, power-on LED, and external volume controls. The Remote unit is vandal resistant with all controls located within the metal housing.The DC-300 provides electronic two-way handsfree audio communications (duplex) between a partition. The DC-300 is equipped with a factory adjusted VOX switch to prevent ambient noise (below 85 decibels) from activating the unit. The DC-300 contains two voice channels, each incorporating a microphone amplifier, VOX switch, compressor, and a power amplifier. The sound amplifier does not exceed a 0.2% total harmonic distortion rating.
How To Install...
The DC-300 comes ready to operate. The prism units are quickly and easily mounted on the counter-top on opposite sides of the barrier. They can be positioned back-to-back (as shown) or randomly. The unit with the gooseneck microphone and controls goes inside the booth; the unit without controls is mounted outside the booth. There are two ways to install the DC-300: either run the cable between the units through a small hole in the barrier ('A' type mounting), or under the counter-top ('B' type mounting) (as shown on the left).
