BLONDER TONGUE VACD-12 VIDEO ALL CALL DISTRIBUTOR with 12 AB-800 PIN DIODE SWITCHES It is used but appears to be in good working condition. It powers up and was taken from a working environment. Video All-Call System - Provides Override of All Channels on the System Compatible with CATV or Off-Air Systems Distributes Signals Throughput Installation Including Locally Modern school systems often incorporate audio (paging or intercom throughout the school) with traditional video distribution (delivering a number of channels to each classroom). Video distribution allows the school to interface with local cable television and deliver topical programs to each classroom, originate local programming (either live or playback via a VCR) and provide to every room in the school. Additionally, emergency or general announcement information can be quickly delivered with both audio and video information to each television in the school. Blonder Tongue manufactures a complete line of products for implementing a Video All-Call System. These systems provide an integrated solution of allowing one channel to override all other channels on all televisions in a school system. In order to integrate all of these components into a complete all-call system, Blonder Tongue offers the VACD- 12 Distribution Amplifier and the AB-800 Pin Diode Switch. These two products are used to distribute the alternate audio/video program to each modulator and processor in the system. When invoked, the substitute IF program will override the normal IF programs available at each modulator and processor. Every channel in the system will be overridden with the new program. IF Input Frequency Range: 41 to 47 MHz Output Frequency Range: 41 to 47 MHz AB-800 Control Voltages: 15 VDC Temperature Range: 0 to +50 C IF OUTs (12): "F" Type, Female IF Test Port: "F" type, female We are a recycler of surplus electronics and other cool stuff.
