Title: 4 Channel Video Distribution Amplifier
Category: A/V Baseband
Industry: CCTV/Security, TV/Radio Broadcast, CATV Cable Industry
The VDA414 Video Distribution Amplifier is used to amplify and distribute any B/W or color NTSC, PAL, or CCTV video signal. The unique design allows the user to change the inputs and outputs to make any of the following amplifier configurations. Selectable User Configurations: Inputs Outputs Video Channels 1 In 2 Out 4 Separate Channels 1 In 4 Out 2 Separate Channels 1 In 6 Out 1 Channel with an extra 1 In / 2 Out 1 In 8 Out 1 Video Channel 2 In 4 Out 2 Separate Channels The video level for each input channel is adjustable to allow the user to set the proper level for the down stream equipment. This adjustment is useful when feeding signals to a DVR (Digital Video Recorder) or other digital devices. DVR’s and digital devices are very sensitive to over and under video level, so the ability to adjust the level prior to the device is sometimes necessary. The VDA414 is a PC card that fits into the RMS400 Power supply and Mainframe. The RMS400 is a 19.00″ X 5.25″ industry standard rack mount. The Mainframe and power supply will hold up to Nine VDA414 4 channel distribution amplifiers. This allows 36 channels of video distribution in 3 standard RU or “rack units” of space. The power supply to power the cards is supplied with the RMS400. VDA414 FEATURE SPECIFICATIONS: INPUT Level 0 to 4.0 Volts (1 Volt Typ.)

Mounting Slide-In PC Card (RMS400) VDA414C CLIPPER CLAMPER VIDEO DISTRIBUTION AMPLIFIER This video DA is also available in a Clipper Clamper version. The VDA414C has the ability to clamp out low frequency interference and distortion by back-porch clamping the video signal. It also has a front panel adjustment for clipping level that allows the operator to set a hard clip level on the video to prevent over modulation of the down stream equipment. A front panel LED indicates the point of video clip. The ordering nomenclature for the Clipper Clamper version of this product is VDA414C.
