The IEC-750 video distribution amplifier reflects the latest in the state of the art in engineering techniques. The IEC-750 is the most versatile video amplifier yet conceived, offering outstanding performance. The input is high impedance loop through in the 1x8 mode of operation. In the dual 1x4 mode, the input is terminated internally. The dual mode of operation provides four outputs of each of the two inputs. The versatility of the IEC-750 is illustrated by its choice of operation. Several unique features are standard with this stand-alone video DA.
A switch on the rear panel allows the unit to operate as a dual DA with two terminated inputs with four outputs each. Two gain controls on the front panel adjust the video level to +/-3dB for each set of four outputs. A switch on the rear panel allows for differential or single-ended inputs.
The IEC-750 has a video bandwidth of 20 MHZ, making it a very useful device for any application. A fuse on the front panel provides easy replacement. The IEC-750 is a self contained video DA with an on board power supply that draws only 4 watts. Three units can be mounted in a 1 RU frame.
