CANFORD VIDEO DISTRIBUTION AMPLIFIER

Housed in the standard Canford extruded box with protective ABS bezels, the unit accepts a standard 1Vp/p video signal on a BNC connector (75 ohm termination). A parallel unbuffered input connector is provided, which can be used for looping through to another piece of unterminated equipment.

The amplifier provides 5 outputs on front-panel BNC connectors. A single 16 position switch allows control of the gain and equalisation applied to the signal: each step provides correction for approx. 25m of standard VCS (BBC PSF1/3) type cable, with a maximum correction capacity of approx 375m. This method of equalisation control enables approximate setting without reference to a waveform monitor; simply measure the length of unequalised cable, divide by 25 and dial up the result on the switch. A setting of zero gives unity gain and flat response.

An on/off switch is provided on the front panel, and a green Power LED flashes to indicate low supply voltage. Power is derived from an internal Alkaline PP3-size battery, or an external power supply can be plugged into the rear connector.
