1x6 PAL Distributor / Equalizator with Clamper Supply

broadcast DE107 broadcast DE107 broadcast DE107


DE107 is a high performance composite video signal distributor with 1 loop input and 6 outputs adapted to 75Ω.

The DE107 internal power supply, which generates the tensions to operate the unit, is of the soft start kind, so absorbing peaks are avoided when several units are turned on simultaneously.

The DE107 mounts in its inside an original "watching net" which controls all DC levels in the circuitry. Any time an anomalous level is detected it is signalled as a failure by the red led on the plug front panel.
