EL1800 Plus - 1x6 video distribution amplifier
clamped, differential and 3 bands equalized

All video distribution amplifiers have the same basic function, generating from a video input several outputs.
Features such as differential input, equalizing response or clamping are not necessarily present in each model and performance differs according to specifications and features.
Now you can have all the above at an affordable cost in Elman’s EL 1800 plus, a high-performance differential input, 6 outputs, 3 band video equalizing and clamping amplifier designed to compensate for attenuation, phase errors and noise associated with cable runs.
The EL 1800 plus is a stand alone that can be accommodated in the ELMAN’s 1 RU RMA multifuction-system subrack which can be inserted up to three standalone modules simultaneously.
The EL 1800 plus can be independently utilized also being the apparatus provided with its own power supply and with all the necessary connectors on a rear panel.
