VIDEO DISTRIBUTION AMPLIFIERS
ESE offers several DAs that operate with standard NTSC or PAL video signals. Described below
are the ES-207A (1x4), ES-208 (1x12) and ES-247E (Quad 1x6). The “Audio Counterparts” to
the ES-207A and the ES-247E are described on page 5.
The ES-247E is a quad 6 output Video Distribution Amplifier housed in a traditional rack mount
enclosure. Meanwhile, the ES-207A and ES-208 Video Distribution Amplifiers answer the “one
more unit” question with a versatile little package that can be stashed most anywhere, either
temporarily or permanently. Controls are accessible with a miniature screwdriver through
the front panel/top plate for Video Gain, HF Equalization and, in the case of the ES-208, DC
Level. A single pair of BNC connectors are wired for a loop through input.
Features:
• Ruggedized Enclosure • Video Gain & EQ Controls • Loop-thru Input
• Equalization For Up To 1000’ of RG-59 Cable
• Broadcast Quality Distribution
• DC Coupling Available
• Recessed Controls
These amplifiers can be used for distribution and for signal conditioning, with the EQ control equalizing up to
1000 feet of RG-59 coaxial cable. A very wide range of chroma level adjustment can be obtained with the
Gain control. The ES-208’s output video should be set for 0 VDC (using the DC control) on the blanking or
porch level, with video extending positive and sync negative.
