Extron MDA 5V (part number 60-446-01) — a composite video distribution amplifier from Extron's MDA Series, in a quarter-rack metal enclosure.

Worth being precise about the output count: this unit has six BNC outputs, five of them buffered for distribution and one a passive loop-through. That loop-through is the useful detail, because it lets the original signal continue to a downstream device or a local monitor without consuming one of the five active feeds. Bandwidth is 400 MHz at the -3 dB point with unity gain and 75 ohm impedance throughout, and the amplifier accepts anything from 0.4 to 2.0 Vp-p at the input while outputting at the same level. Sync handling covers NTSC 3.58 and 4.43, PAL and SECAM, so mixed-standard legacy plant is not a problem.

Key Capabilities

• One composite video input on a female BNC feeding six female BNC outputs.
• Five buffered distribution outputs plus one passive loop-through.
• 400 MHz bandwidth at -3 dB with unity gain across 75 ohm terminations.
• Output return loss below -30 dB at 5 MHz and DC offset within ±50 mV.
• Supports NTSC 3.58, NTSC 4.43, PAL and SECAM sync standards.
• Draws just 12 VDC at 0.1 A maximum from an external Everlast 6 W supply.

Where It Is Used

Legacy CCTV and surveillance headends, broadcast and production facilities still carrying composite feeds, classroom and auditorium video plant, industrial process monitoring, and clinical or laboratory installations where an analog camera signal must reach several recorders and monitors.
