Multi-Channel & Modular HDMI Modulators

Multi-channel HDMI modulators put several HDMI sources on their own digital TV channels at the same time, distributed over a single coax network to unlimited TVs. They are the backbone of hotel TV systems, sports bars, stadiums, campuses, hospitals and corporate headends, where guests and viewers expect to flip between many in-house channels exactly like regular TV.

This collection covers every VeCOAX modulator that delivers two or more channels. The modular MINI BLADE scales from 1 to 10 channels — order exactly the count you need today and add independent modules later. The RACK-2 (2 channels) and RACK-4 (4 channels) are rack-ready systems that drop straight into a 19-inch equipment rack. The flagship VeCOAX ULTRA+ delivers 4 or 8 hot-serviceable channels with modular cards you can replace on site with zero downtime to the other channels.

Every channel is fully independent, broadcast-grade Full HD 1080p with Dolby Digital audio, and individually tunable on the color display — no computer required. The +45 dBmV output and MER above 45 dB keep every channel crystal-clear across thousands of feet of existing RG6/RG59 coax. All units support QAM, ATSC, DVB-T/C and ISDB-T worldwide standards.

Combine outputs with a coax combiner to merge all channels onto one cable, and mount compact units with our 1RU rack panel. Everything is backed by a 5-year warranty, free unlimited tech support, same-day shipping, and is designed and made in the USA.

Buyer's guide

Choosing a multi-channel headend

Modular or fixed-channel?

If your channel count may grow, choose modular: the MINI BLADE lets you buy 1–10 channels and add modules later, and the ULTRA+ starts at 4 channels and expands to 8 on site. If your count is fixed and you want a clean rack install, the RACK-2 and RACK-4 are turnkey 2- and 4-channel systems.

What does hot-serviceable mean?

On the ULTRA+, each channel is an independent card. If you ever need to service one channel, the others keep broadcasting — critical for hotels and venues that cannot go dark.

How do I combine all the channels onto one coax?

Feed each modulator output into a coax combiner. The combiner merges every channel onto the single coax network already in your building, and every TV scans them as normal channels. There is no limit to how many TVs can watch.

Will all channels stay broadcast-clean?

Yes. Each channel runs at +45 dBmV with MER above 45 dB and MPEG-2 broadcast encoding, so picture and Dolby Digital audio stay locked across long cable runs.
