A professional modulator has to lock cleanly on both QAM cable tuners and ATSC antenna tuners. The MINIMOD 2+ earned NAB Product of the Year, CE Pro Best, and CEDIA Best of Show because it delivers broadcast-grade output on every standard: +45 dBmV and MER above 45 dB, so TVs lock instantly whether you're feeding a QAM lineup or an ATSC lineup.
Recognition
The Professional QAM / ATSC Modulator Trusted Since 2017
When a job calls for QAM on one site and ATSC on the next, professionals carry one VeCOAX MINIMOD 2+ instead of two modulators — award-winning, US-built, proven on 50,000+ installations.
How a QAM / ATSC Modulator Works
HDMI In → A QAM or ATSC Channel on Every TV
A professional QAM/ATSC modulator encodes your HDMI source and modulates it as either a QAM (cable) or ATSC (antenna) channel on your coax. Every TV finds it on a normal scan in the matching mode — no new HDMI runs, no network.
- Feed any HDMI source into the modulator — cable box, Apple TV, camera, signage player, laptop Built for qam atsc hdmi modulator installations.
- Choose QAM or ATSC on the LCD — then pick a channel number
- Connect the coax output into your existing cabling or a combiner Built for qam atsc hdmi modulator installations.
- Auto-scan each TV in the matching mode — the channel appears in full 1080p
- No HDMI cable length limits, no splitters behind every screen, no streaming boxes Built for qam atsc hdmi modulator installations.
- Mix QAM and ATSC channels on the same coax with multiple modulators
Setup
Switch Between QAM and ATSC in Seconds. No Computer Required.
Most professional modulators force you to plug into a laptop to change standards. The MINIMOD 2+ puts QAM, ATSC, channel, and output level on a high-resolution color LCD right on the box.
- Built-in color LCD shows standard, channel, frequency, and signal status at a glance
- Switch between QAM and ATSC right on the front panel — no firmware swap
- No PC, no software, no app — the modulator is fully self-contained
- Power on → choose QAM/ATSC → pick a channel → connect coax → scan TVs → done
QAM, ATSC & Beyond
One Professional Modulator for QAM, ATSC and Every Standard
QAM for cable tuners, ATSC for antenna tuners, plus DVB-T, DVB-C, and ISDB-T for international systems — all selectable on the LCD. One box covers every job.
QAM and ATSC are the two North American digital standards — QAM for in-building cable systems, ATSC for over-the-air antenna systems. Rather than stock both, professionals carry the MINIMOD 2+ and select whichever the site needs on the LCD.
Travelling or working internationally? The same modulator switches to DVB-T, DVB-C, or ISDB-T — truly one box for any TV plant on earth, in HD, 4K, or 8K.
Remote Control
Manage QAM & ATSC Channels From Any Browser
The front-panel LCD handles setup, but when modulators live in a rack you can also monitor and retune them — and switch standards — remotely through the secure web interface.
- Optional web interface for remote standard, channel, and level changes over the LAN
- Manage a whole rack of QAM/ATSC modulators from one browser tab
- Works from PC, Mac, tablet, or phone — no app to install Built for qam atsc hdmi modulator installations.
- Live status and alerts so you know every channel is on-air Built for qam atsc hdmi modulator installations.
Audio
Broadcast-Grade Audio on Every Standard
Whether you output QAM or ATSC, the MINIMOD 2+ encodes broadcast-grade Dolby Digital so audio arrives locked to picture on every television.
- Dolby Digital / LPCM audio carried in both QAM and ATSC channels
- Tight lip-sync from input to every TV — no drift over long coax runs Built for qam atsc hdmi modulator installations.
- Passes 5.1 surround from compatible HDMI sources Built for qam atsc hdmi modulator installations.
- Clean voice, music, and effects on every screen Built for qam atsc hdmi modulator installations.
Installation
Three Connections. Done.
HDMI in. Coax out. Channel scan. Your source becomes a QAM or ATSC channel on every screen — in Full HD with synced audio.
A professional QAM/ATSC install with the MINIMOD 2+ takes minutes, not days. Connect the HDMI source, run the F-type coax output into your existing cabling, choose QAM or ATSC and a channel on the LCD, and auto-scan the TVs. No network to configure and no decoders behind screens — the coax does all the work.
The MINIMOD 2+
A Professional QAM / ATSC Modulator With Headend Quality
Palm-sized aluminum build, spurious-free QAM and ATSC modulation, and a front-panel LCD — the professional way to deliver either standard. Made in USA with a 5-year warranty.
The VeCOAX MINIMOD 2+ outputs QAM and ATSC the way broadcasters do: full 1080p at 60fps MPEG-2 video, Dolby Digital audio, +45 dBmV output to drive long coax and splitters, a built-in color LCD to switch standards without a computer, and support for every worldwide TV standard. One small box covers QAM cable jobs and ATSC antenna jobs alike.

When you need many channels at once across both standards, the MiniBlade rack kit delivers maximum density with independent power per unit. There is no shared point of failure: every QAM and ATSC channel runs on its own, which is exactly what 24/7 professional systems demand.
Compatibility
Every TV Tunes Your QAM or ATSC Channel — HD, 4K, and 8K
QAM and ATSC are standard digital signals, so any TV with a digital tuner decodes them perfectly — from a decade-old HD set to the newest 8K display.
Because the MINIMOD 2+ outputs standards-compliant QAM and ATSC, virtually every modern television decodes its channels with the built-in tuner — QAM in Cable mode, ATSC in Antenna mode. Color space, frame rate, and audio sync are handled inside the modulator, so the picture looks right on every brand and resolution.
