Universal Compatibility
Works with Every TV in Cable or Antenna Mode
Your custom channels blend seamlessly with your existing cable (QAM) or antenna (ATSC) lineup. Every TV in the building tunes them in.
Each ULTRA+ channel creates a real digital TV channel that coexists with whatever your TVs already receive. Switch between QAM, ATSC, ISDB-Tb, DVB-T, DVB-C, and DMB-T directly from the front-panel color display — no computer needed.
Remote Control
Control Every Channel Via Web Browser
Manage your ULTRA+ channels remotely from any web browser — PC, tablet, or phone. Monitor status, change channels, adjust settings.
- Full IP web interface accessible over your local network
- Monitor and configure every channel from one screen
- Works from PC, Mac, tablet, or smartphone
- Real-time status monitoring and alerting
Audio
Broadcast-Grade Dolby Digital Audio
Studio-quality Dolby Digital audio encoding delivers immersive sound across every TV in your distribution system.
- Dolby Digital AC-3 Stereo LPCM encoding
- Passes through 5.1 surround from compatible sources
- Independently tested — best audio quality in its class
- Crystal-clear voice, music, and effects on every screen
Installation
Three Steps. Up to Eight Channels.
Connect HDMI. Set your channels. Scan your TVs. Every screen in the building shows your channels in Full HD.
Installation is fast: plug your HDMI sources into the ULTRA+ channels, choose channel numbers on the color display, then run a channel scan on your TVs. Every TV in the building now shows your content in crystal-clear 1080p Full HD with Dolby Digital audio. No computer required, no IT department needed.
The VeCOAX ULTRA+
High Density. Modular. Mission-Critical.
Four or eight independent channels in one chassis, each modular and hot-serviceable. The professional choice for broadcast facilities, large venues, and 24/7 operations. Made in USA with a 5-year warranty.
The VeCOAX ULTRA+ distributes 4 or 8 channels of any HDMI video source up to 1080p Full HD with Dolby audio to an unlimited number of TVs over your existing coaxial cables, with perfect digital quality at any distance. Built on the trusted MINIMOD platform: built-in color display, +45 dBmV RF output, secure IP web remote control, and compatibility with all worldwide TV standards. Completely modular and independent channel-by-channel — a replacement card installs in minutes without removing the system from operation.
Expandable Multi-Unit Systems
Add More Units. Recall the Preset.
Choose a 4-channel or 8-channel ULTRA+ per chassis, then expand larger systems by adding more units and recalling the next preset in one click.
A 4-channel ULTRA+ stays a 4-channel unit, and an 8-channel ULTRA+ stays an 8-channel unit. To grow beyond one chassis, add another ULTRA+ and recall the preset for Unit 1, Unit 2, Unit 3, Unit 4, and beyond. Each preset automatically assigns the required channel plan and related parameters so multiple units work together cleanly on the same coax system.
Compatibility

FAQ
VeCOAX ULTRA+ 4 / 8 Channel - Frequently Asked Questions
What is the VeCOAX ULTRA+?
The VeCOAX ULTRA+ is a modular multi-channel HDMI RF modulator that converts either 4 or 8 HDMI sources into independent Full HD digital TV channels over coax. It is built for hotels, venues, campuses, sports bars, hospitals, churches, and commercial headends that need centralized channel distribution.
What is the difference between ULTRA 4 and ULTRA 8?
ULTRA 4 creates four independent HD channels from four HDMI sources. ULTRA 8 creates eight independent HD channels from eight HDMI sources in the same high-density platform, giving larger systems twice the channel capacity.
Can I convert a 4-channel ULTRA+ into an 8-channel unit later?
No. A 4-channel ULTRA+ is built as a 4-channel chassis, and an 8-channel ULTRA+ is built as an 8-channel chassis. For larger systems, add additional ULTRA+ units and use the one-click preset recall to configure Unit 1, Unit 2, Unit 3, and beyond with the correct channel plan.
How many TVs can the ULTRA+ feed?
Unlimited. Each ULTRA+ channel can feed a few TVs or thousands of TVs over the existing coax network when RF levels, splitters, taps, and amplifiers are planned correctly.
Can ULTRA 4 and ULTRA 8 use existing coax cable?
Yes. Both ULTRA 4 and ULTRA 8 are designed to distribute channels over the coax already installed in the building, avoiding HDMI cable runs or receivers behind every TV.
Does the ULTRA+ output one combined coax signal?
Yes. The ULTRA+ is designed as a centralized multi-channel system where the channels are distributed through the coax network as normal TV channels. TVs scan and tune each channel just like cable or antenna programming.
Does the ULTRA+ work with QAM and ATSC TVs?
Yes. The ULTRA+ supports QAM and ATSC plus ISDB-Tb, DVB-T, DVB-C, and DMB-T. Use QAM for cable-mode TV lineups and ATSC for antenna-mode lineups.
Do I need a computer to set up the ULTRA+?
No. The ULTRA+ has a built-in color display for setup without a computer. It also supports IP web remote management for advanced control from a browser on the local network.
What HDMI sources work with ULTRA 4 and ULTRA 8?
Use cable boxes, satellite receivers, streaming players, cameras, computers, signage players, DVR/NVR systems, and video switchers. Each HDMI input becomes its own TV channel.
Can ULTRA 4 and ULTRA 8 work with 4K and 8K TVs?
Yes. The ULTRA+ creates broadcast-standard Full HD channels that tune correctly on HD, 4K, and 8K televisions. For true 4K RF channel output, add MINIMOD 4K for those specific 4K sources.
Is the ULTRA+ good for hotels and resorts?
Yes. Hotels use ULTRA 4 or ULTRA 8 for welcome channels, property information, event feeds, conference channels, signage, entertainment sources, and security views distributed to every guest-room TV.
Is the ULTRA+ good for sports bars and restaurants?
Yes. Sports bars can use ULTRA 4 or ULTRA 8 to distribute multiple games, menus, live camera feeds, event channels, or promotional content to every TV over coax.
Can churches and schools use the ULTRA+?
Yes. Churches and schools can distribute services, announcements, classroom feeds, sports events, signage, overflow rooms, and campus channels over their existing coax infrastructure.
Can hospitals and healthcare facilities use ULTRA 4 or ULTRA 8?
Yes. Healthcare facilities can distribute patient education, wayfinding, training, live video, public information, or internal channels to many TVs using the existing coax plant.
What happens if one ULTRA+ channel needs service?
The ULTRA+ is modular channel by channel. A channel card can be serviced or replaced without taking the entire system offline, which is important for 24/7 commercial and mission-critical systems.
What is the difference between ULTRA+ and RACK-4?
RACK-4 is a four channel rack system built from independent modulator channels. ULTRA+ is the higher-density centralized platform for 4 or 8 channels, expansion, and headend-style installations.
What is the difference between ULTRA+ and Mini Blade?
ULTRA+ is ideal for 4 or 8 centralized HD channels with modular serviceability. Mini Blade is the next step when you need 10 channels or more in a blade-style high-density rack system.
Can the ULTRA+ coexist with existing TV channels?
Yes. Assign each ULTRA+ channel to an open RF frequency so it does not overlap existing cable, antenna, or private modulator channels. TVs find the channels during a normal scan.
How do TVs find the ULTRA 4 or ULTRA 8 channels?
After assigning channel numbers and modulation settings, run an auto-scan on each TV in Cable/QAM or Antenna/ATSC mode. The TVs store the ULTRA+ channels like regular broadcast channels.
What RF output power does the ULTRA+ provide?
The ULTRA+ provides professional RF output around +45 dBmV, suitable for many commercial coax distribution systems. Large buildings should still follow proper RF level planning and amplification practices.
Is the ULTRA+ made for 24/7 commercial operation?
Yes. The ULTRA+ is designed for continuous commercial operation with modular cards, a 5-year manufacturer warranty, Made in USA support, and free lifetime technical support from Pro Video Instruments.
Why choose ULTRA 4 or ULTRA 8 for multi-channel TV distribution?
Choose ULTRA 4 when you need four centralized HDMI channels and ULTRA 8 when you need eight. Both versions provide high-density HDMI-to-coax distribution, centralized control, modular serviceability, and unlimited TV reach over existing coax.
