Frequently Asked Questions
What is an HDBaseT extender, and when would you use one?
An HDBaseT extender is a device that sends HDMI video, embedded audio, and often control signals over a single Category cable instead of a short HDMI cable. It is commonly used when the source equipment and display are too far apart for reliable direct HDMI runs, such as in classrooms, conference rooms, training spaces, and residential media installations.
The Atlona AT-AVA-EX70C-KIT is a point-to-point HDBaseT extender kit designed for exactly that job. It extends 4K/UHD 60 Hz 4:2:0 signals up to 130 feet and 1080p 60 Hz signals up to 230 feet over Cat6 or Cat6A. It also passes bidirectional RS-232 and IR, which helps when a display or source needs remote control without separate control wiring.
This type of extender is a strong fit for organizations that want a clean, reliable AV path from a room PC, instructor station, or media source to a projector or flat panel at the front of the room. It is less suitable if you need network switching, AV over IP, or matrix-style routing between many rooms.
What is the difference between a basic HDMI extender and an HDBaseT extender?
The main difference is capability and reliability over distance. A basic HDMI extender may only send video and audio and can vary widely in performance, especially at higher resolutions. An HDBaseT extender is built for professional AV use and typically carries video, audio, control, and sometimes power over one Category cable.
The Atlona AT-AVA-EX70C-KIT is an example of a professional HDBaseT extender kit. In addition to extending HDMI content, it supports bidirectional RS-232 and IR pass-through and uses remote power, meaning the transmitter powers the receiver over the same Cat6 or Cat6A cable. It also includes EDID filtering, clock stretching, and an integrated HDBaseT link test to help maintain stable operation and simplify troubleshooting.
For B2B, university, and government environments, HDBaseT is usually the better choice when reliability, clean installation, and control integration matter. A simpler HDMI extender may be fine for short, noncritical runs, but it often lacks the diagnostics and control features needed in managed AV systems.
Do you lose video quality with an HDMI or HDBaseT extender?
With a properly specified extender and correct cabling, you should not see visible quality loss within the supported resolution and distance limits. The bigger issue is usually compatibility or signal stability, not image degradation in the traditional sense.
The Atlona AT-AVA-EX70C-KIT supports 4K/UHD at 60 Hz with 4:2:0 chroma up to 130 feet and 1080p at 60 Hz up to 230 feet over Cat6 or Cat6A. It also includes EDID filtering and clock stretching, which help prevent handshake issues and unsupported resolution problems that can cause blank screens, intermittent sync, or unstable performance. HDCP 2.2 support also matters for protected 4K content.
For buyers, the key tradeoff is matching the extender to the signal format and cable distance. If you need full 4K performance over longer distances, check the exact chroma and frame rate requirements. In conference rooms and classrooms sending presentations, signage, and standard 4K content, this type of extender is a practical and reliable solution.
How can I extend HDMI over a longer distance without running a very long HDMI cable?
The most common professional method is to use an HDMI over Cat6 extender kit. Instead of pulling a long HDMI cable, you place a transmitter at the source and a receiver at the display, then connect them with Category cable. This is often easier to install, easier to service, and more reliable over distance.
The Atlona AT-AVA-EX70C-KIT is designed for that setup. It extends HDMI signals over a single Cat6 or Cat6A cable and supports 4K/UHD 60 Hz 4:2:0 up to 130 feet or 1080p up to 230 feet. Because the transmitter powers the receiver remotely over HDBaseT, you do not need a separate power supply at the display location, which can simplify behind-display installations.
This approach is especially useful in rooms where the source sits at a lectern, conference table, rack, or credenza and the display is mounted across the room. It is a better fit than a long passive HDMI cable when cable path, distance, or service access is a concern.
Is this a good extender kit for conference rooms and classrooms?
Yes, this extender kit is well suited for conference rooms and classrooms where a source device needs to feed a front-of-room display or projector over a moderate distance. Its feature set aligns with common room designs used in corporate, higher education, and government environments.
The Atlona AT-AVA-EX70C-KIT supports 4K/UHD 60 Hz 4:2:0 transmission up to 130 feet and 1080p up to 230 feet over Cat6 or Cat6A. It also carries bidirectional RS-232 and IR, which is useful if the room design includes control of the remote display or source equipment. The remote power architecture is another practical advantage because the transmitter powers the receiver across the category cable, reducing the need for electrical access behind the display.
This is a strong fit for point-to-point AV extension from a room PC, switcher, or laptop input system to a single display. If a project requires signal distribution to multiple displays, switching among many rooms, or AV over a network, a different category of solution would be more appropriate.
What maximum distance does the Atlona AT-AVA-EX70C-KIT support?
The Atlona AT-AVA-EX70C-KIT supports up to 130 feet for 4K/UHD video at 60 Hz with 4:2:0 chroma and up to 230 feet for 1080p video at 60 Hz. Those distances are based on using a single Category 6 or 6A cable between the transmitter and receiver.
For buyers, the important detail is that resolution affects distance. If your application is standard Full HD in a classroom or meeting room, you get significantly more reach. If you are extending 4K/UHD content, the supported range is shorter but still appropriate for many point-to-point room installations. The kit is intended for dependable AV extension within those published limits rather than very long-haul transport.
To get the best results, proper cable termination and quality cabling matter. This model includes an integrated HDBaseT link test, which helps confirm cable and termination quality during installation. That is especially helpful in commercial projects where signal reliability and fast commissioning are priorities.
Does the receiver need its own power supply at the display location?
No, the receiver does not require a separate local power supply. The Atlona AT-AVA-EX70C-KIT uses remote power over HDBaseT, so the transmitter supplies power to the receiver through the same Cat6 or Cat6A cable used for signal transmission.
This is especially useful when the receiver is mounted behind a flat panel, near a projector, or inside a hard-to-access display location where adding power would increase labor or require an electrician. In conference rooms, classrooms, and public sector spaces, reducing the number of powered devices at the display end can simplify installation and improve serviceability.
The main benefit is cleaner infrastructure, not just convenience. Fewer power supplies can mean fewer failure points and less clutter behind the display. The tradeoff is that the system is designed as a matched transmitter-receiver kit, so installers should use it within the manufacturer’s intended architecture rather than mixing power expectations across unrelated extender endpoints.
Can this extender pass control signals like RS-232 and IR as well as video?
Yes, the Atlona AT-AVA-EX70C-KIT passes bidirectional RS-232 and IR in addition to HDMI video and embedded multi-channel audio. That means it can support remote control communication between equipment at the source end and the display end without needing separate control cabling.
This matters in professional AV because many rooms need more than just picture transmission. For example, a control system may need to power a display on and off, switch inputs, or send commands to a source device located elsewhere in the room or rack. Bidirectional capability gives more flexibility because commands can travel in either direction as needed by the system design.
This is most beneficial in integrated classrooms, conference rooms, and residential media spaces where clean cable paths are important. Buyers should note that while RS-232 and IR transport are included, this is still a point-to-point extender kit, so it is best for single-path control extension rather than complex routed control across a larger AV network.
What kinds of cable and installation practices are best for this HDBaseT extender kit?
This extender kit is designed to run over a single Category 6 or Category 6A cable, and using the correct cable type with proper terminations is important for stable performance. In professional AV installations, cable quality, termination consistency, and avoiding unnecessary splices all help reduce signal issues.
The Atlona AT-AVA-EX70C-KIT includes an integrated HDBaseT link test, which is valuable during setup because it lets installers verify cable and termination quality more quickly. It also has EDID filtering and clock stretching to improve compatibility and signal stability, especially when displays and sources negotiate video formats.
For best results, use solid installation practices appropriate to structured cabling environments, particularly in classrooms, boardrooms, and government facilities where reliability matters. This kit also includes mounting brackets for surface installation, making it practical to secure behind displays or inside furniture. Buyers planning a simple point-to-point HDMI over Cat6 run will benefit most, while more complex routed systems may need different infrastructure.
Who should choose the Atlona AT-AVA-EX70C-KIT instead of another type of AV extension solution?
This kit is best for users who need a reliable point-to-point HDMI extension path with control support and minimal display-end power requirements. It is a strong choice when a single source must connect to a single remote display in a classroom, conference room, training room, or residential media setup.
The Atlona AT-AVA-EX70C-KIT supports 4K/UHD 60 Hz 4:2:0 up to 130 feet and 1080p up to 230 feet over Cat6 or Cat6A, while also passing bidirectional RS-232 and IR. Its remote power design simplifies installation because the transmitter powers the receiver over HDBaseT. Diagnostic and compatibility features such as link testing, EDID filtering, and clock stretching make it well suited to managed AV environments where uptime matters.
Choose this type of extender if your priority is stable room-to-display connectivity over structured cabling. Consider another solution if you need switching between many sources, distribution to multiple displays, or network-based AV transport across a larger campus or enterprise deployment.
