EA‑1
→ CORE 1
CORE 1 is usually the closest current starting point. CORE Lite is reserved for especially small, bundle-style designs.
The practical EA-to-CORE starting point
These are planning equivalents—not automatic one-for-one replacements. A dealer must audit the project file, drivers, audio routes and physical connections before selecting the new controller.
EA‑3
→ CORE 3
The closest family match when the system uses multiple audio paths and a moderate mix of IR, serial, contact and relay control.
EA‑5
→ CORE 5
The rack-mount choice for a large project with the highest controller load, audio distribution and physical control I/O.
The EA family
EA controllers are the previous Control4 Entertainment and Automation generation. They can still appear in working systems, but they are no longer the current controller family.
EA‑1
C4-EA1
Original fit: one entertainment room or a smaller Control4 system.
- 1080p HDMI on-screen navigator
- 1 HDMI audio output
- 4 IR outputs and 2 shared serial outputs
- Built-in Zigbee control
Keep or upgrade? Keep if stable and correctly sized; assess CORE 1 when reliability, compatibility or expansion changes.
EA‑3
C4-EA3 / C4-EA3-V2
Original fit: a mid-size home needing more audio and control ports.
- 1080p HDMI on-screen navigator
- 3 audio outputs and 2 audio inputs
- 6 IR, 3 shared serial, 1 contact and 1 relay
- PoE+ and dual Ethernet connections
Keep or upgrade? CORE 3 is the normal evaluation point, but existing drivers and every physical port must be mapped first.
EA‑5
C4-EA5
Original fit: a large home with centralized audio and extensive control wiring.
- 1080p HDMI on-screen navigator
- 5 audio outputs and 4 audio inputs
- 8 IR, 4 serial, 4 contacts and 4 relays
- 1U rack design with built-in Ethernet switch
Keep or upgrade? CORE 5 is the natural current-family comparison for a large rack and heavy project load.
The current CORE family
CORE adds newer processing, 4K on-screen navigation on CORE 1/3/5, Ryff high-resolution audio, secure boot and built-in OvrC Pro for professional remote monitoring and service.
CORE Lite
C4-CORE-LITE
Best for: a very small Control4 project—officially recommended for about 20 devices and 2 rooms.
- 1080p HDMI on-screen navigator
- 1 HDMI audio zone
- 3 IR outputs and 1 shared serial output
- Compact, fanless bundle-oriented platform
Client language: The entry CORE—not the automatic replacement for every EA‑1.
CORE 1
C4-CORE1
Best for: a single entertainment room, apartment or smaller whole-home system.
- 4K at 60 Hz HDMI on-screen navigator
- 2 audio outputs: HDMI and digital coax
- 4 IR and 2 shared serial outputs
- PoE+, dual Ethernet and fanless design
Client language: The full-featured small-project controller and usual EA‑1 upgrade conversation.
CORE 3
C4-CORE3
Best for: a mid-size home with multiple audio zones and mixed wired control.
- 4K at 60 Hz on-screen navigator
- 4 audio outputs and 1 digital audio input
- 6 IR, 3 serial, 1 contact and 1 relay
- Zigbee, Z-Wave, PoE+ and dual Ethernet
Client language: The balanced whole-home choice when CORE 1 lacks the audio or I/O headroom.
CORE 5
C4-CORE5
Best for: a large custom home with hundreds of devices, centralized audio and extensive control I/O.
- 4K at 60 Hz on-screen navigator
- 7 audio outputs and 2 audio inputs
- 8 IR, 4 serial, 4 contacts and 4 relays
- 4 GB RAM, Zigbee, Z-Wave and 1U rack chassis
Client language: The flagship controller for the largest system—not an upgrade chosen only for bragging rights.
All seven models side by side
| Model | Status | On-screen video | Audio | Control I/O | Best planning fit |
|---|---|---|---|---|---|
| EA‑1 | Legacy | 1080p | 1 out | 4 IR / 2 serial | Existing small or one-room system |
| EA‑3 | Legacy | 1080p | 3 out / 2 in | 6 IR / 3 serial / 1 contact / 1 relay | Existing mid-size system |
| EA‑5 | Legacy | 1080p | 5 out / 4 in | 8 IR / 4 serial / 4 contact / 4 relay | Existing large rack system |
| CORE Lite | Current | 1080p | 1 HDMI zone | 3 IR / 1 serial | Very small project; about 20 devices / 2 rooms |
| CORE 1 | Current | 4K @ 60 Hz | 2 out | 4 IR / 2 serial | One room or smaller whole-home project |
| CORE 3 | Current | 4K @ 60 Hz | 4 out / 1 in | 6 IR / 3 serial / 1 contact / 1 relay | Mid-size whole-home project |
| CORE 5 | Current | 4K @ 60 Hz | 7 out / 2 in | 8 IR / 4 serial / 4 contact / 4 relay | Large custom project and main rack |
Specifications checked against official Control4 data sheets on July 13, 2026. Audio counts include HDMI where listed. Serial ports may share terminals with IR outputs. Final compatibility and availability must be confirmed for the actual project.
When does an EA upgrade make sense?
New rooms, lighting, shades, security, audio or video can push an older controller beyond the role it was originally sized to perform.
Intermittent restarts, storage problems or repeated instability should be diagnosed before replacement—not ignored or blamed on age alone.
4K on-screen navigation, newer processing, more audio paths, current radios, secure boot and built-in OvrC Pro can justify the project.
Important: A controller swap is not a simple retail-box replacement. Control4 programming uses Composer Pro and should be handled by an authorized professional who can back up the project, map every connection, update compatible drivers and test the complete system after migration.
What a proper controller migration includes
Document the controller, OS version, licenses, drivers, Zigbee role, audio routes and every physical connection.
Select the CORE model from the real workload, move the project and reconnect IR, serial, contacts, relays, audio and networking.
Verify lights, shades, locks, thermostats, AV, remotes, touchscreens, scenes, app access, notifications and remote service.
A simple client explanation
“EA is the older controller family and CORE is the current family. We do not replace an EA controller just because it is older. We first check whether it is healthy, compatible and large enough. If the system needs more performance, newer features or long-term serviceability, we choose the CORE model from the actual audio, control and device plan.”
