MCTRL660 PRO LED Display Controller
Flagship independent master controller with Genlock synchronization, 3G-SDI broadcast input, 6× Gigabit Ethernet outputs, HDMI 1.4, optical fiber connectivity, and OLED knob HMI — supplied by Excelled, a trusted LED screen manufacturer for global B2B buyers.

What Is the NovaStar MCTRL660 PRO LED Display Controller?
MCTRL660 PRO LED display controller is NovaStar’s flagship independent master controller, powered by the Nova G4 processing engine with broadcast-grade Genlock synchronization. It occupies the same compact 440×258×55.3 mm chassis as the MCTRL660 but adds 3G-SDI input, 6× Gigabit Ethernet outputs, HDMI 1.4, optical fiber output, and an OLED display — making it the definitive choice for live broadcast, multi-camera studio, and large-scale LED display deployments requiring frame-accurate synchronization across multiple screens.
The MCTRL660 PRO accepts 1× 3G-SDI, 1× HDMI 1.4, and 1× DVI inputs, with Genlock input and Genlock loop for studio sync. Six RJ45 Gigabit Ethernet ports independently drive up to 650,000 pixels each, delivering approximately 3.9 million pixels total loading capacity — nearly double the MCTRL660’s 2.3M. The optical fiber output enables lossless signal transmission over kilometers for sports LED display and large-venue deployments. With the OLED knob HMI, field technicians can navigate menus, switch inputs, and run test patterns directly at the controller.

Genlock Sync & 3G-SDI — Built for Live Broadcast
The MCTRL660 PRO’s defining upgrades over the MCTRL660 are Genlock synchronization and 3G-SDI input — two features essential for multi-camera broadcast environments. Genlock ensures all connected LED screens refresh in perfect frame alignment with the studio sync generator, eliminating tearing, stuttering, and scan-line artifacts when cameras capture the screen. The 3G-SDI input accepts professional broadcast signals up to 1080p@60Hz directly from cameras, switchers, and broadcast decks — no external converters required. This makes the MCTRL660 PRO the controller of choice for rental LED display in broadcast TV studios, esports arenas, and live event productions.

How Genlock Works in the MCTRL660 PRO
- Genlock IN: Receives the studio Black Burst or Tri-Level sync signal from the master sync generator — all connected PRO units lock to this reference.
- Genlock LOOP: Passes the sync signal to the next MCTRL660 PRO in the chain — no external distribution amplifier needed for multi-screen setups.
- Frame Lock: Each PRO unit’s output refresh is phase-locked to the incoming sync — every screen refreshes at the exact same moment, frame-by-frame.
- 3G-SDI + Genlock Combined: Camera feed enters via SDI, sync is provided via Genlock — the entire signal chain from camera to LED wall is synchronized.

OLED Display & Optical Fiber
The OLED display provides higher contrast and wider viewing angles than the standard MCTRL660’s LCD — readable in bright stage environments. The optical fiber output transmits the full video signal over single-mode fiber for up to 10km without signal degradation, eliminating the Cat6 cable length limit for large-venue control room LED video wall deployments and outdoor stadium installations.
How to Connect and Cascade Multiple MCTRL660 PRO Units
Video signal flow: Camera/Switcher → 3G-SDI or DVI/HDMI input → MCTRL660 PRO Nova G4 engine encodes → 6× CAT6 Ethernet outputs + 1× Optical Fiber → receiving cards. With SDI + HDMI + DVI triple input and Genlock loop, the PRO integrates seamlessly into broadcast infrastructure without external converters or distribution amplifiers.

Six-Port Configuration Modes
- Independent Mode: Each of the 6 ports drives its own screen segment — ideal for complex stage designs with multiple LED surfaces.
- Redundancy Mode: Ports paired as primary + backup — failover within 0.5 seconds on link loss. With 6 ports, configure 3+3 or 4+2 redundancy schemes.
- Mixed Mode: Combine independent segments with redundant pairs — e.g., 4 ports for a main screen (2+2 redundant) + 2 ports for side screens.
Optical Fiber + UART Cascade
The optical fiber output bypasses Ethernet distance limitations — send the full pixel stream over kilometers of single-mode fiber to remote receiving cards. Up to 20 MCTRL660 PRO units cascade via UART, managed from a single PC. At approximately 3.9M pixels × 20 units = 78 million pixels theoretical maximum, this handles the largest church LED screen and stadium deployments.
MCTRL660 PRO Setup with NovaLCT — Step by Step
Full configuration — Genlock setup, SDI input selection, 6-port mapping, Gamma curves, and optical fiber routing — uses NovaLCT (NovaStar LED Control Toolkit). This workflow is based on NCE training and broadcast integration field data.
- Physical Connection: USB Type-B to PC. Connect SDI/HDMI/DVI from source. Connect Genlock IN from sync generator. CAT6 from 6× RJ45 + optical fiber to receiving cards. AC power.
- Launch NovaLCT: Software auto-detects the MCTRL660 PRO. Verify serial number and firmware.
- Select Input Source: Choose 3G-SDI, HDMI 1.4, or DVI. SDI supports broadcast standard 1080p@60Hz. HDMI supports HDCP 1.4 and 10bit/12bit deep color.
- Configure Genlock: Set sync source in NovaLCT — Black Burst or Tri-Level. Verify lock status indicator turns green. Set Genlock LOOP to output mode for daisy-chaining.
- Configure Six-Port Mapping: Assign each RJ45 port to its screen segment. Enable port-pair redundancy for broadcast-critical links. Route to optical fiber output if applicable.
- Load RCFGX File: Each LED cabinet requires its .rcfgx configuration file — Excelled pre-loads these before shipping.
- Calibration + 10bit Gamma: Use NovaCLB for calibration. Configure 10bit Gamma in NovaLCT for smooth grayscale on fine-pitch displays.
- OLED Verification: After configuration, use the OLED menu to verify Genlock lock status, all 6 port connections, and input source — a secondary confirmation independent of NovaLCT.
MCTRL660 PRO Common Issues & Diagnostic Procedures
Based on field service data from broadcast and rental deployments. For complex issues, contact Excelled‘s engineering team.
Q1 Genlock not locking — studio sync generator connected but no lock
Diagnosis: Sync signal format mismatch or Genlock LOOP not terminated.
Resolution: Verify the sync generator outputs Black Burst or Tri-Level compatible with MCTRL660 PRO. Check Genlock LOOP is either connected to the next unit or properly terminated. In NovaLCT, verify Genlock mode matches the sync signal type. Check OLED: Menu → Device Info → Genlock Status should show “Locked.”
Q2 3G-SDI input shows no signal — camera connected but screen black
Diagnosis: SDI input not selected or cable standard mismatch.
Resolution: In NovaLCT or OLED menu, verify input source is set to 3G-SDI (not HDMI or DVI). Confirm camera outputs 3G-SDI (not HD-SDI or 12G-SDI). Check SDI cable quality — 3G-SDI requires 75-ohm rated cable. Try a shorter cable to rule out signal loss.
Q3 Optical fiber output not working — Ethernet ports work fine
Diagnosis: Fiber module not installed, fiber type mismatch, or port not enabled in software.
Resolution: Verify the SFP optical module is properly seated. Confirm single-mode fiber is used (not multi-mode for long distances). In NovaLCT, enable optical fiber output in the port mapping settings. Check fiber connectors are clean and properly aligned.
Q4 HDMI 1.4 source not displaying — 4K content or HDCP issue
Diagnosis: HDMI 1.4 bandwidth limitation or HDCP 2.2 incompatibility.
Resolution: HDMI 1.4 max input is 1920×1200@60Hz — 4K sources need downscaling. HDCP 1.4 is supported but HDCP 2.2 is not — use non-HDCP or HDCP 1.4 content. Switch to DVI input to isolate the HDMI-specific issue.
Q5 One of six Ethernet ports not outputting — others working
Diagnosis: Individual port configuration, cable fault, or receiving card issue on that port’s chain.
Resolution: In NovaLCT, verify the non-working port is mapped to a screen segment. Check the CAT6 cable and receiving card on that specific chain. Use OLED: Network Settings → verify all 6 port IPs are visible. Swap cables between a working and non-working port to isolate the fault.
NovaStar Controller Comparison: MCTRL300 vs MCTRL600 vs MCTRL660 vs MCTRL660 PRO
NovaStar’s MCTRL series spans from 1.3M to 8M+ pixels. The MCTRL660 PRO is the broadcast-grade flagship: Genlock sync, SDI input, 6-port Ethernet, and optical fiber — purpose-built for multi-camera studios and large-venue sports LED display.
