MCTRL 660 LED Controller — Professional NovaStar Sending Card for Mid-to-Large LED Displays
The MCTRL660 is NovaStar’s professional-grade LED sending card, engineered for rental staging, broadcast studios, and fixed installations. A single unit drives up to 2.3 million pixels across 4 Gigabit Ethernet ports with custom resolutions up to 3840 pixels. Supporting 10-bit and 12-bit color depth, pixel-level brightness and chroma calibration, hot backup verification, and USB cascading of up to 20 units, it delivers the reliability and image quality that AV professionals demand. As a leading LED screen manufacturer, LEGIDATECH supplies the MCTRL660 factory-direct with 3-year warranty and pre-shipment burn-in testing.
What Is the MCTRL 660 LED Controller?
The MCTRL660 is NovaStar’s mid-to-high-end LED sending card, positioned between the entry-level MCTRL600 and the flagship MCTRL4K. It features DVI and HDMI inputs accepting up to 1920×1200@60Hz with custom resolutions extending to 3840 pixels in width. Four independent Gigabit Ethernet outputs drive up to 2.3 million pixels at 8-bit, with 10-bit and 12-bit color processing available through NovaLCT software. What truly sets the MCTRL660 apart are its professional features: hot backup verification for zero-downtime operation, pixel-level brightness and chroma calibration for factory-grade color uniformity, and support for cascading up to 20 units via USB.

Key Features of the MCTRL 660
10-bit Gamma Adjustment
Individual gamma adjustment for 10-bit and 12-bit input sources. Corrects image non-uniformity in low grayscale and white balance offset for perceptibly more accurate color than standard 8-bit controllers.
Hot Backup Verification
Device-level backup, port-to-port backup, and automatic input switchover ensure zero-signal-loss. If the primary signal degrades, the MCTRL660 switches to backup within milliseconds — critical for live broadcast.
Pixel-Level Calibration
Per-pixel brightness and chroma adjustment corrects manufacturing variance in LED modules, producing uniformly bright, color-accurate displays across the entire wall surface. Factory-grade calibration without factory hardware.
20-Unit USB Cascading
USB-A cascade links up to 20 MCTRL660 units with Genlock synchronization. Combined: 46 million pixels across 80 Ethernet ports. Auto-detected in NovaLCT with unified configuration management.
Professional Audio Integration
3.5mm audio input transmits synchronized audio to the multifunction card. Simplifies AV setups by eliminating separate audio routing for presentations and digital signage.
Industrial Build Quality
Components rated for 24/7 continuous operation. Reinforced I/O connectors tested for 10,000+ cycles. CE/FCC/RoHS certified for global compliance.

Frequently Asked Questions
What is hot backup verification and why does it matter?
Hot backup enables the MCTRL660 to maintain a redundant signal path. If the primary cable fails or signal degrades, the controller switches to backup within milliseconds. For live events and 24/7 signage, this prevents costly display blackouts.
How does the MCTRL660 compare to the MCTRL600?
The MCTRL660 adds 10/12-bit color processing, pixel-level calibration, hot backup verification, and up to 20-unit cascading (vs 10 on MCTRL600). The MCTRL600 is excellent for budget projects; the MCTRL660 is the professional choice where color accuracy and uptime directly impact revenue.
How many units can I cascade together?
Up to 20 MCTRL660 units via USB daisy-chain with Genlock synchronization. Combined capacity: 46 million pixels across 80 Ethernet ports. NovaLCT auto-detects all cascaded units for unified configuration.
Does the MCTRL660 support 10-bit and 12-bit color?
Yes. Via NovaLCT software, the MCTRL660 supports 10-bit (1,024 levels/channel) and 12-bit (4,096 levels/channel) color processing with independent gamma adjustment per RGB channel. This provides visibly smoother gradients than 8-bit controllers.
What software is used to configure the MCTRL660?
NovaLCT (LED Configuration Tool) for screen setup, receiving card mapping, and calibration. V-Can for real-time brightness, input switching, preset recall, and monitoring. Both are free downloads from NovaStar.
How is the MCTRL660 different from the MCTRL4K?
The MCTRL4K supports native 4K@60Hz input, 8.8M pixel capacity, and 16 Ethernet ports. The MCTRL660 supports 2K input and 2.3M pixels. Choose the MCTRL4K for 4K/ultra-high-res; the MCTRL660 delivers better ROI for professional 2K projects.
MCTRL 660 LED Controller: The Professional’s Guide to Mid-Tier NovaStar Sending Cards
Published: July 2026 | Author: LEGIDATECH Engineering Team
1. Why the MCTRL660 Hits the Professional Sweet Spot
For AV integrators and rental companies, the MCTRL660 occupies a unique position: all the professional features of NovaStar’s flagship line (10/12-bit color, pixel calibration, hot backup, 20-unit cascade) at roughly 60% of the MCTRL4K’s cost. For 2K-resolution projects — which represent approximately 80% of commercial LED installations — the MCTRL660 delivers identical image quality to the 4K flagship without paying for unused input bandwidth.
2. Hot Backup: The Feature That Pays for Itself
In live event production, a single display blackout can cost thousands in client refunds and reputational damage. The MCTRL660’s hot backup monitors both primary and backup signals in real time, switching proactively if the primary degrades — not just when it fails. For rental companies, this single feature often justifies the upgrade from MCTRL600 to MCTRL660.
3. Pixel-Level Calibration Without Factory Hardware
Traditionally, per-pixel brightness and chroma calibration required expensive factory equipment. The MCTRL660 brings this capability to the field via NovaLCT: technicians can calibrate individual LEDs using a standard colorimeter, correcting manufacturing variance across modules. For fine-pitch indoor displays (P2.5 and below), this transforms visual uniformity.
4. MCTRL660 in the NovaStar Ecosystem
The MCTRL660 integrates seamlessly with all NovaStar receiving cards (A5s, A8s, A10s), MCTRL and VX series controllers, and the NovaLCT/V-Can software suite. Standardized USB cascading means you can mix MCTRL660 and MCTRL4K units in the same installation. For a complete overview of NovaStar’s control system, see our Novastar control system guide.
5. Conclusion: The MCTRL 660 LED Controller Is the Professional’s Choice
For 2K LED display projects requiring broadcast-grade color accuracy, uncompromising uptime, and enterprise-level scalability, the MCTRL660 is the data-driven optimal choice. The combination of 10/12-bit processing, hot backup, and 20-unit cascade at this price point has no equivalent from competing brands.
