NovaStar MCTRL660 PRO LED controller
The NovaStar MCTRL660 PRO connects HDMI, DVI or 3G-SDI sources to an LED display system. Six Gigabit Ethernet ports and two 10G optical ports support local receiver-card connections and fiber-based signal distribution. Sending-card and fiber-converter operating modes let it serve different positions in a rental or fixed-installation signal chain.
Resolution and color-depth planning
HDMI and DVI support up to 1920 × 1200 at 60 Hz with 8-bit input. The linked V1.0.0 specification distinguishes this from 10-bit/12-bit operation: the standard program supports 1920 × 960 at 60 Hz, while 1920 × 1080 at 60 Hz requires customized sending-card and receiving-card programs and A8s receiving cards. Verify the installed programs before designing a higher-bit-depth setup.
| Parameter | Specification |
|---|---|
| HDMI input | 1 × HDMI 1.4a; HDCP 1.4 |
| DVI input | 1 × single-link DVI |
| HDMI/DVI at 8-bit | Up to 1920 × 1200 at 60 Hz with the standard program |
| HDMI/DVI at 10-bit or 12-bit | Standard program: 1920 × 960 at 60 Hz; customized programs with A8s: 1920 × 1080 at 60 Hz |
| HDMI/DVI custom resolutions | 3840 × 600 at 60 Hz horizontally; 600 × 3840 at 60 Hz vertically |
| 3G-SDI input | 1; supports 1920 × 1080 at 60 Hz and 1280 × 720 at 60 Hz; input resolution cannot be set through the controller |
| Loop outputs | 1 × HDMI LOOP; 1 × DVI LOOP; 1 × 3G-SDI LOOP |
Signal routing, monitoring and setup
In sending-card mode, the Ethernet and optical outputs can carry the same image. OPT1 is the primary optical connection and OPT2 is its backup. In fiber-converter mode, the device converts between the optical connections and the six Ethernet ports in either direction.
The controller provides input monitoring, web control, automatic screen configuration, image flipping, configuration backup/recovery and pixel-level brightness and chroma calibration. Independent RGB gamma adjustment helps tune low-grayscale color balance. The specification lists low-latency operation below one frame (up to 10 lines); confirm the complete receiving-card configuration when commissioning the screen.

Frequently Asked Questions
What is the maximum resolution of the MCTRL660 PRO?
At 8-bit, HDMI and DVI support 1920 × 1200 at 60 Hz with the standard program. The specification also lists custom 3840 × 600 and 600 × 3840 modes at 60 Hz. These wide/tall modes do not mean full 4K UHD input support.
Can the MCTRL660 PRO run 10-bit or 12-bit video at 1080p60?
V1.0.0 specifies 1920 × 960 at 60 Hz with standard programs. Reaching 1920 × 1080 at 60 Hz at those color depths requires customized sending-card and receiving-card programs and A8s receiving cards.
Can the MCTRL660 PRO work as a fiber converter?
Yes. In fiber-converter mode it converts between the optical ports and the six Gigabit Ethernet ports. OPT1 is the primary optical port and OPT2 provides backup.
Does it provide an HDMI monitor output?
Yes. The separate HDMI MONITOR output operates at 1920 × 1080 at 60 Hz. The specification describes proportional scaling for monitoring when the input resolution exceeds that monitor resolution.
Where are the MCTRL660 PRO specification and user manual?
Both original PDFs are linked in the Download Specification section above. Use them to check input timing, color-depth conditions, operating modes, cabling and configuration before installation.
