What does B-Stock mean for this controller?

B-Stock means this P3-175 is fully functional and meets all specifications; it may have minor cosmetic imperfections on the steel and aluminum chassis or finish, but performance and reliability are unaffected.

Can I expand this system if my rig grows?

Yes—the P3-175's pixel and fixture capacity both expand by adding additional P3-175 units to the system without replacing the existing hardware.

What control protocols and inputs does it support?

The P3-175 accepts 256 universes of Art-Net/sACN, DMX, Kinesys K2, and Full HD video input via HDMI/NDI, and can be controlled from any standard monitor (VGA, DVI, HDMI, or DisplayPort) paired with USB keyboard and mouse.

What is the system latency and processing depth?

The P3-175 delivers 2-frame system latency and 16-bit per-color (48-bit per pixel) processing depth, providing smooth, responsive control over large fixture and pixel networks.

How does this fit into a typical live or studio install?

The 1U rackmount design (19.0" W × 1.75" H × 13.5" D) integrates seamlessly into standard server racks, making it ideal for touring rigs, venue installations, and production facilities running complex lighting and projection setups.

Do I pay sales tax on this order?

We collect sales tax only on orders shipped to California. Orders shipped to any other US state are charged $0 sales tax at checkout when you buy direct from our website. On this item that is roughly $485 less out the door than the same listed price at a national retailer or on a marketplace. Marketplaces such as eBay, Reverb and Amazon collect sales tax in nearly every state as marketplace facilitators no matter who the seller is, so the same item at the same price costs less bought direct. Free US shipping and 30-day returns are included. Some states ask buyers to self-report use tax on out-of-state purchases.

Martin P3-175 System Controller

The P3-175 is a professional-grade lighting control system designed for complex architectural and entertainment lighting installations. This compact 1U rackmount processor delivers serious processing power in a footprint that fits seamlessly into standard server racks, making it the workhorse controller for mid-to-large scale projection and lighting rigs.

Processing Power & Scalability

The P3-175 handles 520,000 pixels and up to 2,000 fixtures with 16-bit per-color (48-bit per pixel) processing depth and 2-frame system latency—essential specs for smooth, responsive control over demanding installations. Both pixel and fixture capacity expand by adding additional P3-175 units, allowing the system to grow without replacing core hardware.

Connectivity & Input Flexibility

Full support for 256 universes of Art-Net/sACN input alongside DMX, Kinesys K2, and HDMI/NDI video input ensures compatibility with industry-standard control protocols and live video sources up to Full HD (1920×1080). The controller accepts input from any standard monitor (VGA, DVI, HDMI, or DisplayPort) paired with USB keyboard and mouse for intuitive operation.
