Martin P3-175 System Controller B-Stock
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.

Frequently Asked Questions
What does B-Stock mean for this unit?
B-Stock means this P3-175 is fully functional with no defects in operation. It may have minor cosmetic imperfections on the chassis or finish from handling or display, but performance and reliability are identical to new.
Can I expand the P3-175 if my rig grows?
Yes. You can add additional P3-175 units to expand both pixel and fixture capacity without replacing the original controller, allowing your system to scale as your installation grows.
What protocols and input formats does it support?
The P3-175 supports 256 universes of Art-Net and sACN, plus DMX, Kinesys K2, HDMI video input, and NDI protocol. It accepts Full HD video (1920×1080) and connects to any standard display monitor (VGA, DVI, HDMI, DisplayPort) with USB keyboard and mouse control.
What is the system latency?
The P3-175 delivers 2-frame system latency with 16-bit per-color processing (48-bit per pixel), ensuring smooth, responsive control with minimal perceptible delay in live and recorded environments.
How does this fit into a live or touring setup?
At 1U in a standard 19-inch rackmount chassis and weighing only 7.7 lbs, the P3-175 slides into any server rack, tour case, or mobile installation. Its industrial steel and aluminum construction handles road vibration and temperature swings from 32°F to 122°F, and it integrates with industry-standard protocols so it plays well with lighting consoles, media servers, and control surfaces you may already own.
Do I pay sales tax on this order?
Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. At a typical 7% rate that is an estimated $485 less at checkout than the same listed price on a marketplace, which collects sales tax as the facilitator in most states. Buyers remain responsible for any use tax their state applies. Free US shipping and 30-day returns are included.
