Frequently asked questions
Are these products interchangeable or related?
No. Product A is a lighting rigging coupler designed exclusively for Martin VDO Sceptron and VDO Fatron stage lighting fixtures. Product B is an audio signal coupler for studio and live sound applications. They share a manufacturer and similar product naming but serve completely different functions.
Which product is suitable for professional touring installations?
Product A is purpose-built for touring stage lighting installations, where its low-profile design helps minimize fixture-to-truss distance in complex rigging scenarios. Product B is designed for audio signal routing in studio and live sound contexts, not lighting infrastructure.
What are the key technical differences between these products?
Product A is a mechanical rigging device that slides into lighting fixture profile channels using an M6 bolt. Product B is an electrical signal coupling device with balanced audio connectors, impedance matching, and passive circuit topology designed to maintain audio signal integrity across multiple signal paths.
Do I need external power for either product?
Product A requires no power—it is purely mechanical. Product B is a passive audio circuit that also requires no external power, operating through electrical impedance matching and isolation.
