Frequently asked questions
Why are these products both called 'coupler' but so different?
In rigging, a coupler joins trussing tubes mechanically. In audio, a coupler distributes signals electrically. These serve entirely separate industries despite sharing terminology.
Can I use the rigging coupler for audio applications?
No. The Martin Super Lightweight Half Coupler is designed solely for aluminum trussing mechanical connections. It has no audio signal path or electrical properties.
Which coupler is better for my needs?
If your work involves stage setup, trussing, or rigging, choose Product A. If you need audio signal routing, metering, or parallel processing in a studio or live sound context, choose Product B. They solve completely different problems.
