Frequently Asked Questions
What kinds of events do you support?
Corporate meetings, live event broadcasts, global town halls, hybrid keynotes, multi-camera streams, creative agency rollouts, product launches, you name it. If it needs live sound that works under pressure, we’re in.
What is ARCA?
ARCA is our remote audio engine: a powerful, carry-on-sized rig that gives you 128 channels of broadcast-quality mix control over IP. It’s small enough to carry on a plane and strong enough to anchor an international broadcast.
Can you plug into our existing workflow?
Yes. Whether you’re working with venue AV, broadcast trucks, studio teams, or in-house technical staff, we sync up fast and play nice. Our gear is flexible. Our engineers are even more so.
What if something goes wrong during the show?
Lossless audio is crucial in live events. There’s no room for dropouts, degradation, or guesswork. That’s what redundancy and safeguards are for. Our systems are designed with backups on top of backups, and we’re monitoring every second from start to stop. If something hiccups, we’re already fixing it.
