Frequently Asked Questions
What is remote audio mixing?
It’s large format console mixing, routing, and monitoring without the on-site footprint. Our engineers manage your full mix remotely, saving space, travel costs, and setup time while delivering the same clarity and control you’d expect from an engineer with a console in a mixing suite.
Is ARCA secure?
Yes. ARCA runs on encrypted connections and monitored networks. Your audio stays clean, private, and uninterrupted.
What kind of internet do we need?
A reliable wired connection with consistent bandwidth is ideal. We’ll help assess your network ahead of time and make sure it’s show-ready.
Can we connect multiple locations at once?
Definitely. ARCA was built to handle multi-site events. Whether you’ve got a presenter in Paris, a panel in Toronto, and a host in New York, we’ll make them sound like they’re in the same room.
Why should we choose ARCA?
Because it’s built for the way shows actually happen. ARCA was designed by engineers who mix live events every day, not by a team in a lab. It’s compact, travel-ready, and powerful enough to handle full broadcast mixes without the need for an on-site footprint. Whether you’re supporting a global town hall, a touring production, or a remote studio feed, ARCA gives you the same control, clarity, and reliability you’d expect on site, just with more flexibility.
