An SRTLA server, with the studio behind it.
If you stream from an open bonding rig, its SRTLA stream needs somewhere to land, and that receiver decides what happens when your signal drops. Lumbus Studio is that place: a private machine in your region that takes bonded SRTLA in, watches the feed once a second, and sends your programme to every platform.
What SRTLA is, in one paragraph.
SRTLA is SRT with link aggregation: the rig sends one stream over several connections at once and the receiver puts it back together. Open bonding rigs use it, and each one needs an SRTLA receiver at the far end. With Lumbus, the receiver is your own studio machine, so the bonded stream arrives where the scenes, the automatic Be right back and your platforms already are.
Point your rig at it.
- 01Take a Studio planYour studio’s address takes SRT, RTMP and SRTLA; the SRTLA row in your dashboard shows the one for your rig.
- 02Enter it on the rig and test off-airEach destination tests with colour bars before anything goes live.
- 03Add your platforms and go liveStudio makes a copy for each platform on the machine — up to 5 at once on Studio, 20 on Studio Pro.
What the studio does with your feed.
- Stay live. Signal drops? Viewers see “Be right back”, and Live comes back by itself.
- Stream to every platform. Twitch, Kick, YouTube, TikTok and more, all at once, from one stream.
- Run it from your phone. Change what viewers see with one thumb, in a browser or the app.
- Your machine, near you. Your studio’s own computer online, in the part of the world you pick. Move it when you travel.
Two plans, monthly, cancel any time.
No Unit required, and no Lumbus Connect pack: your rig does the bonding, the studio receives it.

Lumbus Connect or SRTLA?
Two ways to bond. Lumbus Connect is the bonding service the Lumbus Units use, bought in packs. SRTLA is the open protocol your own rig uses, and Studio takes it in with no Connect pack at all — you pay for the studio, and your connections are billed by whoever provides them. Lumbus SIMs can go in your rig too, delivered for you to fit.
Technical detailsWhat it takes in, hours on air, and where your studio runs
- What it takes in
- SRT (preferred), RTMP, or bonded SRTLA from an open bonding rig · H.264 and H.265 at the bitrate your connection carries · one feed in on Studio; on Studio Pro a second Unit stands by on a backup feed and takes over the moment the first stops · previews, monitoring and every output are made on the machine.
- Hours on air
- Hours on air are counted per destination: an hour sent to three platforms is three hours. Hours above 1080p count more, because they carry more video — 1440p60 counts double and 4K60 four times. Nothing is ever cut off when an allowance runs out: you get a notice at 80%, 90% and 100%, and more hours are added from Plan & add-ons.
- Where it runs
- On a private machine in the region you pick — London, Frankfurt, US East, US West, Singapore or Tokyo — so the hop to it is short. Move it between trips from Your studio; your scenes and destinations come with it. On a schedule it sleeps when you are done and wakes before you start, never while anything is streaming.
Questions
Do I need a Lumbus Unit to use the SRTLA server?
No. Studio takes bonded SRTLA from an open bonding rig, and SRT or RTMP from anything else. A Lumbus Unit is optional.
Can I send plain SRT instead of SRTLA?
Yes. SRT is the preferred way in, RTMP works too, and SRTLA is there for rigs that bond their own connections.
What does Studio do when my signal drops?
It shows viewers a “Be right back” screen instead of a frozen picture, and switches back to Live by itself when your signal returns. Every platform stays connected the whole time.
Technical detailsThe full answer, in detail
It watches your feed once a second. Weak for a few seconds and you get your Low bitrate scene; gone, and you get Be right back. A frozen or black picture arriving at a healthy bitrate is seen too — shown as a word, and sent to Be right back if you turn that rule on. Live comes back by itself once the signal has held for a few seconds — with a margin, so it never flaps. Viewers see a designed scene, not a frozen frame, and every platform stays connected the whole time.
Is there a bitrate limit on what I send?
Send at the quality your connection can carry. Studio makes its own output from it, so changing the quality viewers get never restarts your stream.
Technical detailsThe full answer, in detail
Send H.264 or H.265 at the bitrate your connection carries — 4 to 8 Mbps is the usual range at 1080p60, more for 4K. Studio makes its own output from that one feed (1080p60 on Studio; 1440p60 and 4K60 on Studio Pro for YouTube and custom RTMP — Twitch, Kick and TikTok take 1080p at most), so a change of output quality never restarts anything mid-stream.
