How Many Inputs and Outputs Do You Actually Need in a Matrix Switcher?
The most common matrix switcher mistake is sizing for today instead of the next three years. Here is a straightforward way to work out the right channel count before you buy.
Key takeaways
- Count every source and display you have today, including spares and test feeds.
- Add at least 2 spare inputs and 2 spare outputs for growth — expansion later usually means a new box, not new ports.
- An 8×8 covers most small control rooms; a 16×16 suits larger broadcast or multi-zone venues.
- If you also need preview of every input at once, a multiviewer/matrix combo saves a separate box.
Step 1: count your real sources
List every camera, playback device, laptop input, graphics feed and backup source that needs to reach a screen or recorder — not just the ones in daily use. Spare or backup sources still need a matrix input if they might be routed live during a failure.
Step 2: count your real destinations
Do the same for outputs: displays, confidence monitors, recorders, streaming encoders and any secondary control room. Each independent destination needs its own output port.
Step 3: add headroom, not a full second system
Because most matrix switchers ship in fixed sizes, buying exactly what you need today usually means buying again in a year. Sizing one tier up — or picking a chassis with a couple of spare ports — is almost always cheaper than adding a second, separate matrix later.
Matching the count to a real product
Small control rooms and single-venue routing typically fit the MSS0811 8×8. Larger broadcast setups, multi-zone venues or projects needing redundant power step up to the MSS1611-S 16×16 or the compact 1RU 16×16 seamless matrix. If your team also needs to preview every source at once on one screen, the MMV1630 runs as a 16-channel multiviewer and a 16×16 matrix in a single chassis.
