AV Controllers and System Processors

Computer, control surface or interface: know which job you need

This small category mixes unlike products. Control surfaces such as macro keypads and editing panels send commands but do no processing, so they need a host computer and software that supports them. Tally interfaces light a camera's on-air indicator when its source is live. Industrial interface cards connect equipment on older factory networks and work only with matching drivers and hardware. Industrial mini PCs sold as system processors are complete computers. Decide which of the four you need before you compare specifications.

Reading an embedded PC spec: processor age, memory type and ports

For the computers in this category, processor generation matters more than clock speed. Older chips such as 4th-generation Core or the Celeron J1900 predate the official Windows 11 processor list, which starts around 8th-generation Core, so confirm the advertised operating system is genuinely supported. DDR3 and DDR4 memory are not interchangeable, so check the type before planning an upgrade. Integrated graphics are fine for control and playback duties but not for heavy effects. Look for the ports your system needs, such as serial, extra Ethernet or several HDMI outputs.

Questions about AV Controllers and System Processors

Do I need a control surface if I already have a keyboard and mouse?

Not strictly. A control surface gives physical keys, dials or faders for repeated actions such as switching scenes or grading video, and it only works with software that supports it. Check software compatibility before choosing a model.

What does a tally box do?

It passes the on-air signal from a switcher to a camera or monitor so the operator and talent can see which source is live. It must match the switcher's tally output and the camera's input type.

Can a mini PC listed here run video editing?

Only light work. Models with integrated graphics and a low-power processor suit control, playback and signage, while editing and effects need a stronger processor, more memory and a dedicated graphics card. Read the processor model, not just the marketing name.
