# Routing through HOLOPLOT Processors

Third-party speakers are routed through external HOLOPLOT Processors, each of which supports up to **256 audio channels**. Routing is handled manually by the user inside the Processor Routing Matrix. You assign audio inputs to the appropriate channels and align them with your defined speaker positions in Plan. To access the Processor Routing Matrix, click the ![](/files/yHWyLawANgGYnQ8cvaaH) from the processor info panel.
