DSP capacity

Each processor, when inserted, uses a portion of the DSP’s total processing power.

•The amount of processing power for the block is constant, unchanged by parameter settings or whether it is bypassed or not.

•Processors in the program audio input (computer/audio group and video/ audio group) processor chains (A, on figure 5-3) are active (using processor power) only when tied to an output.

•Processors in the program audio input (A) and line output (D and F) are stereo processors, each using two of that processor type.

The DSP Configurator program calculates the processor usage of all active processors in the line output (D and F) and mic input (E) processor chains and the six most processor-intensive input processors (A), depending on the configuration. The program displays a DSP usage meter that

shows the results of this usage calculation.

The following table shows the DSP usage for each processor

type, the maximum number of processors that can be active within a configuration or current state/emulation, and the potential DSP usage if all of those processors are active at the same time.

NDSP usage percentages do not exactly add up to the totals due to rounding to the nearest 0.1%.

The DSP can overload when a combination of processors is enabled that totals over 100% usage. In this case, the switcher can lock up and fail to operate, necessitating cycling power. As part of its monitoring of DSP usage, when the DSP Configurator program detects that usage is nearing the 100% threshold, it makes uninserted processor blocks unavailable for insertion. This prevents an overload caused by normal operation. However, you can recall a combination of partial presets that causes an overload. The design rule verification function (see the next page), when used properly, can avoid an overload.
