crystal - Sum Bus Parameters

The number of available sum buses, and whether 5.1 and DSP are supported, is determined by the Power Core license. Note that a stereo bus uses 2 resources and a 5.1 bus uses 6 resources.

By default, all sum buses come with DSP disabled. The individual DSP blocks are enabled by editing the system configuration using the ON-AIR Designer (under "Sum Bus → Parm"). 

Depending on the license, up to 32 DSP blocks (EQ, Dyn, Lim) and Delay are supported.

Signal Flow

The signal flow is identical to that of a source, except there is no input section or external insert point.

For each sum bus, the signal processing blocks are:

• EQ: 3-band parametric EQ plus 2-band filters.
• Dynamics: Compressor, Expander and Gate.
• Limiter: independent Limiter.
• Delay: up to 5.3 seconds, adjustable in ms, meters or frames.

Operation

The operation and parameters are identical to those of a source.
