Audio Level, Mix-point, Processing Blocks and Signal Chains
All blocks on the main DSP control screen have one of three main functions:
• Level control (gain/volume/trim)
•
Mix-point (signal routing)
•
Signal processing (filter/feedback/dynamic/delay/duck/loudness)
The signal chain varies depending on whether it is in the input, output or virtual bus stage.
The input chain begins with a level control (input gain), filter, feedback suppression, two
dynamics, and a delay processor, then ducking and a pre-mixer gain control. The output
chain begins with a level control (post-mixer trim), loudness, delay, filter, and dynamics
processing blocks, and an output volume control. Each virtual bus chain has a filter, a
dynamic processing block, loudness and output trim control. All mix-points have a gain
control.
Each of the three signal processing chains; Input ( a / b / c ), Output ( e / f / g ), and
Virtual ( h ) shown in figure 45 above, consist of a series of control blocks of two
basic types specific to that chain: level control (gain, trim, and volume control
blocks), and signal processors (frequency filters, feedback suppression, dynamics, delay,
ducking, and loudness). Both types of blocks are always present in the signal chains. Gain
controls default to unmuted and processor blocks are bypassed upon insertion.
Gain, trim and volume blocks can be muted and processor blocks (after being inserted)
can be bypassed for signal comparison. Mutes and bypasses are shown by a red indicator
in the lower left of the block.
