6. Signal Flow and Lake® Processing
6.1. Signal Flow
The figures below depict the audio signal flow for a PLM+ Series device. It is worth noting that this sophisticated
device provides seven points in the signal chain where the signal level can be adjusted, muted or disconnected.
The blue sections represent Frame data, and the red sections represent Module data - please refer to the Lake
Controller Operation Manual for further information.
Important information regarding correct setting of the gain structure can be found in section 10.2.

1
The input section (inputs, input router and input mixer) allows for mixing capabilities as well as redundant and
prioritized inputs with automatic switch-over in case of signal failure.
2
Up to four Lake Processing modules provide user EQ and loudspeaker processing, including LimiterMax limiting.
3
The Output router allows free routing between module outputs and power output channels.
4
Each power output channel provides individual channel processing, including ISVPL limiter, RPM and
load monitoring.
