6. Signal Flow and Lake® Processing
6.1. Signal Flow
The gures below depict the audio signal ow 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 10.3.
