If the required audio signal is not passing correctly,

verify the connection, mute and gain settings at all

seven stages.

5.1.1

Power Output Section: Limiting and Sensitivity

The Current Peak Limiter (CPL) dynamically limits the drive to the power stage based on three parameters:

sensed output current level, feedback from the output stage, and sensed voltage clip from the ISVPL. This

ensures that power output is maintained within the design limits of the PLM.

The adjustable Inter-Sample Voltage Peak Limiter (ISVPL) sets the PLM's maximum output voltage and

therefore also the maximum output power. The ISVPL setting is made via MENU > MODULE > LIMITERS

> ISVPL, and can also be set from the Lake Controller software.
