The High-pass Filter (HPF) is an essential tool in audio signal processing, used to remove unwanted low frequencies to help the loudspeaker system perform more clearly and stably. In Lake Controller, users can configure either the Input HPF or Low Output HPF depending on the system setup and signal processing requirements.

During the operation of an audio system managed by Lake Controller, you may occasionally need to replace a Frame due to hardware failure, maintenance, or simply to swap it with another device. Instead of reconfiguring everything from scratch, Lake Controller allows you to copy and replace Frames quickly using the Batch Replace and Frame Copy/Replace functions - preserving all I/O settings, labels, and module presets.

Updating the firmware ensures your Lake system operates stably, remains compatible with the latest software, and performs at its best. The following guide explains in detail how to update the firmware for your Lake Frame or PLM+ / D Series device using the Lake Controller software.

In certain cases, your Lake Controller or Lake Frame device may boot into Safe Mode after a failed firmware update. Don’t worry - the following procedure will guide you through safely restoring the device and correctly reinstalling the firmware.
