### What's New

#### Function Groups & Function Group EQs

A new organizational layer for managing your beams:

* Group beams by function: **Main Beams**, **Fill Beams**, or **LFE Beams**
* Apply a dedicated **6-band EQ** to each Function Group for streamlined tonal control across related beams
* Simplify complex system tuning by adjusting entire groups at once

#### Downmix Delay Matrix

Create sophisticated audio routing with the new Downmix Delay Matrix:

* Combine multiple audio sources into a single beam
* Set **individual delay** and **gain parameters** for each source in the mix
* Design complex downmix configurations with precise timing control

#### Signal Flow Visualization

A new way to understand your system in HOLOPLOT CONTROL:

* Visualize the complete audio path from **Audio Inputs** to **Beams** to **Modules**
* Trace signal routing through your entire system at a glance
* Quickly identify and troubleshoot routing configurations

#### HOLOPLOT Processor & AudioBridge Support

Two new products are now fully integrated into the HOLOPLOT ecosystem:

* **HOLOPLOT Processor**: Manage, monitor, and configure processors directly from HOLOPLOT CONTROL
* **AudioBridge**: Full support for AudioBridge devices with health monitoring and status display
* View processor status at a glance in the CONTROL footer
* Automatic failover event notifications for processors

#### Amplifier Protection

* New rail protection feature helps safeguard your amplifiers
* Monitor protection status through HOLOPLOT CONTROL
