Channel Groups

What Are Channel Groups?

Channel groups let you organize your amplifier's output channels into logical volume zones. For example, you might group your front speakers into one zone and your subwoofer into another, so each can be controlled independently from the knob.

For a full explanation of channel groups, relative mapping, and deployment examples, see Channel Groups and Multi-Unit Control.

Opening Channel Groups

1. Connect to your WVC in the AuralSync app.
2. Tap the gear icon to open device settings.
3. Scroll to the Channel Groups tab.

Setting the Number of Groups

At the top of the screen, set how many channel groups you want. You can have as many groups as you have channels (up to 24 across linked units). When you change the group count, the channel assignment section updates automatically.

Naming Groups

Each group can be given a custom name up to 10 characters — for example, "Front", "Sub", "Rear", or "Fill".

1. Tap a group name field.
2. Type your desired name.
3. The name syncs automatically to all connected devices when you save — it will appear on the knob display, the RTC screen, and in the app.

Groups without a custom name display as "Group 1", "Group 2", etc.

Assigning Channels to Groups

Below the group names, each physical amplifier channel is listed with its current group assignment. To reassign a channel:

1. Find the channel in the list (organized by unit if you have multiple WVC units linked).
2. Change its group assignment using the dropdown.

Adjusting Per-Channel Gain

Each channel has an adjustable gain from 0 dB to +31.5 dB in 0.5 dB steps. This lets you boost the output level of individual channels within a group — useful for balancing channels that receive different input voltages, or for driving amplifiers that need a stronger signal.

How Gain Affects Output Voltage

The gain setting controls how much the WVC amplifies the signal passing through each channel. At 0 dB, the output matches the input (unity gain). Each step adds 0.5 dB of boost.

Formula: Output voltage = Input voltage × 10^(gain in dB ÷ 20)

Relative Mapping

Each group can be set to one of two modes:

• Standalone — volume is fully independent of all other groups
• Relative to [Group] — volume moves proportionally to a parent group

For example, if your subwoofer group is set to "Relative to Front," turning down the front volume automatically reduces the subwoofer volume proportionally.

Saving Changes

When you're done editing:

• Save — sends the configuration to the base station, which distributes it to all connected devices (knobs, RTC units, and mesh peers). Unused groups are automatically removed.
• Discard — reverts all changes without sending anything to the device.
