This guide explains how to connect a physical on/off switch to a Solaro DSP and use it to mute or unmute your audio system.

Connect your on/off switch to a GPIO Input pin and GND on the GPIO Card.

(Any simple latching or momentary switch can be used depending on your logic setup.)

In your project, add the following modules:

• Logic Controlled Mute

Then:

1. Wire the GPIO Card to the GPIO Input.

2. Wire the GPIO Input to the Logic Controlled Mute.

3. Route all audio through the Logic Controlled Mute before it enters the mixer or output stage.

   

Flip the hardware switch:

• ON = mute active

• OFF = normal audio restored

Verify that all intended audio paths mute and unmute correctly.
