Frequently Asked Questions

The rear contact inputs allow for triggering presets via external switches or control systems, requiring a physical connection for each preset.
While Class D is generally clean, very aggressive clipping can introduce a subtle harshness; proper gain staging is essential to avoid this.
You should expect a reasonable amount of headroom at 4 ohms, but prolonged operation at maximum volume could lead to thermal protection triggering. Careful monitoring is advised.
