Frequently Asked Questions
The audio limiter protects against clipping, preventing distortion and speaker damage – it's a fixed threshold, not user-adjustable, prioritizing safety.
The Speaker Twist outputs are standard twist-and-lock connectors, common in professional audio applications, offering secure speaker connections.
While convection is primary, a small fan assists cooling; expect moderate fan noise under heavy, sustained loads – it's not silent operation.
