Frequently Asked Questions
It's designed for clean amplification; however, pushing the gain too high will result in clipping, like any amplifier.
It can be, especially with sensitive oscillators; careful grounding and DC blocking might be needed to eliminate hum.
This is a dedicated amplifier, not a full mixer; it lacks EQ, panning, or multiple inputs, focusing on simple gain control.
