Questions about this item

Should I pick the 300 W peak or the 40 W rated version?

The amplifier delivers 300 W peak per channel and 40 W rated per channel; choose based on whether your passive speakers need short-term headroom or continuous power.

What does 300 W peak mean when I connect 4-16 inch speakers?

Each channel can briefly output 300 W peaks while sustaining 40 W continuously, giving headroom for dynamic music or karaoke without overdriving the speakers.

How far does Bluetooth 5.0 reach in a real room?

Bluetooth 5.0 works up to 32 ft (10 m) line-of-sight; with a TV or PC keep the source within 15 ft (5 m) for a stable link.
