Questions about this item

How long can the built-in speaker run at high volume before the 30-day warranty becomes the limiting factor?

The 30-day warranty covers defects, not usage time; the speaker is designed for continuous operation during normal karaoke sessions.

Does the unit produce noticeable fan noise or heat when running all day?

No fan is mentioned; the system uses passive cooling, so heat and noise stay low during extended use.

What external devices must I already own to use the Bluetooth streaming and the Singing Machine Mobile app?

You need a Bluetooth-compatible phone, tablet or computer running iOS, Android or Windows, plus an iOS device for the dedicated app.
