Can this amplifier power my 8Ω bookshelf speakers?

Yes! The NS-13G MAX supports 4Ω-8Ω speakers with auto-adjusting output power (300W×2 at 4Ω). It delivers crisp, distortion-free sound even at high volumes.

Does the phono input work with all turntables?

It’s designed for MM (Moving Magnet) cartridges, compatible with most modern turntables. If your turntable uses a MC (Moving Coil) cartridge, you’ll need an external preamp.

Can I connect both a subwoofer and speakers at the same time?

Absolutely! Use the banana jacks for passive speakers and the 3.5mm AUX output for a subwoofer/active speakers. All outputs are synced to the main volume control.

Will it overheat during long movie sessions?

No. The CNC aluminum chassis and dual cooling vents ensure efficient heat dissipation. It’s tested to run safely for 12+ hours at 80% volume.

Is the power adapter included?

Yes, a 48V/5A power supply is included. Just plug in your devices and play – no extra purchases needed!
