Mono amplifier for one passive speaker

The LORDWORLD NS-03G is a mono channel digital power amplifier built to drive a single passive speaker. It uses a TPA3116D2 chip rated for 100W output. A 3.5 mm AUX input accepts sources such as phones, CD players or televisions. The unit requires an external 12 to 24 V power supply capable of at least 4 A, which is not included.

Sustained output with external power

Because the amplifier draws its energy from an external supply, continuous performance depends on that supply maintaining 12 to 24 V at 4 A or more. The TPA3116D2 chip delivers its rated 100 W as long as the voltage rail remains stable and thermal limits are not exceeded. A smooth volume knob allows fine level adjustment during extended listening sessions. The compact metal chassis aids heat dissipation in desktop or shelf placement.

No power supply included

This product ships without any power adapter, so buyers who need a complete ready-to-play solution must source a suitable 12 to 24 V, 4 A unit separately. It cannot be used with active or powered speakers, only with a single passive speaker. The 3.5 mm AUX connection is the sole audio input provided.

Questions about this item

Does the TPA3116D2 chip run hot when the NS-03G is driven at 100 W for long sessions?

The Class-D TPA3116D2 chip is efficient, so the solid shell stays warm rather than hot during extended full-power use.

What power supply must I already own to run the NS-03G?

You need a 12–24 V DC supply rated at least 4 A; the unit ships without one.

Can I keep my old passive bookshelf speaker and just add the NS-03G?

Yes — the amplifier is designed for a single passive speaker and connects via 3.5 mm AUX from your source.
