What It Is

The LORDWORLD NS-03G is a compact digital amplifier built to drive a passive subwoofer with up to 100W of power. It uses a TPA3116D2 chip and a simple volume knob for straightforward bass reinforcement in a desktop or home-theater setup.

The Deciding Spec

This unit only works with passive subwoofers and will not function with active or powered subwoofers or regular speakers. A 3.5mm AUX input accepts line-level signals from phones, CD players, TVs and similar sources.

Build Integration

The amplifier requires an external DC power supply rated 12–24V at a minimum of 4A; one is not included. Its small metal chassis fits easily on a desk or atop the subwoofer cabinet, leaving the rest of your audio chain unchanged.

Questions about this item

What does the 100 W rating mean when I connect a passive subwoofer?

The TPA3116D2 chip delivers up to 100 W into a passive subwoofer; actual output depends on the supply voltage and the subwoofer's impedance.

What does the 3.5 mm AUX input actually accept?

The 3.5 mm AUX input takes a line-level analogue signal from phones, CD players, TVs or similar sources.

What do I need to mount or power the NS-03G?

The unit has no included power supply; you must provide a 12–24 V DC source rated at least 4 A, and its compact case sits on a desktop or atop the subwoofer.
