Compact mono amplifier bundle

The LORDWORLD NS-03G bundle pairs a mono digital amplifier with a matching 19V 4.74A power supply. It is built for listeners who want to drive a single passive speaker from a line-level source. The TPA3116D2 chip provides 100W output for desktop or living-room use. The metal chassis keeps the footprint small.

Simple setup with one input

Connection is made through a single 3.5mm AUX jack, so any phone, TV, CD player or computer can be plugged in directly. A smooth volume knob on the front panel gives immediate level control. The included 90W adapter is certified to UL, FCC, CE and ROHS standards and mates with the amplifier's DC barrel jack. No software or pairing steps are required.

Limited to one speaker and wired sources

The mono topology means only one passive speaker can be powered; a second speaker would need another amplifier. The 3.5mm input accepts analogue signals only, so wireless streaming or digital optical sources cannot be connected directly. Maximum output is 100W into a suitable load, and the 19V 4.74A supply sets the available continuous power.
