This bundle pairs a Nobsound NS-03G digital amplifier with a matching 19V 4.74A power supply. The TPA3116D2 chip drives passive subwoofers with up to 100W of power. A 3.5mm AUX input connects phones, CD players or TVs. The universal 100-240V adapter works worldwide.

Replaces Separate Amp And Power Brick Purchases

Buyers who previously sourced an amplifier and a compatible power supply individually gain a pre-matched set with certified safety protections. The jump is worth it when building a new desktop or home-theater subwoofer system and wanting guaranteed compatibility without researching voltage or current specs.

Sustained Output With Certified Protections

The included power adapter carries UL, FCC, CE and ROHS certifications and features overload, overheating and short-circuit safeguards. Pure copper wiring maintains stable current delivery during extended listening sessions. The mini chassis suits compact installations where airflow is limited.

Questions about this item

What power connector does the NS-03G amplifier need from the 19 V 4.74 A supply?

The bundled power adapter provides a DC barrel plug that matches the amplifier's 19 V input, so no separate cable is required.

How do I connect a source to the 3.5 mm AUX input on the NS-03G?

Plug a standard 3.5 mm stereo cable from your phone, TV or CD player into the AUX jack, then connect the passive subwoofer to the speaker terminals and power on.

When should I consider replacing the 19 V 4.74 A power adapter?

Replace the adapter if it shows physical damage, overheats, or the protection circuit trips repeatedly during normal use.
