Small footprint, simple control and enough power for compact audio or tactile builds.
The Nobsound NS-01G Pro is a compact stereo amplifier built around the Texas Instruments TPA3116D2 Class D chip. It is a clean, affordable choice for passive speakers, desktop audio and entry-level sim racing tactile feedback where you want a simple RCA-in, speaker-out amplifier without a bulky hi-fi receiver.



Useful for small speakers or light tactile feedback systems.
The NS-01G Pro is ideal when you need a small amplifier close to the rig, desk or equipment rack. It can drive passive speakers for a compact audio setup, or power smaller tactile transducers when you are building an entry-level bass shaker system for sim racing. For large bass shakers or a serious multi-transducer tactile rig, choose a stronger amplifier instead.
Easy to place on a desk, shelf, side profile or inside a small cockpit accessory area.
Direct hardware control without digging through software every time you want to tune output level.
Simple connection from compatible audio interfaces, PCs, DACs or line-level sources.
Connect passive speakers or suitable small tactile transducers with standard speaker wire.
This is not the right amplifier for high-power bass shaker builds with large transducers.

Power without the heat and size of a traditional amplifier.
Class D amplification keeps the unit efficient during longer use, so it stays practical for all-day listening, long sim racing sessions and compact installations where space and heat matter. Built-in protection helps keep operation reliable when the amplifier is used within its intended limits.
Efficient Texas Instruments Class D amplifier platform.
Large physical knob for quick level adjustment.
Supplied with a 12V/5A adapter for a ready-to-use compact setup.
Designed for stable use when paired with suitable speakers or transducers.
Everything needed to start with a compact stereo amplifier.
The package includes the amplifier, a 12V/5A power adapter and a user manual. Speaker cables, RCA cables, speakers and tactile transducers are not included, so you can choose the correct wiring and output hardware for your setup.

Nobsound NS-01G Pro compact stereo amplifier.
12V/5A power supply included in the package.
Basic setup and operation information.
Simple two-channel amplification for small audio and sim racing projects.
Can it drive tactile transducers?
Yes, but only for light or entry-level tactile setups with suitable small transducers. For larger bass shakers or a stronger sim rig haptic system, this amplifier is undersized and a higher-power amp is the better choice.
Does output depend on the power supply?
Yes. The 2x50W rating is load and power-supply dependent. The included 12V/5A adapter is suitable for compact use, while maximum output figures require the correct load and supply conditions.
