I bought the full Freq version and a 24v 6amp power supply, have stereo Bluetooth as an input which is summed to a mono output by the amp. Output (banana plugs required) goes to two outdoor Yamaha wall mounted speakers wired in parallel (halves the speakers ohms) to give mono music (ideal for outside) all around the patio. Very powerful, very little, very impressed. Would buy a second one for another project in a heartbeat. Review: This is a reasonably competent module and importantly.. ... - This is a reasonably competent module and importantly... it works. It should be pointed out that you need a DC power supply. Nobsound do one which is inexpensive or you may consider using a Buck inverter with either a battery pack or a DC power supply in excess of what the Nobsound module uses. In my situation I made a portable Om-nidirectional speaker with down firing subwoofer which this module powers well. ## Features - Adopting classical TPA3116 amp IC, class D amplification, max output power can reach 100W(4Ξ© load), easily to drive all home bookshelf/ computer/ desktop/outdoor passive full-frequency speakers and match perfectly with them. - With 3.5mm AUX audio input, perfectly compatible with many audio devices such as phone,TV, MP3, CD players, computers, DAC etc.. With built-in preamplification circuit, can match well with the audio sources that with low signal output. - Reasonable circuit, concise wiring layout and perfect protection, no sparks no shock. Adopting NE5532 op amp with ultra-low distortion, the sound is very smooth and natural, powerful in low frequency and delicate in high frequency, full of music styles. - Mini size with exquisite appearance, aluminum alloy black case looks fashionable and attractive. With strong output power and high-quality sound, especially designed for the customers who pursue HiFi sound. - Warm tips: 1. This is Nov. 2022 latest updated version, simplify the circuit, upgrade the components and greatly improve the sound quality; 2.

It should be pointed out that you need a DC power supply. Nobsound do one which is inexpensive or you may consider using a Buck inverter with either a battery pack or a DC power supply in excess of what the Nobsound module uses. In my situation I made a portable Om-nidirectional speaker with down firing subwoofer which this module powers well. ### ⭐⭐⭐⭐⭐ Amazing small device *by P***O on 23 October 2021* Amazing and powerful small device, exactly what I was needing for my setup. The NS-03G-FR takes the 3.5mm aux input stereo signal and combines/sums both sides into a mono RCA output. Perfect if you want to use just 1 single full range speaker. Quite difficult to find a power supply with the right connector that fits, this way, I would recommend to purchase the power supply together. ## Frequently Bought Together - Nobsound 100W Full Frequency Mono Channel Digital Power Amplifier Audio Mini Amp (Full Frequency, Black) - Nobsound DC 24V/6A 150W Power Supply Adapter, AC 100~240V Power Brick for Amplifier --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/56237135-nobsound-100w-full-frequency-mono-channel-digital-power-amplifier-audio](https://www.desertcart.in/products/56237135-nobsound-100w-full-frequency-mono-channel-digital-power-amplifier-audio) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-11-03*
