Works great . I wish I whould have hot the pro. But this one works flawless. Nice base. And great nearfield. Thanks fosi.

Great amplifier but it destroys my short wave listening

Prior to purchasing, I conducted extensive research into which amp would work best for my application which was for final connection to my old Bose Acoustimass 15 II Home Ent System. (Please note that I am only using two of the six satellite speakers as required for stereo sound rather than surround sound). Now having set up and used my new Fosi amp, I am very impressed with it. Easy Bluetooth connection and good control of the sound. The only negative point would be how close together the control knobs are which makes turning them slightly tricky. However, the compact size of the Fosi Audio BT30D is excellent as it doesn't take up much space so I guess this over-rides the slight disadvantage of the closeness of the knobs. All in all, this is a great little amp. Highly recommended.

I grabbed the non-Pro BT30D as my very first Fosi component, to build my wife a lovely 2.1 system for her new tiny Nucbox PC. I matched it with some classic (and old!) British speakers, namely a set of Gale Mini Monitors. I matched those with a (very cheap!) Pioneer passive subwoofer - and I must say that this combination of speakers and amp literally blew my mind.

Listening to some of my favourite tracks to dial in the subwoofer correctly saw me cry four times in the first hour, as the music moved me to tears. This hasn't happened since I was auditioning $100,000 of NAIM equipment in the 1990s! And so, Fosi are doing it all correctly: The sound - the form factor - the look - the individual components - it all adds up to be deeply synergistic, and you will be so incredibly impressed with the BT30D junior, that you will almost certainly rush out and buy a BT30D Pro with the bigger 48-volt power supply.

You will never be disappointed by the little BT30D (non-Pro) and it will make you smile a LOT.

10/10 - Unbelievable value, and stunning performance, in a tiny package.

Po meni je ovo jedno od boljih Fosi pojacala...

Using it as a 2.1 for the TV it's much better than the soundbar it replaced. The adjustable bass crossover and separate volume control dials it in perfectly to match the main channels. Bluetooth is flawless and the better speakers that are used the better it will sound surprisingly well worth every penny!

Good audio and excellent sound

This amplifier is solid. Sounds great and looks great. I have it hooked up to left and right channels, a passive sub, and an active sub. Using the 32 volt power supply that came with it and it is strong and loud. I'm glad I bought it. Thanks for a great product Fosi.

Thank you Fosi Audio. The BT30D bluetooth amplifier is one of the best purchases I made in a long while. I moved to a smaller apartment and needed a much smaller amplifier to drive my shelf speakers but did not want to lose any quality in sound. Wow the BT30D packs a quality punch. Wife is happy I am not taking up much space with my HiFi system, and I am happy with the quality sound! Win, win situation. Also I am glad I bought direct from Fosi Audio as I paid much cheaper and was kept up to date with the transit route of my package. It was a peace of mind purchase and will recommend anyone to do so. Well done Fosi Audio! Another very happy customer!

Great sound

Well done guys sturdy and powerful only thing I would add some frequencies on the panel for the sub freq selector I know it’s small but would help

There is a lot to like about this powerhouse amp. Actually everything, with the exception of an unsatisfactory explanation of how the frequency knob functions, namely, there are no units of measurement marked around the knob (example: 30 Hz, 50 Hz, 70 Hz) to know where the crossover is being set. Over all great amp.

I'm very pleased. Works perfect

Love the sound, but not enough power!

The mini amplifier works perfectly for my purposes.

Love that I can replace my big old receiver for this little Bluetooth gem. Love it!!!

Not only are your amps the real deal in terms of power delivery, but the small size allows me to tuck them away just about anywhere and my life has changed now because this has taught me the value of bluetooth!

Forget wires, just hang a TV on the wall and bluetooth the audio into these superb amps. Best of all there is no delay in the audio meaning there are zero lip sync issues. I wish I could say that about my MUCH more expensive Denon receivers, argh!!

And finally, maybe it's my imagination, I now own four of these and they always seem to arrive ahead of the expected delivery date. Please... don't spend more money than you have to, these absolutely rock!!!

Fosi Audio BT30D Bluetooth 5.0 2.1 Channel Power Amplifier with Bass & Treble Control

This amp gives a lot of value for money.
it is great for my home office where I listen to some background music from time to time.
It is basic. For this price I'm satisficed. Additional functionality could be nice like:
1. auto sleep.
2. auto recognition of S/W and there's not any - ignore crossover frequency automatically (I did it manually).

All in all, the pricing is in the sweet spot for me. Any cent over 75$ requires tax and handling cost in my country. So, yeah, works for me :)

Bought the amp for desktop speakers and passive sub. Worked ok, but caused ripples on the monitor. Tried moving the amp far and wide, different cables and even unplugged everything with no help. Distorted the monitor when powered on, no distortion when off.
Returned for no-hassle refund.

Very good and tiny!!! I used this for my TV and it is way louder than my soundbar!!! I have a matrix surrounded setup that sounds great for little money!!!

I'm blown away!!! This amp sounds good and it's small enough to hide behind a TV.
