BT30D PRO

I am quite picky and want a clean, high-quality sound with plenty of volume when it comes to hifi. This is a very compact little amp (40mm high, 120mm wide and 160mm deep). It has a good quality feel and a reasonable weight to it. I am using it to drive 2 Q Acoustic Speakers (2020i) that are rated 75 watts at 6 Ohms. I have the amp connected via banana plugs. I would say the amp matches these really well and drives the speakers fully. Not too much and not too little. At max volume there is a touch of distortion but not that much and honestly whilst I do like loud music, I would not really want my music that loud in the kitchen, I have another set up for that elsewhere. The treble and base adjustment may in some ways seem old fashioned but I really like them as you can give it a little more base or treble depending on your speakers, the music and of course your personal preference. You can get graphic equalisers to add to your phone, etc, but the on-amp adjustment just seems more accessible. I am not using the bass driver and honestly I do not think I will. So why did I buy this amp when Fosi do a version with no bass driver? Well, Amazon had a discount that made this version only £5 more than the non-bass driver version. Another reason though was that this comes with a 32 volt power supply and the non-bass driver version ships with the 24 volt supply but can be upgraded to the 48 volt supply. This means you will not get full performance if you only buy the one that ships with 24 volt supply. You can upgrade on the Fosi website but not on the Amazon website. You can buy the 48volt power supply separately on Amazon but this pushes the price up quite a bit. So, therefore I preferred this slightly higher spec model that ships with the 32 volt supply from Amazon and this is the max supply allowed for this unit, I think. That was my logic and it would be interesting to know what Fosi themselves think about this and whether my deductions were correct. I think Fosi should add the 48 volt power supply option to the non-bass driver unit on Amazon. I use this in my kitchen and for me a key selling point is the size. I have built it in to the bottom of one of my kitchen cupboards and of course its small size means it is very discrete. The Bluetooth works fine. Still good volume. It connects easily and makes a little bleep to signal connection. You can also connect directly if you have the right cables. The sound quality and volume are marginally higher and cleaner when connected directly, but the Bluetooth still sounds good. My arrangement slightly compromises the view to the Bluetooth antenna, which I have rotated so it is exposed somewhat. This does not seem to make much difference and the range is still fine. I am using it with iPads, iPhones and Samsung phones. All work fine. So I am very happy with this Fosi unit but I would recommend you look at their full range, perhaps on their website before you decide the best one for you. I went for Amazon because I knew it would come quickly and be an easy return if I did not like it. I am a bit shocked and pleasantly surprised that such a tiny and affordable little unit can be so good. Well done Fosi. (Ultimately I decided to get the non-bass model with the 48 volt power supply. This does give slightly greater volume with less distortion which is why I have updated this review.)

It’s so small, it’s so cute, it’s so SOLID. It’s a micro beast! My Use case scenario is my old Sony micro hifi was being used for my computer sound output. I decided to put the old Sony into the garage for some tunes in there which left me with only headphones on the computer. I got my brain into thinking I would like a retro speaker set like my dad’s old bang and Olufsen cx100’s back in the day. I found some on the big auction site that were well looked after and serviced. I also found a non amplified subwoofer that fits into my ikea kallax unit but needs an amp. I found reviews saying this fosi amp could run both my cx100s AND the sub. ITS AMAZING ! It runs them all and runs them as loud as I could dare go and then some! So easy to use, and the Bluetooth is so clear with little to no delay if you use it, though I’m happy with the red and white line in from the wired headphone output on the Mac. The Bluetooth from the laptop is just the icing on the cake for me. I found a copper volume knob for sale on the fosi website as it seems the latest pro amps have it included in the box.. mine didn’t. Small caveat… you cannot turn off Bluetooth. It’s always on and ready to pair if there’s nothing currently connected. If you have neighbours with a bad sense of humour.. you might be woken with the birdy song or Agadoo by black lace at 2 am. It’s not as funny as it sounds. I unscrewed my Bluetooth antenna. Still gives a 5m perfect signal but is just too far for the funny man next door to reach it now.

Bought this to pair with a cheap turntable to play through the speakers of an old home entertainment centre that died a few years ago. The speakers were 2 ohm which limited my choices a bit, but I thought I'd take a punt on this little amp. So far, it's been great. Connecting it up was easy, standard phono plugs to the turntable and banana plugs to the speakers. The banana plugs weren't actually necessary as the port caps are screwable, so you can just attach the speaker cables and screw them down - but as I knew I was going to moving the whole system around until I was happy with it, I fitted the banana plugs to make it less of a hassle. The amp also has Bluetooth in, so you can play music from your phone too. I've got this set up as a 2.1 system, with a passive subwoofer and the amp drives that fine. The ONLY way this could be improved for me would be for them to add a balance control to even out my (by necessity) dodgy speaker placement. It all sounds great and for the price, I don't think you can go far wrong with this, so would recommend.

I decided to give this little BT30D Pro unit a shot to see if I could breath some life into an old pair of Gale Model 4 Floor stands. I was blown away by the sound quality. They're rated at 6 Ohm, 10-120 Watts with a freq response of 38Hz-22kHz so they matched the BT30D Pro perfectly. They sounded better than I ever thought they could. I enjoyed the great range of sounds from punchy bass, warm mids and clean crisp highs. I had to adjust the volume to half way for bluetooth and back to 9-10 O'clock for my Pioneer CD player. Both sources sounded amazing, but I felt the CD player had the edge. To my ears there is a sweet spot with the volume where the separation was at its best, below that the sound felt flat. Unfortunately, there was a fault with the power switch when it arrived. I had to flick it on/off 3 times every time before it would power up. I contacted Amazon support and they were amazing and arranged a refund. I was reluctant to return it but I couldn't take the chance it might pack in completely. Despite the hassle, I decided to give Fosi a second chance, and I ordered the BT20A Pro because I don't plan on adding a passive sub. If I do add a sub, it'll be an active sub and this unit, just like the 30D, has a pre-out. Fingers crossed I'll have better luck with that one. The QA issue that should have been caught in the factory, and the volume sweet spot is why I'm docking a star.

Well pleased with this little amp and glad I went for the pro version as you can adjust the sub frequency and volume when using a passive sub, I also added the passive Roxel Bookshelf speakers and everything is handled without an issue, I was tempted to use the pre-out as well with a pair of powered speakers although there is absolutely no need the sound is amazing you can hear everything, in amazing clarity, and of course the option is always there if I feel like adding to the system at a later date. I connected via the amp to my iPhone via Bluetooth and the connection was instant. So impressed with this amp and I can now watch TV via a DAC, I would advise getting one with a remote as I cannot deal with adverts and this allows me to mute the amp as there is no remote with the amp, because all the money has gone into the internal components, all good with me. Highly recommended.

Outstanding amp good separation plenty bass and treble control and volume on my Wharfedale diamond 5 Speakers in the large kitchen Fills the room Recommended

It works, it's powerful enough, it's good value for money in that sense. However there are some significant compromises - there is no balance control and you can't turn bluetooth off. I don't want to use bluetooth, I don't want anyone else connecting to it either so I've removed the antenna and am hoping that's enough. My speakers also had to be repositioned because I was relying on a balance control on my last amp to account for one being slightly further away.

I’ll start by saying that if you just need an amp with bluetooth - don’t bother with this one and get the Fosi BT20A Pro - that model can be run with a 48v power supply which ups the wattage and will be more than enough for most people. This BT30D Pro however is perfect for me because I can easily play around with subwoofers to compliment the main speakers I use. You can easily pick up faulty high end subs on eBay/Facebook and simply bypass the broken amp sections and go straight from the Fosi. I also have one of these amps in my van being powered from an inverter. Two small tannoy satellites on the dash and a chunky 12” jbl sub in between the front seats which also acts as a table. I leave the volume up full whack, turn the bass almost right down on the satellites and tune the bass via the sub… all being bluetoothed from my phone. It can get some serious volume and quality at the same time. It’s great value for money and I don’t see how you could spend your money any better.

Amazing Amp for a small stereo setup in our living area. It sounds great driving a pair of Q Acoustics 3090i bookshelf speakers and a small powered Focal sub. It's compact and unobtrusive. I thought I'd use the RCA jacks as a source with a ipod or old phone, but it's mostly driven via Bluetooth from an Amazon Echo. The Bluetooth connection is quick and stable with no drop-outs. One minor omission is a lack of a Toslink/optical input, but honestly that's a very minor thing, and Fosi do other units that have that if it's important to you. Would definitely recommend.

Sorprendente sotto ogni aspetto. Nonostante le dimensioni compatte, questo mini amplificatore eroga un suono pulito, potente e ben bilanciato, perfetto per gestire sia diffusori da libreria sia un subwoofer dedicato. Rapporto qualità/prezzo semplicemente imbattibile per chi cerca un impianto Hi-Fi da scrivania o per piccoli/medi ambienti. Promosso a pieni voti!

I was not expecting much when I ordered the Fosi Audio BT30D Pro, after all what could you expect for CAD $140.00? I purchased this as a Hail Mary pass to try to raise my Paradigm Millenia CT, Shift Series 2.1 computer speaker setup from the dead after it had given up the ghost due to a failed amp board. Paradigm customer service was unacceptable -“We no longer produce that amp board. Our best advice is for you to purchase a more current model from our product line”. I may be old school, but I expect speakers costing $750 to last a lifetime. ( I still have a Pioneer SX- 767 seventies era receiver that works perfectly) After some research, I decided that a solution might be to bypass the Paradigm expression of crap and use a separate Class D amp to drive the satellite speakers and sub. The result: in short, I was blown away by the sound quality that this Fosi amp delivered. The resultant sound far exceeded the original Paradigm amp board. More articulate highs, better sub performance and a wider, deeper soundstage than the Paradigm amp. In all fairness, the power output of the Fosi amp is more than triple that of the original Paradigm amp, but the improvement in sound quality makes me question whether Paradigm’s product was under powered, given the obvious capabilities of the speakers and sub powered by this Fosi amp. I highly recommend this amp. At this price I do not think you can go wrong. Note: I use this with my computer speakers to listen to digital music files, mostly in FLAC format, via a wired connection to my music server. If you use it to play MP3 or compressed, Apple format files over a Bluetooth input, your mileage may vary, and as noted in some of the reviews, gamers may not be satisfied with the sub output. So, in conclusion, the Fosi BT30D pro exceeded my expectations and I recommend it as excellent value for the money. Paradigm equipment – less so.

Öncelikle eksik yönlerinden bahsedeyim. Ses ayarları ortada olduğunda mekanik bir his vardır. Bakmadan ayarlayabilmeniz için, işte bu cihazda o yok. Bluetooth bağlantısını kapayamıyorsunuz ve şifreleme yok. Şakacı komşularınız varsa tek çözüm anteni çıkarmak. Kapatmak için bir switch olsa iyi olurdu. Analog ses girişi katı bluetooth'dan çok daha iyi ses çıkışına sahip. Balans Ayarı yok. Şimdi artılarına geçelim. Ses yüksekliği fazlasıyla yeterli, 2 adet pasif subwoofer besleyebiliyor. Bas ve siz sesleri de distorsiyonsuz veriyor. Bilgisayar ile kullanmak için ideal. Az yer kaplıyor çok ses veriyor. Daha da yüksek ses vermesini isterseniz daha yüksek amperli güç kaynağı kullanmanız lazım. Sesini sonuna kadar açsanız bile statik elektrik sesi duyulmuyor, uğultu yok hafif bir tıs sesi var yani yalıtımı iyi başarmışlar. Bas açtığınızda Subwoofer'lara giden ses değişmiyor. Subwoofer gain ve frekans ayarı düzgün çalışıyor. Pasif subwoofer kullanımı için çok ideal. Ayrı pre out ile başka amfilere veya cihazlara bağlayabilirsiniz.

I bought the Fosi Audio BT30D Pro to power my barn sound system, running two Alpine 6.5" coaxial speakers along with a 12" JL Audio W0 subwoofer, and this amp completely exceeded my expectations. For the size and price, the performance is unbelievable. The sound quality is excellent — clean highs, strong mids, and surprisingly powerful bass output. It had no problem driving my speakers and subwoofer to levels that easily fill my entire barn while still sounding clear and controlled. The subwoofer controls are especially nice because they let you dial in the bass exactly how you want it. The Bluetooth performance has been flawless. Connection is fast and stable every time, with no annoying dropouts or pairing issues. I can walk around the barn with my phone and the audio stays connected perfectly. It honestly works better than many much more expensive receivers and amps I’ve owned. What impressed me most is how much power and sound quality Fosi packed into such a compact amp. It runs cool, feels well-built, and has been completely reliable in my setup. After using it, I genuinely feel this is one of the best values in audio equipment right now. If you want an affordable 2.1 amp with excellent sound quality, real output power, and rock-solid Bluetooth performance, the BT30D Pro is an easy recommendation. I turned my friend onto them and he wound up buying a second one because he liked it so much!
