great amp I picked one up 2 weeks ago for my computer I'm running the Klipsch r51m and a Klipsch 10 inch sub.highly recommended.
Awesome I'm glad that he liked these as much as I did.
@@marhotiewer yes they go loud as klipsch are efficient speakers you will have no problems with the set up.
@@marhotiewer as i have owned this set up for 2 months and very happy with it.
I ve had the amp 1 month not 2
@@hanzdidit yes hanz thank you.
Tks Sir. Speaker outputs 50 + 50 & sub woofer 100 watts. Right ?
Question from the new guy...which cables are you using? I'm building a budget budget 2 speaker and sub system.
I am using 14 gauge wires to connect to my speakers.
I would like to pair this amp with Klipsch R41M. May be with a passive subwoofer in the future. Would you recommend bt30d for the mentioned setup, Please advise...thanks
Yes this is the amp I am using now and I am super happy with it. I am using a passive sub and it works great, I did make a video about it.
Can an external equalizer be added to the Fosi BT30D? If so, how would that connect? Thank you
It would definitely be possible, but I am not sure how because I do not know which one you have. There are RCA jacks that you can connect outside components too and it should work fine.
I've got a Theater Solutions sub8s and a pair of klipsch cdt-5650-c-ll for a kitchen remodel. Would you recommend the bt30d for this application?
Yes I think you will be happy with this setup.
Do you hear a static noise close to the speaker. I hear it on mine but not sure what’s causing it
No I have tested that on all of these and I have not had any feedback issues. If you don't have your positive and negative hooked up correctly sometimes that can cause that. The only other thing I could think of is if you have the volume cranked up all the way to the max it might create a small Hess and speakers..
@@hanzdidit it’s wired correctly. I think maybe it’s my DAC. It’s a 20 dollar Amazon DAC. I have a new one on the way and maybe it’ll fix it
I got one .the volume level is terrible. I turn it up past 3/4 and it's still not loud at all .tried it with different speakers and sub .the volume was terrible. I turned it up all the way and it didn't get any louder then it did at 3/4 .I am bummed to say the least .every review for this amp was good so I bought it .I think people get paid to give good reviews
I feel like maybe you just got a bad amp, so far I have been super impressed with all of the ones I have tried. I have them working in my garage and in my shop and have had a great experience with them so far. Sorry you got a bad one but maybe you should try another amp. Sorry if you feel deceived by these do you actually work. Thanks for watching.
What power supply were you using?
Dude, what's the name of the track played around 4:52 minutes. It's nice!
I am not sure i got the music from Envato and i was just sourcing 808 beets, there was a bunch of good music i found. Sorry i do not remember the name. Thanks for watching.
Thanks for your videos. I'm new to audio. I'm considering the Fosi amp. But I don't know the name of the output plugs. My speakers accept post (like banana). Do I need banana plugs on the other end for the Fosi amp output? Do I need four? (two +- for left speakers, two +- for right) Thank you.
You can just strip the wires and use the connectors on the back of the amp.
@@hanzdidit Thanks Hanz. I got banana plugs and they work fine.
Very new to this. Was considering adding a MTX Audio TNE212DV with this Amp. Would you know if this sub would work? Also would you happen to know if this sub uses RCA cables?
This particular amp is meant to power a passive subwoofer, if you try to hook it up to a powered sub for subwoofer would not work very well.
@@hanzdidit Hello Hanz. Do you know if the main speaker outputs auto adjust high pass with adjustment of the low pass subwoofer control??? I'm assuming the main speaker out's ALWAYS play full range signal, regardless of the subwoofer freq setting? Thx
Why is the connection for the PRE OUT different than the RCA connection for the line in ?
It depends on which amp you're talking about but this one has a output for a preamp base if that's what you're asking me
Morning Hans. Thanks for ur insights on the BT30D, which I have ordered through Amazon.
My question is..Can this devise be hooked onto the ADCOM power amp to drive the Klipsch 100watts each Tower model speakers and the Definitive Technology Sub (250 watts) together and get a rich Audiophilic sound...just like the normal integrated or stereo amp?
I'm not much of a technological expert like most in here are, except that I love the old 80's & 90's music, apart from the country music that I listen a lot to.
Could u please advice on this question that I have requested. Thank you and wishing u every success in the vedios that you are doing. Do have a lovely day ahead.
To be honest with you I'm not 100% sure. These many amps are supposed to act as the amp so you should not need an extra amplifier on your speakers. Your subwoofer is a different story if you have a powered subwoofer and just need the signal to go to the powered subwoofer than you connect an RCA to the subwoofer and you should get great results. Hopefully that was helpful I'm not really sure if I answer your question or not.
@@hanzdidit First of all thank u for ur quick reply Hans.
Well, the speakers are not the book shelf kind, these are Tower models. The BT30d looks really puny in comparison to these large speakers and The Sub.
Hence, it's kind of looks Awkward to acknowledge that this small Amp may really do the job of powering the Klipsch speakers. Since I already have an ADCOM (Model GFA - 2535) I was thinking if I should connect the BT30d through the Power Amp to get a richer sound effect.
Is there built in crossover that filters out just the low bass so when you connect a subwoofer,automatically low frequency comes out of it?
Yes
Good presentasion I have 120w old Pioneer speacers what do you recomment it's for home use.
This is the one I use in my house, it sounds great!
@@hanzdidit Ok...70w x2 ...8ohm it should work....
Hanz,
Do you know if this amp will reliably drive the Jamo 801s and a Jamo 808 sub? I'm looking to upgrade my girlfriends' turntable setup from an old Sony reciever that has seen better days and can't find the answer I'm looking for. General audio recommendations like impedance and wattage matching between the amp and speakers don't help out too much since Fosi lists such a wide range in the manual.
I think this would work just fine. the powered 801 and 808 subs just use a signal from the amp it is not actually driving the sub so it should work great. thanks for watching.
@@hanzdidit thank you for the response. I realize the 808 sub is powered and is just getting the signal into its own amp. The 801 bookshelf speakers aren't powered and the listed power handling is 60W/120W. Will the 50W per channel from the BT30D be enough to drive them? I'm new to this and don't really understand the numbers.
Are the outputs jacks compatible with bare wire ends? My speakers only have bare wire ends on it.
Yes you should definitely be able to connect your bare wire ends to this amp. I think you'll like it so far I have had a lot of luck with these. Thanks for watching.
No, there are two different outputs for a subwoofer; one for powered subs, and one for passive subs.
Yes I say that in the video L and S and Sub Or RCA
Does 100W Yamaha speakers works with this ? is the output only 50w?
Yes you cannot screw up your speakers unless you put too many watts to them. These amps will not do that unless your speakers are rated below the water.
could i use for 2 small speaker and 1 for center speaker ?
These ants are not meant to be a surround sound system for your TV so there is no Center channel. I will look into it and see if I can find something that will work for a surround sound system. So far I have not seen anything available but I will keep looking. Thank you so much for watching.
which song was that you played first?
It is simply titled let's go.
Great video, nice explained it. Question; I do have a pair of DCM KX 10 speakers (4 ohms) can I run my speakers and a powered sub with this BT-30A? Will be any power problems because speakers are 4 ohms?
No that should work great. Hope the video was helpful, thank you so much for watching.
@@hanzdidit Thank you!
what active or passive woofer can you recommend for Fosi under $200 ?
Any sub will work, the best deals I have found on facebook market place or Craig's list. This one look good for $149.00 amzn.to/3ySVREu
I hope this helps, thanks for watching.
Can use with active speaker?
Edifier 1700bt
Sorry for the lat reply. These amps are built to drive the speakers so you do not need to have a powered speaker.
Got it today! It’s making a popping sound when power is turned off. Is that normal? If not, how do I fixxit? Should I return it? Thanks!
That is normal I wouldn't worry about it if I were you. Hopefully you like the video thank you so much for watching.
@@hanzdidit Thanks for answering my question and really liked the video of your review!
Just bought one. Hooking it up to a pair of JBL C1 pro speakers and a JBL LSR310s subwoofer. Hopefully it'll be more than i need for the room size!
So far I've been so impressed with all of these amps, let me know what you think of the one you have. Thank you so much for watching.
@@hanzdidit bought the fosi BT30D. Works beautifully with the C1 pro speakers and the LSR310s sub. Difficult to believe that such a tiny amp at such a reasonable price can yield such good sound!
My big question on the BT30D is whether the Sub Freq (subwoofer crossover frequency) adjustment is only a low pass crossover for the subwoofer low-level (RCA line level) and high-level (powered) outputs, or if it also serves as a high-pass filter for the main L/R high level (powered) outputs.
Yes there is a single adjustment just for the low pass / crossover for the subwoofer on this amp. There are separate trouble and bass adjustments for the speakers only that do not affect the subwoofer. Hopefully this is helpful thanks for watching.
@@hanzdidit Hanz, continuing from above question/response, so are you saying the sub freq control adjusts the low pass sub crossover frequency and, at the same time, adjusting any potential high pass to the main speaker high level terminals??? Or are those speaker connections always playing full range regardless of the sub freq setting? Thx for your input
@@brianchristopher4666 no he said the opposite. You can turn down the low frequency volume in the main speakers using the bass adjustment control only. The sub frequency cutoff frequency control controls only the sub channel out not the cutoff on the main speakers. I imagine that would require a much larger and more complicated board.
i like the test And explain to know the fosi sound. If there is a Thai explanation too, that would be great.
I have a few more videos coming out hopefully they will shed some light. Thank you so much for watching.
Does master volume turn down subwoofer volume as well?
The main volume turn step volume down on all levels.
I got the BT30D Pro version yesterday. I connected a passive sub and speakers and it started running quite hot. does ur bt30D run very hot with speakers and sub connected?
Mine did not seem to run very hot but I have not tested under a load for a long period of time. It should be OK but he might try it for a few days and if it still seems to be getting hot contact the seller and see what they say. Thanks for watching my video and supporting my channel.
1 month late answer.
just discover u shud not use 24v, try use 20v adaptor and 8ohm speaker.
Thanks for ur replies. Well it's been a month now. Its still working fine. Maybe coz the design has no ventilation. So far no issues except for running hot. 🙄
How do I connect my Echo Dot to this?
You can use something like this to connect the Amp to the dot. amzn.to/3hI4SvD
Does it come with a remote?
This one does not come with a remote. There are a couple of them that I have ordered if you go to my playlist you can see which one does. Hopefully this video was helpful, thank you so much for watching.
Thank you for your great video. May I ask you a question? Do you think that the stereo speakers are filtered to send the lower frequencies to the subwoofer only? My concern is when connecting small stereo speakers that are capable only for mids and highs, and should not receive bass frequencies. Can you control this withs the bass a treble knobs? Does these knobs actuate only for the stereo speakers?
Thank you!
On most of these amps the base and the sub for the stereo speakers are separate from the subwoofer. You should be able to adjust the base in the travel and the sub separately. Hopefully this is helpful thank you for watching.
Turn down the bass knob for the L/R speakers, and adjust the sub frequency to slightly overlap the L/R bass. This way the sub takes on all the lowest frequencies and the L/R speakers take over for the high bass/mid/treble frequencies. If the L/R speaker frequency range is 120Hz - 20Khz you would want the sub knob to roll off its frequency at 120Hz and handle everything below 120Hz.
@@DanLimbach thank you !! Great response.
@@DanLimbach thank you!! Very useful answer.
just bought it a week ago.
tested and its just 20watt x2 + 50watt sub.
its sound OK, not too good not too bad.
I totally understand what you're saying but you have to compensate for the size lol.
Do you have the older BT30A which has a weaker 3116 chip? That would explain your 20wpc. The PRO version has a much more powerful 3255 chip and puts out 60wpc@8ohm, 100wpc@4ohm.
to alex z the white rca input on the sub
To my understanding the RCA jack does not matter what color it is. RCA is RCA
@@hanzdidit the white is lfe in on the klipsch sub
Does main volume lower sub volume also?
On this amp it does lower all the volume.
@@hanzdidit so both volumes are not independent from each other?... main volume acts as a master volume
@@ziggy8757yes but you can control volume and frequency for the sub from the amp, so you have total control
great reveiw.
Thank you so much, he made my day.
I also bought the
fosi Q4 headphone amp
Nice, which one do you like better?
@@hanzdidit both
x9 pls
I am not sure what the X9 is but I will definitely see if I can get one.
@@hanzdidit the pitbike
I just got the Fosi Audio BT30D amp to power my speakers and sub. This doesn't have a DAC but I do have the FIIO Q3 headphone amp/DAC. I was going to use my TV Sony 48A9S aux out to Q3 to the BT30D. Is there anything wrong doing this? To power my speaker components and passive subwoofer?
No I think this would be a great amp for what you are using it for. This is the one I use in my speakers for my stereo and it works great.
I got this, checks a lot of boxes, and works great to fill my 15x20 foot room. The sub makes it work fantastically, but I have to turn the bass up a bit too much for it to get the real kick. Heck, it sounds great, with lots of volume, I just wish I could push that little bit extra without overdoing the bass.
My speakers are rated at 75W 4 ohms, so I would like this but at 2x75W plus sub. Seems all these mini amps are 2x50. There are boards that do 2x80 or 2x100 plus sub, but I'm not really into building.
My cables are 30-foot long cheap CCA 13 gauge, would getting better quality cable matter here?
Speaker wire does make a difference especially when you are trying to get a lot of volume. My suggestion would be to use a powered subwoofer that way you can adjust the amount of base that you're getting directly from the subwoofer and not relying on the amp alone. In the video I show the amp running the subwoofer which works great but if you're not getting enough base you will either need a larger subwoofer or a powered subwoofer. Maybe try new speaker wires first and see if it makes a difference. Thanks so much for watching and supporting my channel.
Sorry I did not get your last message, let me know if you have any more questions.
@@hanzdidit Thanks for your reply. I'm using a powered sub, and what I mean is - sometimes I want to get 'louder than max' (as my speakers have another 25W to spare), and then I all I can do is turn up sub volume on the BT30D (or up the crossover frequency), and then of course it can get too bass-heavy.
I'll try getting some good cables and see if it makes any difference, as mine seem to be in the 'crap' category.
After that I'll just wait around for a more powerful such product with matching features to appear.
@@hanzdidit Would you say that the Douk Audio M1 Pro could be a "better" alternative to the BT30D?
not sure if you still check yt but the pro version of this amp would proabbly do what you want
When you run rca cables from the TV to the amp, we haven't been able to control the TV audio with the TV remote. Any idea why this may be? Seems like it should control it.
I think the volume would have to be controlled by the external device that you have plugged in. I would try using a headphone jack if your TV has one that would probably work off of the TV remote. Hopefully this is helpful, thank you so much for watching.
@@hanzdidit Appreciate the video
