The sub frequency nob on the left is a lowpass, not an eq. It will play frequencies below the chosen frequency and decrease the volume of those above. The sub volume right next to it increases the volume of all sub frequencies
Subwoofer frequency knob is not the same as what you showed on the equalizer.
On the equalizer, you adjusted the Q, meaning increasing the gain of a specific point of the low frequency.
On the amplifier, bass frequency knob is a low pass filter, meaning what frequencies you want to send to the subwoofer and what frequencies you want to send to the satellites. A value usually from 80Hz up to 200Hz (give or take, depends on the manufacture).
So when adjusting this knob, you adjust the cut of frequency to the subwoofer, nothing to do with gain.
@Goodmusic210 It’s very easy to find out.
Turn the knob all the way to the left and listen to some song, you should only hear the kick from the drums and some base notes coming from the subwoofer, watch also the movement of the driver, you should only see it move with the kick and the very low frequency base notes, then turn the knob all the way to the right, many more notes should be heard, the sound become more bummy and the driver will be moving in and out like crazy. Best to do it without any satellites attached. That way, you will be able to hear more notes of the song being played through the subwoofer.
If it is an equalizer, you will hear the same notes on all positions of the knob.
If it is a Q style equalizer, depending off the position of the know, a few of those notes will be more boosted. Such an equalizer usually have 3 knobs, one to choose the midpoint of the frequency, one to choose how wide or narrow the slope will be (the range of frequencies to be boosted) and one gain knob. But I have never seen a Q equalizer on such a device.
If it is a normal equalizer, (often called bass boost) you will hear almost all notes been boosted.
In both cases, all notes will be heard all the time and get boosted depending on the position of the knob.
@Goodmusic210 so it is bass boost or crossover? Want to buy one, but prefer if it will be crossover. Could you be so kind to answer.
Can i use a 24v 5a power supply for this specific amplifier?
Thank you! i always enjoy you video's. Because of your enthusiasm and passion. And bought and have many of the products you review too.
I guess for me it is just enjoyable to see what quality of sound and suprises you can get from some of these products. It exites me more then spending it all in one (expensive) amp that you should expect high performance from.
From what I see and get that the same goes for you.
For adjusting the subwoofer to the wright frequency you can do it by ear. It works too but is more difficult. The progam you used is very helpfull.
If you know the bottom frequence of your main speakers. Lets say 60hz you adjust your subwoofers crossover starting from there. (I think that would be about 10 o' clock on the frequency dial of the amp)
A little higher is advised, 70hz (something like11 o' clock) for example that way it helps the main speakers with the bottom registration. Most speakers will reach the specified bottom frequency but it is measured and sometimes not completly audible.
If you do this wright you should hardly notice the presence of your subwoofer and appear like your main speakers are actually producing the bass.
If you still notice the sound coming from the subwoofer reduce the volume until you can't locate the bass. It will be a seemless transition that way.
I hope you don't mind that I shared my thoughts and experience on this.
I will continue enjoying what comes next!!
I really appreciate your comment and I am very glad for your support! Thank you a lot!
@@als-techreview Thank you! And you're welcome!
Thanks for the video, got my eye on one of these
The question is: can you throw a party with these? :D
Gracias 🎉
Is this not good for headphone?? I bought 1more quad drive earphone and triple drive headphone.. Will this amplifie them?? I don't understand
Is it similar to the one called Fosi Audio BT30D?
Yes
Hi brother from another mother, from another country. Cheers 🍻. I hope you can help me. Because I have this speakers from pioneer s-ev9v and it’s amplifier is already gone. I know it’s not related on your video. But, I’m looking for an alternative amplifier. Do you have something in mind? I’ll appreciate your answer. Here’s the specs.
It’s a 5.1 system.
This is what says on the back of each speakers.
-100w 6ohms Front Left
-100w 6ohms Front Right
-100w 6ohms Surround Left
-100w 6ohms Surround Right
-100w 6ohms Center Surround
-100w 6ohms Subwoofer
Someone told me about an amp with tpa3116. So I searched and found “Aiyima A9” and that’s how I got into your video. Thank you and godbless
This amplifier can't support aiwa sx-ans90 with impedance 6 ohm?
these amps dont have a detent position in the bass and treble controls and thus its hard to say where they are flat
Thank you.
Hi, Just bought one of it, but subwoofer is not working, get no signal out of the amplifier, ¿does it has to do with the power input wich is of 19 volts at 4 ampers? just would like to know if it wort to get the 24 volts, thanks in advance.
Hi does the sub freq only adjusts the subwoofer or the main speaker bass as well?
As the name imply, it only change the frequency of the sub output
hows the bluetooth connection, does it have lag? can i use it with headphones?
Hi, can this power two 12 inch 1200w rms car subwoofer?
kKkk
How is the bass on the 2 speakers without connecting the subwoofer? Is the subwoofer output for 4 or 8ohm?
can you connect 300watts sub.directly with that without pre amp or crossover?
Sure.. It should work with no problem.
That's about right, hear the difference, but it sounds like it's still starving for amperage on them bass notes or is the speakers choking?. Is that 4.5 amp? If it is I don't want one, wait I re-watched the video and they only gave you a 3 amp power brick 0:52 I want one if they include and supply the correct power brick. Simple math 100w divided by 24v = 4.17 minimal amperage, so 4.5a is correct when wired to 4 ohm speakers. You wont get 100w from 6 ohm speakers with this and 2 ohms will make it overheat because the heatsing can't dissipate the heat, but if you have with 5amp you may get 120w. I would open it up and remove that heatsink then use a thick copper shim with some Arctic Silver 5 and mount the shim on it and most importantly making sure it touches and presses against the top plate of the chassis, not too much pressure, just 1mm away from the top sitting flush and press down and mount the screws. This will cool it so much better and will help with the THD Total Harmonic Distortion at top end . I may even use 3 ohm speakers and I'll have better headroom at lowwer volumes without any breakup using 4 ohm speakers, this makes the amp cleaner. You should know most all of these Class D amps have 10% THD at top end so I use 50 to 75 watts or lower for best results and it will sound awesome. Make sure there's no shorts anywhere.
Question, I have an Aiyima Amplifier and for some reason it hooks another external devices and obviously unable me to use it, there's any way to force an unpairing to release it?
Does this version have noise at higher main volume? Does it have pop during switch on/off?
Probably the better of the bunch.
How to correct power adapter plz
24v but 1.5A.
I would have preferred atleast 3A like the Nobsound and Lepai..Lepy systems. Anyways thanks for the demo. I need help as to which one of these 2.1 chinese amps should i buy
No problem.. Nobsound and Aiyima they are both good products..
ALS-TechReview thanks a lot for the quick response 👍
Roots. You wanna get the 3255 chip. I believe this aiyama has it and not the 3116.
@@FreakishPreacher thanks pal
How about 2 ohms subwoofer jbl 1200s ????
What if i don't have a sub woofer? Can my 2.0 speakers still produce quality bass?
yes
Hi there.. this amp is also for 130watt speaker?? Thanks
sure you can connect on those.. 👍
I don't notice a difference. Sounds the same to me.
Can I connect the sub out to an active subwoofer?
As long as your sub has low level inputs, yes.
@@catharticcathexis4527 thank you , do u mean I can connect the A03 sub output (both speaker wires) to active subwoofer ? My active subwoofer has speaker wire input (for left and right speaker).
Hi! Does the midrange speakers automatically adjust the lower frequency limit with subwoofer control knob?
지금 사도 괜찬아?
Kahan Milega yah
If people don't know the difference between frequency and volume then they don't need to listen to music and need their ears cut off!
This is so true, they might as well listen to a monotone singer at scaraoke night.
I only have 20 volt 4amp power adapter, will this work with it?
@Suripat Patsuri i alrady bought 2.1 amplifier and tested it with 20 volts adapter. Yes it does work great sound clarity, crisp and powerful! Paired it with my old Onkyo bookshelf Liverpool and DIY 250 watts sub.
Friend, can this amplifier be used if I connect two speakers and do not connect a subwoofer?
Ofcourse it will work 👍
@@als-techreview Doesn't the amplifier break?
Hi , are you connecting passive subwoofer?
Suripat Patsuri yes , I purchased it and tried with passive subwoofer ! It works beautifully with the help of a little subwoofer freq and volume adjustments. It’s amazing that the amplifier temperature remains low. The connectors behind are also high quality. Worth the money .
