100w Cheap Mini Amp - Wuzhi ZK-502T Unboxing Assembly and Test

[@ayeapprove]

I have this and while it's noisy it's amazing for the price I paid (less then 5 USD). It automutes after a second when playback is stopped but you can still hear the noise in this 1 second.

[@abdalmoman9572]

Thanks for reviewing the widget. I've been wanting to get it to try it out

[@tramach4030]

Hi bro, compare the sound quality of 4 speakers (2ohm 15w) with 2 speakers 30w (hk 3inch). Tks

[@vdsmade]

👷‍♂️👍

[@ismaelsantana422]

Sabes Deberías hacer uno con el componente que tiene L y R 220w. +Subwoofer 350w

[@aaronv3859]

i have the same one but my aux input does not have stereo, but connection over bluetooth has stereo. did i got a faulty unit?

[@dmrezwan2010]

yes cuz the original hass stereo in all inputs

[@garengaren6573]

Hi good review bro btw can I use 2 8ohm and 50 watts speaker to the amplifier?

[@scellysspeakers]

Yes that will work fine with this amplifier

[@rioa.s2006]

​Recommended power for this setup? 19v 5a maybe? ​@@scellysspeakers

[@scellysspeakers]

@@rioa.s2006 That will be fine for most stuff

[@newbiebelajar7488]

Menggunakan speaker apa kak...? Berapa watt berapa ohm dan berapa inch

[@KEEVVY]

I wonder why don’t they make a real box for it

[@nsat4396]

Thats why its called DIY..And its cheap..A complete set with real box will make it pricier..

[@45Fps_XTR]

Where did you order this from? I want to order it too. please ❤

[@scellysspeakers]

I bought it on Amazon

[@JuanPaulo79]

Hi, Can you show us what you did for power source?

[@scellysspeakers]

I used my bench power supply to power it with a DC jack cable connected to it. You can see what it looks like here kzbin.info/www/bejne/fqaxd5Von5eKb8k The model of the power supply is xys3580, I use it for testing things but not for powering things full time.

[@JuanPaulo79]

@@scellysspeakers Thaks, Got it. what do you use to power, full time?

[@scellysspeakers]

@@JuanPaulo79 At the moment only that power supply, I bought this amp for a future project that will be powered by a 12v DC power supply.

[@agn855]

@@scellysspeakers- Hi, I'm using an (obsolete) 19V HP Notebook charger that comes with a matching connector. As (as far as I remember), the device is able to handle up to 24V, so it delivers enough OMPH. It’s connected to a pair of B&O speakers and I’m using it for Amazon video sessions. Nice

[@Suhendri5150]

Bagus mana suaranya sama jk tb21 jika jk tb tida menggunakan subwofer.!?

[@scellysspeakers]

They both use the same amplifier chips but the TB21 has additional components to support the chips, such as more inductors to filter the output.

[@Chinhnguyen0497]

what is the different with all wuzhi models? they are so many, thats why I not buying it yet

[@scellysspeakers]

Different outputs and different chips, ZK/MT-21 are 2.1, 502 are 2.0 etc, search up wuzhi and see what comes up

[@travisdonley8768]

You should do a review on this amp. Would you say it's a good value?

[@scellysspeakers]

I'd say it is very good value if what's most important is the connectivity and power output. It's very clearly not something for audiophiles but it meets all of my expectations for the price, and I think it's perfect for home theatre stuff.

[@travisdonley8768]

@@scellysspeakers Thank you!

[@frankp1174]

Is the sound good when using the mini plug input? Some people complained that the treble is lost when using this input.

[@scellysspeakers]

I haven't tested it but the sound will be somewhat changed because the aux input is converted to digital and back by the jieli chip responsible for audio decoding and things like that. The 3.5mm input does not go directly to the amplifier chip, but is processed before it goes there. I will test it when I get the chance, currently I have this amplifier in storage for later use in a project.

[@frankpowde5200]

OK, thanks

[@NoneYaBiz200]

Yes i found the same thing. This issue has been reported on ASR. So apparently, the ap3050d chip with no tone controls has an issue with the aux input where the highs are rolled off but the amp with tone controls has had this issue fixed. Now, the amp with tone controls also features the 3116 with output inductors instead of the ap3050d, so I wonder if it is the chip or the tone controls which fix the issue. This amp has the 3116 with the inductors as you can see in the video. Let’s see if someone can bring more info on this issue.

[@Malsawmakhiangte84]

Can this amp handle two sony ss-rv999 speaker 100+100 watt?

[@awie9255]

No

[@ffadeawayy2199]

hi will 12v 6a dc work ?

[@scellysspeakers]

It will work but you won't get the peak power output, it may distort at high volume.

[@ozanaltnsk3967]

Bas ve tizler nasıl ses kalitesi nasıl sizce yorumlarmısınız

[@scellysspeakers]

Ses kalitesi muhtemelen basit bir D sınıfı amplifikatör için alabileceğiniz kadar iyidir ve bas ve tiz kontrolleri çok etkilidir.

can you help us audio amplifier T200w do a review on youtube,thankyou!

If you send one over maybe

[@SamsMediaCenter]

Can you please share the link of the power supply you used? I am having hard time finding good power supply for these amplifier boards.

[@scellysspeakers]

In this video I used a variable "lab" power supply (xys3580) which I only use for testing, ideally you would use a proper purpose-built DC power supply. Something like this would work fine www.amazon.co.uk/DTK-Charger-90-240V-Switching-Transformers/dp/B07K85GJ54/

Power supply name please I use this amplifier but my power supply get to much hit

[@scellysspeakers]

You can use any 24v power supply with 3a or more for realistic power output, it uses 5.5x2.5mm center positive DC jack
