Hi sir mere zk-mt21s ki 1 side ic kharab ho gayi hai ... But muze market main nahi mil rahi hai... Is board main same jo apne dikhai wo hi ic hai... Aap muze ye ic arrange kr ke de sakte ho kya? Plz reply me sir
I bought one ZK-MT21 recently. The chips are : BT : JL As21BP0C466-25A4 (but can not find the data sheet from JL). 4 x NE5532 OP amp. And 2 class D CS8673E. It works fine with good sound. However I faced one problem. If I connected it with AUX input, the sounds become mono not stereo. After debug for whole day. I found the EMI interference between CS8673E and BT chip. I have to disconnect the audio path (remove C15/C17 to stop BT chip output to main volume control) and input AUX audio signal into main volume controller directly. Then I can get stereo (2.1) output. Due to I only use it for desk PC audio, no need BT connection. So it's ok to disconnect BT chip output path (Also by-pass for AUX). But I am wondering, why this ZK-MT21 can't play 2.1 (become 1.1) when using AUX input? Does any one see the same problem? Or this ZK-MT21 use the worse EMI chips?
I have a TB-21 and face the same problem. Bluetooth plays in stereo and AUX becomes mono. I'm also planning on using this on my PC but sadly I don't have the technical knowledge and skills required to bypass the bluetooth adapter.
The output of the BT CHIP intervenes with the aux input. They share the same line. If you can put a selector switch on those lines, your problem will be solved.
The MT-21 clips words listening to audiobooks. I assume it goes into power-saving sleep during the spoken word pauses. Anyone try a TB-21 with audiobooks? ...or if you know a way to disable the "sleeping" of the MT-21, please respond.
@@timwilliams632 TB-21 also does it. The start of sentences even in youtube videos are usually cut. It's annoying especially when notification sounds are either cut or not played at all.
I won't use this for PC as I like very high quality class A or B for my home audio, how ever for car audio it's okay. Doe this have a Low pass filter for subwoofer ?😊
