ANLEON S2 MOD

Modified this low cost wireless In-Ear Monitor. Added a volume control of audio input.
The original lacks and sometimes supposes that it reaches distortion and is a source of noise.
I have also modified the response of the compressor.
This equipment has a good quality/price ratio and I think this mod makes the most of it.
Enjoy

Hi! I've tried out the input volume mod and it works. Thank you very much for your videos!

[@prouting7333]

Glad it works for you. Thanks for your feedback

This is a very nice an good mod and testing evaluation. Good job. I just like to be shure... in the video at 9:24 You wrote; This position was most succesful... I asume that You refere to the POTM connections on the lower right corner. But on later videos I only see the connections at the input, where the 0 smd resistor was?. Can You please send me a picture with latest mod that is the best working. Thanks again for great video.

[@prouting7333]

Hi, Thanx @flemmingandersen420 Yes, finally I only use a single potentiometer, which I place where I remove the 0 ohm resistors at minute 4:02. In the third part of the video mod, instead of the second potentiometer at the compressor output, I replaced it with two fixed resistors. kzbin.info/www/bejne/q4amhHZnqZhgqMk There you will see clearly where the input potentiometer and the resistors are located. If you are interested in modifying the receiver, I leave you this other mod in which I change the behavior: kzbin.info/www/bejne/g5W3eIOFidKMY80

I saw this in my feed after watching a Scott Uhl video yesterday about this wireless unit as a cheap option for In Ear Monitors. It is a lot of trouble to go through to add those pots, but it is great to see you have that know-how and show others what they can do. Maybe I need a link though to find the components. Thanks.

Thanks Mark. You must have some practice for soldering on small components. You need: Potentiometer B20K es.aliexpress.com/item/33055577453.html?gatewayAdapt=glo2esp Cable shielded 30AWG 3Cores es.aliexpress.com/item/1005001460352780.html?gatewayAdapt=glo2esp Some Knobs es.aliexpress.com/item/1005004331673820.html?gatewayAdapt=glo2esp In a second part I do a test how it sounds with the modification and a schematic ;)

[@k.t.ingram375]

do you know how to bypass the limiter? trying to figure it out.

[@prouting7333]

Hi! Check out this other video kzbin.info/www/bejne/q4amhHZnqZhgqMk There I tried to bypass the compressor but the result is not satisfactory because the sound becomes gated

[@prouting7333]

What is better to add a potentiometer at the input of the compressor and ratio modified. In this other video you have a sound test after the modification. Regards kzbin.info/www/bejne/enbXlaGZrNx0bpY

Great job bro! Could you help plz? All i need to fix in this device is remove clipping protection. As you probobly know there is an issue. When input signal is to high (especially at high-mid freq) reciever goes mute for few seconds. I would like to remove this protection. I don't mind if signal will distort. I just need to hear click track all the time when I'm on stage. Maybe you know how can it be solved?

[@prouting7333]

Hi Unfortunately removing the compression in the transmitter does not have a good result. The result is a gated sound. The clipping diodes that are on the operational input are not the problem. I advise you to attenuate the input level with the potentiometer MOD and if you want to add a capacitor in parallel for example 1nF to attenuate the high frequencies, that could help to reduce that muting effect

[@ganz_solo]

@@prouting7333 thanks for so fast reply. Actually i can't resolve the issue. When i send metal track from audio interface to the S2 there is no problem. Headphones are so loud that i can't listen to the music. But when i use it on stage it can drop the sound for 2 sec just when drummer hits hihat before song starts. And yes, usually i reduse mix bus level to -10 or -12 db and I'm not sure why i need this mod, if i can change input level on the mixer. As i mention the problem is that s2 "hears" some frequencies louder and goes to mute/protect mode.

[@prouting7333]

@@ganz_solo It is not exactly the same to lower dB at the input than the attenuation that the mod does. The potentiometer is after a previous stage that has its headroom limited by power supply (+-6V) and clipping diodes. If the transmitter's own headphone output is too loud you will be overloading the compressor stage in the transmitter. Try to lower the signal you deliver to the transmitter input more and increase the volume in receivers if you need it. If you can also equalize the signal of mix bus that you deliver to the transmitter, cut treble especially from 12-15Khz, there is another defect if you exceed this frequency the stereo deteriorates significantly

[@ganz_solo]

@@prouting7333 yeah, i always set reciever to max and send lowest possible input signal on mix bus. cut little bit of high freqs. Maybe i'll try your, becuse it's the last chance. Thank you!
