Hi my friends! I am complete new into this hobby of building speaker boxes and after making a lot of research I still couldnt discover how to solve this question. I have 2 speakers (125w RMS - Taramps 7driver HD 250S) which have a really really really nice sound (from low-high). I built a box...

Thank you so much. One final question: why most of you guys told me I must have a very small cable after the potentiometer? A big cable would introduce a few ohms/capacitance, but why would that cause problems after the potentiometer and not before?

Hello my friends, you are so smart and kind to provide details about your suggestion! I feel sorry that I didnt explain it right: the source of my signal is a smartphone (I believe most smartphones have a source impedance of up to 1000 ohm) and the destination are two PAN8610 mini amplifieres...

I have a MONO LINE LEVEL OUTPUT and I want to share it with 2 devices (which will received the LINE LEVEL OUTPUT and use it for whatever reason). In one of those devices I need to use a 10K potentiometer in order to control the signal level that goes to one of those devices. See my drawing...

My dear friends, First of all I appreciate all your kindness and inteligence into this issue. I read everything you said and after trying all the suggestions you said, I managed to solve the problem inverting the MIC and GND in the TRRS connector. In my case, I was using GND as Sleeve and R2 as...

@Holmz Thank you for all your attention! I have a DMM but I just wanna make sure what you asked me to do: do you want me to put the DMM in the RESISTOR mode (DIRECT CURRENT) and measure the resistance between the GND of LINE OUT and the case of the smartphone? Regarding what you said about the...

Hi, When I connect the LINE OUT of my piano to my smartphone mic (TRRS) to record me playing the piano everything works fine, but there is a very annoying buzz at the background. The only way I managed to make this buzz to go away is to touch with my bare hands at the same time the GND of the...

I think the GND paths are all connected right... Maybe it's not common sharing the same power supply accross amps and pianos or line out devices? But I still cant understand what is causing this...

I have a digital piano with LINE OUT. I also have a mini amplifier named "pam8610" (cheap and very common) which has LINE IN. I have 2 power supplies, each one with 12V and 5A. When I connect each power supply to each device (one power supply to the piano and the other power supply to the mini...

THANK YOU!!

@Cachoix do you know the product name of such a headphone amp so I can look at bangood and buy one?

@Zek alright! I just didnt understand your last sentece: I cant connect my electric guitar to PAM8610 and then to another speaker (not JBL flip, but an actual speaker)?

Chrispy thank you! Regarding the flip 4 spec, I cant find it but I assume its pretty common cause they assume you can connect any p2 output from any smartphone to the flip 4 and things just work. I dont know the specs of a common smartphone but do you think using a PAM8610 to boost the signal...

Hi, I am a complete newbie in this audio stuff, so please sorry me if I say something stupid. I have a JBL flip 4 and when I connect my accoustic guitar to it, the sound is very good and has a good volume. My accoustic guitar has a pretty common 9v battery pre amplifier. However when I connect...
