Mic, Line, EQ... Preamps

Here is my ML3. Will test for first time this Tuesday after a long weekend here.

I'm hoping to use it for a PA at work when we have larger gatherings into a single speaker and dual mono into two speakers with two amp modules..

I have a 12inch woofer and horn compression driver. Still need to find a two-way design for a speaker box.

Regards

Mile, i hope you still monitoring this thread.

I have no one else to ask.

I have a 12inch Hybrid speaker and a 1in Hybrid compression driver. I want to build a 2 way box for this combination. Any ideas ?

Hybrid HT-60 Compression Driver:
1″ Exit
8 Ω
60W RMS
50mm Aluminium VC
107 Db 1W/1M
Freq: 1800-19000 Hz

Hybrid 12H400 Woofer:
Impedance 8 Ω
Power (AES) 400W
Voice Coil 100mm
Magnet 123 Oz
Average Sensitivity 97 dB 2.83v @ 1m
Frequency Response 36 – 2500 Hz

Only data i could find was for the mkII version of the speaker

Ladies and gentlemen of the group, all good to you, if anyone can ask me a question I would be very grateful, what changes will I have to make to the APEX TB3 tone control so that I can use 20k potentiometers instead of 20k and keep the same characteristics I have many 20k faders and would like to use them on this board. Sorry for my bad English.

hi do you have the pdf of the amp that you built
 
project mixer

only one board(signal in) tested and worked fine. ouput and phone pcb are not tested but will work fine.for full mixer you need desire input channel and two l and r output module they are same but only difference in jumper wire and ic 2073 can be replace with tda 2822.one can use phantom 48 v with nc point and one extra switch.enjoy.
