Clip limiter

[ionutzxpo]

hello,can someone please help me with a clip limiter circuit

thank you😀

hi.

do you mean a clip indicator or a audio limiter to lower the input signal?

hello,i mean a limiter to lower the input signal 😀

hi.

i dont have any schematic of a limiter who works well. but i have used the clip indicator from ESP project23 it works great.

i have used the clip indicator from ESP

Me too, but this is not limiter, but good way to start if nothing else

I used a resistor with two zener diodes to limit the input voltage

Some pro amplifiers use LM13700 transconductance op-amps for variable input attenuation. The LM13700 is normally off. Consider getting some schematics and study how this is implemented. You can start by looking at Behringer EP2500 schematic, a well known one. Then you can study others from QSC, Yorkville, etc...

An alternative to LM13700 are light dependent resistors (LDR) and "Vactrols".

You could work on the amplitude of the triangle wave, increasing it to clip less. (assuming your design is clocked)

LIMITER

hi
greetings there is a working limiter with pcb on solid state thread on page 8
vertex amp thread page 7 post 61 using ic LM13600 LM 13700 also can be used
qsc uses this circuit only mods are instead of 1.2k resistor 1k prest can be
used to limit voltage to 1.5 volts
hope this helps
warm regards

Thanks guys,especially Eva
I found the vertex amp thread and i found the LM13700 on local part's shop in Romania
(i think that LM13700 in the vertex circuit work as a compressor to)
Thank You
