500W PA amplifier with Limiter

[HighTec]

hello apex, i just want to ask if i can use the b500 for my home theater sub or do you have any suggested amp to build...

Regards

Julius

Apex has left the building.

hello hitec what do you meaen by this "Apex has left the building. "

 

[TonyTecson]

^ probably apex is too busy to come to the boards and answer your questions..............

i know the feeling, when something you love to do becomes a chore.......been there, done that..........😀

 

[jon2xflash]

maybe apex could answer you questions on his facebook page

 

[jlcastro77]

i see.... anyway, anyone can suggest a subwoofer amplifier that i can build for my 400 watt 12 inch sub from the apex line of amplifiers

 

[jon2xflash]

i think you can build his quasi for biggineramp. its easy and cheap to build... but the b500 is much better for sub im my opinion . i have tried it already...........

 

[jlcastro77]

thanks jon2xflash. i might be building one b500 myself... 2 spl side firing boxes in progress. apex b500 will drive them loud for sure! 🙂

Mr mile/apex.......
Can you share to me and all of diyers schematic triple darlington

sorry mr .mile i mean is the lay out.......on pcb.....

 

[azka]

This circuit can be use to switch any stereo amplifier to bridge mono mode.
BX500 have balanced input, but without bridge option, use this circuit if you want use BX500 in bridge mono.

Ask mile :
if me will implementation with apex b500 stereo bridge to mono,share wiring more detail....
thanks
