HF PROTECT

Hi Apexaudio
new year greetings can your protect be used for 100 watt hf
compression drivers amplifier output per channel is 2000 watts nice project
please can you explain how circuit works
warm regards

hf protect

Dear Sir
hello please will this circuit protect my hf please help me and tell if my pcb wrong
thanking you

Pcb is OK, use heatsinks for IRFs and increase value of 2k2 resistor to 2k7 or 3k3 for smal HF drivers.

speaker setup for karaoke

Dear Mile,
Can You help me to make setup speaker for karaoke for little room about 6x8 m???
I mean box construction for 2.1 channel and what type of your amps to drive it??

Regards

Simple HF x-over with halogen lamp protect.

mile,
how many watts this x-over limiter can handle
post#66

 

[engel dela pena]

and this x-over,
will this work w/o changes with h900 amp

1200W, but with 2 inch HF driver

 

[apexaudio]

and this x-over,
will this work w/o changes with h900 amp

This x-over is for 1 inch HF driver use with 500W amp

what changes do i have to make for this x-over to work with h900🙂

 

[apexaudio]

This is overcurrent protect for HF driver, can be set with change 0,47R.

This protect don't compress peaks.

This protect don't compress peaks.

It just clips them. Won't that 10 watt resistor go smoke if you run the thing continuously in protect? DJs have been known to do that. I'd beef it up to a pair of 20 watters in parallel - and don't forget to heat sink the power transistor.

Yes resistor must be 40W if power is continuously double than maximum (25V RMS on driver), I forget protect from DJs 🙂

Protect with MOSFET instead BJT.

Apex sir,
about 3D
please share some more details.

Sir Apex,
Can we cover open front of the box shown in post #77 with some metal gril or mesh ? does this will effect the performance ?
