Mr. Miles,

Is this Terminal Protect will work with AX-14??

It does with this one:

Thanks 44250....

hi apex sir,
i finished the vu meter,left side with 21 leds -right side with 21 leds. its very high resolution vu meter, but when i increase the volume to high, the top 4 leds not lightning, including the clipping led also not lightning. where will be the problem?

tomorrow i will post the pictures.

Use 220R resistors instead 560R for vu meter with 21 leds, but amp rail voltage must be about +/-75V (over 30V voltage drop on 21 leds)

Mr. Miles,

Is this Terminal Protect will work with AX-14??

Yes, anti-click, thermal and DC protect will work, but with AX-16 overcurrent protect will work.

 

[wiljj78]

Yes, anti-click, thermal and DC protect will work, but with AX-16 overcurrent protect will work.

Thank you sir...

Mr. Mile,

I would like to verify if this regulated PSU can drive stereo AX-14?

hi apex sir, here is the video, only one side finished.
tomorrow i will change the resistors to 220r

hi apex sir, here is the images.

Nice work, increase the value of 1k2 resistors and the top 4 leds will lightning.

very good topic
thanks to apex

and the top 4 leds will light.

hi apex sir,
i tried with these resistors 1k5 , 2k2 , 2k7, 4k7 ,5k6 -but top leds not lightning.

What is rail voltage on your amp, with low rail voltage you can't use 21 leds

 

[wattaniya]

dual supply 50v dc.

 

[apexaudio]

dual supply 50v dc.

Voltage on 21 leds in series conection is over 30V... I suggest to use about 12 leds for amps with +/-50V rail voltage.

ok sir , what about top last led resistor 3k3?
can i use this vu meter for b500 and h900? any changes?

VU meter can be use for any amp without changes.

ok thanks sir, u mention before somewhere over 75v dc, one of the resistors should be 2w resistor. i cant find which post is that.
