hi,
I apologize me for my English ,
I am using traslator .


I am interested in the class H of phonic max-500

in the photo give only three couples of BJT endings,
I think toshiba 2sc5200 /2sa.

he should have only 200 W rms 8 Ohm, it has 500 of them instead ,
Why?

have you felt him/it play?

Does it seem yourself to fine play?

I would like to read in detail the scheme.

Ciao !

Default Hi Sandro!

Shematic of MAX-2500 has been sent.

Yes it is H class power amp.
Lower power is driven by BJTs and higher pow is driven by N-chanal MOSFETs.
Study the schematic carefully, it is very simple.
Reply me your opinion.

Hi Zeonrider,

thanks for schematic, it is very detailed, but the idling current value is not suitable .
reading it scheme, it seems me that this is ampli is not in class H , but in class G , also Yamaha M80 and mx1000 ( supply low 40+40 volt, supply high 90 +90).

Max 2500 have supply low at 55+55 , high at 100+100 , besides
the superior voltage is manged form any one mosfet, instead of a double couple of BJT ( yamaha mx1000, what it also has three couples of toshiba on low supply ).
Until here everything well,
but I believe that the phonic has a weak point that is the smalls condensers ( 10000 +10000 in series = 5000 mF ) and 3300 on the low supply .
The Yamaha MX1000 have 47000 +47000 in high e 40000+40000 in low supply. It have 380 watt RMS 8 Ohm .
Thing you think of it?

Sandro

Unhappy another blown phonic max2500

attention: Zeonrider, Sandor626

need help, I have a blown phonic max2500 in my shop, some parts (resistors) were burned even the pcb markings were charred, it would be very hard to identify the burned components, I would like to ask a copy of its schematic diagram and if possible the copy of its parts placement guide please. Thank you very much. Have a good day everyone.

P.S. I still like the phonic Mar series and the Xp series they are really tough amp.
P.S. I have seen the new phonic dmx series, the board were the QSC RMX Series just like the Beringer EP2500. Can someone enlighten me on this. thanks
