Sound system I know, has few of these, and wants them upgraded to 5002VZ spec, also with new 5002 front panel.
What is benefit of this, will it make amp more powerful? Also is there firm near London that can do it for good price? Bless Edited by YoungBlood - 08 July 2009 at 8:46pm |

What are the differences between 5000VZ and 5002VZ?

I don't think there are any differences, going by what people have said on here before. Someone will correct me if I'm wrong!
It certainly won't make it any more powerful. |

I just read the 5000/5002 spec, with the intent of putting up both charts, but saw no point after comparing power output figures. But I had forgotten how incomplete Crown macrotech specs are, in terms of 2,4,8 ohm specs @ 20-20khz on 220-230V Supply. I was told years ago, 2x2400s in bridge, is much better than 1x 5000VZ in 4 ohm stereo. Comments? |

Sure, in bridge mode, an amplifier deliver teoretically 8 times more power than one channel, but is rated like doubling the power...
from wnat I know, 5002VZ is rated for 120Volts Ac supply, correct me if I'm wrong.
The internals are absolutely the same.

+1 - WHAT are you on about?!? fancy explaining this. Your not talking in some kind of car audio measurements are you?

No, not quite right.  From figures in specs, conservative estimation of Macrotech 2400 perfomance would be approx 2200W in 4ohm bridge, on sub 30-100Hz. Which is noticably better than the approx 1770W per channel of VZ5 @ 4ohm stereo 20-20khz. The added advantage would be not needing to feed single amp in excess of 16A. |

i figured he meant... as example.. if an amp does 500w on one channel at 8ohms... it would theoretically double to 1000w per channel at 4 ohms.. to 2000w per channel at 2 ohms.. so 4000W in 4 ohm bridge mode.. which is 8 times.. 500w.
or maybe not. Edited by cravings - 09 July 2009 at 12:56am |

I was wrong, is about 4 x more power, not 8, excuse me,my mistake...
 Let me explain.
Presuming we have an amp wich delivers 80 volts RMS on each channel. Running on 4 ohms you have around (P=UxI) 1600 watts. Ok, bridging that amplifier , teoretically we will have 80 volts ch 1+80 volts ch2 , is 160 volts on output(s).
So oficially 160 volts on 4 ohms, we will have 6400 watts.
But regarding impedance variations of loudspeaker,and amplifier limitations, in the market, the bridged output, is around 2x each channels output power, also for bridging 2 channels, we double output impedance of speaker, where 4 ohms/ch, will be 8 ohms bridged.
.
Again, excuse me for my mistake,4 times (multiply)more power in bridge, not 8...  Edited by DjLeco - 09 July 2009 at 1:08am |
