- How long have you use it?
He has served only two times: once in the new year and another in the evening of July 2003.
Compared to the PA2200 served every evening.
- What is so special that you like most and least?
It was cheap to éopque it helps out, he does not like high hps BL
- Have you tried many other models before buying it?
PA2200 except at the time not.
But then: there is a design change between PA2200 and PA2600 one, so I write this review now.
- How would you rate the quality / price?
Not good indeed, but the worst when you know why you will roar with laughter ...
- With experience, you do again this choice? ...
No!
Differences in design-PA2200-PA2600:
PA2200: single power supply 60 Volts 250VA 10000μF
PA2600: double secondary transformer power transformer not shown 4700μF 94Volts
So here:
At Boost we are a bit silly: we forget that a single power supply is better for the bridge, for example, to distribute the current between the condos.
In fact on the map of the PA2600 amp, two power transistors have been removed: balance the races: the current protections are activated by the voltage detected on the emitter resistors, suddenly, it loses power in gross phase:
to save four transistors, we therefore gun down the perfs of the amp. Bravo.
Then the transformer'm not really I think this is a 1000VA.
Transformer ref:
048-00300-001
2002
In short, this amp was deliberately restrained, which is still quite annoying.
For me the fan is normally fixed on the two sinks amps: no strange attachments in mine.
It is clear that the choice of a separate power amps for an amp is economy class, something stupid.
It's still the only class that I saw AB +-94volts supplied, which is huge: the amp heats up and it makes perfect sense (it has never cut, even in saturation at home into 4ohms).
The only possible upgrade is to the switching modules in fact.
It's a shame: a transformer with a similar setup in class H would have given much better results at a cost not really higher.
Having removed the power transistors on the amp that this mark (KoolSound) is banned: there was therefore a misdeal between PA2200 and PA2600 sale.
