Help, with ashdown....

[Juanchito]

Hello Guys, good day....

...does anybody here owns an Ashdown Little Giant 350W/1000W... is it Natural that at first the "FAN" isn't running or totally not running...but works well, or should it be ruunning already the minute i switch it on....

thanks guys in advance...

It might be a variable speed controlled by the temp of the amp? I can't say because I don't have one. However, a ton of the micro electronics I work with have fans like that to conserve power.

Thanks Joe,

i was thinking the same way that maybe if the heat goes higher it will turn on at some temperature, but i really have no idea...but 'nway thanks, your relpy is enlightening ( im an alien to the amp world )

thanks Joe....

Hi.

If it's a class D amp as the manual says, the efficiency is greater than 90%.

It means that the cooling requirements are far less than with an AB 50% efficiency.

One could draw a conclusion that the fan control should be variable and only used if the heat sinks capacity is not enough to dissipate the heat produced. Which is for example ~10W with 100W continuous output (vs. ~100W for A/B).

I'd guess there's a fan control, about the only way to find out is to contact Ashdown and/or crank the amp .

Regards
Sam

I have a Superfly 1000w, and the fan on it only comes on if the amp is running hot. Must be some sort of thermostat control in the amp.

I tried one in a shop, and when it started up the fan would come on for a second, then stop, I'm guessing that It would come back on if the heat rose.

Hello Skywalker,

..maybe ur right, coz when i was looking for a superfly, this is the one they gave me, they said that they've already stopped reproducing the superfly...maybe they have the same mechanism...

...well i gues i'll take ur word on my problem...

...thanks Sky, thanks guys....
