Warm up of active systems
Posted by: Emil F on 28 April 2004
It is about the 3 amps in an active system. After moving the system I'm not sure that each amp is driving the same drivers.
Did somebody notice some changes after switching the amps, for instance bass amp powers the tweeters, mid amp bass drivers and HF amp mid drivers?
I feel that an amp, which has powered the tweeters so far and was moved to the bass, needs time to warm up. Is this correct?

All the boxes were switched off and moved away.
I would like to know, if the amp, which was used to power the tweeters, is fully broke in to drive the bass or it needs the usual warm up time of a new box?

Emil,
I would say the amp need somewhere in between.
The amps have been switched for a while and will need warming up again. It won't take as long as when they were new but they will take time to settle down again.

Do you think that an amp, which has driven two tweeters for 10 months, is ready
to drive 2 x 15" bass drivers? My point is that it needs maybe 6 to 8 weeks for that.

Its possible that may be the case but IIRC JV said that active systems need six weeks minimum to "warm up" after being powered down (for a period of time - not just a few minutes). This not from new but after being fully "broken in".
My experience with my active system (after moving) confirms this. Its performance was sub par for at least that period. Fine now though (four months later).
Have patience (frustrating as it is).

Emil,
I remember having some friends round who were really underwhelmed when I connected up my six pack after running passive for a while. It in no way sounded like it was worth the extra X ammount of thousands of pounds that the six pack cost. Hey-Ho it did come good eventually.
I was always told in the past to listen to the amps individually, passive, and put the best sounding one/s on the treble, then midrange then bass. If you have a passive x-over for your speakers you could always try it even though it is a bit of a pain.
