Current issue

[miner]

My system consists of:
Rotel RC-1070 pre
Rotel RB-1070 amp
Rotel RCC-1055 CD changer
B&W Nautilus 804
B&W ASW 800 sub (1000 watts)

Last night while having friends over and blasting the system I noticed the lights would dim slightly when the sub would hit hard. Should I be concerned? Any easy remedy?

Should I be concerned?

Not too much... it doesn't mean that the amps are lacking energy.

Any easy remedy?

Not too easy... you could have an electrician run independant outlets for your system only. At least one for the sub and another for the amp. It would help, because your lights must share the same wire run as your systems outlets.

Thanks Jim777. I did not experience this until after the sub was added.

The interesting thing about electricity is that the power system in your house doesn't have any reserves. So when more power is needed it get's pulled from where it can. Your amps, however, do have reserves so they are just pulling to replenish them.

A lot of times, the lights in a room are powered off of the same circuit as the plugs. So Jim's suggestion of having a dedicated outlet should solve the problem.
