Amp impedance question

[Pwnasonic]

Hello!

I got my 1st amp (audiolab 8000SE) few weeks ago so Im newbie to all this things. When reading specifications of amp and speakers it says that amp runs 60wpc into 8 Ohm, 95wpc into 4 Ohm but how do I know in how many ohms is it running currently and is it possible to switch between 2 modes somehow. My speaker's nominal impedance is 6 ohm's so if i didn't get things wrong amp should have same or lower imp. to run them correctly. Thank you for any help!

Impedance is a measure of resistance to the flow of current. The amp power specs tell you that when the resistance is 8 ohms it can produce 80 watts per channel and when it is 4 ohms it can produce 95 wpc.

The nominal impedance of a speaker is an average over the entire frequency range it can produce (impedance varies with frequency). A nominal 6 ohm speaker will dip well below 6 ohms as well as rise well above 6 ohms.

When the impedance is low, the amp must supply more current so 4 ohm speakers are harder to drive because they present less resistance. It's kind of counterintuitive. If the amp is rated for 4 ohm loads it should have no issues with 6 ohm speakers.

Thank you for reply. I asked that as for some speakers (Quad) in spec. stands 6 ohm than in brackets 8 ohm compatible. That confused me so had to ask. Thanks once again!

As always MDS is quite helpful.
