Can all amps drive a 4 ohm load?


My second silly question in as many days. I'd really like to know though. Can all amps drive a 4 ohm load to some extent, or will some only work with 8 ohm speakers?

I'm using an Audio Aero Prima integrated at 40wpc, and there's no mention of the power output into 4 ohms at all. I'd like to take it over to a friend's place to try it out on his maggies, but I don't want to blow anything up.

Thanks!

Hi,

the Audio Aero Integrated selects the impedance of the speakers automatically. This is straigth from the manual:

• Connections

Connect the supplied power chord to mains plug (1) and then connect it to the mains supply.
Connect the interconnect cables to the RCA plugs at the rear. The sources are identified on the front and are in correspondance with the printing on the rear plate

(2). You can chose LINE 5 as unbalanced (U) and balanced (B) input with the small switch located between the inputs. A tape monitor output is available for recording

(3)Connect the speakers cables to the corresponding binding posts as referenced on the rear plate printing

(4)The impedance is automatically adapted to the speakers.

Hope this helps.

This amp is a hybrid with only one tube which goes in the preamp. The power section is solid state. Cheers, Josep
