I am the owner of a Al-3 plus since 1998 and 3 months age I change my power amp to a Rogue m-120 monoblocks ( http://www.rogueaudio.com/Products_m120.htm ) which has separate 4 and 8 ohm speaker taps in the back, and for whatever reason ( I must be daydreaming) I connect the al-3 to the 8 ohm speaker taps 3 months ago and use it 2 to 3 hours per day. My Question is (a) Is the al-3 is Impedance at 4 Ohms? and (b) Will it cause damage to the amplifier or the speaker if I use the incorrect ohms taps?
Today, I moved the speaker cable back to the 4 ohm taps, and I hope I didn't damage anything.
