RX-V620 into 4 ohms (1 Viewer)

[ChristopherD]

Can the Yamaha RX-V620 drive a 4 ohm load? I've checked the manual, but can't seem to find this info. I'd like to mate it with GR Research A/V-2's.

Check the specifications in the back of the manual. It will tell you the power rating and at what ohms.

That said, it is generally not a good idea to run 4-ohm speakers with an A/V receiver.

Christopher;

The Yamaha RX-V 620 will drive 4 ohm loads. Problem is some 4 ohm speakers dip into 2-3 ohms at certain frequencies, but that is a story for another day.

You will find an 8 ohm - 4 ohm switch on the back of the receiver. I tried this (only move switch with the unit OFF) on my DSP-A1 to drive my 4 ohm speakers and it actually degraded the dynamic range, so I switched back to the 8 ohm setting where it sounds best.

Happy listening!

Thank you for your responses. Interesting point re: the switch and what sounds best.
