8 ohm or 4 Iohm

[jamoman]

<font color='#000000'>I have a Yamaha RX-Z1 receiver and a Yamaha MX-1 amp to drive my main speakers that are rated at 4 ohms. Should I set the impedance selector to 4 or 8 ohms? My  speakers are  Jamo D870 main, D8 center, and D8 surrounds. I currently have the switch set at 8 ohms will this damage my receiver or my speakers?

<font color='#0000FF'>Keep the settings to 8 ohms for your RX-Z1 and as far as the MX-1 amp goes it has no impedance selector switch and can drive speakers all the way down to 1 ohms. I am using almost the same setup as yours except that I have the DSP-AZ1 and MX-1 as main with Yamaha speakers for front and rear which are rated at 6 ohms nominal.

The impedance selector is for UL certification purposes as traditionaly Yamaha recievers and DSP amps have had the capability to drive all the way down to 2 ohms. This is also explained quite clearly in the Audioholics site with technical description.

Btw: Where did you buy the MX-1? It has been discontinued by Yamaha since last year.</font>

<font color='#000000'>Thanks for your advice on the RX-V1. I will read that article that you mentioned. I bought the MX-1 about 2 years ago at LaSalle Electronics when they used to have a store located here in Macomb, Illinois. I also made a mistake when I posted yesterday, I have the RX-V1 not the RX-Z1. I was thinking about buying the Z-1 but I think I will hold off on that purchase for a while!
