What does check SP wires mean on Yamaha receiver?
If “CHECK SP WIRE” appears on the display, the speaker cables may be short-circuited. Make sure bare speaker wires are not touching each other or the back panel of the unit, then turn the unit on again. If “NG” is displayed, immediately unplug the power cord from the wall outlet and contact your dealer.
What does SP cable mean?
You have figured out that “check SP” means check speaker cables. You also state that even with the speakers on B unhooked it still goes into shutdown. Is that unhooking them at the receiver or the speakers.
What does OEM mean in speakers?
OEM stands for ‘original equipment manufacturer’.
How to check SP wires on Yamaha dsp620?
Go through every speaker making sure the connections are good. Check the cables and make sure your kid hasn’t stabbed a pair of scissors through the cable or something. If this is still all fine, then you have to do battle with the spaghetti monster and get to the back of the amp. Check all the cables there.
Why does my Yamaha receiver go into standby?
If the speakers are some distance away from your listening position then the receiver will obviously need to work harder to attain reference as measured from your listening position. If the receiver is having issues with the impedance or load imposed upon it then it would use its inbuilt protection circuitry to put itself into standby.
What should the impedance of a Yamaha receiver be?
I’d suggest setting the receiver to its default 8ohm setting irrespective of the impedance of the speakers. You are simply starving the speakers of power if you set the impedance switch to its lower setting and there’s no practical reason to set the receiver to the lower setting.
How many ohms does a Yamaha 600 Series Speaker have?
My speakers are all B&W of various guides (all 600 series, 605, 604, 603, 602 and 601) and they are all, with the exception of 605, circa 6 ohm resistance – which can obviously be different to impedance… but I expect they will be circa 6 ohms impedance at most frequencies too.
