sub problem w/ onkyo 805


Active Member
Got my 805 back today after its front display failed. Repair sheet shows all tested ok.

So I plugged all in and fine... apart from no sub output. (I dont get it because I'm familiar with the settings on the amp.).... AND im not getting the subs test tone either.

The sub does work. I tested it afterwoods on my old amp.
My Settings
hardware; coax cable plugged into subwoofer pre-out
(the purple output under the center pre-out.)

software; Speaker setup > speaker config > subwoofer: yes

Thanks for reading.
Where am I going wrong?

im gonna try the left and right pre-out channels for the sub since the sub has left and right inputs.

edit: pre-outs left and right for the sub works!

this is the email I sent to my supplier.
Hi C.A.

Receieved my [Onkyo 805] back today thank you.

I got one small problem though, I cant for the love of me get the sub-p.o. to work on my [Wharfedale Topaz sw-15.] The [sw-15] works fine. I've tested that on my other [amp] and though the left & right p.o. on my [805].

hardware config; sub-preout (purple p.o under center p.o) through coax cable to my [sw-15] input
software settings; setup > speaker setup > speaker settings > subwoofer = yes

Note(s): ~ I've changed sources, listened to 5.1 sources all to no avail. ~ NO TEST TONE for subwoofer. ~ After trying everything I know to get it to work I've done a FACTORY RESET that didnt work either.

Basically; I got it back > plugged all the inputs in > plugged it into mains > & no sub.

So Im thinking what can the problem be? If its not a software setting ive overlooked (possible?) Is it a dodgy p.o? But saying that It came back and tested ok. If it tested ok does that mean all p.o. are suppose to be ok. How can I test if the p.o.

legacy; p.o = pre-out
