Trouble connecting sub to my A/V amp - AVS Forum

I have a fiarly old Pioneer VSA-E07 amp and was wondering how I would connect my Sony subwoofer to it. The sony subwoofer runs on a coaxial cable, but I don't think I can use this on my amp.

Heres the connections for the amp;



Any ideas and advice on what type of sub I could run off this amp would be highly appreciated smile.gif

*Same thread posted in A/V amp section

Use the subwoofer pre-out (sw) in the upper left area of the avr.

I've tried that it seems thats a RCA connection and the sub uses coaxial cable. Any more suggestions? Thanks

Yes: Post a pic of the sub's plate amp.

Here it is;



I've tried connecting it to the preout subwoofer connections with no luck, using a coaxial cable. Maybe I have the change some settings on the amp?

I was using this sub in my older Sony setup with a coaxial cable into the sony reciever, a picture of that'

Both connections look standard to me. Do you have your speakers set to "small" in the AVR?

I'm new to the amp so I'm not sure! Trying to check that now but can't find a setting like that!

Maybe I shouldn't be using a coaxial cable for this amp?

I've seen it happen before where someone has accidentally connected the cable to the pre-input terminal (circled in red) rather than the pre-output terminal (circled in green). So, just to confirm, you do have the cable connected to the pre-output terminal?

If 'yes', have you tried another cable just to make sure there's not a problem with the one you're using?

If it's got RCA connectors on both ends, that's what you should be using.

Coaxial refers to the construction of the wire, not the connectors used.

+1.

Yeh I tried both of them just to be safe, but not with any luck. The cable did work when I was using it for my other amp so I'm 90% sure it is, however will double check that.

It does have RCA to RCA connection but has "digital" written on the connectors, which made me think it was a coaxial digital cable. Might order another RCA to RCA to see if that might work?

That's meaningless advertising piffle. Wire is wire. Insert the cable into the sub amp, turn it on, put your finger on the center conductor at the other end of the cable. The sub should hum. If it doesn't the cable may be bad. If it does the cable is good and the problem lies either in the AVR or in how you have it hooked up.

It is, in the sense that it's not an optical digital cable. But coaxial digital is a cooler-sounding way of saying "wire with RCA connectors on both ends".

Save some time and money by using that cable for a left or right analogue connection from a source (DVD or BD player) to the AVR. If you get audio through the channel that cable is on, then the cable's fine.

Thanks everyone, and especially the RTFM advice! biggrin.gif

Turns out the front speakers had to be turned into small ones as bfreedma suggested. Sounding great!

Huh? I was under the impression it typically was the man way to dive in without RTFM.

Sure, but now not only did he RTFM, he set his speakers to small smile.gif
