Pre-out for sub in-op

Can't get anything from my pre-out for my sub. Sub is toggles "on" in speaker set-up. Any other tricks, or could the pre-out be bad?

Re: Pre-out for sub in-op

First make sure the actual sub is powered on .You can tap on the RCA leading to the sub and hear the sub humming..Im assuming you do have a powered sub connected to sub out of receiver .Also you could also connect another type of speaker with RCA to make sure if it has output or not..Also make setup does have sub output ON..thanks

I have a active sub woofer (akari bazooka) but the only connections available are the speaker connections. The front of the sub woofer has volume adjustment. How can I connect this sub woofer to my Harman...

You can't connect the pre out of your AVR to this sub woofer. Do one thing connect the frond left/ right channel speaker "B" out of harman kardon to the sub woofers left right speaker in put. you can connect the speaker out "A" to your normal left right speakers. Remember to switch Speaker "A" and "B" in ON position in your AVR. Also do one thing go to the speaker setup of AVR and switch OFF (slelect NONE) the sub woofer.This will disconnect the sub woofer pre our and the sub frequency will mix with frond left right channels.

Do you mean sub woofer. Then you can select any brands Active sub woofer ( active means built in amplifier) to connect with your system. They comes in different power (watts). you can use an active sub woofer with 100W output.
connect the sub woofer pre out of you amp to the pre input of sub woofer.

You need to use an amplified sub. The Yamaha receiver is only sending "Pre-Amp Signal" not amplified audio like the rest of your speakers. If your sub has a crossover built in, connect it's speaker level (wires) to the "B" side of the receiver which will send audio to your sub and it will cross it over internally. Not the best sounding, but it works. Amplified subs range in price from 200 and up. Hope this helps

How to hook up my subwoofer

It sounds like you're doing everything right. Did you define the sub to the Onkyo (Subwoofer = Yes, page 22)?

Let's prove the sub works. Set its volume about half-way, cutoff= 170Hz. Temporarily connect an RCA cable from its Line Input to one of the Tape Out connectors on the Onkyo and play some FM through it. If it's alive you'll hear the low end of the music.

Don't buy into the hype that there are different pedigrees of RCA (or speaker) cables that will make an audible difference. Save your money.

Kenwood 107VR rec and No vol from Sub Output w/ menu Opt On

In the setup menu are the speakers set to large or small? On some receivers if you have it set to large all the bass is directed to the right-left fronts.
On my pioneer receiver if the speakers are set to large the sub-pre-out only works if the receiver is in a surround mode, if its in stereo mode and the speakers are set to large the sub-pre-out is dead. If the speakers are set to small the sub-pre-out works all the time.
Also, some receivers won't send a signal to the sub-pre-out if there is no LFE discreet signal info from the dolby digital or dts bitstreem.
For example I have several older dvd's that light up the L C R SL SR icons on my receiver, but don't light up the LFE icon. I have other older dvd's that just light up the L and R icons meaning they are only recorded in stereo like a vhs tape recorded in dolby surround.
In my basement I also have a kenwood dolby digital receiver.
I've noticed that when a dvd only lights up the left and right icons the pioneer will automatically switch to dolby pro logic surround. The kenwood will only send the signal to the left and right fronts (stereo). If I manually switch it (kenwood) to dolby pro logic I'll get sound from all the speakers just like the pioneer, but it does'nt do it by itself.
Most receivers that have a tape monitor won't work in surround mode with the tape monitor on. The pioneer will let me use the tape monitor with dolby pro-logic but won't pass through a dolby digital signal with the monitor on.
Hope this helps.

Sub Woofer works but it won't when hooked up to the receiver

Yes, go to your menu then setup then speakers then subwoofer, it's probably in "LFE" it should give you the option of Sub, LFE, or Both. that should do the trick. Also check the crossover point and season to taste. While your at it; there should also be a setting for speaker level, toggle down to sub and adjust the sub out level, it's probably at it's minimum setting. Hope this helps

No Sub Woofer Pre out output

I've got the same model and the pre out transistor needs to be replaced,
sometimes you can get it to work by unplugging the reciever and the pre out
then plug in the reciever and plug the pre out in a couple of times or so untill it comes on
or unplug the amp from the wall then plug in the pre out , turn on the reciever wait for sounds to come on then plug in the amp.
if that don't do it the pre out transistor needs to be replaced
