    Thanks! Will try it right away

    If it ends up being the transistor?

    Would you have a circuit diagram for the preout board or where the transistor is located?

    Really appreciate it

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

Where should I plug in my sub woffer


There should be two jacks on the back that say SUBWOOFER in the "preout" section of the back panel that is directly above the speaker jacks. Either of these jacks should work for your sub hook-up. Also make sure that you set your front speakers to small in the speaker setup menu, otherwise there will be output to the subwoofer jacks.

Preout section cannot ingage


If you are using a pre out to a sub woofer, you need to make sure that the sub has it's own power amp or it will not work. You also need to go into the user menu and tell the amp that you are using a powered sub. Otherwise it will not turn on the pre amp output

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...


hi,
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.
ok

Cant get bass, fuse is fine


You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.

Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.

Sub woofer


Is there a gain control on the sub? If not, are you using a receiver or pre/processor to control volume? There could be a level adjust or on/off control for the subwoofer output.

Sub Woofer Won't Work


Connect the input from the powered subwoofer to the rca jack on the VSX-409D labelled 'sub woofer preout'.
