No sound from subwoofer

[jlyttle]

I just got my new HSU VTF-2 MK 3, but cannot get any sound from it. It does turn on , the power light is green. I am using a subwoofer cable that I ordered from BlueJeans cables, and have the setting Subwoofer: YES set on my Onkyo TX-SR604. All other speakers are working. Any ideas?

What type of source material are you trying to play?

Did you try the test tones? Does it work when you play those?

 

[Seth=L]

Have you already had a sub, other than the HSU, connected to the Receiver before?

 

[jlyttle]

No , new setup, never had a sub before.

I was just trying to play one of Comcast's music channels, did not try a CD.

I would be checking the settings to the receiver. The factory presets in Onkyo's receivers is LFE only, so unless you are whatching a DVD with a discrete .1 (LFE channel) it will not send a signal to the sub. You have to activate Double Bass or Dual Mono on the receiver in the settings. Refer to your user manual for a detailed guide to do so.

Good luck.

LFE is set to 120, and DoubleBass is set to ON. Is this all that I need to do or should I look at other settings?

What speakers are you using? 120 is a little high for the x-over unless you are using satelites. If you are using full size speakers I would set it to 90hz or lower. THX standard is 80hz.

 

[jlyttle]

Wow you guys are fast.

My understanding is that when using the subwoofer cable that crossover is off? Also, I don't know what LFE is or what the settings should be. I am a total novice.

Speakers are:

Axiom M3 v2's - Fronts
Axiom VP100 v2- Center
Polk RC60i - rear surrounds
Sub- HSU VTF-2 MK 3

LFE stands for Low Frequency Effects, it is the .1 in 5.1 surround. It is a channel that contains nothing but low frequency bass signals. Doublebass is a feature on the receiver that allows it to derive the lower frequencies that your front speakers cannot play so they can be sent to a very capable subwoofer such as the HSU you have. Setting the x-over or cross-over on the receiver to a certain frequency reduces the demands on the receiver's amplifiers and sends the difficult lower frequencies to the sub. If the speakers are playing lower frequencies and the sub is playing the same frequency you could get cancelations that will introduce nulls in the bass. Setting the speakers to "small" in the settings and setting the x-over to 80hz it will send everything below 80hz to the sub (set the subs x-over all the way clockways to overide the internal x-over as it is not needed) and the frequencies higher than 80hz are sent to the front speakers.

Any other questions?

 

[jlyttle]

Well, the sub still has no sound........

Make sure you have the cable in the right sub out, the Onkyo has one for multichannel and LFE. The Hsu also has a bypass switch, make sure it is in the out position

Have you tried this yet?

Does it work when you send the test tones through the speakers?

I just wanted to clarify receiver settings a bit because there are a lot of settings.

- There is a difference between the xover and the LFE setting. The xover should be set to around 80 Hz as mentioned. The LFE (on the menu it says 'LPFofLFE' - low pass filter of LFE) can be left at 120 Hz.

- You do want to set Yes for every speaker that exists and set them all to Small. The Double Bass function will only work if you set the front speakers to Large and Subwoofer=Yes and that is 'double bass' because it will send the bass for the front channels to the front speakers AND the subwoofer. Don't bother with Double Bass until you get the subwoofer to work.

- Make sure the sub cable is connected to the jacks on the back marked 'Pre-out subwoofer' NOT the subwoofer jack in the DVD input section.

 

[jlyttle]

OK, the cable is/was connected properly. The model sub has a standby mode, that allows it to automatically turn on when it gets a signal. When I play something it does come out of standby. And yes, I did check the volume knob.

 

[Wid]

As was asked earlier, did you try the receivers test tones?

 

[jlyttle]

Not sure. Is there a specific place to try these? I did enter setup menu 4, which was to adjust DB, when changing to each speaker there was a white-noise coming from the selected speaker. This happened with all speakers but the sub, which was silent.

 

[Wid]

On the remote there is a button for the test tones. The sub should respond when doing this. Also make sure of the setting for the sub, on the receiver, put it to the + side for now. Where do you have the gain (volume) set on the subs control?

Yeah the test tones play through all but the sub. The Volume on the sub is set halfway.

 

[Wid]

There are two connections for the sub, are you positive it is in the sub "pre out" and not the sub connection that is in the dvd section.

 

[markw]

Two possibilities. (or three.. what WID said.)

1) The sub ain't working. check this out by plugging an analog source (CD, tuner, DVD, etc..) into the sub's input. If you hear muffled sounds vaguely resembling what you're playing, you know the sub works.

Now, try that again, but this time with the sub cable you're using. If it worked before and now doesn't, the cable is bad. If you get the same results as in he first test, you know THAT'S good also.

If the sub is working and the cable is good, the problem lies in the receiver. There's not much more I can offer there that others' haven't, aside from becoming very familiar with your manuals and perhaps invoking your receiver manufacturer's customer support for guidance..
