questions on vtf 3.3

[tractng]

Guys,

I got the sub yesterday (late last night). My first HT:p


I noticed that on the "auto" for power, the sub turns off even if the movie is playing. I read the troubleshooting guide, but not sure what is the right way to fix it.

I am using the Onkyo 604. Is there a setting for adjusting sensor?


Also, what frequency is recommended? I read 90, but what are you people sitting at?

What is volume of the "subwoofer" level on your receiver set at? If this is too low it won't send enough signal to the sub causing it to go to sleep. Also the auto feature causes the sub to turn off if it doesn't get a signal for 5 mins.

As for the frequency to set your crossover at that depends on the extension of your speakers. What's the frequency response of your speakers?

Iradden,

I did set my volume too low (it was late at night). Once I cranked up the volume, my sub started to play.

I am running at 120 on my small speakers. My receiver can only be dialed to 80 the lowest on the sub.

What receiver brand and model do you have? What is the frequency response of your speakers? Also the subs amp probably won't need to be set more than 25% on the sub's gain control.

Not talking about your receiver volume level, he's talking about the indivudial speaker input levels in settings menu. You can raise the input level on the subwoofer slightly to give a stronger signal to wake it up. You would need to lower the gain on the sub according to how high you go on the receiver. Too high on either one is not good though.

Thanks Bill that's what I was trying to say, but not as well as you did.

Guys,

I have an Onkyo 604. I set the speakers to +7db out of 12.

Here is the info on the speakers:

Tweeter:1 (.95 Piston Diameter) soft-dome, ferro-fluid cooledMid-woofer:4" (3.5 Piston Diameter) long throwFrequency Response:90Hz - 22 kHz +/-2 dBPower Ratings:25 watts min/150 watts maxSensitivity:88 dB (2.83V @ 1 meter)

On a side note, if my receiver only goes down to 80 on the lfe, I will need to use the crossover of the HSU sub instead if i want it lower? Just making sure since i am a newbie here.:p

Btw, I have the sub volume dialed to about 10 a.m.

OK so your speakers extend down to 90Hz, so I'd play with 80Hz since any higher and the sub will be localized and you'll be able to tell where it is. Any lower than 80Hz and you'll have a huge gap where your speakers cross over to the sub. You can even try 100Hz, but it might localize the sub.

On a side note, if my receiver only goes down to 80 on the lfe, I will need to use the crossover of the HSU sub instead if i want it lower? Just making sure since i am a newbie here.:p Yes you are correct, but with speakers that only extend down to 90Hz you definately don't want the sub lower than 80Hz. You want a smooth transition from the speakers to the sub and lowering the crossover too much below 90Hz will create a gap. Use the receiver's crossover at 80Hz or 100Hz.

Btw, I have the sub volume dialed to about 10 a.m.What are the dimensions of your room? 10:00 on the sub dial is about the highest you should go. The BASH amps on the Hsu subs are VERY powerfull and may distort if run at 12:00 or higher.

What have you used to calibrate the sub and your other speakers? Does the 604 have a auto speaker setup feature or are you using a Radio Shack SPL meter and using the receiver's test tones to calibrate?

Also feel free to ask all the questions you like we're here to help.

Iradden,

A lot of guys on the avs forum are running the cht front speakers at 100 hz. I guess I will run at 100 and the sub at 80hz.

The room is about 12x23 with 8 feet ceiling.


I have not had a chance to calibrate my system yet. The receiver has an auto speaker setup.

Is running +7db out of 12 on the sub too high?

Thanks,
tony

Sounds a little high to me. Most people try to set it up where their receiver input is at around -2 to -4 so they have to play area if they want to turn it up or down. I would try to set your receiver input to no more than +3 and just go up a little bit on your sub to around 12 o'clock, if your at 10 now. Also, auto setup doesn't always work properly, especially with sub.

Thanks a lot.

Yes +7 is high do like Bill said and raise the sub and lower the receiver.

A lot of guys on the avs forum are running the cht front speakers at 100 hz. I guess I will run at 100 and the sub at 80hz.How are you going to run at 100 and the sub at 80Hz? You should be using only one crossover either from the receiver or the sub not both.

I meant from the receiver, i have setting the speakers to 100hz and the sub at 80hz.

OK I understand now your 604 has setting for multiple crossovers for each speaker and a seperate crossover for LFE only. So your speakers will crossover at 100Hz and LFE will be crossed at 80Hz.
I didn't know the 604 had multi crossovers and a LFE crossover. I thought it had just one crossover and you we're using the sub and the receiver's crossover at the same time.

Good thing I read the manual.
