Integra DTR-5.5 sub out signal low or no sound at all?

[chris89]

Hi my Integra DTR-5.5 has a problem where the subwoofer out audio signal/volume usually doesn't work at all or the sound is so quiet it can barely be heard from a Monoprice 12" subwoofer. The subwoofer has been tested plugged into the receivers DC outlets & plugged directly into the wall with no difference.

The receiver gets plenty loud through the Dayton Audio B652s as the two main stereo speakers. Its just the subwoofer that doesn't get the proper bass volume it needs from the sub pre out signal from the receiver.

Would an inline RCA bass booster volume adjuster help boost the bass volume signal from the receiver?

I reset the receive by holding VIDEO 1 & the power button for a couple seconds just to see if it helps & it doesn't. I even turned up the signal to +12db max on the subwoofer to no help. Any advice?

Thanks

Update : Learned a lot about this audio stuff by reading the Integra DTR-5.5 manual lol

So it says it won't make any sound if the source doesn't send a sound to the LFE channel.

We use an MP3 player hooked up to say the front of the receivers Video 4 input audio RCA jacks to a 3.5mm cable primarily. The MP3 player just outputs STEREO signals, not 5.1 (with the .1 being the LFE channel). We have a 2.1 system, which is two Dayton Audio B652s 6.5" speakers & a 12" Monoprice 150W RMS subwoofer. This is quite interesting that it requires the LFE signal.



The subwoofer produces no sound?

​

• When you play source material that contains no infor-

​

mation in the LFE channel, the subwoofer produces

​

no sound.

​

• Make sure the speakers are configured correctly

My friend instead of using the sub pre out, he uses like Video 2 out & just gets a bass signal that way because its louder than the sub pre out.

We tested a Dolby Digital 5.1 movie & the bass was nice from the SUB PRE OUT, but no bass comes out when listening to Music over any input. For the Dolby Digital 5.1 we used Digital Optical over the front VIDEO 4 input.

Any advice would be highly appreciated.

Seems you might need to spend more time RTFM

You should be able to use the sub with 2.0 sources in a few sound modes. What sound modes are you using?

Did you run the avr's automatic speaker setup? Or did it manually? Do you have speakers set to large/full range? Or small with crossovers?

What sub specifically is it?

 

[chris89]

Yeah I read it sufficiently now.

This is the subwoofer Monoprice 12in 150-Watt Powered Subwoofer, Black - Monoprice.com

Also I set it all up manually set the fronts to large & increased the volume by 12db & set the double bass to on & set the crossover to 150hz because in the manual it said the subwoofer may not make much noise if the crossover is set too low which is obvious.

I only use 1 sound mode & its just plain STEREO mode. Unless its hooked up to the XBOX ONE over digital optical which is set to DTS in the XBOX ONE settings & its working as DTS on on the receiver.

 

[lovinthehd]

LOL sorry, couldn't resist the rtfm thing

Don't know if stereo mode uses the sub on your unit if speakers are set to large....what did the manual say about that? What happens if you set the speakers to small? A xover of 150hz seems high for those speakers, I'd start with 80. Where do you have the gain on the sub set? You have the subwoofer trim level maxed out at +12dB? That seems excessive.

Subwoofers may not be as actively involved as you imagine, too.

ps By manual you mean you used an spl meter to match levels or winged it by ear?

 

[chris89]

Yeah 12db in the receiver settings but the crossover is set to 80hz & volume knob to 25%-50.

I can't find anything about the modes not working on the subwoofer but ill test it now. I'll test 80hz crossover in the receiver settings as well.

What page are those quotes from?

As to the relationship of the sub trim in the avr vs the gain/volume on the sub, it seems you might need to raise the gain/volume on the sub so you don't need to max it out on the avr....I prefer to keep sub trim level below 0 myself. Subs in general with much music do not get a lot of work....

Update : I tested all modes & set crossover to 80hz. The subwoofer only seems to work over digital signals like DTS or Dolby Digital, not analog inputs. We use VIDEO 4 input on the front of the receiver for an MP3 player RCA to 3.5mm STEREO or VIDEO 4 Digital Optical input to an XBOX ONE console.

Okay so should I set the gain on the receiver for the subwoofer to 0db or even lower than 0db?

In the setup menu of the receiver the sub should make a buzzing sound to verify its working when adjusting the gain volume of individual speakers, but there is no sound coming from the subwoofer at all.

**We tested GODZILLA Dolby Digital 5.1 & the subwoofer sounded pretty good using the subwoofer PRE OUT but didn't make any sound when listening with a music player over DIGITAL OPTICAL VIDEO 4 Input from the XBOX ONE Console.**

Will look thru the manual to see what I can find.

BTW I wouldn't use the AC outlet on the back of the avr for an amp or sub amp....just something requiring low power like an optical disc player or similar.

 

[chris89]

Thank you. Yeah my friend tested it plugged into the wall & into the receiver & he said it made no difference. I recommended him plug it into the wall directly but were honestly limited on power outlets here where I stay. They don't let us use power strips or extension cords or anything of that sort. All we have is 4 outlets on a wall.

I appreciate it bro.

Pg 60 of the pdf manual indicates the stereo mode would include use of the subwoofer, but not in pure/direct modes.

It's not a quality thing, it's a capacity thing....look at the spec right near the outlets on the back of the avr. Use something else for subs and amps.

The one weird thing is VIDEO 2 OUT lets the subwoofer beat, but needs the built in amp crossover on the subwoofer to filter out the highs (not ideal at all). Its the volume though, this allows the bass to hit on all inputs.

Yeah it says 120 watts max. Which would make perfect sense not to plug it in there. Thanks

 

[lovinthehd]

I started more about the use of the sub but got distracted by the outlet thing . Stereo mode seems to be enabled for the sub (some makes/models of avr that's not necessarily true). It's not useful in a direct/pure direct mode, which would be a way for someone not to use the sub. It's possible with an old used unit something isn't working correctly.....did you start with a complete reset of the unit (assuming there is one)?

Video 2 out would bypass any bass management in the avr (but not sure just what that is so far either). Video 2 would likely also be a fixed output without volume control. Not sure what you particularly mean about "allows the bass to hit on all inputs".

As often the case, the manual is vague on some points. I did ascertain that you will get no subwoofer output from analog connections in straight stereo mode.

However, I think you will if you use the mode button, which is button 11 and select Dolby pro logic 2.

However, the manual is vague on one point. It does say that it will not convert analog signals to digital and vice versa, at the record outs. In other words if the source is analog then you won't get a digital record out. If the source is digital, then you won't get an analog record out. This suggests to me that this old receiver does not do conversions at all. Since processing takes place in the digital domain, you might only get a subwoofer output, if the source is optical. or digital coax.

So play a two channel source via RCA input, and set your mode to Dolby Pro logic II. If you don't get a sub output, then you won't from that source. I have established that won't get the sub to work on selecting stereo with the crossover. However, here it is vague again, you might if you set your speakers to large and select double bass in the speaker set up menu. The speakers and sub will then be outputting frequencies below where you set the crossover.

Basically you need a more modern receiver, that one is well passed its sell by date.

 

[lovinthehd]

Manual does seem to simply not discuss key aspects of input/bass mangement options.....but its an old avr and personally would just get a newer one.

 

[chris89]

Thanks for the replies. Yeah we tested the bass on a Suca Audio M-98E PRO & Dayton Audio DTA PRO & both had solid bass from the SUB PRE OUT.

Okay yeah I just thought there had to be some way to get it working properly over the SUBWOOFER PRE OUT jack on the receiver.

I tested all the modes & none of them gave any bass over the SUBWOOFER PRE OUT using the RCA Input on VIDEO 4 on the front of the receiver. Also what I meant by VIDEO 2 OUT allows the bass to hit while using any input source basically it mimics the inputs of all sources & outputs the same signal with highs & lows. So my friend plugged it in to the subwoofer & it works. He basically went through every plug trying each one until he got sound from the subwoofer & found VIDEO 2 out RCAs gave sound.

**I'll fiddle with it some more & select Dolby Pro Logic II & see what happens. We use an RCA splitter to single RCA jack since the subwoofer has WHITE/RED input/outputs.**

 

[chris89]

Update : I tested Dolby Pro Logic II Movie & I think theres a Music mode too & sure there was a little bass, but had to turn up the subwoofer almost all the way up to barely hear it.

VIDEO 2 out here though is much louder but its not a low pass output, it outputs highs & lows so the subwoofers crossover does all the work to keep it all lows. Its not ideal but it gives the most bass over the Subwoofer Pre Out. I think we need a new receiver for sure.

We also tested the SUBWOOFER PRE OUT on the Dayton Audio DTA PRO & it sounded fine but the subwoofer quality is lacking. Too much port distortion & port noise bouncing off the bottom of the box.

This below picture is VIDEO 2 OUT right? It seems to output sound from any input, that would make sense right? I'm not used to using OUTPUTS, just INPUTS. If we use VIDEO 1 or VIDEO 4 INPUT, VIDEO 2 OUTPUT mimics the sounds from those inputs. This probably makes perfect sense huh?
