Question about JVC RX-7000V Receiver

1 Answer

Because my rear speakers are popping and crackling during DTS output, I believe my settings of bass or treble might be overloading my speakers... should I set the rear speakers to "flat"? should I do that to all my speakers? will they still be discrete channels for DTS? What levels should I put for bass and treble if I were to put as "flat"? should i also turn off bassboost? I am kind of scared to hear those cracks and pops because they are loud, despite my volume to be either high or super low.... thanks again!!

Cracks and pops are dangerous. Can you tell if they might be circuit overloads or maybe digital decoding errors?

Are you routing bass to small speakers. THAT would definitely have audible problems. Define all of your speakers Large vs Small based on their bass-handling capacity.

ONLY DTS? Probably NOT the speakers or amps. How many sources are involved? Could be with the source or cabling.

Does it happen at low volumes, too? Then it would probably be digital in origin.

Do the indicators various digital surround mode indicators flicker or turn off when the pops appear?

As for the rest of your questions, I'd set everything at flat and start all over. If you're maxxing out any settings, something is wrong.

    Hi Dunnbiker!! Thanks for your feedback!!
    So far, it is only happening to the rear speakers, and it only happens during DTS/Dolby selection even at very low volumes, even with only at volume level 1 or 2... it doesn't happen with analog surround sound... so far i did set to all my speakers as "SMALL", and the wires weren't changed at all... before I used a pioneer that supports AC3 Dolby only, but not DTS... i am pretty sure the pops and cracks are not from the movie, since I also tried Hurt Locker and at the beginning, when there was explosion, i heard a pop even at volume level 1, so i turned off the volume right away!! wow, very nervous to even try out the sounds... i am only using an ASUS O-Play media player, and using optical cable to the receiver. When you mean setting everything at flat, does it mean putting the bass/treble all at 0 db?
    Please let me know... thank you once again!!

    Yes, set anything that boosts bass to nominal. You might be able to leave this part alone for now.

    So it would seem the decoding is the problem.

    You didn't answer these questions:

    Do the indicators various digital surround mode indicators flicker or turn off when the pops appear? (page 16)

    How many sources are involved? Could be with the source or cabling

    =======

    Selecting DTS manually instead of allowing the unit to automatically detect the format may be a problem. (Page 16)

    Take a look at the procedure starting on the upper right of Page 25.

Bass treble adjustments


I have the Toshiba Satellite C55-A5300.

I'm not sure about before the update, but after the windows 8.1 update my audio was pretty bad and had no bass at all.

In Control Panel ---> Hardware and Sound I found "Realtek HD Audio Manager" which has a tab named "DTS"

Once I hit the Launch buton I was able to apply settings for headphones and external speakers including bass boost.

My audio is now much better.

Hope this helps.

Most laptop sound card do not have a setting for bass and treble.
You can use external powered speakers that have bass and treble settings and connect these speakers to the headphone socket on your laptop.

I have set up a BOSE Accustimass System with my STR de485 receiver. How do I adjust the treble/bass?


hi,
if u are using bose speaker system then remember one thing. go to speaker setup and select all the speakers as large not small. then only u will get a good tone. bose speakers will handle the output power of ur amplifier.
u can only adjust the bass and treble of ur frond Channel speakers. for that
select multi channel surround sound and the increase and decrease the bass and treble
ok

Bass problems


At the audio mixer settings choose playback and look for something like "for advanced users" or like that. Here you will find the BASS - TREBLE control. In some older audio cards there isn't any selection like that.

Low treble


I suspect that the speaker levels need to be set. You connected everything right - many people would not have connected the sats via the bass section (which has their high pass crossover and overload protection). But I am betting the HSU is turned up a bit on the high side.

Try this. Set all speakers to small, set all levels to 0. Play the receiver in stereo all mode. If the bass is strong, you need to turn the HSU down closer to a natural sound. Then use the speaker setup tone and adjust as needed.

Logitech r-20 speakers


Hi again andrew63,

There are two possible methods of adjusting the bass and treble output to your Logitech R20 speakers:
1. Hardware - if you feel like experimenting or working with electronic gadgets, you can connect an external preamp with tone control or graphic equalizer between the PC and the input of the speakers/amp; and/or (probably the easiest)
2. Use a software (to listen to your music files/medium) that has a virtual equalizer such the old MusicMatch Jukebox or as an add-on/plug in.

Btw, thanks for asking me to be a Tech Buddy.
