Question about speaker set-up and sub setting for 74txvi

[jfabes]

when i set my towers to 'large' and sub to 'yes', i don't get any sound from the sub. this is how the mcacc set the system up.

if i change the sub setting to 'plus', with the fronts set to 'large', the sub works fine.

is there some kind of default override that when the fronts are set to 'large' the sub will not work on 'yes', but only on 'plus'

any help is appreciated

This is from the Audioholics set-up tips on the homepage:
Receiver setup:



Bass management: Large/Small speaker settings. Set all speakers to small, let your subwoofer handle the low frequencies. Find a comfortable crossover setting, it might not always be THX’s recommended 80Hz.
LFE: Enable LFE (low frequency effects) to drive your sub. Your receiver might have an on/off setting for stereo.
Dynamic Range: Set to 100% (night mode, dynamic compression turned off).
DSP modes: Turn off all DSP modes. Only experiment with these when you’re ready to play with the sound.
Dolby Pro Logic II or IIx: Dolby PL II and IIx are primarily used for two channel (stereo) sources and PL IIx can also be used for discrete 5.1 sources to expand them to 7.1. Double check to see if the PL II or IIx settings are saved for each input selected. IE: Setup “music” appropriately for CD input, switch to VCR and see if your CD settings carried over to the other inputs. PLII presets and saved settings per input are convenient features and often overlooked when shopping for an A/V receiver.
Dolby Digital/DTS: Enable automatic detection of Dolby Digital/DTS for digital audio inputs. This should override any Pro Logic II or DSP setting you have chosen. There should be an indicator on your receiver’s front panel to let you know which audio format is detected.




DVD Player setup:



Bass Management: Large/Small speaker settings. Only one component should handle bass management. Receiver, DVD player or another specialty component such Outlaw’s ICBM. If another component is handling bass management set all speakers to large or turn off bass management.
S/PDIF: Use your DVD player’s digital audio output only (coax or optical). Do not use the RCA stereo output if you already have the digital output connected to the receiver.
Bitstream/PCM: Set audio output to bitstream. The only reason you wouldn’t want to use bitstream is if you’re not using the DVD player’s digital audio outputs. Almost all DVD players have PCM set as default, PCM will not send Dolby Digital or DTS to the receiver even if the DVD player is compatible with those audio formats. Countless new DVD player owners will listen to stereo PCM transmitted to their receiver over digital outputs, wondering why the receiver isn’t detecting Dolby Digital or DTS.
Audio filtering or effects: Disable any audio noise reduction, filtering, DSPs or any other audio effects your DVD Player might provide. The A/V Receiver can handle these. Experiment with these settings later, after you’ve heard the “true” sound of your system.
Aspect Ratio: Enable widescreen mode (16:9) assuming you have a compatible display for this aspect ratio. Disable zoom. Depending on your viewing preferences, zoom/stretch modes may be used on 16:9 displays when watching 4:3 program source material to utilize more screen area. There should be an independent setting on your display to enable these modes when viewing 4:3 program material.
Video output: Always use the best possible video output available on your TV. If your TV is High Definition you MUST use either Component outputs (R,G,B) or digital video such as DVI or HDMI to get a de-interlaced video signal to your TV. S-Video is your best option for non-digital TV.
Progressive Scan: Enable progressive scan if your DVD Player has this feature and your TV is Digital or HD.
Other Video Features: Black level, brightness, filtering etc should all be initially disabled on the DVD Player. In most cases all of the video tweaking should be done on your display. However, if you cannot achieve an accurate picture, you should then look at tweaking using the DVD player video adjustments.

If the mcacc is an auto set-up feature, set all speakers to small, sub to yes, and set the receiver to skip the speaker size feature in the set-up. If you can't, just go back and set them to small.

I tried to look at your manual, but Pioneer wants me to register. Bummer.

Here's the manual:

[zumbo]

Page 33 in the manual states to choose YES for the THX option to set all speakers to small. It looks like this is how to accomplish this with your receiver.

Thanks for the link Buckeyefan!

when you set your towers to 'large' and sub to 'yes/plus' all the bas is referin to the sub and your front, your sub need to work if it is not working samething is wrong with your amp, now try to set your front to small and the sub to yes with this seting all the bas is referin to the sub this is recommended setup.

Most auto-setup routines seem to set the fronts to Large. All channels set to Small and Sub=yes (with an appropriate xover frequency) is generally a better setup.

However, the receiver is behaving properly by not sending any bass to the sub when the fronts are set to Large - that is the definition of Large - the speakers get a full range signal and nothing is sent to the sub. If you want to keep the fronts at Large AND have the sub play the bass for those channels, then you need to set it to Plus. With the Plus setting, the bass from the front channels will ALSO go to the sub. If you have a Yamaha, the same setting is called LFE+MAIN. If you have an Onkyo, the same setting is called Double Bass. All the receiver manufacturers copy each other, but name their particular implementation of the same feature differently.
