    I just got my Pioneer DV-45A yesterday and everythings sounds fine with DVD Audio and SACD except that I can't seem to control the sub level in the player. I am using the test tones from Sound & Vision's HT Tuneup disc and the sub level on my sound meter reads the same no matter where I set the level in the player. I am using the 80Hz crossover in my Outlaw 950 preamp for the 5.1 input. Thanks for any help.

    You can try this: Make sure that you have hit the 6 ch bypass button on the Outlaw's remote to make sure you're not actually listening to the DD digital feed.

    Another thing to check, is try to engage the actual sub test tone on the 45a, and see (hear! [​IMG] ) what happens when you change the level in the player. Just be aware that the 45a's sub test tone will probably not sound loud enough.

    Thanks Kevin,
    The 6 channel direct is engaged for sure but I have not used any of the test tones in the player itself, just the ones on my calibration disc. I'll try what you suggested. Thanks again.

    Kevin,
    I tried to engage the test tone for the sub in the 45A but you can't do that. It only puts out test tones for the other speakers. I am going to see if I can adjust the levels for the other speakers using the players adjustments. My sub level is just too high when playing DVD Audio or SACDs.

    Thanks for tip about the sub level test tone. I will try that and see if it activates the tone and the abillity to adjust the level.

    Brian,
    Thanks for the additional information. I'm not really that concerned about the accuracy of the tone. I just want to be able to turn down the level of the sub when using the analog outs. So far, adjusting the sub level in the player is having no effect on the sub. I also read the review in S&V but so far I have had no problem with overall output. It is plenty loud for me when using 5.1 analog material. When I get home tonight I will see what I can do. Thanks.

    I set the levels to "fixed" and then I adjust the subwoofer volume on the back of the subwoofer. I use the 6 channel analog for everything. So 2 controls to change depending on the disc; volume level on the receiver and volume level on the back of the subwoofer.

    One more potentially dumb question Matt...

    You have the player set to all speakers large/sub on, correct? That would be the way to go using the 950 as your crossover.

    FWIW, I have noted that my player has twice of its on accord changed settings on me. The first was when it switched from Fixed to Variable output (I noticed that I had to crank the volume higher than normal), and the second, it switched from having 5.1 outputs enable to just having the 2ch outputs on.

    Very weird. I think I may have read another user account of something similar.

    My point bringing that up? It won't hurt to make sure your player has remembered your speaker settings.

    Brian,
    My speakers are definitely set on large and sub on in the player. I will also double check the 5.1 setting and the fixed/variable. I'll see what happens tonight. Thanks.

    Brian,
    I agree with your last post about the large spk/sub on setting. This has to the correct way to the use the fixed 80Hz BM of the 950 when playing material from the 5.1 analog outputs of the 45A.

    Unfortunately, that's the wrong thing to do for the DV-45a *if* you are using DVD-A or SACD as a source. For these sources, setting the mains to LARGE eliminates sub output, period, even if the source is 5.1, even if the sub is set to ON. I can see that being an annoyance for those with large speakers . ;>

    Wrong Answer:
    When just using the 45a (ie - no ICBM) when you set the mains to large the bass in the subwoofer still represents anything that was specifically mixed the the subwoofer channel plus any bass from any of the other speakers that are still set to small. I run my gear most of the time with all speakers set to large and I still have subwoofer output as long as the disc was originally mixed with output to the subwoofer. When I play that SACD Surround of Bach's Organ Works By E Power Biggs the 25 hz pedal notes are very much in the subwoofer (as well as in the other speakers). If you really want to test out your bass pick up that disc.

    Question,

    I am thinking about a 45 or 47ai (trying to justiry the $1000 for the 47ai or a Denon 2500). Seems like you guys should know the difference between the 45 and the 47 beside the special digital ourput which I would not use, what is the difference?

    Thanks,
    Michael

    The 47AI would make sense if you mate it with the flagship Elite receiver[digital link],if you not planning to get,or not already owned[receiver] then it would be harder to justify the price difference IMO.
    I think KCB owned both,I'm sure he'll chime in.

    I double checked my DV-45a results, and, damn me, I'd misread them. Actually they are more consistent than I thought. I have corrected the original test post, and am reposting the three summary findings here as well:

    I) turning OFF the sub in the speaker installation menu always eliminates sub output from the 45a sub jack.

    II) if mains are set to LARGE, there is no sub output *unless* the source has a .1 channel (AND/OR you have set other speakers to small, as per Guy's correction, though I haven't tested that)

    III) if mains are set to SMALL, stereo (2.0), 3/2 (5.0), and 3/2.1 (5.1) tracks are bass managed: bass is directed from small speakers to sub, along with any LFE. 2/2 (4.0) Dolby Digital tracks are also bass managed. 2/2 DVD-A tracks are *not* bass managed. I don't know how 2/2 SACD material behaves. [Addendum: 3/2 DVD-A material on ELP's Brain Salad Surgery is bass managed properly)

    Brian, as per (II), your results with the ICBM were correct; with *any* material that has a .1 channel -- including DVD-A and SACD -- you are getting .1 channel output when mains are set to LARGE (and sub is ON).

    With mains set to SMALL, the DV-45a only has problems with 4.0 mixes: specifically, DVD-A 4.0, but *not* Dolby Digital 4.0. It'd be interesting to see what would happen to a 4.0 SACD. An ICBM solves the DVD-A 4.0 problem either way.

    Sorry again for the confusion.
