I seem to remember a caution being issued some time ago about streaming via DCD, as from a SACD. Is it safe to do so, now with update V1.5?

Where's the bass? I just performed FW update 1.5 My subs are no longer thumping like they were before with FW 1.4. Firmware 1.3 had poor sub bass and I felt I had to run my subs at a high level to get them to balance with the whole system. FW 1.4 fixed that issue and I was quite pleased with the sub levels vs. the rest of my speakers. Now with FW 1.5, my bass is gone again despite the same levels being set. I got out my SPL meter and started adjusting everything again. Subs are showing 40-50 dB when my other speakers are @ 84dB. I know that each speaker vendor and aftermarket sub design / amp levels will be different...but here's is my situation: I always start with my left front speaker on any vendor's pre/pro or receiver and set that to 0.0, then I level-match the rest of the system to that LF speaker's so all db levels are the same as the LF when microphone-measured from my sweet-spot. I am finding my subs may require a massive boost. I am definitely not lacking sub power...I have a PAIR of Crown XLS2502 amps set to HIGH sensitivity (.775 volts) and BRIDGED...I'm using the balanced inputs from theRMC-1 to my Crowns...these amps are capable of 2400 watts each into the 4 ohm bridged subs I'm using (a pair of Dayton Audio Ultimax 18's). My L and R front mains are GoldenEar Triton Ones - which have a dedicated 1600 watt sub amp built into EACH tower. All that to say I should have plenty-o-skull-crushing-bass...and I am now lacking bass having gone from FW 1.4 to 1.5. I'll try to rectify the situation by massively boosting my sub levels and possibly cutting my levels on all other speakers, but something was seriously changed with the this firmware. ***What was changed as far as sub levels are concerned from FW 1.4 to 1.5?*** A suggestion:Please post a change/revision log text file every time you update firmware. That would help those of us who have had an issue look to make sure a given issue is resolved. Secondly, changes you make on the Emo end may drive changes on my end...as appears to have happened with level setting. EDIT: - I went back in the thread and found this from Lonnie: You pretty much nailed the list. DTS locking resolved unless you are using an Oppo. Oppo is the one locking up and it doesn't look like they are going to resolve it. Test tone levels have been recalibrated. Test tone levels consistency resolved. EQ level consistency during set up resolved. Enhanced IR control Resolved issue where setting is lost if exiting menu at wrong location. Several behind the scenes things to enhance overall stability and usability. There was a report of a static/ crackling sound in middle heights, resolved. All new bass management algorithms. Lonnie I DO indeed find the above helpful, but if you could be more specific (such as cut sub level-setting by 10 dB, etc.) that would be useful info. I shouldn't have to scrub this massive couple-hundred-post thread to find that information...it should be in the firmware revision release notes / change logs. PLEASE take all of this as positive suggestions. Overall, I am happy with this piece...I think it will be even better once we git DIRAC. Thank you, Shane

With ver 1.4 sub levels were all over the place. If you had more than one sub the levels could quickly become excessive. I would set all levels to 0, re-select/configure your subs for "dual mono", power cycle the unit, then re-calibrate your levels. Hope this helps.

Also...please tell me what "Enhanced Bass" does in the setup menu. I can't find it in the owners manual. I'm about to go experiment with it. My L and R front mains are set to LARGE and all other speakers are small. My two subs are in the L and R sub out connections and I have those set to DUAL MONO per a previous post / suggestion from KeithL.
EDIT: I had searched in my paper owners manual and did not see this, but I just downloaded the online owner's manual and found this:
Enhanced Bass is a feature which allows you to combine the bass output of your subwoofers with
the bass output of your large main speakers.
When Enhanced Bass is disabled (normal operation), bass from the LFE channel is routed to your
subwoofer (or subs), bass below the crossover frequency of any speaker you have configured as
small is also routed to your sub or subs, and bass from any channels you have configured as large
is routed to the intended main speaker.
When Enhanced Bass is enabled on the RMC-1, bass from the LFE channel is routed to your
subwoofer (or subs), bass below the crossover frequency of any speaker you have configured as
small is also routed to your sub or subs, and bass from any channels you have configured as large
is routed to the intended main speaker.
IN ADDITION, bass below 80 Hz from the LFE channel is
also routed to every speaker you have configured as large (except the center channel), and bass
below 80 Hz from all main speakers configured as large (including the center channel) is also
routed to your sub or subs.
Note: Enhanced Bass is designed to boost the overall amount of bass available. Music is
rendered more accurately when Enhanced Bass is DISABLED. Also, since there is no industry
standard, Enhanced Bass may be implemented differently on devices other than the RMC-1.
________________________
I just tried Enhanced Bass. That has restored me back to the former bass response I had with FW 1.4.
I want my mains playing full range...and my subs playing L/R mains bass below 80 Hz as well. Enhanced bass does that for me. Without it on, my subs were not getting main (large) speaker bass below 80 Hz.
For other users used to mainstream AVR's (like Pioneer Elite)...you have to set your L/R mains to SMALL to get bass below 50 or 80 Hz (typically) on those products if you want subs used with those products to play non-LFE bass...the RMC-1 was acting JUST LIKE THAT without enhanced bass turned on. Had I told the RMC my mains were SMALL I would have had adequate bass, as the bass below the X-over frequency would have been sent to my subs. I had my mains set to large with enhanced bass OFF, so only my mains were getting the L/R bass, and I had them turned down a bit as they are not as capable as my Ultimax 18's when things get rocking.
I hope the above helps folks.

Thank you, Shane Shane a another way to do it would be to use a test tone and set your speakers individually to that level. I know each technique is relative but give this a shot to see if it resolves your problems. If not then you have to look at the amp section in your chain to see what’s being attenuated. The algorithms made for a tighter bass response and not an overall quieter bass.

I saw that, but this is all he said:
__________________
Among other improvements, this firmware update includes a new, totally re-written, and completely proprietary version of Bass Management code for the RMC-1.
The result is an audibly better integration between your subs and main speakers.
For this reason we consider this to be a strongly recommended update.
In addition, we have fixed a variety of minor quirks, including some that we discovered, and some that were reported to us by customers and Beta testers.
One of the more significant bugs we fixed was a crackling in the height channels that was reported by a few customers.
We also made some improvements to the speed and consistency of some menu update operations.
We also made some improvements to the reliability and consistency of the rear panel IR input and output _________________
Lonnie provided a lot more specifics. I guess I'm just looking for detailed specifics....since their settings change my settings, as evidenced by me spending my morning today trying to get my bass back after the FW 1.5 update.

I want my mains playing full range...a nd my subs playing L/R mains bass below 80 Hz as well. Actually it is a bad idea to do this. You then have several speakers with different phase responses playing the same signal. This will generate all kinds of additions and substractions and an uneven bass frequency response. It is much more advisable, even with large speakers, to have them set to "small" - all of them. Regarding your volume problem, how is your gain set on your Crowns?

... I just tried Enhanced Bass. That has restored me back to the former bass response I had with FW 1.4. ... Be careful with enhanced bass, it sends a lot of low frequency info to your mains (or other large speakers). Maybe you’re speakers can handle the extra bass, I tried it and found it too much and muddy, went back to ‘traditional’ bass management.

I'm happy again. Thanks to all who replied, and thanks to Emo for posting the description of ENHANCED BASS in the online owners manual.
I ended up doing the above...my signal chain is all good and nothing was being attenuated...it was all the RMC-1. I also followed brucelee's idea to zero-out and start over with a duel-mono setup and power cycle.
Here was my end process and final settings. Sharing in the hope that it helps others with the level setting process. Again, bear in mind that my L and R mains are full-range capable with integrated powered subs (GoldenEar Triton Ones) and I am running dual 18" subs powered by 2400 watt Crowns as well.
1) Updated firmware to 1.5
2) Checked all speaker size settings. All mine are SMALL - except L and R front mains which are LARGE (My setup is a 7.2 setup with no Atmos yet)
3) Set subs to "Dual Mono" (Center sub NONE since I have two subs)
4) Set all distances. I use a Bosch GLM-15 laser measuring tool.
5) Turned on ENHANCED BASS so that sub-bass for my L and R front LARGE mains would ALSO go to my dual 18" subs.
6) Re-booted the RMC-1 and checked to make sure all of the above "stuck". It did.
7) Level set: I used both LOW and MEDIUM test tones to make sure levels were consistent. They were consistent within 1.5 dB at both low and medium volumes. I used Medium as my master reference level.
I used the Left front main as my reference point and set it to 0.0 dB, then matched all other speakers to that level.
Adjustments ranged from as little as -.5dB to a max of +2.5dB - EXCEPT for my L and R subs which I now have set to +9.0dB. I may roll that back a dB or two, but for now that sounds pretty good with the sampling of audio I tried this AM.
7) Power cycled again - and all those settings have stuck.
I'm rocking once again after the above!

Placing one "anywhere" in the room and placing a second one in a "null" (quiet bass) location in the room has always given me the very best even response. I just would hate to deprive my GoldenEar Triton Ones of bass below 50 Hz by setting them to small. They are a true full-range Stereophile recommended tower and each one has a 1600 watt dedicated sub section built in to each tower. They are amazing for two-channel stereo material. Gain on my Crowns is maxxed out.

I just wanted to add something here....
The basic purpose of bass management is to have each range of frequencies handled by the speakers that will handle them the best. Many normal speakers, including those that are physically large, may not handle very powerful low bass well, and asking them to do so may cause distortion at higher bass frequencies.
In addition to that, asking a speaker to reproduce bass that is below the range it can physically handle makes it "work harder", and also causes the amplifier driving it to work harder.
There are also the related issues of localization and potential interactions. In general, bass frequencies below 100 Hz or so cannot be localized - we humans can't hear where the speaker they're coming from is located.
So, while we must be concerned with separation and imaging with normal speakers, we are free to locate a sub or subs wherever in the room they simply sound the best. The low bass frequencies handled by a typical subwoofer are also especially prone to room interactions and cancellations. In general, a sub will deliver the best and smoothest bass when located in one of a few specific spots in the room. And, if you have multiple subs, their relationship to each other, as well as to the room, and your listening position, is important. (This is also true if you have large main speakers whose woofers are reproducing the same frequencies as those being delivered by your sub.) Therefore, the fact that the subwoofer can be located wherever it sounds the best, and needn't be located in a specific spot relative to your other speakers, is important.
Enhanced Bass is essentially a way of overriding standard bass management in order to have both your subwoofer and your main speakers producing low bass. The benefit, especially if your main speakers have "built in subwoofers", is simply that you have more speakers making bass.
However, there are several drawbacks, a few of which are: - Even if they're capable of delivering low bass, many main speakers don't handle it as well as a sub, and asking them to do so may compromise their performance at other frequencies. - Since your main speakers must be located in particular spots to sound their best there is a good chance that those spots won't enable them to work well as subwoofers. - Since you have added more subwoofers, while you may luck out, and achieve a smoother response, you also increase the possibility for annoying interactions, and make overall setup more critical.
The bottom line is that, while it may offer certain benefits in certain situations, Enhanced Bass is usually NOT recommended for most installations.... Normal bass management offers the option of carefully adjusting and managing the crossover and balance between your sub and main speakers... while Enhanced Bass is more like "hot wiring the control".
And, if you simply find that "you don't have enough bass", unless you have a specific reason not to do so, you're probably better off simply raising the level on your sub.... (Enhanced Bass is not "the recommended way to get a little more bass".... that's why you have level trims on your processor and a level control on your sub.)
(It's also worth noting that, since it is not a standard feature, different products that offer "enhanced bass" may implement it in slightly different ways... )
Also...please tell me what "Enhanced Bass" does in the setup menu. I can't find it in the owners manual. I'm about to go experiment with it. My L and R front mains are set to LARGE and all other speakers are small. My two subs are in the L and R sub out connections and I have those set to DUAL MONO per a previous post / suggestion from KeithL. EDIT: I had searched in my paper owners manual and did not see this, but I just downloaded the online owner's manual and found this: Enhanced Bass is a feature which allows you to combine the bass output of your subwoofers withthe bass output of your large main speakers.When Enhanced Bass is disabled (normal operation), bass from the LFE channel is routed to yoursubwoofer (or subs), bass below the crossover frequency of any speaker you have configured assmall is also routed to your sub or subs, and bass from any channels you have configured as largeis routed to the intended main speaker.When Enhanced Bass is enabled on the RMC-1, bass from the LFE channel is routed to yoursubwoofer (or subs), bass below the crossover frequency of any speaker you have configured assmall is also routed to your sub or subs, and bass from any channels you have configured as largeis routed to the intended main speaker.

I would remind you that you can set up one Speaker Preset for two channel listening..... And, in that one, set the fronts to large, and not use the sub.....
And set up the OTHER Speaker Preset for movies..... And, in that one, set the fronts to small, and use the sub with standard bass management....

Good idea with the 2 presets Keith! I actually also use "small" for music. The bass of the DBA is just superior... But feel free to experiment, always a good thing!

I wish there were THREE presets. I am learning a lot here. I just figured out that the ENHANCED BASS setting only appears if you set the fronts to LARGE...which makes perfect sense...because if I choose SMALL for the fronts they are sending their bass frequencies to the subs just like ENHANCED BASS. Here are my two Presets right now: 1) Fronts LARGE, ENHANCED BASS ON (fronts play full-range, and bass below 80 Hz from all front channels is also routed to subs). 2) Fronts SMALL (bass <50 Hz goes to subs) A third preset would be nice so I could also save: Fronts LARGE, ENHANCED BASS OFF My plan now as I continue experiment is to set up presets 1 and 2 so that both have FRONTS LARGE and 1 has ENHANCED BASS ON and the other has ENHANCED BASS OFF so I can compare the two. Keith, is that what you would do if you were running my speakers (GoldenEar Triton Ones) - or would you set them to SMALL? Or would you have one PRESET set to SMALL and the other LARGE ...and on the LARGE would you set it up with or without enhanced bass? Please do consider allowing another preset (or two) in a future firmware revision for the reasons stated above.

I believe enhanced bass is also sending the sub content (the .1, or LFE channel) to your front mains, which is why it’s not REALLY recommended in very many situations. That LFE can really muddy up your mains. I may be wrong, but I think this is the case, right KeithL?

You are correct about how it works per the owners manual:
Bass below 80 Hz from the LFE channel is also routed to every speaker you have configured as large (except the center channel), and bass below 80 Hz from all main speakers configured as large (including the center channel) is also routed to your sub or subs.

That is only sending low freq to the subs, not vice versa.

There is actually a correction (or change) to what's in the manual..... (This is true for the RMC-1, RMC-1L, and XMC-2..... )
When Enhanced Bass is ON, and a speaker is set to large, bass below the crossover point continues to be produced by the speaker, AND IS ALSO SENT TO THE SUB. However, the bass from the LFE channel, which is routed to your sub, is NOT routed to your large speakers in addition to the sub.
The reasons why it isn't recommended are: - The whole reason for adding a sub is to allow it to handle the frequencies that are difficult for normal speakers to produce in large amounts. (The assumption is that a good sub is optimized for producing lots of low bass while regular speakers are not.) (If your main speakers have real subs in them, then you don't need a separate sub. If you need a separate sub, then it's probably because your main speakers don't do a great job with low bass frequencies.)
- By using your main speakers as subs, you are increasing the total number of subs, and so making the process of setting them and arranging them optimally around the room much more complicated. (And, since your main speakers are limited to specific room locations, you do not have the opportunity to put them in the optimum location for a sub.) - Bass management is carefully configured to divide the various frequency ranges between your speakers. (The whole idea of Bass Management is to divide up the frequencies so each speaker handles only the frequencies it's optimized for... by using Enhanced Bass you are bypassing part of this process. This make sit less likely that you'll be able to achieve a smooth transition between your sub and your other speakers. )
You are correct about how it works per the owners manual: Bass below 80 Hz from the LFE channel is also routed to every speaker you have configured as large (except the center channel), and bass below 80 Hz from all main speakers configured as large (including the center channel) is also routed to your sub or subs.
