In addition to granular delay control on each sub output (good call, this could really help fine tune) I would like to see an option to set the low pass crossover to the subs without a high pass on the mains (when using large mains to allow more overlap). There is an option to do this with multichannel DD/DTS but I'd like an option to do it with stereo.

While I'm on the subject, I would like a better explanation of the "Sub Trim" on the "LFE Trim" menu - is it duplicate to the sub trim on the Speaker/Level Trim (I don't think so), seems like it applies to the All Channel Stereo mode? That would make sense since there are explicit settings for DD/DPL/DTS/Stereo but the language the manual uses, overall far better than other products, still leaves me with this question. Are crossovers applied before the EQ for each channel or after? Come to think of it, the 976 is applying bass management to the analog inputs too (this is huge, prior Outlaw products had a fixed analog option for analog bass management or used an ADC) - are the crossovers always analog or are they digitally processed for digital sources?

No, I still have questions. They aren't getting in the way of enjoying the sound though!

I am currently operating under the impression that the EQ is applied to each source channel and then the crossover is applied. That means that a +3db bump at 30hz on the front left channel will be passed to the sub if using a crossover (small speaker setting), but a +3db bump at 30hz on the sub EQ will only be applied to the LFE channel source.

I had the 976 on a test bench and was convinced that bass management was being applied to an analog input. I fed a DAC into an analog stereo input then plugged powered monitors into the sub and left front XLR outs and confirmed full range (maybe bass limited?) on one speaker and bass only on the other. I didn't invest the time to confirm that the crossover point moved (previous outlaw products had a fixed 80hz crossover for analog), or that the "full range" was actually bass limited as it should be.

I think "Sub Trim" on the "LFE Trim" menu is for managing the sub gain in modes where channels are summed below the crossover, as occurs with All Channel Stereo and with the "Bass Augmentation" modes.

Well, I heard back from Outlaw regarding the possibility of a future update to allow custom input names.

Unfortunately, they said they have no plans to make such an upgrade. :-(

Thanks for asking them. Im betting the answer does not surprise any of us. All we are doing is giving Outlaw food for thought with their top-of-the-line processor. If it ever comes to be !
I do wonder why though, when its said they monitor these forums, that Outlaw doesnt pipe up and say so right here !!
I suppose they just let us all vent !
