is to use the Mono Movie DSP audio mode. Then all my speakers are now playing. ...Also with Full Mono audio mode and All Chl Stereo DSP audio modes.
But the best is Mono Movie DSP audio mode.

It seems to me that my Oppo 103 is indicating 2ch MONO, and not Stereo; is that possible, because that is what seems the most logical explanation to me.

Some AAC 2ch and MP3 2ch @ 48kHz audio modes are mono, and others are stereo.
Is that possible?

Would be nice if was well indicated (delineated) by the Oppo 103's Info display, and also by my pre/pro's Info display.

What do you think?

If it was easy to setup, you must have done something wrong as it's supposed to be a right of passage to struggle with getting SMB shares working properly.

I know the 105/105D's is .5 db per step.
In 1dB steps. *** Correction: It has been refined to 0.5dB steps (firmware update, for the 103).

Yes it works in Stereo mode (mono stereo it seems), but I want it all around from Dolby Pro Logic IIx and IIz. ...And it does not work as the sound is only coming from my center channel speaker.

PLII probably needs at least stereo to be able to process, I guess. If it is two-channel (mono) audio, then you'll get sound only from one channel, the center one. ...And nothing @ all from the other four, or six, or, eight, or ten other channels.

So, no good with PLII, PLIIx, PLIIz, all dts audio mode flavors, and all THX audio mode flavors.

...Only with some DSP audio modes: Full Mono, All Ch Stereo, and Mono Movie. ...And nothing else.

Since he normally uses the HDMI connection to his Anthem pre-pro, there would be no need for him to spend the extra money on a 105D as the 103D would suit his needs just fine. But for beta testing purposes, the 105D has more stuff (extra inputs, extra analog outputs) that can be tested.
So, Bob purchased the 103D for himself?

...Or is he using it for his own personal use and pleasure @ home with his wife and kids and friends?

And of course I assume that it is connected to his Anthem Statement D2v, through the HDMI connection, and that Anthem pre/pro is also being constantly tested.

My conclusion: Bob is always testing for his own personal pleasure, and ours.
So it don't matter what he's using or not, it's all his, and ours to gain from.
What a guy! ...Bob

The Analog output Volume step size for ALL the 10x family of players is the same in current firmware: 0.5dB per Volume step, where Volume 100 (or Volume FIXED) represents full output and anything less than that is attenuated from full output. Volume 0 is a special case -- implemented as "Mute" -- including Muting the digital audio outputs.

Note that when using DSD-Direct-to-Analog Conversion, the 103 and 103D lose the ability to control Analog output Volume (along with all the other audio processing). You get Volume 100 regardless of how it is set. (But MUTE still functions.) The 105 and 105D *DO* have the ability to control Analog output Volume even when DSD is sent directly to the DACs.
--Bob
Jeez, I needed to be updated as well. ...Refinement; we all can use some of that in our lives, for sure.

I thought it was different for the 103 and 105. 105 is digital, 0.5db per step. 103 is analog?

With HDMI audio that is handled as a standard function by your HDMI-capable AVR.

With Analog audio, there is also the possibility of "bass steering" from the other speaker channels into the subwoofer channel due to the action of the crossover. That requires additional attenuation of the Subwoofer output to preclude clipping.

So if a Crossover is active, the Subwoofer RCA Analog output needs +15dB boost to match the other RCA Analog outputs. With no Crossover active, it need +10dB boost. If passing the Analog Subwoofer signal through an AVR, odds are it will provide +10dB boost by default. But in any event you can accomplish the needed boost by adjusting the Volume knob on the subwoofer.

You can ignore all these details if you take the simple step of just checking levels with a calibration disc and an SPL meter -- adjusting the Volume knob on the Sub as needed. When the Sub SPL measures the same as the main speaker SPLs (for any given Volume), then you are good to go.
--Bob
I think that my pre/pro takes automatically care of that; from the HDMI audio convoy.

But! From the multichannel analog connections, I have to make manual adjustments.

And! No way, no way ever that I am going to touch the Gains on my subwoofers themselves.
Everything has to be done from the pre/pro, and the Oppo.
It took me forever to have my two subs properly balanced with each other and with my room,
from their Gain controls. I would not fool around with them again.
Besides, the sound is better from the HDMI connections (with Audyssey engaged), than from the multichannel analog connections (without Audyssey REQ).

--Bob
Every pre/pro (and AV receiver) with multichannel analog input, should give us access to channel level trims, at the very least, plus a LFE/subwoofer gain control (special boost from 0 to 20dB in 0.5dB steps).

99.5% don't offer any of that, and in my honest opinion (wise), it is a major oversight. ...How could they?
...Probably to save money from adding a simple and inexpensive ADC chip. ...?

What you think Bob, your Anthem pre/pro has that?

Of course they're for the analog outputs, but they operate within the DAC in the digital domain before the signal is converted to analog.

Try turning off the Gracenote look-up feature and see if that cures the issue.

Yes, my AV receiver has that.
But I decided to put everything to 0 at the receiver analog settings, and enter it correctly on the Oppo

What calibration disc would you recommend for this? I don't want to get more than one if possible.
I don't have any yet (besides the free AVSHD patterns, which were quite helpful so far, also during video calibration of my TV).

This AIX Audio Calibration also has special LPCM test tracks to measure the volume of a subwoofer? Pink noise from a subwoofer is always difficult to measure with SPL meter.
I am doing it now with low frequency sweeps that I got somewhere from the internet burned on a dvd-r.
For audio calibration, Spears & Munsil II is not that good?

I didn't mean gain in regards to sensitivity matching capability. I meant it more in regards to the incremental steps. The big drop in voltage from full output (100) to (95) seems a bit drastic; thus my comment regarding if it's logarithmic or not... I'd have to incrementally step through the volume and plot the voltage output to know this. Sorry for the confusion.

It's pretty much standard. Each volume step (increment/decrement) of the Oppo 10x players represents .5 dB change. It's standard logarithmic (dB's are related to voltage logarithmically)....every 6 db represents a halving (or doubling) of the voltage......So, on the Oppo 10x players, every 12 clicks/steps of volume will be half or double the voltage output.

One note about the AIX disc - volume level matching between speakers is supposed to be done with band-limited pink noise (500 Hz to 2 kHz), and I've found the AIX disc does NOT have band-limited signals on it. When I play the volume level matching patterns from the AIX disc, the subwoofer engages, so it is obviously going down below 500 Hz. This doesn't happen with the Spears & Munsil II disc, which does have correct band-limited pink noise for the normal and LFE channels.

This only applies to the speaker level matching patterns.

Hmmm, thanks for the warning.
So I guess the AIX disc is not that good for audio calibration since it does not have a decent pink noise...

It's not the best choice for level matching. It can be used, but you'd need to do things like make sure your crossovers are all set and still operational, yet still disable the sub completely so that it doesn't contribute to the volume measured.

Also, most common SPL meters (and especially the cheap ones) are most accurate in that 500 - 2k range, and can lose their accuracy in the lower frequencies, so a band-limited pink noise is best for level matching.

Personally, I just use the receiver's Audyssey setup to do the level matching for me, but I'm all digital and that doesn't work with the Oppo's analog outs.

^If I use the band-limited pink noise from my receiver to volume match the subwoofer it is difficult to measure correctly since the SPL meter jumps around quite a lot. It does not do this for the other channels.
So I was hoping this AIX disc has some useful test tones for subwoofers where the SPL is more steady... But it seems it has not?

I got my 103 today. I find that the audio just doesn't have that oomph.
Watched the dark knight rises on the weekend via the xbone and then watched it again on the 103 and the oppo just misses that certain extra oomph in the sound.
Am I the only one experiencing this?

^ How are you set up to play audio, and are you sure you were playing the lossless track from that disc?

In the OPPO, check that you have Dynamic Range Control OFF and Secondary Audio OFF.

Check your speaker levels -- particularly your Subwoofer level -- using a calibration disc.

Well, thanks to Oppo for that.

* Which AV receiver do you have; a Denon/Marantz one?
