Made all of those setting changes but sound no louder. Very strange.
Oppo 95: Low Output via Stereo RCAs
I just purchased the Oppo 95 in apparently excellent condition.
Firmware: BDP9x-82-1009
I set Audio Settings to HDMI off, 192KHz on, Stereo Signal downmixed, Dynamic Range Control on, Output variable on.
But the output of my ancient but trusty JVC XV-NA70BK DVD player is much louder than the Oppo-even with the 95’s variable output set to maximum.
The Oppo’s analog RCA outs are 2.1V; the JVC’s are 2.0V into 10K ohms. My amplifier’s input impedance is 10K ohms but I have to crank its volume up high when using the Oppo. The JVC’s stereo outputs are much higher to ever need to do that.
Neither "output impedance" nor "output resistance" appears in the JVC owners manual nor the service manual.

However, notice that in the service manual’s table of contents that the schematic diagram which should have been between p. 2 and 8 are omitted. Analyzing and comparing the JVC and Oppo analog output circuitry could have explained why the JVC output was so much louder.
Oppo service support thanked me for the info but could offer no explanation.

This probably has nothing to do with the problem but the first two discs only have Dolby Digital audio while the other only has DTS-HD MA. But while the former audio format is lossy and the latter lossless and sounded more dynamic, it certainly shouldn’t and didn’t effect output level.
Please advise

I did turn volume to 100%; no help. Neither did turning off Dynamic range control. Next I will go into speaker config settings and look what levels they are even though the manual says on p.17 " "The STEREO AUDIO OUT terminals automatically down-mix the multi-channel audio source into the stereo signals. However, STEREO AUDIO OUT will NOT be affected by the “Down mix” modes and other speaker settings in the Audio Processing of Setup Menu (described in the page 68)." If n/g, then as someone at AVS and Steve Hoffman suggested, it’s possible that in order to prevent overloading the stereo outputs by the 7.1 surround sound analog outputs, that rather than appropriately buffering (isolating) the stereo outputs Oppo instead applied some overall gain reduction to them. Thus, I will try connecting the front surround sound speaker pair and then go into settings and enable downmix and see if that stereo pair will give me higher output voltage. As for mods, AFAIK there were none. I will ask the ebay seller about that. I have to get in touch with him and ebay anyway because the player was advertised as region free. But it’s not as it won’t play this "all zone" PAL-encoded DVD from South Africa. https://raru.co.za/movies-tv/37567-ride-the-high-wind-dvd The image rolls and is monochrome not in color. And the player gives and "Invalid Region Code" message when loading this DVD set from the Netherlands . https://www.catawiki.com/catalog/dvd-video-blu-ray/carriers/dvd/4166045-het-derde-seizoen So I will be asking for reimbursement to purchase a mod kit like this. http://bluraychip.dk/product.php?id_product=17
