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
