Vocals (front centre) very low level on Rhino Quadio

[oxenholme]

Oppo UDP 205 via analogue RCA/RCA leads to Parasound P7 control amplifier via analogue RCA/RCA leads to Cyrus Mono X power amplifiers (5 of them) via QED Bronze leads to Focal 1038 speakers.
When playing Rhino Quadio Blu-ray the vocals (mixed front centre) sound low level compared to everything else.
Only happens on Rhino Quadio Blu-ray. No problems on the original Chicago Transit Authority and Aretha Franklin Quadio discs. No problems on Moondance Blu-ray. No problems on Dutton Vocalion quadraphonic SACD.
Centre speaker power amplifier is switched on but (as expected) no sound coming from centre speaker.

Any ideas as to why this is happening?

does the Parasound P7 have any EQ adjustment or Tone Controls?

What are the speaker settings in the Oppo (you can choose which speakers should be active)?

These releases are quad so no centre channel! Some of the others might have a derived centre and Lfe. Moondance is 5.1. The vocals should not sound low but be mixed equally into the left and right front speakers.
