connecting parasound preamp to amp

I have not used my Parasound HCA 1500A amp in some time and am setting it up again today to my Parasound P/LD 1500 preamp but am not sure to which set of outputs on the back of the preamp the amp gets connected to. The preamp has 3 options for output: Balanced output jacks (3 prong non RCA) and two options for Unbalanced output (RCA jacks): Direct Polarity fixed and normal
polarity switchable. Should I connect the amp to the preamp’s direct polarity fixed or to the normal polarity switchable jack? What is the difference. I only have a RCA cable, and the amp has a RCA input so I will be using a RCA cable. Thanks.

Sorry.
I thought I had your manual but it was for the P/SD1500.
I see it's a hard manual to find.
I found a link but you need to log in and I can't at the moment.
I feel they expect us or the owner to KNOW which does what. I know polarity but do you have another switch to manually change the polarity on the back also to go along with that manual switchable switch?
I'm still trying to learn the 3 or 4 types of speaker connection types and how to wire them. A friend told me there are 3 and 4 wire speak-on connectors
A normal setup with the P/LD 1500 or 2000 should use the "normal" outputs that offer the opportunity to switch polarity. Some people like to experiment and invert polarity with recordings they know to have been recorded in an unusual way. Those preamps offered the option of switching easily. I also think they were designed in the early 1990s when potential owners of the preamps would have been likely to have wanted the option to invert polarity to match the amps they already had. No lost sales that way, but the option was in no way a sales gimmick.
On the other hand, Parasound amps do not invert polarity so the direct outputs are also a sound choice. They just don't offer the ability to switch polarity or play around with different recordings. It may be of benefit to try both sets to see if there is an audible difference. The direct outputs may indeed offer a more direct signal path and sound better because of it. Chances are there is no difference though since those older preamps were very well designed.
