Hello, I own an original Pass Aleph 1.7 preamplifier.; here's my question:
are the 4 inputs electrically identical?
This is the manual:
"Next to the inputs on the rear panel, the preamplifier offers tape outputs through both XLR and RCA connectors. This output is a direct connection to inputs 1, 2, and 3 when they are selected from the front panel. Input 4 is deliberately not available through the tape output connection. Input 4 is designated for use with a tape recorder if you have one, and we have arranged that it will not place its output on the tape out, which will prevent you from accidentally creating a feedback connection with your tape machine."
My technician claims that output 4 is quieter and with less distortion than the others.
Questions:
1) Is it a smart move to use input 4 for the main source (cd)?
2) Is it useful or wrong to use the xlr shorting plug even in the inputs that I don't use at all?
3) What is the optimal setting between the gain potentiometers and the volume control?
Thanks.

Input 4 is just connected after the tape monitor switch instead of before it.
There is no difference in performance at all.
Most preamps do this for the tape inputs to prevent positive (damaging) feedback.
Using the shorting plugs is fine.
The volume control should be near the center in normal use.

Thanks Rayma.

This is very strange, considering that input 4 is near the big transformer!
😕
Best regards,

I doubt the tech has actually measured that. You can be confident that
NP did proper design work on his creations. Second guessing is not needed.
Of course you can use the input of your choice, since they are all equivalent.
Don't let other people make you unhappy with your stereo for no reason.
