What are the purpose of "Tape" and "Rec" preamp ?


Hi,
Beside the usual RCA input (CD, Aux 1, Aux 2) and single RCA output on the back of my pre-amp, my pre-amp also has 2 other RCA connectors named as "Tape" and "Rec".

On the front side, it also has separate knob with "source" and "tape" choice.

Can anybody advice if this "Tape" and "Rec" ar actually similar to "Tape in" and "Tape out"? If yes, which one is which?

I am planning to experiment using DSP/equalizer.

Thanks a lot in advance for the advice

Thanks all for the perspectives.

Just one last check, can I still use the volume control on my pre-amp if I use "Tape" and "Rec" as "Tape in" and "Tape out" for equalizer?
You can also use the "out" for a headphone amp. I'm surprised so many current preamps offer these...maybe in anticipation of the reel to reel boom that is (barely) happening.
Tape out is generally a fixed output level. Tape in is controlled by the preamp volume control.
