Time stretching/pitch shifting without DSP, possible or not? Options

[bennetng]

I mean time stretching without changing pitch and pitch shifting without changing speed.

I ask this because my friend recently purchased a turntable (Stanton ST150) and it has time stretch function.

The manual says

Note: This turntable has separate analog and digital circuits. If you are
looking for a purely analog signal, use the Phono output. For access to
the Key correction feature use the Line output or S/P DIF output.

Note: Key lock and Digital output
processing is only available when the LINE
output is used.

So from my common sense and English level (not my native language), the line out is in fact converted from digital. But my friend insisted on thinking that the processing is done in analog domain and said if EQ can be done in analog domain, why time stretching/ pitch shifting can't?

What is your opinion?
