Hello everybody!!

A SPL Volume 2 preamp is coming my way, and I'll be looking into adding remote controlled volume to it.

Looking around, there's this kind of motorized volume control kits: https://www.aliexpress.us/item/3256802832503035.html

They seem relatively straight-forward, but there's not much space inside the SPL preamp for adding the control kit to it:

At any rate, would you think this approach is feasible?

TIA!! 🙂

This is definitely doable, it looks like there is plenty of room in SPL Volume 2 for modifications, maybe the ALPS27 motorized potentiometer might not fit in the existing volume control pot location, but there are plenty using smaller pots or rotary encoders remote control module should be small enough to accommodate.

However, it may introduce noise into the device, which is something to consider and some shielding may need to be applied.

The SPL Volume 2 has arrived, and it's really good! 🙂

I'll definitely have to take a look at its insides, because there are signs that it's been opened before. Well, I already meant to open it anyway. 😎

Chrisng, regarding shielding, what would you mean? Physically shield the potentiometer, or shield the input/output lines to and fro?
