Fosi Audio LC30 Speaker/Amp Switcher & Meter

[soundwave76]

Hello, could you please specify what kind of system you want to include? What are the devices in front and behind? Are they all digital signals?

Two sets of Genelec SAM speakers. AES digital signal fed to both, sources Bluesound Node 2i and a PC/Mac.

Silly idea: get a really cheap chip poweramp for 20 moneys or so, just to drive the LC30's meters.

I would like to ask in what scenarios can voltage or current be displayed?

I am not sure if I understand the question correctly. Below is an example of a VU meter, that basically displays voltage, but in VU, ie volume unit form:
For current display, I don't recall seeing one on an audio amplifier, that's too bad as it isn't hard to do. However, as long as there is a true (such as McIntosh's iirc) power (Watts) display as well as voltage display simultaneously, the information is there, but if only power is displayed then it isn't useful and that's my only point.
