Wondering what those 4 LEDs are, they are inside the unit.
I am no electrician, but looking at the ICs and googling I find the largest one being an analog multiplexer/demultiplexer, one being a VAC (for compressor?) and most being the same type of OP amp, some different types though. There are a few smaller ones, and one medium size I can not read.
The VAC sits straight in the middle of the compressor knobs and led, so is this compressor of the VAC type, could the 4 LEDs have anything to do with compression?
There does not seem to be any ICs on the back.
Does anybody know how to tell if this is all analogue or if there is DAC-ADC involved.
There exist small converters with only 8 legs, but no DSP chip what I can see.
It does ask for lots of current. 400 mA I think. Is that a clear sign it is digital, or is that common for several effects and gain stages?
What do you think?
