Equalizer in a Hi Fi system

MQ112 is analog. DSP is digital signal processing. It’s equalization performed pre dac in the digital domain 

@tlcocks Ty. Could u please explain what each one would be used for ? That’s the only thing I’m not understanding. And so even if my listening is only digital meaning cdp and I have an analog equalizer is that ok ? 

Your cdp is a digital source. That code gets converted to analog waveforms either in that machine or you stand alone dac or your preamp. Tell me your components and I’ll explain how it all works. Also what cables used also. 

All digital signals MUST get converted to analog by the time they hit your speaker wire. Now if you’re wireless…can all occur in one box. @tattooedtrackman , tell me your components and cables. By the way, I don’t know where on Audiogon to find everyone’s gear list. And I don’t know how to post mine. 

And yes, it’s very ok to have cdp as source and analog EQ running into your preamp
