Hi. Three questions: 1st) RCA out volume is fixed - or also controlled by knob? 2nd) RCA muted while headphones plugged in? 3rd) Sound muting output relay equipped (anti-speaker-plopp at power on-off)? thx.

Hi Picky,M3 RCA volume is fixed, and headphone output at the same time, no mute switch.RCA output has muting function, not by relay, but using semiconductor,and the headphone amplifier IC has muting function.So, M3 will not has much pop noise.Thank you.
