I'm a new user of a used mixpre. I've read endless comments about how quiet, and low noise this unit is. I have not had chance, yet, for field recording. I've been busy listening to ambient house noise - frying onions, refrigerator hum, guitar, etc..... When nothing is plugged in (no mics), and I listen only to headphones , and increase the gain past 7, 8 o'clock, what is the noise / hiss I am listening to? Will this all be masked by signal when one is introduced? It seems quite strong, likely to color quiet passages of recording. Is this a service issue? an undisclosed artifact at time of sale? or just what it is?
Sorry if this has been addressed someplace else. I could not find a thread.
Thanks in advance .....
