It seems like both 1200s (modified to be self grounded) have a hum when plugged into the 96. The DJM didn't have that problem. Anyone has experience with diagnostic/fixing this?
UPDATE: I jerry rigged a fix to verify an hypothesis and it turns out the outer (ground) connection of the phono RCAs on the 96 are not grounded properly. Those are connected to the ground on the 1200 (that's the internal grounding method) but the 96 requires the turntable ground to also be connected to its grounding pin which leads me to believe that they don't connect the RCA ground with the mixer ground on the phone inputs. UNLIKE EVERY OTHER MIXER ON THE FACE OF THIS PLANET
@damien It is funny to me that you call them A&E. That's accident and emergency over here.
@mark LOL. I'm just lazy to type the whole name.
@damien So what you're saying is that your manually modded user hacked warranty invalidating 1200s don't work with the 96, but regular unmodded as God intended 1200s with an earth wire do? Those charlatans at A&H need exposing. Down with this sort of thing. 😜
@damien Have you tried putting them on the same or a different circuit?
@astromech so I unplugged everything in the back and just plugged one turntable. Tried same circuit with both power and RCA cables way clear of anything else. I haven't tried a different circuit yet. Good idea.
@damien I seem to remember mark saying that grounding mods for 1200s are a bit flakey... wait, are you using the 96 as a foot rest already?
@astromech nope... it's my only mixer now. The DJM900 can take the same input at full gain without a spec of noise and the 96, at normal level gain has a very audible hum.
@astromech different circuit, same hum.
