Quick question on cables.

ok, here's my current cable set up:

Turntable <-RCA + Ground-> Mixer,

Mixer [Line Out]<-RCA/TRS Dual Cable-> MPC [Record In]

Monitors <-TSR-> MPC [Stereo Out]

now with this, the only way for me to be able to listen to what's on my turntable is to get in Record Mode in my MPC

so i was wondering if i can just connect my Mixer [Line Out] to my Monitors via RCA cables so i can hear what's playing on my turntable?

i have KRK monitors by the way. and they have the TSR, XLR, and RCA inputs.

try input thru on>off
