Control room out (RCA), headphone jack mutes the control room if it is plugged.
The standart for this small mixer, 4 mic, 2 stereo, 1 in, Tape in & out ... what plug 2/3 stuff as we hear.
Personally I love the sound of this mixer with a micro electro-static in hmmmmmmmm. With enough reserves to never having heard saturate. The little EQ is more than satisfactory.
I am very happy, light and compact.
Does its job handily.
Do not forget that this is one of the first compact mixer.
