A:AnswerYou can either connect the turntable to the (2 TR) Left and Right RCA inputs on the mixer or connect it to two 1/4" line level inputs (one for the Left and one for the Right channel) by using two mono RCA female to mono 1/4" male adapters. In either case, make certain that the phono preamplifier that is built into the turntable is turned on. That is, the preamp selector switch located on the rear of the turntable has to be set to the LINE position.
