If the turntable has a separate ground wire, attach it to the
Ground terminal on the Precision Phono Pre to reduce hum.
Connect the RCA outputs to the appropriate inputs on your mixer
or stereo receiver (Line input, or an unused tape input). If the
mixer does not have RCA inputs (on any of the channels) a ste-
reo RCA to dual mono ¼-inch male cable may be needed to con-
nect to the mixer line inputs.
