[. . . ] DATA SHEET / MANUAL PS 1 HIGH-FIDELITY PHONO STAGE General Description The Rane PS 1 High-Fidelity Phono Stage is a complete professional RIAA phonograph stereo preamplifier designed for remote turntable locations. [. . . ] Be sure to connect the turntable ground wire to the PS 1 Chassis Ground thumbscrew. Additonally, it is recommended that the PS 1 chassis be earth-grounded. Due to the remote power supply, the chassis is not grounded through the AC line cord as normally expected; therefore it may be necessary to run a separate wire from the PS 1 chassis thumbscrew to a good earth ground (such as a grounded electrical outlet box). TRICK: For absolutely belligerent installations that defy all hum solutions, try connecting the interconnecting shield to the chassis Ground thumbscrew-- not the ground terminal, and tie the other end to the chassis of the mixer. What this does is tie the turntable chassis directly to the input chassis--sometimes this solves things. Balanced Output Interconnection Use only high-qualitity two-conductor shielded cable (Belden 8451 or equal). Connect the two conductors to the positive ("+") and negative ("­") #6 screw terminals.
