User manual RANE PS 1

[. . . ] 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. [. . . ] This choice should only be taken for very short cable runs (less than 10 feet) and where hardware interconnection incompatibility demands it. Grounding Proper grounding of phono stages cannot be over emphasized. 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.
