The power supply shall be U.L. listed, C.S.A. certified, and CE approved. Each input shall feature selectable cartridge loading capacitors of 100 pF, 250 pF and 425 pF. RFI input filters shall be provided. The unit shall have switchable infrasonic filters designed for a cornerfrequency of 15 Hz with slopes of 18 dB/octave. The accu- racy of the RIAA equalization stage shall be 0.1 dB for all specified frequencies. The output stages shall be of the active cross-coupled design and capable of driving at least 1000 feet of cable terminated in 600 ohms. The unit shall be a Rane Corporation PS 1 Phono Stage. Unbalanced RCA Output Interconnection While not recommended, it is possible to run the output from the PS 1 to other equipment in an unbalanced fashion. 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 empha- sized. Be sure to connect the turntable ground wire to the PS 1 Chassis Ground thumbscrew. Additonally, it is recom- mended 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. PS 1 HIGH-FIDELITY PHONO STAGE Application Information Phono Cartridge Loading Capacitance Use the slide switch to select the desired loading capaci- tance. If the correct capacitance is not known, use the following table as a guide: Cartridge Capacitance Audio-Technica (all) 100 pf Pickering (all) 250 pf Shure V15s and MEs 250 pf Shure M44s and M55s 450 pf Stanton (all) 250 pf 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. Connect the shield to the GND terminal.
