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. Capable of driving extremely
long lines, and intended primarily for permanent archival
applications such as libraries, schools and museums, the PS 1
solves the problem of finding a reliable high qualitity phono
stage for consultants and contractors. Club designers also find
the PS 1 useful when needing to expand existing (or new)
mixers which have no available phono inputs.
The PS 1 has all the necessary features for a complete
remote installation. These include the correct loading capacitors for all popular phono cartridges, and properly designed
rumble filters that remove all dangerous infrasonic* signals
without interfering with the audio signals.
The PS 1 Phono Stage is supplied with a U.L. listed,
C.S.A. certified, CE approved, safety extra low voltage
(SELV) remote power supply for the best possible performance and safety. The 230 V versions of the unit and the
power supply each meet the CE EMC directive 89/336/EEC.

Application Information
Phono Cartridge Loading Capacitance
Use the slide switch to select the desired loading capacitance. If the correct capacitance is not known, use the
following table as a guide:

Pickering (all)
250 pf
Shure V15’s and ME’s
250 pf
Shure M44’s and M55’s

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.
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 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.
Architectural Specifications
The phono stage shall be a stereo stand alone unit with
remote power supply. 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 corner
frequency of 15 Hz with slopes of 18 dB/octave. The accuracy 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.
