The PSC RF SR 4 Slot Rack contains built in low noise, high current RF amplifiers and distribution
circuitry. The 4-way, active RF splitters will feed high quality RF to your four slot receivers. This
rugged device was developed using the latest super low noise RF amplifiers and is offered in
several models that operate over the following frequency ranges:
Model # Description: Frequency Range:
MRFSRS PSC RF 4 Pack, “Single Band” 470-700Mhz
MRFSRD PSC RF 4 Pack, “Dual Band” 470-618Mhz and also 940-960Mhz
MRFSRW PSC RF 4 Pack, “Wide Band” 470-960Mhz
Its two RF inputs are traditional BNC connectors for ease of use in interfacing with your external
antennas. Each of the four slots offers a typical Rf signal isolation factor of 24 to 28dB between
radio receivers. The PSC RF SR 4 Rack also has the ability to power external powered antennas
or remote line amplifiers. There are two front panel mounted switches on the unit. One is
marked “MAIN POWER” and this controls the overall power to the unit. The second switch is
marked “ANT PWR” and this switch controls the power being sent to an external powered
antenna or remote line amplifier. Both switches are accompanied by panel mount LEDs for easy
to view operation. The entire unit is powered from any source of external DC power of 12Vdc @
approximately 185mA through the rear panel mounted 4 pin XLR power connection. The unit
can also be powered from 90 to 240VAC for fixed installations. On the rear of the unit there are
eight TA3M mini XLR output connectors. These provide audio output from the four slot receivers
as well as DB-25 connector that offers all the audio outputs on one convenient “audio snake

connector”.This DB25 Connector is wired to the industry standard “Tascam” wiring standards
thus making off the shelf cable snake assemblies readily available through Amazon and many
audio dealers.

RF DISTRIBUTION:
Your new PSC RF SR 4 Slot Rack contains RF distribution designed to provide proper, clean RF
distribution to your Slot Receivers. Each half of the diversity RF distribution contains a built in
DC bias circuit designed to be able to power external remote powered antennas and/or remote
RF amplifiers, an RF limiter to help guard against RF overload, RF bandpass filters (various ranges
available), a very low noise RF Amplifier, and a RF splitter. Each half of the RF circuitry also
contains its own, dedicated power regulation circuit to help eliminate RF cross talk and
intermodulation issues.

STEP BY STEP USE GUIDE:
1. Install your slot style receivers into the openings on the front of the PSC RF SR 4 Slot
Rack noting the correct direction of the DB-25 connectors. Gently slide the receivers
into the slots until you feel the DB-25 connectors line up. Once you feel the connectors
line up, firmly press the slot receiver fully into place. Lock your receivers into place
using the M3 Metric thread screws on the receivers.
2. Connect your audio output cables from the eight TA3M audio outputs or from the DB-
25 connector to your mixer or recorder’s inputs. Either connector type can be used with
either analog or AES digital signals. Please note that the DB25 multi-channel audio
snake connection is wired using the industry standard “Tacam” wiring for ease of use.
3. Connect either a 12 VDC power source to the 4 pin XLR external power connector or
connect the unit to AC power using the AC power receptacle.
4. Connect your two receiver antennas to the RF input BNC connectors on the rear panel
of the unit. When using powered antennas or remote line amplifiers, turn on the
“Antenna” power switch. For all other uses, leave this switch turned off.
5. Power up the unit by turning on the main power switch located on the left hand end of
the front panel. Note that the BLUE LED located adjacent to the powers switch will light
up power when the unit is turned on.
*NOTES*
1. Different brands of wireless receivers require their own specific brand made
adapters to work with our Four Pack. These are the same adapters required to install
the slot receivers in an Ikigami or Panasonic camera. For example:
Lectrosonics SRB requires their “SRUNI” kit.
Wisycom MCR42 requires their “SCK42-IK-PSC”kit.
Audio Limited A10-RX no adapter needed.
