noise RF amplifiers and is offered in several models that operate over the following frequency
ranges:Model #Description:

Its two inputs are traditional BNC connectors for ease of use in interfacing with your externalantennas. Each of the SMA outputs offers a typical isolation factor of 24 to 28dB between radio
receivers. The PSC RF Multi SR Four Pack also has the ability to power external powered antennas
or remote line amplifiers. There are two front panel mounted switches on the unit. One ismarked “MAIN POWER” and this controls the overall power to the unit. The second switch ismarked “ANT PWR” and this switch controls the power being sent to an external powered
antenna or remote line amplifier. Both switches light up when in use. The entire unit is poweredfrom any source of external DC power of 12Vdc @ approximately 195mA. On the left side of theunit there are four TA3M mini XLR output connectors. These provide audio output from thethree slot receivers as well as a high-density DB-15 connector that offers all of the audio outputs
on one convenient “audio snake“connector. In addition, there are two chassis mounted SMA

connectors on the left side panel of the unit. These offer two additional RF outputs that can beused to feed another PSC RF Multi SR Four Pack or PSC RF Multi SMA or an outboard receiver orother similar device.
The PSC RF Multi SR Four Pack is also equipped with a built in Battery Distribution System. There
are two battery power inputs on the left side panel of the unit. These two external battery inputs
can be used with various rechargeable battery types and sizes. In our industry these batteries
would typically be NP-1 or the newer “Smart” batteries. You can also use Sealed lead acid (SLA)
batteries, V-lock batteries and many other types. By equipping this new product with two battery
inputs, you can use two batteries at the same time for use with heavy equipment current loads
or for extended run times. You can also use one battery by itself or one battery with our optional
AC power supply.

RF DISTRIBUTION:
Your new PSC RF Multi RD 4 Pack contains RF distribution designed to provide proper, clean RF
distribution to your Slot Receivers. Each half of the diversity RF distribution contains a built inDC 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 rangesavailable), a very low noise RF Amplifier, and a RF splitter. Each half of the RF circuitry also
contains its own, dedicated power regulation circuit. Two SMA connectors are provided on theLeft Side Panel as RF Outputs for use in sending RF to another RF 4 Pack or any RF receiver. TheseSMA outputs are post bandpass filter so they are RF filtered.

POWER DISTRIBUTION AND METERING
This device also contains a built in Battery Distribution System (BDS). On the left Side Panel, youwill find two Battery Input connectors. These are 4 mini Mini XLR connectors and are wired withthe pins doubled up for higher current capacity. (Pins 1 & 2 are Ground (-) and Pins 3 & 4 are
Positive (+). You can use all typical battery types and chemistries such as NP-1 batteries, “Smart”
batteries, V-Lock batteries. You can use Nickel Cadmium, Nickel metal Hydride, Lithium Ion,Lithium Iron Phosphate (LiFEPO4) or Sealed Lead Acid (SLA) batteries.
When you turn on the unit’s main power switch located on the lower left corner of the frontpanel, the unit will fully power up. There is a 4 LED, multi-color battery level meter located on
the lower right-hand corner of the front panel. This meter will indicate your battery level whenthe unit is powered up. When all four LEDs are lighted, it indicates a fully charged battery. As
the battery capacity drops, so will the lighted LEDs. Each LED indicates approximately 25% of
the battery capacity remains:

RED, YELLOW, GREEN and BLUE LEDs LIGHTED = FULL BATTERY CAPACITY
RED, YELLOW and GREEN LEDs LIGHTED, = 75% BATTERY CAPACITY
RED AND YELLOW LEDs LIGHTED = 50% BATTERY CAPACITY
RED LED ONLY LIGHTED = 25% OR LESS BATTERY CAPACITYBATTERY METER CALIBRATION:
Inside the unit is a small jumper that can be set to three different positions corresponding tothree different battery chemistries (voltages). The jumper is factory set to monitor Lithium Ion
batteries (14.8Volt nominal voltage) This setting is the most common as it is correct for most ofthe newer lithium NP-1 batteries and all of the new lithium “Smart” batteries. There are also two
other settings. One setting is for use with 12.8-volt batteries such as sealed Lead Acid (SLA) andLithium Iron Phosphate (LiFEPO4). The other setting is for use with Nickel Metal Hydridebatteries (some older NP-1s). If you want to use the non-factory standard battery monitoring,
you must remove the top cover of the unit by removing the 14 screws located on the top cover.

Once the cover is removed, you will see the battery monitor jumper. It is located near the USBpower jack on the main bottom PCB. You can then move the jumper to the position desired.
The three positions are marked on the PCB:
Position “A” =14.8V Lithium Ion (Lithium NP-1 or any “Smart” Lithium Battery)

Position “B” =13.2V Nickel metal Hydride

Position “C” =12.8V Sealed Lead Acid (SLA) or Lithium Iron Phosphate (LiFEPO4)

STEP BY STEP USE GUIDE:
1. Install your slot style receivers into the openings on the front of the PSC RF Multi SR
Four Pack noting the correct direction of the DB-25 connectors. Gently slide thereceivers into the slots until you feel the DB-25 connectors line up. Once you feel theconnectors line up, firmly press the slot receiver fully into place. Lock your receivers
into place using the screws on the receivers.
2. Connect your audio output cables from the four TA3M audio outputs or from the DB15ND connector to your mixer or recorder’s inputs. Either connector type can be usedwith either analog or AES digital signals.
3. Connect one or two batteries to the TB4M Chassis 4 pin connectors on the left side panelof the unit.

4. Connect your two receiver antennas to the RF input BNC connectors on the front panelof 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. Connect the PSC RF Multi SR Four Pack cable mounted SMA connectors to your slot
receivers using a “Criss cross” or X pattern. In some situations, it may make more sense
to keep the RF cables aligned with the receivers rather than crossed. Either way isacceptable. See photo below:

6. Power up the unit. Note that the power switch lights up green when the unit is turnedon.
*NOTES*
1.
When used with ENG “bag” mixing setups, we recommend that you remotely
mount your receive antennas up and away from your equipment. This will help
eliminate picking up of RF spray from digital recorders.
2.
Different brands of wireless receivers require their own specific brand madeadapters 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.
