Product Description:
The PSC RF Multi SR 12 Pack contains two separate, active 1 x 8 RF splitters for use with up to six
slot style receivers. This compact, rugged device was developed using the latest super low noise
RF amplifiers and will operate over an extended frequency range of 470Mhz to 700Mhz.
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 12 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. The entire unit can be powered internally from an optional
Smart battery or from a source of external DC power of 12Vdc @ approximately 1.4 Amps for
power up to six radio receivers. If additional equipment is to be powered form the power
distribution outputs, then your source of external DC power should be rated at up to 8 Amps. On
the left side of the unit there are 12 TA3M mini XLR output connectors. These provide audio
output from the three slot receivers. There are also two DB-25 connectors that are wired to the
ADAT standard and provide an additional audio output capability. In addition, there are twochassis mounted SMA connectors on the left side panel of the unit. These offer two additional
RF outputs that can be used to feed another PSC RF Multi SR 12 Pack or PSC RF Multi SR Six Packor a PSC RF Multi SMA or another radio receiver other similar device.
The PSC RF Multi 12 Pack is equipped with two mounting holes for use in mounting the Six Pack
to Sound Devices 664 and 688. These two screw holes line up with the factory screws on theSound Devices units. This allows you to mechanically secure the Six Pack to your Sound Devices
664 or 688. There are also 4 threaded mounting points on the top and bottom panels. Thesemounting points use a 6-32 thread.

Page 3Powering, Internal Battery:
The PSC RF 12 Pack is designed to be powered from most any 98 or 99 Watt hour “Smart” Battery.
These smart batteries are made by various companies such RRC and Audioroot or Inspired
Energy. The Smart Battery is held in place with a stainless-steel spring clip. To remove the Smartbattery, simply pull the battery clip toward the front of the RF 12 Pack and slide the battery out.

Powering, External DC:
The PSC RF 12 Pack is equipped with a full-size, chassis 4 pin male XLR that is used for external
powering. This connector is wired for both external powering only (no battery charging) andalso for Smart battery charging. (see next paragraph below). For operating the unit from external
power only, pins 1 and 4 are used as follows:
Pin 1 = Ground (-)
Pin 4 = Positive (+12Vdc to +16Vdc)

Smart Battery Charging:
The PSC RF 12 Pack is equipped to be able to charge the internal Smart battery. The internal
charger is set up to provide up to 4 Amps of charging current. This will fully recharge a 98 or 99
Watt/hour Smart battery in about 1.5 hours. To operate the PSC RF 12 Pack and charge theinternal Smart battery, Pins 1 and 3 are used as follows:
Pin 1 = Ground (-)
Pin 3 = Positive +19Vdc
Please note that you must use the proper rated power supply when using the charging function.
The supplied AC power supply is rated at 19Vdc ate 7.9 Amps. If you must use another power
supply, it must be rated the same at 19Vdc at 7.9 Amps or greater current.
WARNING: THE USE OF AC POWER SUPPLIES WITH A RATING OF LESS THAN 7.9 AMPS MAY
RESULT IN DAMAGE TO THE PSC RF 12 PACK WHEN CHARGING AN INTERNAL SMART BATTERYAND SAID DAMAGE WILL NOT BE COVERED UNDER WARRANTY.

Smart Battery Fuel Gauge:
The RF 12 Pack is equipped with a simple, easy to read, multi-color LED battery fuel gauge. This
LED fuel gauge is located just above the main power switch. The LED fuel gauge is multi coloredfrom RED to YELLOW to GREEN to BLUE. The various colored LEDs are also marked withapproximate percentage of remaining battery capacity.

RF Circuitry:
The PSC RF 12 Pack is equipped with two complete RF chains for proper diversity RF feeds to yourslot receivers. The two RF chains are labeled “A” and “B”. Each RF chain contains a Bias T Circuit
used to allow DC voltage to be send out of the external antenna inputs for use with powered
antennas or remote RF amplifiers. Each RF chain also includes a low pass RF filter, RF limitercircuitry, a very low noise RF amplifier, a specially designed RF bandpass filter and a proper RF
splitter.

BNC RF Inputs (Antenna Connections):
The External RF Antenna Inputs are standard BNC connectors with a 50-ohm impedance. These
BNC connectors are used to connect external antennas such as Log Periodic Arrays (shark fins)that are either passive or active, Dipole Antennas, Circular Polarized Antennas and most anyother 50 Ohm RF receive antennas. Please use high quality, 50 Ohm RF cables for best results.
RG-8 and RG-8X are highly recommended. RG-58 is only recommended for lengths up to 15 feet.

Powering Remote Antennas or Remote RF Amplifiers
The PSC RF 12 Pack is equipped to be able to power remote powered antennas or remote RF
amplifiers. The RF 12 Pack will send a DC voltage out of the two BNC RF input connectors. This
DC voltage travels along the RF antenna cable and is used by powered (active) antennas. Thereis a switch that activates this remote antenna power. It is located on the lower left side of thefront panel just to the left of the main power switch.

Page 5SMA RF Signal Loop Throughs (RF Outputs)
These two SMA connectors provide a convenient way to allow RF signals to flow out of the RF 12
Pack into another radio receiver, additional RF 12 Pack, additional RF 6 Pack or other device thatutilizes RF receiver signals (receive antenna signals)

Installing Receivers:
Installing your slot receivers is a simple operation. Make sure slot receivers are equipped with a
DB-25 connector on receivers. Depending on brand, you may also need to use a machined
adapter plate to allow the receiver to sit at the proper depth in the PSC RF 12 Pack. These include:
Lectrosonics SRB requires their SRUNI kit.
Wisycom MCR42 requires their SCK42-IK-PSC kit.
Audio Limited A10-RX must be equipped with DB25 bottom
After the receivers are fully seated into the PSC RF 12 Pack, please secure the receivers with thereceivers included M3 threaded screws. You may now connect the RF cables that feed the RF
signals into the RF receivers. The RF cables are equipped with right-angle SMA connectors.
These RF cables are normally wired in a crisscross pattern. This will insure that RF antenna “A”
feeds RF input “A” on your receivers. In some cases, it may make for a cleaner mechanical layout
to wire the RF cables without the crisscross pattern. This is a perfectly acceptable RF solution
and will work just fine.

Optional Aaton Digital Interface (Aaton Hydra System)Your PSC RF 12 Pack may be equipped with the optional Aaton Digital Interface System, (Hyrda
System). If your unit is equipped with the Aaton system, there will be a USB connector on theright-side panel of the unit marked as “AATON DIGITAL USB”. You can use this connection toconnect the PSC RF 12 Pack to your Cantar X3, your Cantar Mini or to a Laptop running various
manufactures software. With this system you can remotely control the slot receiver’s frequency
settings, monitor RF signal strength, co-ordinate frequency sweeps, etc.

DC Power Distribution:
The RF 12 Pack is equipped with a built in DC power distribution system. This allows you to powerother pieces of audio equipment from the internal Smart battery. These DC outputs are locatedon the right-side panel of the RF 12 Pack. One connector has a 4 Amp limit and the others have
2.5 Amp limits. These connectors are all individually Polyfuse protected and filtered. These
outputs have a regulated 12Vdc output that is provided by an internal DC to DC convertor. These
outputs have a maximum total DC current output of 6 Amps.

Powering Up Unit:
Powering up (ON) the unit is as simple as flipping the main power switch upward. The main
power switch is located on the left side, lower corner of the front panel. Directly above the main
power switch is the Smart battery Fuel Gauge. This fuel gauge will light up when the unit ispowered up and when there is a smart battery installed and or if the PSC AC power supply isconnected and powered up.

Audio Outputs, Mini XLR:The RF 12 Pack is equipped with 12 x Mini XLR male connectors. These connectors are locatedon the left side panel of the PSC RF 12 Pack. These connectors will output Analog Balanced audio
signals or AES Digital Audio Signals depending on your receiver’s capability and settings. Please
note that AED digital signals will only appear on the odd numbered outputs.

Mechanical Mounting Points:

Photo above shows the four (4) locations of the mounting screws

The PSC RF Multi SR 12 Pack is also equipped with four threaded mounting holes on both the top
and bottom panels. These threaded mounting holes are compatible with 6-32 screws. The screw
threaded inserts are a “blind” fastener style. That means they have a limited thread length
available and will not allow you to use a screw that is too long. This “blind” fastener threaded
insert is used so that you cannot thread in a longer than necessary screw that would damage thecircuit board inside the unit.
