PRODUCT DESCRIPTION:
The PSC Active RF Matrix Rack is used to combine up to four (4) RF “Zones” and then distribute
the RF signals to your wireless receivers. This device offers four sets of two BNC RF input
connectors for ease of use in interfacing with your external antennas. Each of the four diversity
BNC input connector pairs can be used for individual RF “Zones” and can be routed to the RF
matrix using the front panel switches. In addition, each of the four diversity RF input pairs has aseparate remote antenna power function available. This switchable power source can be used
to power external powered antennas or remote line amplifiers.
There are five front panel mounted toggle switches on the unit. One is marked “MAIN POWER”
and this controls the overall power to the unit. The remaining four toggle switches are marked
as RF Zone 1, RF Zone 2, RF Zone 3, and RF Zone 4. Each of these four switches has three (3)possible settings. Each switch controls one of the four diversity RF input pairs. In the “DOWN”
position, that individual diversity RF input pair is routed to the RF matrix for distribution to all
your wireless receivers. In the CENTER position, that diversity RF input pair in switched off andis not routed to the RF matrix. In the “UP” position, that individual diversity RF input pair inrouted to the RF matrix and has the remote antenna power turned on for feeding remote
powered antennas or remote RF amplifiers. All four (4) of the switches are accompanied by panel
mount LEDs for easy operation. Just to the right side of the switch monitoring LEDs is a RED LED
that will light up if no diversity RF input pair has been selected. This provides a warning to theoperator that no RF inputs have been selected.
Please note that you can use any combination of one or more of the four RF Input zones to feed
your wireless receivers. For example, you can use Zone1 1 only or Zone 2 only or Zone 3 only or
Zone 4 only or any combination of multiple zones up to and including all four RF zones.
Toward the right side of the front panel, you will find RF signal strength meters for your use inhelping determining overall RF signal strength that is being sent out to your RF receivers. These
RF meters are useful for in-field RF trouble shooting.
To the farthest right side of the front panel, you will find the main power switch with RED power
on indicating LED.
The entire unit is powered from any source of external DC power of 12Vdc at up to a maximumof approximately 800mA 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 four (4) sets of diversity RF input pair BNC connectors and sixteen(16) diversity RF output pairs of SMA connectors. These 32 SMA connectors provide RF output
from the unit to feed up to 16 diversity receivers.

RF INPUT ZONE ASSIGNMENTS AND REMOTE ANTENNA POWER:
Each of the four (4) RF input zones can be independly selected and added to the RF signal thatwill be sent to your receivers. Each of these four diversity input pairs can be operated with orwithout remote antenna power being sent to your powered antennas or remote RF amplifiers.
Please see the examples on the next page for a detailed explanation:

Please note that the GREEN LED indicated that the RF Input Zone has been selected and the
YELLOW LED indicates that Remote Antenna Power has been applied to that RF input diversity
pair (input Zone). Please also note that these same GREEN and YELLOW LEDs are also used onthe rear panel of the unit located right next to each RF input BNC connector for yourconvenieance.

RF METERING:

RF Signal Level Meters

There are two RF signal level meters on the front panel of the PSC Active RF Matrix. These
meters monitor the RF signal strength of the RF that is going out of the unit via the SMA
connectors to your wireless receivers. They display signal levels form approximatey -56dB up
to +10dB. They can be used for overall RF signal monitoring while in normal use or for RF signal
level monitoring while doing site setups. For example, if you are want to test the RF signal
strength of your various RF Zones before production starts for the day, you can switch on onlythat one particular RF zone and then use the meters to monitor that one RF zone. You canrepeat this quick test for any and all other used zones, one zone at a time.

EXTERNAL POWER:
This unit can be powered from AC Line Voltage (90 to 240Vac) or from low voltage DC such asrechargeable batteries, DC power supplies or other sources. The DC input has a voltage rangeof 10 to 18Vdc. The unit draws approximately 800mA of current @ 12Vdc with no active
antennas powered up. When operated with the maximum of eight (8) active, powered
antennas, the unit will draw approximately 2 Amps @12Vdc.

RF CIRCUITY DECRIPTION:
Your new PSC Active RF Matrix Rack contains RF distribution designed to provide proper, clean
RF distribution to your receivers. Each of the four (4) diversity RF inputs contains a built in DC
bias circuit designed to be able to power external remote powered antennas and/or remote RF
amplifiers and also super high quality RF switches that allow those individual RF input pairs to be
assigned or not assigned to the RF mix. These high-quality RF switches provide more than 50dB
of RF isolation when switched off. Each diversity RF section is summed using high quality RF
combiners with typical rejection ratios of better than 27dB. An RF bandpass filter (various
frequency ranges available) follows the RF combiner and is then followed by an RF limiter to help
guard against RF overload. Two, very low noise, high current RF Amplifiers, and two RF splitters.
Are used to feed the 16 SMA RF outputs. Each part of the RF circuitry also contains its own,
dedicated power regulation circuit for better RF cross talk specifications. The circuit boards usedin this product are special, 4-layer RF PCBs for maximum performance.

STEP BY STEP USE GUIDE:
1. Install your PSC Active RF Matrix Rack into your Sound cart using the rack brackets
included with each unit. Please note that these rack rail brackets are reversable fromfront of unit to back of unit and can be installed with the rack unit flush to the rack faceor recessed simply by changing the screw rack mounting bracket screw locations.
Alternatively, you can use Velcro to mount the unit to a shelf on your sound cart if it is
not equipped with rack rails.
2. Connect your remote antenna cables to the various diversity input pairs using the BNC
connectors and high-quality RF cables. We recommend that you use RG-8/X cable forcable lengths up to about 25 feet (8 meters). We recommend that you use RG-8 cablefor lengths over 25 feet. When using remote, powered antennas or remote line
amplifiers, make sure to flip the RF input switch on the front panel to the “UP” position.
You can verify that that individual BNC RF antenna input has remote power applied to
it by seeing the Yellow LED lit up next the BNC connector. “Antenna” power switch. If
you are not using remote powered antennas or remote RF amplifiers, flip the switch to
the “down” position so that no remote antenna power is applied to your RF input
cables.
3. Connect either a 12 VDC power source to the 4 pin XLR external power connector orconnect the unit to AC power using the AC power receptacle.
4. Connect up to 16 diversity receivers by connecting short RF interconnect cables fromthe SMA outputs of the PSC Active RF Matrix to the SMA or BNC RF inputs on yourspecific receivers. Typically, these RF interconnect cables are less than 2 feet (0.6meter)long and can thus be made with various small diameter RF cable if desired as the loss
through these short cables is negligible. We typically suggest using RG-58, RG-8/X or
the smaller RF cables such as RG-174 or RG-316.
5. Power up the unit. Note that the power switch lights up RED when the unit is turnedon.
6. Select your diversity RF input pairs of antennas based on your particular circumstances.
For example, the actors are only in “Zone 1”, so only turn on “Zone 1”. If the actors arein Zones 1, 3 and 4, then turn on Zones 1, 3 and 4.
