The PS 4000 W is an antenna splitter for setting up UHF multichannel systems with up to four receivers per antenna splitter. (Note
that the number of channels you can actually operate simultaneously depends on local frequency plans.)
The PS 4000 W features two rear panel antenna inputs for connecting SRA 2 B/W or RA 4000 B/W active antennas with built-in
boosters. Each antenna input provides a 12 VDC supply voltage for powering up to three active antenna components, e.g., one active
antenna and two AB 4000 antenna boosters. Also located on the rear panel are two sets of four antenna output connectors for up
to four diversity receivers and two additional antenna outputs for feeding the antenna signal to several additional PS 4000 W anten-
na splitters.
The PS 4000 W is housed in a 1 U, half-rack case so you can mount two antenna splitters in a single rack space.
The PS 4000 W can be powered from an optional local power supply. For systems with more than four channels, we recommend using
an optional PSU 4000 central power supply for three antenna splitters each.
Both the antenna boosters and the antenna splitter are wideband devices for the entire UHF band.
The antenna splitter front panel provides the following controls and indicators:
ANTENNA A, ANTENNA B: The blue OK LED will be lit for as long as the ANTENNA A IN/ANTENNA B IN input provides the correct
supply voltage for active components.
Should the supply voltage at an input be shorted or fail (drop below 2 V) the OK LED for that input will extinguish and the red
ERROR LED be lit instead.
• The two OK LEDs do NOT indicate the operating status of the connected antenna booster and therefore will not go out when you
disconnect an antenna cable.
CLA (Cable Length Adjustment): The round plate with the AKG logo covers a bank of three DIP switches for matching the anten-
na inputs (ANTENNA A IN, ANTENNA B IN) to the length of the connected cable run.
The PS 4000 W rear panel provides the following inputs and outputs:
DC IN 12 V/2A: Input jack for an optional 12 VDC power supply or optional PSU 4000 central power supply.
ANTENNA A IN, ANTENNA B IN: BNC input connectors for SRA 2 B/W, or RA 4000 B/W remote antennas. When using diversity
receivers you will need two receiving antennas (optional). Each antenna input provides a 12 VDC supply voltage for an active
antenna.
ANTENNA A OUT TO SR: The four BNC connectors 1A through 4A deliver the antenna signals for the A inputs of up to four diversi-
ty receivers. All unused outputs are electrically terminated automatically.
ANTENNA B OUT TO SR: The four BNC connectors 1B through 4B deliver the antenna signals for the B inputs of up to four diver-
sity receivers. All unused outputs are electrically terminated automatically.
In addition to the antenna signals, outputs 1A through 4A and 1B through 4B provide a 12 VDC supply voltage for the connect-
ed receivers.
• The only way to ensure that outputs 1A through 4B/Will provide sufficient current to power the connected receivers is
to connect the antenna splitter to an optional PSU 4000 central power supply.
• If you power the PS 4000 W antenna splitter from an optional local power supply, make sure to power each receiver
from a local (optional) power supply, too. If you connect receivers to the antenna splitter without connecting each
receiver to a power supply and AC power, the antenna splitter's standard power supply may be damaged due to over-
load.
LINK A TO PS, LINK B TO PS: These two BNC outputs carry the RF signal of the two antennas A and B. You can connect the LINK
outputs to the antenna inputs of another PS 4000 W antenna splitter to daisy-chain several antenna splitters.
Note that you will need one optional PSU 4000 central power supply each to power three PS 4000 W antenna splitters.
