Description; Front Panel; Rear Panel - AKG PS 4000 Modo De Empleo

The PS 4000 is an antenna splitter for setting up UHF multichannel systems with up to four SR 4000
receivers per antenna splitter. (Note that the number of channels you can actually operate simultaneous-
ly depends on local frequency plans.)
The PS 4000 features two rear panel antenna inputs for connecting either SRA 1 passive antennas or SRA
2B or RA 4000 B 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 SR 4000 diversity receivers and two additional antenna outputs for feeding the antenna signal to
several additional PS 4000 antenna splitters.
The PS 4000 is housed in a 1 U, half-rack case so you can mount two antenna splitters in a single rack
space.
The PS 4000 can be powered by the included 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 of the
WMS 4000 system.
The antenna splitter front panel provides the following controls and indicators:
ON/OFF: Press this key to switch power to the unit ON. Press again to switch power to the unit OFF.
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 there-
fore will not go out when you disconnect an antenna cable.
CLA: The round plate with the AKG logo covers a bank of three DIP switches for matching the antenna
inputs (ANTENNA A IN, ANTENNA B IN) to the length of the connected cable run.
The PS 4000 rear panel provides the following inputs and outputs:
DC IN 12 V/2A: Input jack for the standard power supply or optional PSU 4000 central power supply.
ANTENNA A IN, ANTENNA B IN: BNC input connectors for SRA 1, SRA 2 B, or RA 4000 B remote anten-
nas. Since the SR 4000 is a diversity receiver 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 SR 4000 diversity receivers. All unused outputs are electrically terminated auto-
matically.
ANTENNA B OUT TO SR: The four BNC connectors 1B through 4B deliver the antenna signals for the
B inputs of up to four SR 4000 diversity receivers. All unused outputs are electrically terminated auto-
matically.
In addition to the antenna signals, outputs 1A through 4A and 1B through 4B provide a 12 VDC sup-
ply voltage for the connected SR 4000 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 antenna splitter from its standard power supply, make sure to power
each receiver from its own standard power supply, too. If you connect receivers to the antenna
splitter without connecting each receiver to a power supply and AC power, the antenna split-
ter's standard power supply may be damaged due to overload.
