Front Panel; Rear Panel; Psu 01Power Supply (Optional) - AKG PS 61 Modo De Empleo

The Power Splitter receives its supply voltages from the AC adapters that power the
receivers connected to the Power Splitter. For systems with more than four channels,
we recommend to use the optional PSU 01 power supply for up to three Power
Splitters.
Both the boosters and the Power Splitter are wideband designs for the entire VHF or
UHF range allowing you to connect receivers using different frequency sets.
Fig. 1: PS 81 front panel (identical to PS 61 front panel).
The Power Splitter front panel provides the following indicators:
POWER ON: This green LED lights to indicate the Power Splitter is powered.
BOOSTER A, BOOSTER B O.K.: These two green LEDs light to indicate the correct
supply voltage for the boosters is available at the antenna input sockets ANTENNA
A and ANTENNA B.
If the supply voltage across one of the antenna inputs is shorted or fails (drops
below 2 V), the related LED will extinguish.
IMPORTANT: The two BOOSTER O.K. LEDs do NOT indicate the status of the
related booster and therefore will not extinguish when you disconnect an antenna
cable.
BOOSTER A, BOOSTER B ERROR: These red LEDs light to indicate the booster
supply voltage across the ANTENNA A or ANTENNA B input socket is shorted or
has failed.

The PS 61/PS 81 rear panel provides the following inputs, outputs, and controls:
POWER 15 V/1A: Input jack for the optional PSU 01 external power supply.
ANTENNA A, ANTENNA B: BNC input sockets for remote receiving antennas
RA 61 B for VHF systems or RA81 B for UHF systems.
Since both the WMS 61 and the WMS 81 use diversity receivers, you will need two
receiving antennas (optional).
CABLE ATTENUATION: This three-stage slide switch (4/8/12 dB) matches the
antenna inputs (ANTENNAA and ANTENNAB) to th elength of the antenna cables.
1A to 4A: BNC output sockets for up to four SR 61 or SR 81 diversity receivers
(receiving sections A). Sockets 1A and 1B are also used for powering the Power
Splitter electronics from the receiver.
1B to 4B: BNC output sockets for up to four SR 61 or SR 81 diversity receivers
(receiving sections B). Sockets 2Aand 2B are also used for powering the booster
antennas from the receiver.
All unused outputs are electrically terminated automatically.
The PSU 01 power supply provides a secondary voltage of 15 V DC, 1 A for up to
three Power Splitters and the receivers connected to them. For details refer to the
PSU 01 Instruction Manual.
