2.1 Introduction
*Refer to figs. 3 and 4. See
SR 4000 manual for details.
2.2 Unpacking
6PSU 4000
1. Do not spill any liquids on the equipment and do not drop any objects through the ventilation slots in
the equipment.
2. The equipment may be used in dry rooms only.
3. The equipment may be opened, serviced, and repaired by authorized personnel only. the equipment
contains no user-serviceable parts.
4. Before connecting the equipment to power, check that the AC mains voltage stated on the equipment
is identical to the AC mains voltage available where you will use the equipment.
5. To avoid the risk of electric shock, make sure to connect the equipment to a grounded power outlet.
It is illegal to disconnect the protective ground wire or use a non-standard power plug.
6. Prior to connecting receivers to the equipment, compare the output voltage of the equipment with the
operating voltages of all receivers. Only connect receivers operating on the same voltage, type of
current (AC or DC), and having the same connector polarity as the outputs on the PSU 4000.
7. The current drain on the DC OUT 1 output of the equipment must never exceed 2.5 A, the current
drain on outputs DC OUT 2 and DC OUT 3 must never exceed 2 A.
8. Never short any of the equipment's outputs!
9. Never apply any voltage to any of the equipment's outputs. Never connect any type of power supply
to a PSU 4000 output. This may cause damage to both the equipment and the power supply.
10.If any solid object or liquid penetrates into the equipment, shut down the sound system immediately.
Disconnect the power cable from the power outlet immediately and have the equipment checked by
AKG service personnel.
11.If you will not use the equipment for a long period of time, disconnect the power cable from the power
outlet. Please note that the equipment will not be fully isolated from power when you set the on/off
switch to OFF.
12.Do not place the equipment near heat sources such as radiators, heating ducts, or amplifiers, etc. and
do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock.
13.To avoid hum or interference, route all cables away from high-voltage lines of any type.
14.Clean the equipment with a moistened (not wet) cloth only. Be sure to disconnect the power cable
from the power outlet before cleaning the equipment! Never use caustic or scouring cleaners or clean-
ing agents containing alcohol or solvents since these may damage the enamel and plastic parts.
15.When routing cables, make sure that nobody can trip over them.
16.Do not use any accessories except those recommended by AKG.
17.Do not use the equipment for any applications other than those described in this manual. AKG can-
not accept any liability for damages resulting from improper handling or misuse.
1. When scrapping the equipment, separate the case, circuit boards, and cables, and dispose of all com-
ponents in accordance with local waste disposal rules.
2. The packaging of the equipment is recyclabe. To dispose of the packaging, make sure to use a col-
lection/recycling system provided for that purpose and observe local legislation relating to waste dis-
posal and recycling.
Thank you for purchasing an AKG product. This Manual contains important instructions for setting up and
operating your equipment. Please take a few minutes to read the instructions below carefully before
operating the equipment. Please keep the Manual for future reference. Have fun and impress your audi-
ence!
The PSU 4000 is a power supply with three 12 V DC outputs for powering a WMS 4000 multichannel sys-
tem. The unit features a 1-U 19" case for rack mounting*.
The PSU 4000 replaces the AC adapters that come with the various WMS 4000 components and thus
greatly simplifies the setting up of multichannel wireless systems.
Check that the packaging contains all of the components listed above. Should anything be missing,
please contact your AKG dealer.

3.2 Connecting to Power
Warning!
The power supply 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.
DC OUT 1 - 3: The blue OK LED will be lit for as long as the assigned DC output DC OUT 1, 2, or 3 pro-
vides the correct supply voltage for active components.
Should the supply voltage at a DC output be shorted or fail (drop below 2 V), the output be over-
loaded, or the temperature of the unit exceed the acceptable level, the OK LED for that input will
extinguish and the red FAIL LED be lit instead.
The PSU 4000 rear panel provides the following inputs and outputs:
IEC receptacle accepting the matching connector on the supplied power cable. The IEC receptacle
incorporates a standard fuse holder with a 2 A slow-blow fuse. The PSU 4000 uses a wide-range
power transformer for primary voltages from 90 VAC to 264 VAC.
DC OUT 1: DC output jack with a load capacity of up to 2.5 A for connecting a PS 4000 with an anten-
na system and up to four SR 4000 receivers (the receivers are powered via the antenna cables) or
one other WMS 4000 component (HUB 4000, HPA 4000, CU 4000).
DC OUT 2, DC OUT 3: DC output jacks with a load capacity of up to 2 A for connecting a WMS 4000
component (SR 4000, HUB 4000, HPA 4000, CU 4000, PS 4000 with no antenna system).
Make sure the total current consumption of all components connected to DC OUT 1 does
not exceed 2.5 A and the total current consumption of all components connected to DC
OUT 2 or DC OUT 3 does not exceed 2 A. Higher loads can cause damage to the PSU 4000
due to overheating.
Do not connect the unit to power before you have made all audio and DC connections.
Check that the output voltage of the PSU 4000 is identical to the operating voltage of the
components your about to connect. Operating components on an incorrect voltage may
damage both the compponents and the PSU 4000.
1. Use the supplied connecting cables to connect the DC OUT jacks on the rear panel of the PSU 4000
to the DC input jacks on the desired components.
2. Each connecting cable has a ferrite core attached near one end. Make sure to connect this end of
each cable to the PSU 4000.
Never plug a connecting cable into an unused DC OUT jack. The unused DC connector on
the cable may be shorted by metal parts.
The PSU 4000 features a wide-range power transformer for primary voltages from 90 VAC to 264 VAC.
Therefore, you can connect the unit to any power outlet with an AC voltage within this range and a fre-
quency between 47 Hz and 63 Hz.
1. Use the supplied power cable to connect the PSU 4000 to a convenient power outlet.
To avoid the risk of electric shock, make sure to connect the equipment to a grounded
power outlet.
