2 Description

2.1 Introduction

*Refer to figs. 3 and 4. See SR 4000 manual for details.

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 audience!

The PSU 4000 is a power supply with three 12 V DC outputs for powering a WMS 4000 multichannel system. 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.

2.2 Unpacking

1 PSU 4000

1 IEC power cable

3 connecting cables with DC connectors

1 19" rack mount kit

Check that the packaging contains all of the components listed above. Should anything be missing, please contact your AKG dealer.

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 provides the correct supply voltage for active components. Should the supply voltage at a DC output be shorted or fail (drop below 2V ), the output be overloaded, 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 antenna 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).

Fig. 1: Front panel controls and indicator LEDs.

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.

2.3 Controls

2.3.1 Front Panel

3 Setting Up

Fig. 2: Rear panel inputs and outputs.

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 components 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 frequency between 47Hz and 63Hz .

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.

For details on operating WMS 4000 components, refer to the appropriate manuals.

1. To power down, press ON/OFF again.

3.4 Fuse Warning!

Make sure to replace the fuse integrated in the IEC receptacle with a fuse of the same type (2 A slow-blow only. Other types of fuses may cause malfunctioning or a risk of fire.

4 Cleaning

Important!

1. Disconnect the AC adapter from the power outlet.
2. Use a cloth moistened (not wet!) with water to clean the surfaces of the equipment.

Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents since these may damage the enamel or plastic parts.
