Thank you for selecting the WMS 80 wireless microphone system from AKG. Please take the time to read through this Manual. It contains information on how to make optimum use of your equip- ment. Have fun!

2. Precautions

2.1.Spill no liquids on the equipment and do not drop any objects through the ventilation slots in the equipment.

2.2.Do not place the equipment near heat sources such as radia- tors, heating ducts, or amplifiers, etc. and do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock.

2.3.Be sure to dispose of used batteries as required by local waste disposal rules. Never throw batteries into a fire (risk of explosion).

Check that the package contains all the parts listed above for your system. If anything is missing, please contact your AKG dealer.

3.3. Optional Accessories

CH 60/80 plastic carrying case for one complete WMS 80

system.

Color Coding Kit: Set of rings (for the HT 80) and platelets (for SR 80 and PT 80) in various colors for identifying the indi- vidual channels of a multichannel system.

4. SR 80 Receiver

The SR 80 is a stationary True Microcontrolled Diversity receiver for use with WMS 80 transmitters. The SR 80 operates in a sub- band up to 4 MHz wide of the 710 MHz to 861 MHz UHF carrier frequency range. The SR 80 can be switched to a maxi- mum of 15 different carrier frequencies depending on local fre- quency allocations.

3. The WMS 80 Systems

Two different WMS 80 Systems are available:

3.1.Handheld System

1 SR 80 Receiver

1 AC power adapter for 11.7 VAC

1 RMU 80 19” rack mounting kit for 2 SR 80 receivers 1 BP 80 blank panel

1 screwdriver

1 HT 80 Handheld Transmitter

2 AA size 1.5 V dry batteries

1 SA 43 stand adapter

1 adjustable protective ring for controls

3.2.Bodypack System

1 SR 80 Receiver

1 AC power adapter for 11.7 VAC

1 RMU 80 19” rack mounting kit for 2 SR 80 receivers 1 BP 80 blank panel

1 screwdriver

1 PT 80 Bodypack Transmitter

1 belt clip

2 AA size 1.5 V dry batteries

4.1.Controls

4.1.1.Front Panel

The lettering of the front panel controls is protected against scratch- ing by a protective film. To remove the film, just peel it off.

1a POWER: Switches the power to the SR 80 ON and OFF.

1b VOLUME: The VOLUME pot matches the SR 80’s output level to the input sensitivity of your mixer or amplifier.

1c SQUELCH: The squelch circuit switches the receiver off if the received signal is too weak, in order to suppress the related noise or the residual noise of the receiver while the transmitter is off. Set the SQUELCH control to minimum before first switch- ing the receiver on. (For details, refer to section 9.)

1d CHANNEL: This rotary switch selects the desired carrier fre- quency or its alternative frequencies.

1e Telescoping antennas: The SR 80 is a diversity receiver and uses two antennas in order to receive the transmitter signal at two different spots. The diversity electronics will automatically activate the antenna that delivers the better signal.

1f MUTE LED: Lights red if the squelch is active. In this case the audio output will be muted. Note that the MUTE LED does not indicate the position of the MUTE switch on the trans- mitter!

1g RF LOW/OK LEDs: Indicate the received field strength of the transmitter signal.
