This rotary potentiometer sets the loudness volume of the wire-  
less microphone.  
3. POWER switch  
Switches power to the WLS 8060 audio section and ampli-  
EQ  
fier ON and OFF but does not affect the charging circuit.  
The effective two-band equalizer is located in the signal path  
immediately ahead of the power amplifier and therefore acts on  
both the two microphone inputs and the LINE input.  
4. STATUS LED  
The STATUS LED will light green to indicate the unit is ON and  
the battery adequately charged. It will change to red when  
the battery is down.

2. Acceptable temperature during storage or shipping ranges  
from -15°C to +40°C.  
3. If condensation has formed on the equipment or the rear  
panel during shipping or storage, allow the unit to acclimate  
for 2 hours before powering up.  
4. The loudspeaker has been designed for use in a dry environ-  
ment with air of normal relative humidity and dust concentra-  
tion. Never expose the unit to aggressive chemical liquids or  
vapors.  
7. LINE OUT L/R  
These two RCA jacks allow you to connect either a recorder  
or another WLS 8060 to your unit using a stereo RCA cable  
(not supplied).  
The two jacks are internally paralleled and carry the output  
signal of the built-in mixer with all the volume and EQ settings  
you made. The output voltage at nominal level is 0.5 V into  
200 source impedance.  
5. You can position the unit at any angle. Make sure, though, to  
provide at least 2 inches of free air space behind the rear  
panel for adequate ventilation.  
6. Do not expose the WLS 8060 to temperatures below -15°C  
as this would cause the acid contained in the battery to freeze  
and damage the battery.  
WIRED MIC  
8. INPUT  
This balanced female XLR connector allows you to connect a  
wired microphone (optional) via a standard microphone  
cable with a male XLR connector (optional). Since the micro-  
phone INPUT provides 12 V phantom power you can  
connect both dynamic and electret or condenser micro-  
phones.  
5.2. Audio Connections  
1. Set all VOLUME controls (6), (9), and (12) to zero.  
2. Connect the desired audio source (e.g., cassette player, CD  
player) to the LINE INPUT jacks (5) using a stereo RCA cable.  
3. Use a commercial XLR cable to connect your wired micro-  
phone to the INPUT connector (8).  
4. If you want to record your performance or presentation,  
connect a (cassette, DAT, tape, or other) recorder to the  
LINE OUT jacks (7) using a stereo RCA cable.  
Input sensitivy for nominal level is 2 mV into 1 k.  
Pin 1 is ground, pin 2 ”hot” (inphase), pin 3 return.

the total discharge threshold. If this happens, recharge the battery  
immediately.  
If you cover the WLS 8060 with the optional RP 6060 rain  
cover point the antennas straight down.  
5.5. Powering Up (AC Operation)  
The WLS 8060 has been designed for an AC voltage of  
230 V/50 Hz. Custom versions with an adapter for other AC  
voltages are available on request.  
5.4. Powering Up (Battery Operation)  
The WLS 8060 has been designed primarily for battery  
operation.  
1. Plug the DC cable on the supplied AC adapter into the  
RECHARGE BATTERY jack (1) on the WLS 8060 rear panel  
(see fig. 1).  
2. Check that the AC mains voltage stated on the  
supplied AC adapter is identical to the AC mains  
voltage available where you will use your  
WLS 8060. Using the AC adapter with a different AC volt-  
age may cause irreparable damage to the unit.  
3. Connect the AC cable on the AC adapter to a convenient  
power outlet.  
Before first operating the WLS 8060 or if the unit has not  
been connected to AC power for more than a year, charge the  
battery for 18 hours.  
1. Plug the DC cable on the supplied AC adapter into the  
RECHARGE BATTERY jack (1) on the WLS 8060 rear panel  
(see fig. 1).  
2. Check that the AC mains voltage stated on the  
supplied AC adapter is identical to the AC mains  
voltage available where you will use your  
WLS 8060. Using the AC adapter with a different AC volt-  
age may cause irreparable damage to the unit.  
3. Connect the AC cable on the AC adapter to a convenient  
power outlet. Do not use switched outlets!  
Important: In case the AC plug needs to be replaced with a  
different type, note that this job may only be performed by a  
qualified technician.  
4. To power up the WLS 8060 set the POWER switch (3) to  
Charging will start automatically and the yellow Charging  
LED (2) will light constantly.  
ON.  
The STATUS LED (4) next to the POWER switch (3) will illumi-  
nate green.  
When the yellow Charging LED (2) starts flashing the battery  
is fully charged and the WLS 8060 is ready to operate.  
4. Unplug the DC cable of the AC adapter from the RECHARGE  
BATTERY jack (1).  
5. To power up the WLS 8060 set the POWER switch (3) to  
ON.  
Note: During AC operation, the charging circuit of the WLS 8060  
will automatically switch to trickle charge mode. This means  
that the battery will be automatically recharged during oper-  
ation. This also means you can continue operating the  
WLS 8060 on AC power even if the battery is completely  
down.  
The STATUS LED (4) next to the POWER switch (3) will illumi-  
nate green.  
If the STATUS LED (4) lights red the battery is down. The elec-  
tronic circuitry and the loudspeakers will switch off auto-  
matically. Recharge the battery as per steps 1 through 4.  
Note: In the event of a power failure, the WLS 8060 will auto-  
matically switch to battery operation with no interruption.  
Therefore you can not switch the WLS 8060 on and off by  
means of an external power switch or safety cut-out.  
Note: Depending on the load, battery operating time will be 10  
to 14 hours.  
Since the battery has no memory effect, you will not need to  
discharge it fully before charging. Therefore, you can start  
charging at any time irrespective of the batterys residual  
capacity.  
6. Operating Notes  
6.1. Wireless Microphone  
In order to prevent unnecessary noise, tune the transmitter and  
receiver to the same carrier frequency prior to powering up  
and inserting batteries.  
Important: Lead batteries should not be stored for extended  
periods of time in entirely or partially discharged condition.  
We therefore recommend to recharge the battery immediately  
after use.  
6.1.1. WLS 8060 Placement  
Reflections off metal parts, walls, ceilings, etc. or the shadow  
effects of musicians or other people may weaken or cancel the  
direct transmitter signal.  
In order to make sure the WLS 8060 is always ready to  
operate, it is best to leave it connected to AC power when-  
ever you do not use it.  
For best results, place the WLS 8060 as follows:  
5.4.1. Total Discharge Protection Circuit  
1. Place the WLS 8060 near the performance area (stage). Make  
sure, though, that the transmitter will never get any closer to the  
receiver than 10 ft (3 m). Optimum separation is 16 ft. (5 m).  
2. There should always be a direct line of sight between the  
transmitter and receiver.  
Discharging a battery totally may cause extensive damage. We  
therefore provided the electronic circuitry of the WLS 8060 with  
an intelligent protection circuit that effectively prevents the battery  
from being totally discharged. The protection circuit automatically  
isolates the entire WLS 8060 electronics from the battery and  
switches the loudspeakers off before battery capacity approaches  
3. Place the WLS 8060 at least 5 ft. (1.5 m) away from any big  
metal objects, walls, scaffolding, ceilings, etc.

new ones as soon as possible.  
If the status LED fails to illuminate the batteries are dead. Insert  
new batteries.  
1. Handheld Transmitter: Unscrew the battery compart-  
ment cover and the color code ring CCW.  
Bodypack transmitter: Referring to fig. 3, open the bat-  
tery compartment (3h).  
6. Handheld transmitter: Slide the supplied adjustable  
protective ring onto the shaft and screw the battery compart-  
ment cover back on. You can rotate the protective ring so that  
only the desired control will be accessible and all others  
covered.  
All controls are now accessible.  
2. Use a small screwdriver to set the CHANNEL selector on the  
handheld transmitter or on the bodypack transmitter (3f) to the  
desired channel.  
3. Set the CHANNEL selector (10) on the WLS 8060 to the  
same channel as the transmitter.  
Bodypack transmitter: Replace the battery compart-  
ment cover.  
6.1.4. Using the Transmitter  
Handheld Transmitter  
Important Note: If you set the CHANNEL selector on the trans-  
mitter to ”0”, the status LED on the transmitter will start flashing.  
This means that no signal is being transmitted.  
1. Hold the microphone perpendicularly and so that its front  
grille will be about 1 to 2 inches (2 to 5 cm) away from your  
mouth.  
6.1.3. Powering Up the Transmitter  
1. Open the battery compartment referring to fig. 2 for the hand-  
held transmitter and fig. 3 for the bodypack transmitter.  
Make sure that the end of the ribbon fixed inside the battery  
compartment of the handheld transmitter will stick out of the  
battery compartment. (The ribbon is needed for removing the  
batteries.)  
2. Talk across and slightly above the microphone front grille. This  
is the best way to avoid pop noises (overemphasis of plosive  
sounds such as ”p” and ”t”).  
3. When talking outdoors, we recommend to slip an external  
windscreen onto the microphone (see section 4.2. Optional  
Accessories).  
2. Insert the supplied batteries into the battery compartment con-  
forming to the polarity marks.  
4. Never cover the antenna with your hand. This would weaken  
the transmittee signal.  
The transmitter will not function with the batteries inserted  
incorrectly.  
Bodypack Transmitter  
3. Powering up the handheld transmitter: Set the  
PWR switch to ”I”.  
4. Powering up the bodypack transmitter: Connect  
your microphone - or instrument with MKG/L guitar cable  
(optional) - to the mini XLR socket (3d).  
For instructions on how to use the microphone, refer to the manual  
for your microphone.  
Setting Gain  
The procedure for setting gain is the same for the handheld and  
bodypack transmitters. Refer to figs. 2 and 3 above.  
Rotate the security cover (3m) CW to uncover the switches  
and set the POWER switch (3a) to “I”.  
5. Handheld and bodypack transmitters: The status  
LED will flash momentarily. If the batteries are in good con-  
dition, the status LED will continue glowing dimly.  
When the status LED illuminates brightly the batteries will be  
1. Using a small screwdriver, set the GAIN control so that the  
red status LED on the transmitter will only flash on the loudest  
signal peaks.  
15  
 
2. The red status LED on the transmitter lighting brightly means  
the transmitter is overloaded. Turn the GAIN control on the  
transmitter CCW to the point that the status LEDs will only flash  
occasionally.  
1. Make sure never to point the microphone element directly at  
the loudspeaker.  
2. Hold the handheld transmitter by the shaft. Be sure not to  
cover the microphone element with your hand.  
3. Should the loudspeaker start whistling or howling all the same  
turn the VOLUME control (9) or (12) down CCW to the point  
that the feedback noise will stop.  
MIC Switch  
Both the handheld and bodypack transmitters provide a MIC  
switch.  
In order to mute the microphone, set the MIC switch to ”0”. Power  
and carrier frequency remain ON, however. Thus, no noise will  
become audible if you mute the microphone even if the SQUELCH  
control (11) on the WLS 8060 is set to minimum (fully CCW).  
6.3. Proximity Filter  
When you talk into a microphone from a distance of less than two  
inches (5 cm), the low frequencies will be strongly emphasized.  
This so-called ”proximity effect” reduces intelligibility. The bass  
boost is higher in dynamic microphones than in condenser types.  
The WLS 8060 features a proximity filter that automatically com-  
pensates for proximity effect and ensures clear, well balanced  
speech reproduction even if you touch the microphone with your  
lips.  
6.1.5. Receiver  
SQUELCH Control  
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.  
7. Cleaning  
1. Set the SQUELCH control (11) to minimum before first switch-  
ing the WLS 8060 on (see fig. 1).  
2. If unwanted noise becomes audible, turn the SQUELCH con-  
trol (11) CW just enough to suppress the noise.  
You can clean the loudspeaker enclosure with a moistened cloth.  
To clean the transmitter surfaces, use  
moistened with methylated spirits or alcohol.  
a
soft cloth  
Important: Never set the squelch threshold higher than abso-  
lutely necessary. The higher the squelch threshold, the lower  
the sensitivity of the receiver and thus the usable range be-  
tween transmitter and receiver.  
VOLUME Control  
Use the VOLUME control (12) to set the desired loudness volume  
for the wireless microphone.  
Important: In battery operation, whenever you do not use the  
wireless microphone, set the VOLUME control (12) to zero  
and the CHANNEL selector (10) to ”OFF” in order not to  
discharge the battery prematurely.  
6.1.6. Replacing Handheld Transmitter Microphone  
Elements  
You can replace the D 880 WL1 microphone element mounted on  
the HT 80 handheld transmitter with any WMS 80 Series micro-  
phone element (D 3700 WL1, D 3800 WL1, C 5900 WL1,  
C 535 WL1):  
1. Unscrew the microphone element CCW.  
2. Screw the new microphone element CW onto the thread on  
the transmitter.  
All electrical connections will be made automatically.  
6.1.7. Interference  
Sometimes you can eliminate interference noise by shortening the  
receiving antennas one segment at a time to the point that the  
noise disappears.  
If this does not help, set both the transmitter and receiver to a dif-  
ferent carrier frequency using the CHANNEL selectors.  
6.2. Feedback  
When using your WLS 8060 with a wired or wireless micro-  
phone, acoustic feedback may occur so the loudspeaker would  
start whistling or howling. To prevent feedback,
