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.
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).
6.1.5. 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.
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.
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,
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.
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.
7. Cleaning
You can clean the loudspeaker enclosure with a moistened cloth.
To clean the transmitter surfaces, use a soft cloth
moistened with methylated spirits or alcohol.
