about 90 minutes.
LED illuminating brightly: audio input is overloaded.
3d Audio Input : 3-pin mini XLR connector with both mic and
line level pins that automatically match the connector pinout
of the microphone or optional MKG/L guitar cable.
3e Color Code : If you use the transmitter within a multichannel
system, you may remove the black plastic platelet and re-
place it with a colored platelet included in the optional Color
Coding Kit to identify each channel by a different color.
3f CHANNEL : This rotary switch selects the desired carrier fre-
quency.
3g Belt Clip for fixing the transmitter to your belt.
3h Battery Compartment : Refer to Section 9. Setting Up.
3i Antenna : Permanently connected, flexible antenna.
3j GAIN : This rotary pot allows you to match the microphone
or instrument level to the transmitter’s audio section.
3k Carrier Frequency T able : A label listing the available
frequencies is affixed to the transmitter rear panel.
3l Frequency Set Designation : The label on the rear
panel also indicates the designation of the Frequency Set.
3m Security Cover : Protects the POWER and MIC switches
from being actuated unintentionally.
6.2. Microphones, Guitar Cable (optional)
The following AKG microphones have been designed specifically
for direct connection to the audio input of the PT 60:
C 417 L
C 419 L
C 420 L
CK 77 L
The
MKG/L
guitar cable from AKG lets you connect an electric
guitar, electric bass, or remote keyboard to the bodypack trans-
mitter.
6.3. Optional Accessories
CB 60
bag
Color Coding Kit
7. Frequencies
The transmitter and receiver of your WMS 60 system have been
factory programmed for up to 15 selectable carrier frequencies.
The carrier frequency label (1k) on the receiver, (2g) on the hand-
held transmitter, or (3k) on the bodypack transmitter lists the
Frequency Set your WMS 60 system uses and all available carrier
frequencies.
7.1. Frequency Sets
Prior to powering up your WMS 60 system, check that the trans-
mitter and receiver use the same Frequency Set. If they do not, you
may not be able to find a common carrier frequency for the trans-
mitter and receiver.
The following Frequency Sets are currently available:
Designation Frequency Countries
Range (MHz)
DK 138.25 - 142.07 Denmark
US1a (Traveler) 169.5 - 172 USA
US1b (Traveler) 169.5 - 172 USA
UK1 173.8 - 175.0 UK

EUS12 204.25 - 205.75 US12, ass’d. European*)
RS 180.25 - 181.75 Singapore
*) For frequencies allocated in the various European countries and
frequencies suited for intermodulation-free simultaneous oper-
ation, refer to the Frequency List in section 12.
7.2. Ordering Transmitters and Receivers
If you want to order additional transmitters or receivers operating
on the same set of frequencies as your original equipment, be sure
to state the designation of your original Frequency Set (1k/1l, 2i,
3k/3l) and the serial number of the original device. We need this
information to make sure your new equipment will be compatible
with the original units.
8. Multichannel Systems
Carrier frequencies allocated to wireless microphones differ from
country to country. Depending on local frequency allocations and
available carrier frequencies you can operate two to four
WMS 60 systems simultaneously. (Refer to the Frequency List in
section 12.)
In each carrier frequency table (1k, 2h, 3k), the basic frequencies
you can use simultaneously and without risk of intermodulation are
marked with *.
If you have any questions regarding allocated frequencies contact
your dealer, the competent authority, your AKG representative, or
the AKG head office in Vienna, Austria.
9. Setting Up
Prior to connecting the receiver to AC power and inserting the bat-
teries into the transmitter, set the transmitter and receiver to the
same carrier frequency. The carrier frequency tables on the trans-
mitter (2h, 3k) and receiver (1k) lists the channel number corre-
sponding to each carrier frequency.
9.1. Selecting the Carrier Frequency
1.
Handheld transmitter
: Unscrew the battery compartment
cover and the color code ring (2d or 2j) CCW.
Bodypack transmitter
: Open the battery compartment
(3h).
All controls are now accessible.
2. Use the supplied screwdriver (1q) to set the CHANNEL control
(2g) on the handheld transmitter or (3f) on the bodypack trans-
mitter to the desired channel.
3. Set the CHANNEL control (1d) on the receiver to the same
channel as the transmitter.
9.1.1. Multichannel Systems
1. Be sure to assign a separate carrier frequency to each trans-
mission channel (trans receiver).
2. Set the transmitter and receiver to one of the frequencies mark-
ed with * in the carrier frequency tables (1k, 2h, 3k).
Note:
If reception on the selected carrier frequency is disturbed,
set the
carrier frequencies for all WMS 60 channels
up or down one or two steps with the respective CHANNEL
controls (1d, 2g, 3f) on each transmitter and receiver.
This is necessary to provide the minimum frequency spacing
required for intermodulation-free multichannel operation.
Important:
Do not operate two or more WMS 60 channels on
the same frequency at the same time and location. This would
cause unwanted noise due to radio interference.
