6.2. Microphones, Guitar Cable (optional)
The following AKG microphones have been designed specifically for direct connection to the audio input of the PT 80:
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 60/80 bag
Color Coding Kit
7. Frequencies
The transmitter and receiver of your WMS 80 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 80 system uses and all available carrier frequencies.
7.1. Frequency Sets
Prior to powering up your WMS 80 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) |
|
EU58 | 770,6 - 773,4 | EU |
EU59 | 777,6 - 780,4 | EU |
EU60 | 785,6 - 788,4 | EU |
JPA | 802,5 - 805,5 | EU, Japan |
NZ1 | 812,2 - 815,0 | EU, New Zealand |
NZ2 | 833,2 - 835,0 | EU, New Zealand |
UK69A | 854,9 - 857,625 | EU, Great Britain |
UK69B | 858,2 - 860,9 | EU, Great Britain |

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 80 systems simultaneously. (Refer to the Frequency List in section 12.)
In each carrier frequency table (1k, 2h, 3k) and in the Frequency List in section 12, the basic frequencies you can use simulta- neously 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.
Alternatively, you are welcome to visit the AKG website at
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) and the Frequency List (section 12) on page 44 list the channel number corresponding to each carri - er 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 (transmitter + 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 80 channels within the same frequency set up or down one step
with the respective CHANNEL controls (1d, 2g, 3f) on each transmitter and receiver.
This is necessary to provide the minimum frequency spacing
required for
the same frequency at the same time and location. This would cause unwanted noise due to radio interference.
9.1.2. Changing Carrier Frequencies
Prior to changing a carrier frequency, be sure to switch the
