Replacing The Color Code Clip; Setting Up The Bodypack Transmitter; Connecting A Microphone; Connecting An Instrument - AKG Acoustics WMS 40 FLEXX Mode D'emploi

• If OK (6a) is lit constantly and CLIP (6b) flashes frequently or is lit constantly, the transmitter input
gain is too high. Set GAIN (18) to "LOW".
6. Set the levels on your mixer or amplifier referring to the appropriate instruction manual, or by ear.
1. Pull the color code clip (19) off the transmitter case in the direction of the arrow.
2. Slide the supplied semitransparent replacement clip onto the transmitter to the point that it snaps into
place with an audible click.
The PT 40 FLEXX bodypack transmitter has been designed for use with the CK 55 L, C 417 L, C 420 L,
and C 444 L microphones from AKG. If you wish to connect other microphones from AKG or other man-
ufacturers to the PT 40 FLEXX, please note that you may have to rewire the existing connector of your
microphone or replace it with a 3-pin mini XLR connector.
Audio input (24) pinout:
Pin 1: shield
Pin 2: audio inphase (+)
Pin 3: supply voltage
A 4-V positive supply voltage for condenser microphones is available on pin 3.
Please note that AKG cannot guarantee that the PT 40 FLEXX bodypack transmitter will work per-
fectly with products from other manufacturers and any damage that may result from such use is
not covered by the AKG warranty scheme.
1. Set the frequency selector (25) on the transmitter and the frequency selector (8) on the receiver to the
same positions (1 - 1, 2 - 2, or 3 - 3).
2. Remove the battery compartment lid (28).
3. Plug the mini XLR connector on the cable of your microphone into the audio input socket (24) on the
bodypack transmitter.
4. Set the on/off switch (22) to "ON" to switch power to the bodypack transmitter on.
5. Set the SQUELCH control (14) on the receiver to minimum and switch power to the receiver on.
6. Talk or sing into the microphone.
7. Use the screwdriver (28a) integrated in the battery compartment lid (28) to set the GAIN control (29)
to a position where the AF CLIP LED (6b) on the receiver will flash occasionally.
8. Replace the battery compartment lid (28) on the transmitter.
1. Set the frequency selector (25) on the transmitter and the frequency selector (8) on the receiver to the
same positions (1 - 1, 2 - 2, or 3 - 3).
2. Remove the battery compartment lid (28).
3. Plug the jack plug on the MKG L guitar cable into the output jack on your instrument and the mini XLR
connector on the guitar cable into the audio input socket (24) on the bodypack transmitter.
4. Set the on/off switch (22) to "ON" to switch power to the bodypack transmitter on.
5. Set the SQUELCH control (14) on the receiver to minimum and switch power to the receiver on.
6. Play your instrument.
7. Use the screwdriver (28a) integrated in the battery compartment lid (28) to set the GAIN control (29)
to a position where the AF CLIP LED (6b) on the receiver will flash occasionally.
8. Replace the battery compartment lid (28) on the transmitter.
1. Remove the battery compartment lid (28).
2. Remove a label from the supplied sheet.
3. Letter the label as desired.
4. Remove the battery and place the label on the viewing window (28b).
5. Replace the battery and slide the compartment lid (28) back in place on the transmitter.
1. Move the transmitter around the area where you will use the system to check the area for "dead
spots", i.e., places where the field strength seems to drop and reception deteriorates.
If you find any dead spots, try to eliminate them by repositioning the receiver. If this does not help,
avoid the dead spots.
2. The RF OK LED (3a) on the receiver going out means no signal is being received or the squelch is
active.
Switch the transmitter on, move closer to the receiver, or set the squelch threshold to the point that
the green RF OK LED (3a) will be lit.
3. If the received signal is noisy, set the squelch threshold to a level where the noise will stop.
Never set the squelch threshold any higher than absolutely necessary. The higher the squelch
threshold (-70 dB = max., -100 dB = min.), the lower the sensitivity of the receiver and thus the
usable range between transmitter and receiver.
The spacing between the three carrier frequencies of each WMS 40 FLEXX is wide enough for operating
three radio channels simultaneously within the same frequency band with no mutual interference.
For systems with up to nine channels you will need WMS 40 FLEXX kits in up to three different frequen-
cy bands. Please ask your dealer which frequency bands are suited for multichannel use and approved
for the place where you will use the system. Perform steps 1 through 6 for each frequency band sepa-
rately.
1. Switch power to all transmitters and receivers off.
2. Set the frequency selectors on the transmitter and receiver for channel 1 to "1".
3. Set the frequency selectors on the transmitter and receiver for channel 2 to "2".
4. Set the frequency selectors on the transmitter and receiver for channel 3 to "3".
