2.4 PT 40 PRO
Bodypack Transmitter

You can use the PT 40 PRO bodypack transmitter with both dynamic microphones and condenser microphones operating on a supply voltage of approx. 4 V. You may also connect an electric guitar, electric bass, or remote keyboard.

The PT 40 PRO operates on a single fixed, quartz stabilized frequency in the 660 MHz to 865 MHz UHF carrier frequency range.

1 On/off switch: This slide switch provides three positions indicated in the display window:

ON: Power to the transmitter is on.

MUTE: The signal delivered by the microphone element is muted while power and the RF carrier frequency remain on.

OFF: Power to the transmitter is off.

2 Status LED: Indicates the transmitter's operating status.

LED lit green: Battery is OK.

LED lit red: From the moment the LED changes to red, the battery capacity will provide a maximum of two operating hours. We recommend replacing the battery with a new one as soon as possible.

Note:

• If you use a rechargeable battery, the LED will switch to red 15 minutes before the battery will be dead!

If the status LED (3) fails to illuminate the battery is dead. Insert a new battery.

1. To close the battery compartment, slide the battery compartment lid (1) onto the battery compartment from below to the point that the snap hook will engage.

3.2 Connecting a Microphone/Instrument (PT 40 PRO)

Fig. 4: Connecting a microphone or instrument.

Refer to fig. 4.

1. Remove the battery compartment lid (1).
2. a) Plug the mini XLR connector on the cable of your microphone into the audio input socket (2) on the bodypack transmitter.
   b) 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 (2) on the bodypack transmitter.

3 Setting Up

1. Set the on/off switch (3) to "ON" to switch power to the bodypack transmitter on.
2. Switch power to the receiver on.
3. a) Talk or sing into the microphone.
   b) Play your instrument.
4. Use the screwdriver (1a) integrated in the battery compartment lid (1) to set the GAIN control (4) to a position where the AF CLIP LED on the receiver will flash occasionally.
5. Replace the battery compartment lid (1) on the transmitter.

See also section 4.

3.3 Connecting a Microphone/Instrument (PT 40 FLEXX)

Fig. 5: Connecting a microphone or instrument to the PT 40 FLEXX bodypack.

1. Set the frequency selector (1) on the transmitter and the frequency selector on the receiver to the same positions (1 - 1, 2 - 2, or 3 - 3).

If the transmitter and receiver are tuned to different frequencies, no signal will be received!

1. Remove the battery compartment lid (1).

2. a) Plug the mini XLR connector on the cable of your microphone into the audio input socket (2) on the bodypack transmitter.
   b) 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 (2) on the bodypack transmitter.

3. Set the on/off switch (3) to "ON" to switch power to the bodypack transmitter on.

4. Set the SQUELCH control (6) on the receiver to minimum and switch power to the receiver on.
5. a) Talk or sing into the microphone.
   b) Play your instrument.
6. Use the screwdriver (1a) integrated in the battery compartment lid (1) to set the GAIN control (4) to a position where the AF CLIP LED on the receiver will flash occasionally.

3.7 Changing Carrier Frequencies (PT 40 FLEXX + SR 40 FLEXX)

3 Setting Up

1. Remove the battery compartment lid.
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.

5. Replace the battery and slide the compartment lid back in place on the transmitter.

6. 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.

7. The RF OK LED 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 will be lit.

8. PT 40 FLEXX + SR 40 FLEXX: If the received signal is noisy, set the squelch threshold to a level where the noise will stop.

9. PT 40 FLEXX + SR 40 FLEXX: Never set the squelch threshold any higher than absolutely necessary. The higher the squelch threshold (-70dB = ., -100dB = .) , the lower the sensitivity of the receiver and thus the usable range between transmitter and receiver.

In each frequency band, the spacing between the three carrier frequencies of all WMS 40 FLEXX transmitters and receivers is wide enough for operating three radio channels simultaneously with no mutual interference.

For systems with up to nine channels you will need WMS 40 FLEXX kits in up to three different frequency 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 separately.

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".
5. Set up the transmitter and receiver for channel 1.

6. Repeat steps 1 through 5 for channels 2 and 3.

7. Never operate two or more wireless channels on the same frequency at the same time and location. This would cause unwanted noise due to radio interference.

8. Prior to changing a carrier frequency, be sure to switch the transmitter off. To activate the new carrier frequency, switch the transmitter back on.

4 Microphone Technique

4.1 CK 55 L
Lavalier Microphone

Fig. 7: Positioning the CK 55 L.

1. Fix the microphone to the supplied lavalier clip or to the optional H 41/1 tiepin.

2. Clamp the microphone on your clothing as close as possible to the talker's mouth.

3. Remember that gain-before-feedback will be the higher the closer the microphone sits to the user's mouth!

4. Make sure to aim the microphone at the user's mouth.

5. Put the microphone on.

6. Bend the gooseneck so that the microphone will sit to one side in front of the corner of your mouth.

Note:

• You can adjust the microphone to conform exactly to the shape of the user's head. For details, refer to the C 555 L instruction manual which you can download from www.akg.com.
  Should you hear excessive pop noise ("p" and "t" sounds are overemphasized unnaturally), move the microphone capsule further away from your mouth (up or back).
  If the microphone sounds "thin" or flat, move the microphone capsule closer to your mouth (refer to fig. 3).
  Find the optimum position during the soundcheck.

If (for instance, in outdoor use) excessive wind or pop noise becomes audible, attach the supplied windscreen to the microphone.

1. Slide the windscreen onto the microphone capsule.
2. Pull the windscreen over the outer edge of the microphone capsule.

4.2.3 Moisture Shield

4 Microphone Technique

Fig. 8: Moisture shield on CK 55 L.

A special moisture shield on the microphone capsule makes it difficult for moisture and makeup to penetrate into the microphone. This barrier prevents the microphone sound entries from being clogged by perspiration or makeup, which would make the sound dull and reduce the sensitivity of the microphone. Therefore, never remove the moisture shield from the microphone!

In case the moisture shield is damaged or lost, the C 555 L head-worn microphone includes a replacement moisture shield.

5 Cleaning

• Use a soft cloth moistened with water to clean the surfaces of the PT40 PRO and PT 40 FLEXX transmitters.
