Pt 400 Bodypack Transmitter; Muting The Microphone; Locking The On-Mute/Prg-Off Switch; Microphone Technique - AKG Acoustics WMS 400 Mode D'emploi

The PPC 1000 Polar Pattern Converter (optional accessory for the HT 400/C) will change the micro-
phone's pickup pattern from cardioid to hypercardioid. This makes the microphone even less sensitive
to sounds arriving from the sides, resulting in higher gain before feedback when you use monitor speak-
ers on stage.
Note: To install the PPC 1000, you need to remove the PB 1000 Presence Boost Adapter first.
1. Unscrew the wire-mesh cap.
2. Pull the PB 1000 off the microphone capsule, slowly rotating
the PB 1000 as you pull (a).
3. Slip the PPC 1000 on the microphone capsule to the stop,
slowly rotating the PPC 1000 as you push it home (b).
Important: When installing or removing the PPC 1000/PB 1000,
make sure to grip the capsule and rubber shock mount
(arrows) firmly with your thumb and forefinger to prevent
the capsule being severed from the shock mount.
1. Set the ON-MUTE/PRG-OFF switch (19) to "MUTE/PRG" (center position).
• If you switched from "OFF" to "MUTE/PRG":
The transmitter audio and RF sections are OFF and the status LED (20) is dark. The infrared receiv-
er section is ON. The transmitter is in setup mode and you can program the carrier frequency.
The display indicates the frequency in MHz - frequency in Preset form - "Prg IR" and changes to
alternating between the currently selected Preset and "Prg IR".
• If you switched from "ON" to "MUTE/PRG":
The microphone is muted and the status LED (20) will change from green to red. The infrared
receiver section is OFF. Since the RF section continues transmitting the carrier frequency, no
unwanted noises will become audible form the sound system.
The display alternates between the currently selected Preset and the remaining battery capacity in
hours.
2. To switch the microphone back on, set the ON-MUTE/PRG-OFF switch (19) to "ON".
The status LED (20) will change to green. The display will indicate the remaining battery capacity in
hours.
The optional Remote Mute Switch allows you to mute the transmitter if it is mounted in a position where
it is difficult or impossible to use the "on-board" MUTE switch.
1. Plug the cable (1) on the Remote Mute Switch into the REMOTE MUTE jack (2) on the transmitter.
2. Put the Remote Mute Switch in a jacket or shirt pocket or use the belt clip to clamp the Remote Mute
Switch on the belt.
3. To mute the microphone, press the button on the Remote Mute Switch. The button will lock and the
status LED will change to red.
4. To switch the microphone back on, press the button again. The status LED will change to green.
1. Plug the supplied terminal connector (3) into the REMOTE MUTE jack (2) on the bodypack transmit-
ter.
The ON-MUTE/PRG-OFF switch on the bodypack transmitter is electronically locked. You can not
mute the microphone unintentionally.
2. To unlock the ON-MUTE/PRG-OFF switch, disconnect the terminal connector (3) from the REMOTE
MUTE jack (2).
1. Fix the microphone to the H 40/1 lavalier clip or H 41/1 tiepin referring to the microphone's instruction
manual.
2. Clamp the microphone on your clothing as close as possible to your mouth.
Remember that gain-before-feedback will be the higher the smaller the distance between the micro-
phone and the mouth!
3. Make sure to aim the microphone at your mouth.
Refer to the user's manual of the respective microphone for instructions on how to use head-worn micro-
phones.
To clean the transmitter and receiver surfaces, use a soft cloth moistened with water.
