Mode
Prior to setting up your WMS 4000, check that the transmitter and receiver are tuned to the same
frequency, referring to section 3.6 and the receiver manual.
In the display illustrations in the following sections, blinking characters are identified by angle symbols
">" and "<". All the values shown are examples of possible settings.
The " " symbol stands for a short push of the jog switch.
The " " symbol stands for a long push of the jog switch.
The " " symbol stands for turning the jog switch briefly to the left.
The " " symbol stands for turning the jog switch briefly to the right.
The " " symbol stands for turning the jog switch briefly to the left or right.
The PT 4000 bodypack transmitter has been designed primarily for use with ”L” type MicroMic Series
microphones from AKG (see section 2.4.2). If you wish to connect other microphones from AKG or other
manufacturers to the PT 4000, 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 pinout:
Pin 1: shield
Pin 2: audio (inphase)
Pin 3: audio
A positive supply voltage of 6 volts for condenser microphones is available on pin 2.
Please note that AKG cannot guarantee that the PT 4000 bodypack transmitter will work perfect-
ly with products from other manufacturers and any damage that may result from such use is not
covered by the AKG warranty scheme.
1. Plug the mini XLR connector (1) on the the cable of your microphone or on the MKG L instrument
cable (2) into the audio input connector (3) on the bodypack transmitter.
1. Open the battery compartment door (1).
2. Insert the two supplied batteries into the battery compartment, aligning the batteries with the polari-
ty symbols inside the battery compartment.
If you insert the batteries the wrong way, the transmitter will not be powered.
Alternatively to the supplied dry batteries, you may use the optional BP 4000 battery pack from AKG.
The BP 4000 fits into the battery compartment in the correct orientation only, so you cannot insert it
the wrong way.
3. Close the battery cpompertment door (1).
Never use standard rechargeable batteries! These may damage the transmitter if the charging
contacts are shorted and will provide no accurate battery capacity indication.
1. LOCK mode: The transmitter transmits the microphone output signal to the receiver. All adjustment
functions and controls except for the MUTE switch are electronically locked to prevent parameters
from being readjusted unintentionally during a performance or lecture. The LCD screen displays the
"LOCK" label.
2. SETUP mode: The transmitter transmits the microphone output signal to the receiver. All controls are
active. You can check all transmitter parameters and set the carrier frequency (refer to section 3.6) and
input gain (refer to section 3.8).
3. SILENT mode: Power to the transmitter is ON, but no RF signal is transmitted. The status LED
remains dark. You can check all transmitter parameters and set the carrier frequency (refer to
section 3.6) and input gain (refer to section 3.8).
We recommend setting the carrier frequency in SILENT mode only. This is the only way to make
sure you won't "go on air" on a frequency that is not allocated or coordinated and risk "jamming"
some other radio service or active radio mic.
Depending on the way you switch power to the transmitter ON, the transmitter will be in either LOCK
mode or SILENT mode on powering up.
If you are not sure as to what carrier frequency the transmitter is tuned to, switch the transmitter
to SILENT mode (refer to section 3.4.1 below) and check that the current carrier frequency is legal
and identical to the frequency selected on the receiver.
1. Push and hold the jog switch (6) until the backlighting of the display comes on, the message "HELLO"
appears on the display, and the status LED (1) extinguishes.
