S6000L Transmitter Set-up:
Screw the external antenna into the antenna connector on the top of the beltpack. Under no circumstances should
the length of a wire antenna be shortened, coiled up or wrapped with the audio lead as this will reduce the
performance of the radio system.
Insert the Lemo connector for the lapel microphone into the audio connector using the two red idents as a polarity
guide. Do not twist this connector. Keep the audio lead and the antenna separated at all times.
Open the battery compartment of the beltpack and insert a 1.5v ‘AA’ alkaline battery this should be inserted negative
end first, positive end toward the battery compartment door.
Switch on the beltpack using the switch on the top. The LED will light and the LCD will display the current gain setting
followed by the current loaded frequency.
• Changing the Transmitting Frequency
Next to the LCD there is a screwdriver adjust, this is actually a dual function digital switch. When the beltpack is
initially turned the LCD first shows the current gain then the current loaded frequency. For approximately 10 seconds
the decimal point will flash, during this flashing period the user can use a screwdriver to adjust the frequency. The
decimal point will then stop flashing and the screwdriver adjust can now be used to configure the gain. The operating
frequency is stored permanently in non-volatile memory so it will remain the same even if the battery is replaced.
The frequencies loaded into the transmitter can be changed through the infrared port on either the receiver front
panel, or a PALM pilot both these are described later
The exact selection of channels available will depend on how the transmitter has been programmed in the factory. It
can contain up to 64 unique channels, but your transmitter will not necessarily contain this many channels.
• Changing the gain
After the decimal point has stopped flashing the screwdriver adjust can now be used to configure the gain. The LCD
displays between 0 and 9, 0 being the minimum gain and 9 the maximum. The gain is stored permanently in nonvolatile memory so it will remain the same even if the battery is replaced
• Optimising the Gain of your system:
In order to achieve the best possible audio performance from your radio system, it is worth spending a few minutes
setting the optimum gain level.
Adjust the gain of your transmitter, as described in the appropriate section. The optimum setting for this will be found
by first adjusting the transmitter gain so that when the maximum audio signal expected just lights the receiver AF bar
display to the +3 dB. If this level is surpassed then distortion is likely. The optimum setting will vary according to who
is using the microphone and how close the microphone is placed to the mouth.
