QUICKSTART GUIDE

1 Make sure that the mains voltage selection switch 4 is set to the correct position depending on the country´s specificmains electricity.
2 Use the 11-pin audio cable to connect the microphone with the 11-pin XLR socket on the backside of the PSU.
3 Use the 3-pin XLR cable to connect your mixer with the 3-pin XLR socket 5 on the backside of the PSU.
4 Put the LCT 840 into operation by activating the On/Off switch 1 on the backside of the PSU.
5 Let the tube warm up. Microphone reaches full sensitivity after 60 seconds.

7 You are ready to go!

// Operating the microphoneStatus indicator ring 10
Illuminated in white: The microphone is in normal working mode.
Illumination is off: Key-lock active.
Illumination flashes in red: The microphone is experiencing clipping due to high SPL.
Illumination in red: The microphone is in automatic attenuation mode.
Illumination flashes in white and red: The microphone indicates the clipping history.
Polar pattern indicator // 5 different directivity characteristics omnidirectional, wide cardioid, cardioid, supercardioid, figure-8
can be set by briefly turning the jog-dial to the right or left 9 .
Setting an attenuation level // Attenuation levels can be set by briefly pressing the left push button 8 .
Settings are: 0 dB, -10 dB and -20 dB. Attenuation is used in high SPL environments in order to prevent clipping of themicrophone, mixer and other audio equipment.
Setting a low-cut filter // Low-cut filters can be set by pressing the right push button 12 .
Settings are: linear, 40 Hz (12 dB/oct), 150 Hz (6 dB/oct) and 300 Hz (6 dB/oct). Low-cut filters eliminate unwanted low-frequency
sounds, compensate the proximity effect and reduce structure-borne noise. Do not forget to use the supplied windshield ifnecessary.
To learn about the key-lock function, automatic attenuation and clipping history please read the full manual following thelink at the bottom.

// Please Note// The capsule is a sensitive, high precision component. Make sure you do not drop it from high heights and avoid strong mechanicalstress and force.
// To ensure high sensitivity and best sound reproduction of the microphone, avoid exposing it to moisture, dust or extreme
temperatures. Use supplied windshield if suitable.
// Do not apply excessive force on the buttons or the connected cable.
// When disconnecting the microphone cable, grasp the connector and do not pull the cable.
// Do not attempt to modify or fix the microphone, as it would void your product warranty.
// The casing of the microphone can be cleaned easily using a wet cloth, never use alcohol or another solvent for cleaning.
// The windshield can be washed with soap water, if necessary.

// IMPORTANT NOTICE!
// Never remove the mains earth, doing so can have lethal consequences.
// Replace fuse only with the same type.
// Only use indoors, in safe and dry environments.
// There are no user-serviceable parts inside the power supply unit, but there
are potentially lethal voltages. If it does not work correctly, you should consult your dealer. Do not open the unit yourself.
// Do not disconnect the microphone cable while the system is powered as this may result in damage to the microphone.
// Do not use with damaged cables or after unit has fallen and loose parts or broken glass can be heard inside.
// Do not cover the power supply unit, always leave enough space around it for proper ventilation.
