Lawson L251, Operation Manual

Page: 8 / 11

Your Lawson Quick Change™ Capsules are fully compatible
with other Lawson microphones in the Quick Change™ series
and may be used on your Lawson tube electronics with full
multi - pattern functionality . To disconnect the head from your
tube microphone ,
first turn off the power supply and
disconnect the 7- pin cable at the mic . When disconnecting the
head from your FET electronics , there is no need to disconnect
the three - pin cable , however , it is advisable to turn down your
fader at the console . Using a Phillips head screw driver ,
remove the three stainless steel screws that are located just
below the microphone wire cloth screen . After removal of
these screws , hold the mic body with one hand and with the
other hand , pull the head / capsule section up and off ,
separating the head from the mic body . Replace with the
Lawson Quick Change™ capsule of your choice by carefully
mating the connectors . Replace the three screws into the
head . Do not overtighten these screws . Reconnect the 7- pin
cable to the microphone and turn on the power supply .
The capsule is the heart of a condenser microphone . The
integrity of the capsule , more than any other element ,
determines the microphone ' s character and quality as a
transducer . In 1927 German inventors von Braunmuhl and
Weber patented the operating principles for a new condenser
microphone capsule . In 1932 these principles were first
incorporated into the manufacture of German microphones .
Today these classic microphones are still revered and sought
after for their special sound . Lawson Microphones continues
this 60- year - plus heritage and pays homage to the genius of
those past designers and makers of timeless classics .

frequency roll - off is provided by the use of another two -
position toggle switch in the microphone base:
F = Flat / No rolloff
LC = Low Cut
The two positions of this control provide the same
characteristics as the two - position switch on the Lawson tube
mic power supply . The rolloff is designed to counter the low
frequency buildup which occurs as a result of the proximity
effect when closely miking voices / instruments . Console fader
levels should be lowered before changing rolloff settings as
loud transients may occur .
