Use a standard 3- pin XLR mic cable between the FET
microphone and the console microphone input with 48 volt
phantom . The FET only requires 20 to 30 dB of mic preamp
gain at the console with close - up vocals . To insure lowest
distortion , set the gain of the console mic preamp , and
monitor the console meters BEFORE the insertion of any
outboard limiters , equalizers , etc .
10 dB /20 dB Pad A 10 or 20 dB reduction in sensitivity can be
achieved with the miniature three - position toggle switch
located in the microphone base:
Center = no attenuation
10 = -10 dB
20 = -20 dB
The -10 and -20 dB positions help to insure low distortion
operation when miking instruments of very high sound
pressure levels . To maintain lowest noise , use pads only when
miking high sound pressure levels . Console fader levels should
be lowered before changing pad settings as loud transients
may occur .

How to Replace the Fuse Disconnect the power supply from
the electrical outlet . The fuse holder is located on the rear of
the power supply unit just above the AC power connector . To
replace the fuse , pull the fuse retainer cap with a screwdriver .
Examine the 1/2 amp (500 mA ) fuse visually or with an
electrical continuity tester . Replace the fuse , if necessary . ( A
spare fuse is included in the retainer cap .) Insert the new fuse
into the fuse retainer cap . Insert the cap and fuse into the
holder by pushing straight in . If the unit continues to blow
fuses , refer the unit to a competent service technician . Do not
attempt repairs yourself as potentially dangerous voltages are
present within the power supply and unauthorized repairs
during the warranty period may void the warranty .
