Studio Projects LSD 2 - Manual (Page 3)

C4 Using a male to female 3-pin XLR cable, plug microphone in to gain device (preamp, mix-
ing console, etc.) of course, all the while making sure that +48-volt phantom power is active and
gain is not at a level sufficient to cause ear-splitting feedback through monitor speakers. Address
microphone towards the grill mesh in the top of the microphone. Included with all C4 microphone
pairs are two sets of capsules: two cardioid ( the ones with the holes around the circumfer-
ence) and two omnidirectional (no holes around circumference). The threaded capsules may be
changed by simply unscrewing one capsule and screwing another on to the amplifier body. Since
the threads are delicate, take particular care not to “cross thread” the capsules during installa-
tion. It will not harm the microphone to change the capsule while still plugged in, but it will make
a horrendous noise, so it is always best to perform this operation while the mic is unplugged, or
the mic level is at minimum. If bass cut is required, select one of two featured high pass filters.
150Hz setting will attenuate low frequencies by 6dB/octave starting at 150Hz. 75Hz. Setting will
attenuate low frequencies by 6dB/octave at 75Hz. The “pad” switch reduces the signal level
between the capsule and the circuitry. Engage -10dB or -20dB pad for very high sound pressure
levels, which may otherwise overload microphone circuitry, causing distortion.
LSD2 Using the included 7-pin to dual 3-pin XLR breakout cable, plug microphone into 2-
channel gain device (preamp, mixing console, etc.), making doubly sure that +48-volt phantom
powers are active and gain is not at a level sufficient to cause ear-splitting feedback through
monitor speakers. Address microphone from side (not the top of the grill). The switches used to
control the upper capsule are located on the front of the microphone above the SP logo badge,
while the control switches for the lower capsule are found on the rear of the mic. If bass cut is
required, select 150Hz high pass filter. The “pad” setting reduces the signal level between the
capsule and the circuitry. Engage -10dB pad for very high sound pressure levels, which may
otherwise overload microphone circuitry, causing distortion. Adjust upper grill by grasping and
turning. It’s that simple! Further application information regarding the LSD2 can be found at the

TROUBLESHOOTING TIPS
No Sound Whatsoever:
All C-series microphones require external voltage in order to operate. Verify that +48-volt phan-
tom power (C1,C3,C4 & LSD2) is present. For T3, ensure that power supply is properly con-
nected and power is on.
Still No Sound (C1,C3,C4 & LSD2):
Make sure microphone cable is XLR male to XLR female and connect only to inputs labeled “Mic
In”, or “Microphone”, etc.
The Back Of My C3/T3 Sounds Different From The Front When Set To Figure Of Eight:
Are you monitoring with headphones while talking into the mic? If so, the back of the mic will
sound strange. This is because the rear diaphragm of the microphone takes the sound of your
voice and flips it 180° out of phase. Meanwhile, the lower frequency range of your voice travels
in phase along your jaw line to your ears. When the out of phase signal from the headphones
meets the in-phase signal from your ears, the two signals are phase cancelled. Since this effect
only occurs during the conditions described above, it will not affect recordings.
OPERATION
C1 Using a male to female 3-pin XLR cable, plug microphone in to gain device (preamp,
mixing console, etc.), making sure that +48-volt phantom power is active and gain is not at a
level sufficient to cause ear-splitting feedback through monitor speakers. Address microphone
from the side (not the top of the grill) above the SP logo badge. If bass cut is required, select
one of two featured high pass filters. 150Hz setting will attenuate low frequencies by 6dB/
octave starting at 150Hz. 75Hz. Setting will attenuate low frequencies by 6dB/octave at 75Hz.
The “pad” switch reduces the signal level between the capsule and the circuitry. Engage
-10dB or -20dB pad for very high sound pressure levels, which may otherwise overload micro-
phone circuitry, causing distortion.
C3 Using a male to female 3-pin XLR cable, plug microphone in to gain device (pre-
amp, mixing console, etc.), making sure that +48-volt phantom power is active and gain
is not at a level sufficient to cause ear-splitting feedback through monitor speakers.
Address microphone from the side (not the top of the grill) above the SP logo badge.
If bass cut is required, select 150Hz high pass filter. The “pad” setting reduces the sig-
nal level between the capsule and the circuitry. Engage -10dB pad for very high sound
pressure levels, which may otherwise overload microphone circuitry, causing distortion.
Use the three-way switch on the front of the C3, below the SP logo, to adjust the direc-
tional characteristics of the microphone between omnidirectional, cardioid and figure of eight:
• Omnidirectional (O-shaped nomenclature): Sound from all directions is picked up by micro-
phone without any side or rear attenuation.
• Cardioid (Heart-shaped nomenclature): Some attenuation of sound occurs on sides and rear
of microphone.
• Figure of eight: Very significant attenuation of sound pickup on sides of microphone. Front
and rear of microphone pick sound up equally, but 180° out of phase from one another.
T3 Plug power supply into ac receptacle. Connect 3-pin male to female XLR cable to output
jack on front of power supply. Use included 7-pin XLR cable to connect microphone to power
supply. Ensuring that gain device (mixing console, preamp, etc.) is not at a sufficient level to
cause ear-splitting feedback. Turn on microphone power supply. Address microphone from the
side (not the top of the grill) above the SP logo badge.
*Note – Power supply has 110v/240v switch. Ensure that switch is set to proper AC voltage for
your region. This switch is set at the factory at the time of manufacture according to region, but
a microphone purchased used, for instance, may have the incorrect voltage setting.
*Another note – The presence of or lack of +48- volt phantom power will not affect operation
of T3.
