FEATURES
The TCM 1150 is the best value available today in studio tube condenser microphones–with the classic vintage look and the
same extraordinary sound and performance of a legendary vacuum tube microphone, at a fraction of their original cost. For
the first time, the superior technology of these classic microphones is affordable even to the most modest project studios. With
the superior rugged construction and unparalleled warmth, presence, and clarity of the original classics–but with unbeatable
affordability—the TCM 1150 studio vacuum tube condenser microphone delivers both superb sound and unsurpassed value.
• Ideal for the most demanding applications, including all
forms of vocal and instrument pickup
• Gold-sputtered, ultra-thin (1” diameter) mylar dual
diaphragm
• Tube preamplifier circuitry with 6072 vacuum tube (a
classic 12AT7 specially selected for low distortion, superior
signal-to-noise ratio and minimum sensitivity to mechanical
vibrations)
• Special output transformer designed for ultra transparency
and natural warm reproduction of sound
• Almost all brass parts for years of studio workhorse
reliability
• Power provided by a dedicated AC power supply with a
balanced XLR output for connection to any mixing console,
with no phantom power required
• Nine different polar patterns remotely selectable on power
supply for ultimate versatility in use and ease of operation:
omnidirectional, cardioid, figure 8, and six intermediate
stages
OPERATION
The TCM 1150 must be powered by the supplied TMPS-2 power supply and amplified by a microphone pre-amp (such as
built into a mixer, or a stand-alone unit).

USING THE MICROPHONE SHOCK MOUNT
It is recommended that the TCM 1150 be used with the
SSM-1150 spider shock mount, which uses an elastic
suspension to isolate the microphone from vibration, thereby
lowering noise transmitted to the microphone from the stand.
This is a useful tool in many situations, such as when the
performer is tapping his or her feet, or when there is noise
pickup from the rumbling of traffic outside of the building.
The disadvantage of using the shock mount is that the weight
of the microphone may make it drift in the elastic suspension,
so mic placement may take a little longer.
To insert the TCM 1150 into the SSM-1150 shock mount,
pinch close the levers on the sides of the mount to the open
position, then slide the microphone into place.
USING THE FOAM WINDSCREEN
The FW-1150 foam windscreen is supplied with the
TCM 1150. This windscreen fits over the grill portion of the
microphone and is designed primarily to decrease bass
rumble (from wind noise pickup) during outdoor live or
recording use. It is also useful in keeping mouth spray out of
the microphone head. The windscreen should be used
whenever someone is close miked to both protect the
microphone and to also eliminate “popping” sounds from
percussive breath sounds. An external stand mount pop filter,
such as the Nady MPF-6, is also ideal for this application.
(Note: Be aware that the foam windscreen will slightly
attenuate the high frequency response of the microphone.)
(WARNING: The capsule is the heart of the condenser
microphone. If it becomes dirty or wet, the sound will be
degraded. Never spray any liquid on the microphone head.
Always use a foam windscreen or pop filter if you talk or sing
close to the microphone grill screen.)
