TEST & MEASUREMENT MICROPHONE
TM 1
Test and Measurement Microphone
TM 1
OVERVIEW:
The TM1 is a 6 mm pre-polarized condenser microphone used for test
and measurement applications. The TM1 is known for its linearity,
accurate response, consistency, ease of use and aordability.
Characterized with a uniformly controlled omni-directional polar pattern,
the TM1 is designed to capture acoustic measurements for room
analysis software programs, real time analyzers and other sound control
devices. With a at frequency range of 20 Hz – 25 kHz, the TM1 is an
excellent tool for sound engineers, sound companies, and recording
enthusiasts.
Requiring 18 - 52 Volts phantom power for operation, the TM1 features
a precision machined 4-stage brass body and capsule housing, nickel
plate nish, Switchcraft ® XLR, shock absorbent O-rings, and heavy duty
snap to t mic clip.

ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be a back plate pre-polarized condenser with an omni-directional polar
pattern. The microphone shall operate on 18 - 52 Volts phantom power and the nominal output
impedance shall be equal to 200 ohms at 1 kHz. The microphone shall have a sensitivity of 6.5
mV / Pa at 1 kHz. The microphone shall have a maximum SPL level of 130 dB with a THD of
1%. The microphone shall be machined from brass with dimensions of 19 mm diameter at the
base, 7.7 mm diameter at the top and 150 mm in length. The microphone shall be the Audix TM1.
OPERATION:
The TM1 is a low impedance microphone and should be plugged into a “mic level” input on your
console, mixer or recording device. The TM1 will NOT operate without phantom power voltage
(18 Volts minimum) which is available on most professional mic preamps and mixing devices. If
phantom power is not available on your equipment, you will have to purchase a phantom power
supply (such as the Audix APS- 2). Avoid plugging or unplugging the microphone into a PA
system unless the channel is muted or the volume of the system is turned down. Failure to do so
may result in a loud “popping” noise which could seriously damage the speakers in the PA system.
USER TIPS:
Measurement: The TM1 is an excellent choice for room analysis programs and real time analyzers.
Just be sure that you are plugging the microphone into a low impedance input and that phantom
power is available.
Ambient room application: The TM1 may be used to capture the “room sound” for in ear monitors.
Typically, you would set up one microphone on each side of the stage in a mic stand facing the
audience.
Recording: The TM1 is extremely at and accurate and has an excellent sound. Because of its
small prole, it can be used in conjunction with portable recording devices for live stereo miking.
The TM1 is also excellent for miking acoustic instruments and room ambience.

SERVICE AND WARRANTY:
This microphone is under warranty for
a period of 3 years from any and all
manufacturing defects. Should your
microphone fail in any way, please
contact the Audix Service department
at 503-682-6933. A Return Authorization number is required before returning any products.
CARE AND MAINTENANCE:
The TM1 is manufactured to exacting specs
with roadworthy construction. However, the
capsule is highly sensitive and should be
handled with care. Avoid extreme temperatures and be sure to store your microphone in
the pouch provided when not in use. Moisture
of any kind can adversely aect the sound and
performance of your microphone.
