Test & Measurement
TM1PLUS
OVERVIEW
The TM1PLUS is a combination kit which includes the TM1 measurement
microphone, threaded acoustic windscreen, shock mount clip, ½ inch calibrator
adaptor and microphone calibration data on CD. The data files are a numeric
representation of the TM1 frequency response. These, along with the provided
sensitivity of the microphone, can be used with a variety of popular software
measurement systems to correct the response curve of the microphone.
The TM1 is a 6 mm pre-polarized condenser microphone used for test and
measurement applications. Known for its linearity, the TM1 is very consistent and has
a particularly accurate response. The TM1Plus is not complicated to use and with the
additional supplied accessories is great value.
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 flat frequency range of 20
Hz – 25 kHz, the TM1 is an excellent tool for sound engineers, sound companies and
recording enthusiasts.
Requiring 18 - 52 V phantom power for operation, the TM1 features a precision
machined four stage brass body and capsule housing, nickel plate finish, Switchcraft®
or Audix XLR and shock absorbent O-ring.

ARCHITECT AND ENGINEER SPECIFICATIONS
The microphone shall be a back plate pre-polarized condenser with an omni-
directional polar pattern. The microphone shall operate on 18 - 52 V phantom
power and the nominal output impedance shall be equal to 200 ohms at 1 kHz.
The microphone shall have a sensitivity of 6 mV ± 3 dB / Pa at 1 kHz. The micro-
phone shall have a maximum SPL level of 130 dB with a THD of 1%. The micro-
phone 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.
OPERATION AND MAINTENANCE
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 V 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 APS2). 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. Be sure that you are plugging the microphone into a low
impedance input and that phantom power is available.
TM1PLUS
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.
FREQUENCY RESPONSE
Recording: The TM1 is extremely flat and accurate and has an excellent sound.
Because of its small profile, it can be used in conjunction with portable recording
devices for live stereo miking. The TM1 is also excellent for miking acoustic
instruments and for room ambient miking.
