Audix WSTM1 - Precision Threaded Windscreen for TM1 Measurement Microphone
The Audix WSTM1 is an indispensable technical accessory specifically designed to enhance the reliability and accuracy of audio recordings made with TM1 series test and measurement microphones. Unlike generic pressure-fit foams, this component features a threaded adjustment system, ensuring a secure and stable mechanical fit and preventing accidental slippage during critical calibration or acoustic analysis sessions.
Constructed from a high-density acoustic foam with a specific formulation, the WSTM1 acts as an effective barrier against air turbulence without compromising the linearity of the microphone's frequency response. This is vital in real-time measurement (RTA) applications, where data integrity across the entire spectrum (20 Hz - 25 kHz) is paramount. Its pop-proof and windproof design is robust enough for demanding environments, protecting the delicate 6 mm pre-polarized condenser capsule from dust, moisture, and drafts.
This accessory is not simply a protective cover; it's an acoustic engineering tool that allows sound engineers, system integrators, and acousticians to work confidently in both drafty (HVAC) indoor environments and moderate outdoor settings. By mitigating low-frequency wind noise, the WSTM1 ensures that spectrum analyzer readings accurately reflect the sound source and are not environmental artifacts.
Main features
-
Threaded mounting design: It features an internal thread that fits snugly onto the Audix TM1 and TM1 Plus microphone body, ensuring that the filter remains stationary even if the microphone is inverted or moved abruptly.
-
Acoustic transparency: Developed with materials that minimize sound coloration, allowing high frequencies to pass through with negligible attenuation, crucial for "pink noise" measurements and system tuning.
-
Capsule protection: Acts as a first line of physical defense for the microphone capsule against airborne particles, light moisture, and minor accidental bumps.
-
Durable construction: Black foam resistant to deformation and tearing, designed to withstand continuous professional use on tours and fieldwork.
-
Custom fit: Sized exactly for the geometry of Audix measurement microphones, avoiding unnecessary play or stress on the material.
Benefits for the professional
For the systems engineer or live sound technician, the Audix WSTM1 eliminates the uncertainty caused by air movement. Using this filter, you'll get more stable and cleaner readings on your real-time analyzers (RTAs), resulting in faster and more accurate system (PA) equalization. Furthermore, the secure threading means you'll never lose the filter during complex setups or in high ceilings, protecting your investment in the measurement microphone for the long haul.
Recommended use cases
-
Live sound system (PA) adjustment: Ideal for protecting the measurement microphone at outdoor festivals where wind can distort low frequencies.
-
Room acoustic analysis: Essential indoors when the microphone must be placed near air conditioning or ventilation ducts that generate turbulence.
-
Industrial measurements: Protection of equipment during environmental noise analysis in factories or open spaces.
-
Field recording: Use as a high-fidelity pop filter if using the TM1 to capture natural environments or sound effects.
Frequently Asked Questions
Does this filter work for standard vocal microphones?
No, the WSTM1 is specifically designed for the form factor and thread of Audix's TM1 series "pencil" type measurement microphones. It will not fit SM58-type handheld microphones or large-diaphragm microphones properly.
Does it affect the accuracy of high-frequency measurements?
The foam is acoustically transparent. Although any physical obstacle has a minimal theoretical impact, the WSTM1 is designed so that this impact is negligible in standard measurement contexts, prioritizing the elimination of wind noise, which is much more detrimental to the measurement.
Is it compatible with the TM1 Plus model?
Yes, it is fully compatible with both the standard Audix TM1 and the TM1 Plus version, as they share the same chassis and physical design.
Why is it threaded and not pressure-fit?
The threaded system is a professional feature that ensures the filter does not vibrate or fall off, guaranteeing a constant distance between the foam and the capsule, which is important for the consistency of repetitive measurements.
Project description
High-density acoustic foam windscreen designed specifically for test and measurement microphones. The accessory features a threaded mounting system to ensure a firm mechanical connection to the microphone body, preventing slippage. Made of acoustically transparent black material, it minimizes the influence of wind and air turbulence on the capsule without significantly altering the omnidirectional frequency response. Natively compatible with TM1 series models. Optimized dimensions and weight for balanced mounting on stands and calibrators.
