Audix TM1 Omnidirectional Condenser Measurement Microphone - Studio

In this review the Audix TM1 is examined as a budget-friendly test microphone aimed at engineers and studio owners who need a reliable reference mic for room calibration and measurement work. The bottom line: the TM1 delivers a surprisingly linear frequency response and consistent omnidirectional pickup for the price, making it a practical tool for calibrating live rooms, studios and venues where accurate audio reproduction is required. Its compact brass enclosure and professional XLR connection give it a durable, no-frills build suited to repeated field use.

Key Features

• Uniform omnidirectional pattern: Provides consistent room measurements because it captures sound evenly from all angles without emphasizing any particular direction.
• Linear frequency response: Allows technicians to trust the microphone for calibration tasks where accurate tonal reproduction is essential.
• Switchcraft XLR output: Ensures a secure, pro-grade connection for use with mixers, preamps and measurement interfaces.
• 40 stage brass enclosure: Gives the microphone durable shielding and a weighty, tool-like feel that stands up to regular handling.
• Affordable test microphone: Packs measurement-grade characteristics at a lower cost than many dedicated reference microphones, lowering the barrier to entry for room calibration.

Who It's For

The TM1 is best for live sound engineers, recording studio owners and audio technicians who need an inexpensive, reliable microphone for acoustic measurements and system calibration. Its omnidirectional response and linearity make it a useful tool for measuring room modes, speaker responses and crossover checks without colouring the results.

It is less suitable for tracking vocals or detailed studio overdubs where directional control and character are desired; users seeking a multipurpose condenser for performance or creative recording should consider microphones designed specifically for those tasks rather than a measurement-focused model.

Pros & Cons

Pros

• Accurate, linear response that supports trustworthy calibration and measurement work.
• Omnidirectional polar pattern that captures room acoustics evenly for system tuning.
• Rugged brass body and Switchcraft XLR make it dependable for repeated setup and teardown.
• Good value for a dedicated test and measurement microphone at this price point.

Cons

• Not intended as a character microphone for tracking; it lacks directional control and colored tonal character.

Our Verdict

The Audix TM1 is a practical, budget-conscious choice for anyone who needs a straightforward measurement microphone with a true omnidirectional response and reliable connectivity. It is good value for acoustic calibration and live-sound tuning, offering a linear response and durable construction for routine use, but it is not a replacement for a creative studio condenser when character or directional control is required.

Frequently Asked Questions

Is the TM1 suitable for room calibration?
Yes. Its linear frequency response and omnidirectional pattern make it well suited for measuring room acoustics and speaker responses.

Does the TM1 use a standard XLR connection?
Yes. It uses a professional Switchcraft XLR output for reliable connections to mixers and measurement interfaces.

Can I use the TM1 for vocal recordings?
It is designed for measurement rather than coloured vocal tracking; it will work but lacks the directional shaping and character many vocal sessions require.
