Audio-Technica ATM350U Microfone condensador para instrumentos

Clip-On Condenser Microphone for Stage and Studio

Built for musicians who refuse to be tied to a microphone stand, the Audio-Technica ATM350U is a clip-on condenser microphone that attaches directly to the bell of a trumpet, saxophone, or violin. This low-profile design places the capsule in the sweet spot for natural, detailed sound capture while players move freely across the stage. Sound engineers retain full control over the mix, and audiences enjoy an unobstructed view without boom stands cluttering the performance area. Engineered to handle extremely powerful dynamic sound, this microphone delivers consistent, balanced audio whether performing live or recording in the studio.

What Sets the ATM350U Apart

What makes this microphone stand out is its universal clip-on mounting system. The AT8491U mount clamps directly onto instrument bells and tightens by hand with a locking screw, using four rubber contact points to minimize damping and sympathetic vibrations. A rigid 5-inch gooseneck holds its shape once positioned, even during vigorous performance. The modular design allows the gooseneck to be swapped for longer versions or specialized mounts tailored for piano, drums, or woodwinds.

Frequency Response and Polar Pattern

A cardioid polar pattern and wide frequency response make this microphone suitable for capturing the full tonal range of acoustic instruments while rejecting feedback from stage monitors and bleed from nearby sources.

• Polar Pattern: Cardioid — focused pickup that isolates the instrument and reduces stage bleed
• Frequency Response: 40 Hz – 20,000 Hz — full-range capture from deep resonance to bright overtones
• Open Circuit Sensitivity of -49 dB (3.5 mV) re 1V at 1 PA delivers a strong output signal for clean mixing without excessive preamp gain

SPL Handling and Noise Control

Brass and percussion instruments produce extreme sound pressure levels that can overload lesser microphones. The ATM350U is built to capture these sources cleanly, with a high maximum SPL rating and a switchable highpass filter accessible via the in-line power module.

• Maximum SPL: 149 dB — handles screaming trumpets and powerful saxophones without distortion
• Switchable 80 Hz highpass filter removes handling noise, stage rumble, and low-frequency artifacts from the mix
• Impedance: 200 Ohm — compatible with standard mixing console inputs and audio interfaces

Physical Design and Mounting System

Compact capsule dimensions and lightweight construction make this microphone unobtrusive during performance. The detachable power module connects via a 4-meter cable, providing flexibility in routing signal to the mixing console or wireless transmitter.

• Capsule Dimensions: 37.8 x 12.2 mm — low-profile design that stays out of the player's way
• Microphone weight of just 14.5 g avoids affecting instrument balance during extended performances
• Cable Length: 4 m — sufficient reach from instrument to console or stage box
• Operates on 11–52 V phantom power from standard consoles and audio interfaces

Ideal for Touring Musicians and Studio Players

The ATM350U is the right choice for brass players, woodwind musicians, and string performers who need professional sound quality with the freedom to move on stage. Touring horn sections benefit from consistent capture night after night, while solo violinists gain a reliable alternative to internal pickups or stand-mounted microphones. Sound engineers appreciate the direct mounting system, which eliminates boom stands and reduces stage clutter. From jazz clubs to concert halls and houses of worship, this microphone delivers the clarity and isolation needed for a polished live mix.

Audio-Technica: Six Decades of Audio Innovation

Founded in Japan in 1962, Audio-Technica began as a manufacturer of affordable phono cartridges and has grown into a globally recognized audio equipment brand. The company released its first headphones in 1974 and gained widespread popularity among musicians with the AT4060 tube microphone. Today, the company continues to focus on well-built components at accessible prices across microphones, headphones, and turntables for both professional and consumer use.
