Freedom from the Stand is a Clip Away

Get to know them!

The Audio-Technica ATM350U restores the dignity and freedom of motion that years of sharing a microphone has robbed from your horn players. This low-profile, low-distortion condenser mic clips directly onto the bell of a trumpet, trombone, or saxophone, dramatically improving the player's output while placing them directly in the microphone's sweet spot anywhere onstage. Using the ATM350U, the sound engineer gets full control over the horn section's balance, players can take solos where they stand, and audiences get a clearer view of the stage unobstructed by stands. An integrated gooseneck provides a range of on- or off-axis placement options.

A stage condenser for any source

The ATM350 goes where other mics fear to tread — like inside the bell of a screaming trumpet or atop a rock drum kit. Even at high SPLs, this low-profile condenser microphone presents a crisp, quick, balanced sound on brass instruments, woodwinds, piano, drums, and strings. Its cardioid polar pattern reduces pickup from the rear and sides for effective feedback rejection, while its in-line 80Hz highpass filter cleans up handling noise for a cleaner mix.

Universal mount offers dependable performance

The ATM350U's clip mount clamps directly onto the bell of a horn. It tightens by hand for non-slip performance, using four rubber contact points to minimize instrument damping and sympathetic vibrations. If you're looking for consistent sound from night to night, Sweetwater recommends miking your horn with the Audio-Technica ATM350U.

Violin mount and carrying case add value

In addition to the mic and mount, the Audio-Technica ATM350U includes a hook-and-loop bridge mount for violins, along with a carrying case for protection in transit.

Audio-Technica AT350U Horn Microphone Package:

  • The clean way to mic horns onstage
  • 5" gooseneck provides a range of on- and off-axis miking options

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
