  • Overview

    Designed for use with brass, saxophone and other instruments, the ATM350U UniMount® mounting system gives you the tools to perform with confidence. The system features the ATM350a cardioid condenser microphone, a high-SPL mic that provides a clear, well-balanced response from any instrument. When teamed with the included AT8491U universal clip-on mount and strong, flexible AT8490 5" gooseneck, the mic can be clipped securely to the bell of your instrument and positioned to stay where you want it – the gooseneck won’t flop around no matter how aggressively you move the instrument as you play.

    The microphone’s cardioid polar pattern isolates the instrument by reducing side and rear pickup, and the switchable 80 Hz high-pass filter on the in-line power module helps control undesired low-frequency noise. The system also includes an AT8468 violin mount with hook-and-loop fastener and a protective carrying case.

    Hello Im interested to buy the atm350a But i need it for a specific instrument wich i didnt find a way to mont it on. My instrument is the Oud. The shape of the oud is similer to the western instrument the lute. Any solution ? :)


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    I need to know what clip and mic model number to get for a acoustic bass


    Thank you for your inquiry. Please contact our Audio Solutions Team at 330-686-2600 ext. 5000. They would be happy to help you.


    Hello, I am a saxophone player. I ask about differences between "U" and "UL" model, thanks


    The "U" indicates the Universal Mount and the standard 5" gooseneck length whereas the "L" indicates the longer 9" gooseneck length.


    Does this ATM350U system include an Attached Preamplifier? If so, how long is the cord between the mic and the pre-amp? Does the system require Phantom Power?


    No, the AT8543 power module is included and requires phantom power to operate. You may find additional helpful information here: Depending on the model, the cable lengths between the microphone element and the power module differ. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    I currently use an ATM350 (discontinued) clipped to my violin chin rest. Is the ATM350a going to be any more feedback-resistant, directional, or bleed-over-resistant than the ATM350? Does the higher SPL of the ATM350a affect any of these characterics or make it better suited for a loud live bluegrass (w/ drums) setting if mounted like my current ATM350?


    The capsule is very similar in performance to its predecessor.


    Hello, Can this mic be purchased with a connection for a Shure UR1 belt-pack wireless transmitter? I would like to use this as a microphone for a solo violin performance with a backing band. I need to be able to move around similar to a lead singer would.


    No, the ATM350U microphones are available in a wired connection and a wireless connection for Audio-Technica UniPak transmitters.


    Good evening, Pretty easy question about the ATM350U- does it connect to a regular XLR mic cable or is it only wireless - I want to use this with an Acoustic Archtop guitar Thanks Joe


    The connection will be a standard XLR connection. You may use the ATM350UCW which will allow the connection to an Audio-Technica UniPak wireless transmitter.
