ATM450 Cardioid Condenser Instrument Microphone

One of the new stars of the Artist Series remake, the ATM450 cardioid condenser offers an innovative side-address stick design for endless placement options and minimal obstructions. The microphone is equipped with an integral 80 Hz hi-pass filter that provides easy switching from a flat frequency response to a low-end roll-off. The ATM450 also features a switchable 10 dB pad that lowers the microphone's sensitivity, providing higher SPL capability for flexible use with a wide range of performers and system configurations. The microphone’s extended flat frequency response makes it ideal for high SPLs as well as for live and amplified acoustic instruments. Includes a professional isolation clamp to provide secure mounting, versatile positioning and effective dampening of unwanted mechanical noise.

  • Unique side-address stick design maximizes placement options with minimal obstructions

  • Uncompromising sound quality for overheads, percussion, acoustic guitar, strings and other acoustic instruments

  • Integral 80 Hz HPF switch and 10 dB pad

  • Durable performance for professional applications

  • Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source

  • Rugged, all-metal design and construction for years of trouble-free use

  • Includes isolation clamp for shock protection, secure mounting and easy positioning

Great general purpose mics These are really great general purpose mics. I use them all the time for close micing hi hats, drums, soft horns and voices. They are not great for distance micing and are much better suited for closer applications. For recording they work well and have a nice clean sound. They are not very broad so I would tend to use them as more of a fill sound and get my main source from a larger mic. December 2, 2011
The 450 has become my go to mic! I have a few of the 450s in my live sound mic case. I use them on drum OH, hi-hats, horns and various acoustic string instruments. I really appreciate the placement options with the side address. Couldn't be happier with the results that I get with the different applications. October 24, 2011

Is this a good microphone for wooden flute?

I play Irish traditional music on wooden flute. Most of my amplified playing is for dances -- ceilis, contras -- i.e., noisy environment.

I've been playing for years through the trusty old warhorse, Shure SM-57, but I'm wondering if there isn't something a bit "higher end" that might perform a bit better?

Is the ATM450 a suitable mic? Or does AT have another product in this price range that would be more suitable for mic'ing wooden flute through a PA in a noisy setting? I don't specifically need a clip-on mic, because when playing for dances, I'm mostly stationary -- and there may even be times when I may want to mic a fiddle with this mic.

Many thanks in advance for your kind advice.

Answer: 
The ATM450 will work well for Irish Traditional Flute. However, I believe a better option would be the AE5400. In my opinion, the overall sound would lend it to be a better microphone for Irish Traditional Flute than the ATM450.

Thanks!
