AMT M40 overview

  • 1Description

The M40 Condenser Microphone by AMT is designed to be set inside a grand or upright piano to capture live performances with a natural and even sound. While geared for sound reinforcement, it works equally well in the recording studio or as a boundary mic for a conference or a stage.

The microphone is intended to be placed between the 2nd and 3rd sound holes on the cast-iron plate of a grand piano or fastened to the front bottom door of an upright piano. It delivers an accurate sound with a flat frequency response (20 Hz to 20 KHz) and can handle SPL up to 141 dB to capture subtle passages or thunderous fortissimos. The mono design precludes the introduction of phase issues often associated with multiple microphones, and ensures that the individual sound characteristics of each particular piano remain uncompromised.

This compact and lightweight microphone allows for a wide range of placement options. It is particularly well suited to work with the piano lid closed, removing the need for cumbersome mic stands and providing additional isolation in loud environments.

Housed in a machined-aluminum box, the AP40 preamp features Integrated Circuit technology that incorporates an interchangeable chip for multi-purpose use. It can be powered by external phantom power or 9V battery.

Handcrafted in the USA, the M40 features a durable anodized-aluminum construction to withstand high impacts and protect the unit from the rigors of stage use. It comes with a a hard shell case and a 10' audio cable that connects the mic to the preamp.

    AMT M40 reviews

    M40 Piano Condenser Microphone System is rated 4.6 out of 5 by 7.
    Rated 4 out of 5 by from Anna Moses uses it, then we can too Our piano lid is closed due to the area we are in. The Current mics we use do not work well with a closed lid. The M40 Piano Mic made a vast improvement on the sound quality coming from the piano.

    Rated 5 out of 5 by from Sounds Real For under ... I think this is the money worth spending.Easy to install and small enough to hide.
    Date published: 2009-02-08
    Rated 4 out of 5 by from I recommend AMT could include in the box a clamp to fix mic vertically
    Date published: 2011-02-09
    Rated 4 out of 5 by from A great cost-benefit Perfect for use in grand piano set in the top cover. Wide range of frequency inputs with treble and bass shines in full-bodied. We are using in our church and ing musicians and sound technicians enjoyed the performance of this microphone, so we recommend.

    Rated 5 out of 5 by from Easy to use, great sound We use this mic inside our grand piano with the cover closed. Set up is so easy - we can leave it inside and just attach the XLR cable to the external box, mounted on the dolly. And the sound is excellent - much better than the mic on a boom with the cover partly open. Because the lid is closed, there is much less unwanted sound from the rest of the band. Overall, an excellent product.

    Rated 5 out of 5 by from Amazing Piano Microphone I have used this microphone as my go to piano mic for years. I bought this one as a spare. Less expensive than most of the competition and sounds just as good or better.
    Date published: 2018-07-02
    Rated 5 out of 5 by from Great Piano Mic I've been hunting a relatively inexpensive solution for our on-stage piano and this microphone has worked wonderfully!
