  • Overview

    This miniature condenser microphone achieves full-sounding pickup and is known for outstanding consistency and dependable performance. Supplied with both a clothing clip and guitar mount, it provides natural and articulate vocal reproduction when used as a clip-on lavalier and excels in pickup of acoustic guitar. The PRO 70 is designed to make music and speech clearly and comfortably audible, yet never draw attention to itself or its operation. The microphone is equipped with a low-frequency roll-off switch that allows for reduced pickup of room noise. The versatile PRO 70 may be powered by either battery or phantom power. Its cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of the desired sound source.

    Great Mic + Great Price = GREAT PRODUCT


    I do Podcast interviews as well as Screen Cast. I run into a Tascam DR-40 digital recorder. Since I can inset a battery into the Pro 70, I never use the phantom power on the Tascam. The bass cut switch is great and this mic cuts my post production by 50%. I own for of these mics and if they were stolen from me, I would be on-line in a heart beat, buying four more!

    Excellent for guitar... with the AT8418 mount!


    used it on my gypsy guitar for 2 years... and just recently installed the AT8418 uniMount instead of the included 'guitar clip'. What a difference! highly recommended.. with this mount.



    Nice instrument mic for cello


    Our Cello/Classical guitar duo was our main bread and butter for some years. We've done many, many wedding ceremonies, fancy dinner parties etc as professional musicians. I've tried every piezo ceramic cello pickup made before switching my focus to mics. I decided to try the pro70 because it's billed as an instrument mic with a sound-hole clip. I built a make-shift mount to clip the mic in a good spot on the cello, and after some experimenting concluded that we had achieved adequate sound quality on the cello at long last. The pro70 brings a nice, warm, full signal into the mixing board with no unpleasant frequencies I've ever felt a need to EQ out of the mix. We've been gigging regularly with this mic for 6 or 7 years and never had a malfunction (other than low battery). We've been pretty careful with it, but it's still remarkably durable and reliable. I came to this site looking to buy 3 more so I can mic the string quartet. On a side note, I have tried to clip it on for vocals in a pinch and found it a really lousy setup for singing.

    I got the Mic but recording via zoom h4n gives low recorded


    I am not to happy with this AT-pro 70. I use this in my studio to record interviews via Zoom h4n. After the Recording is finished and imported to FCP(Final Cut Pro) for a play back the sound of the person speaking in very low. The mac volume is ste to 100%. In post I can fix that but I dont get the quality I need. So I will give it a try to a different mic.

    Great Mic


    I am a legal videographer and have used these while filming depostions for over 2 years and am VERY pleased. These are extremely durable, on a weekly basis someone drops one and none have ever broke. And I very rarely experience any interference while using these.

    Great Mic & Great Price!


    I've purchase 3 for my company and based on my experience with the mics I purchased 8 for the school I teach film at. Great tool for interviews and some on the go quick voice overs. I recommend the Pro 70 to anyone.

    Great Mic for Interviews such as Legal Depositions


    I have purchased this Mic since it came out many times over for my Legal Deposition business. You cannot come close to another mic that has this quality for this price.

  • Q & A

    Descriptions and specs say the mic and power supply are permanently attached via the cable. Spec sheet download says there's a TA3F connector: "The microphone includes a 1.8 m (6') permanently attached miniature cable. Its free end connects to the provided AT8531 power module via a TA3F-type connector. The output of the power module is a 3-pin XLRM-type connector. Which is correct? Thanks


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


    What size is the cable jack? 2.5mm or 3.5mm?


    The PRO70 allows for an XLR connection out of the included power module.


    For the application of amplifying classical guitar with clip to soundboard, and to be used in conjuction with fishman acoustic guitar amp, which pickup by Audio technica would be better, pro 70 or pro 35? Do you offer any other product that would better serve this purpose? By the way, I used a fantastic instrument clip on mic by audio technica in conjunction with Traceacoustic amp that had phantom power setting, mic was lost in the 1990s but was great for mandolin and classical guitar gigs.


    Either option would work well for your application.


    Hello, Can this mic be plugged to an iphone via some specific plug? Thank you


    Thank you for your inquiry. Yes, using a cable such as the KM-IPHONE-MICX from


    I need to order more Mic clips for this item...which ones are compatible with this Mic....Thanks


    You may find all of the compatible accessories with the PRO 70 microphone here:


    Is this compatible with ATW-R1100? Thanks


    No, the PRO70 is a wired microphone.


    Hello! I bought this microphone and it is perhaps the best wired lavalier microphone I have ever used however I have two questions: 1. I lost the battery door - can these be purchased? 2. Somehow the microphone it self, which can be unscrewed, was opened and I think something was inside the microphone which is now lost - and as such, the microphone is not working. Is there something "inside" the actual microphone portion (not the battery pack portion but the actual microphone)? Thanks!

    Mic came apart need diagram to put it together ...!!

    Can this microphone be used with my Dell laptop via a USB connection? What adapter do I need?


    Thank you for your inquiry. You would need a USB Audio Interface or XLR to USB cable. If using a cable, you will have to use a battery in the Pro 70 because most cables do not pass phantom power.


    I am considering using this to amplify my guitar for live performances. Can you use an XLR to 1/4 jack converter so it can be plugged straight into the 1/4 " jack on the P/A.or does it have to be XLR to XLR? Thanks

    You will want to make certain you are either plugging into a MIC level input or use the proper transformer, such as the CP8201 to plug into a LINE level input, such as a guitar amp.
