Comments about Audio-Technica AT831b Cardioid Condenser Lavalier Microphone:
I bought this microphone to use on acoustic guitar. The included sound hole mount works and the adjustment allows for some limited tonal adjustments. Audio-Technica should consider offering additional instrument mounts for this quality microphone such as the 4099G mount offered by DPA that positions the microphone over the fretboard of the guitar for more natural sound. I prototyped an alternative such mount and the results are encouraging.

Q:
Hello, thank you for your time! I am looking to bypass the belt clip preamp in order to go straight into an interface which supplies 15 volts of phantom power. Could I use a ta3f to xlr adapter and then connect to my interface with an xlr?1 answer
CUSTOMER CARE
A:
You cannot do this. The inline power module (preamp) is a necessary component. Among other things, it converts phantom power to a much lower bias voltage (around 5 V DC) to power the FET in the mic capsule. Sending 15 volts of phantom power to the capsule will destroy it.Q:
The at831b is made in china?1 answer
Q:
Hello,1 answer
Q:
Is this an omnidirectional microphone?1 answer
Q:
I need the cable to connect with a 1/4" cable to run into my amp, will this do that or otherwise how will I be able to interface with my amp?1 answer
A:
Depending on your amp, you may need an impedance transformer such as the CP8201. If your amp is looking for a LINE level signal (such as a guitar or keyboard amp), use a standard XLR cable from the AT831b power module to the CP8201, then into your LINE level input on the amp.Q:
will this work with the AT8418.1 answer
Q:
I'm having some problems with excess breathing sound coming through. I've tried having it clipped higher and lower but can't seems to get rid of it. Anything that could help this?1 answer
Q:
I need a new mic. I make a lot of software instructional YouTube videos via a screen recording app. I'm currently using an AKG C520 condenser headset mic, running through studio grade preamps and converters. However, I'm not happy with the overall tonal quality that headsets tend to provide. IMO, the sound is generally thin and compressed, partly due to the capsule and its distance and angle relationship to the mouth. Reading through your lavalier type mics it seems that the AT831b might be an excellent choice for this type of application. Would you agree, or do you recommend a different model? I record in a quiet home studio and want a hands free solution that could reasonably rival, (as far as lavaliers go), an SM7 or RE20. Thanks!1 answer
A:
The AT831b is a popular choice but as you know, sound is always subjective and I recommend trying it out and see if it will best suit your needs. Additionally, you may want an omni element such as the AT899 which again, may better suit your capturing needs. Overall tone may be adjusted in your post production but it is important to get good, clean audio into your recordings with a good sounding microphone element; which Audio-Technica is known for.Q:
I have no experience with microphones. How do I get this to work? Where does the sound go to?1 answer
Q:
Hello - I need to connect this microphone to a camcorder that uses an xlr connection. Please confirm what is the best cable to make that connection.1 answer
CUSTOMER CARE
A:
The AT831b comes with the AT8531 Power Module, which is a necessary component. That power module has an XLR output. To connect to an XLR camcorder, you would need both the AT8531 and a standard XLR cable like the AT8314.
