Comments about Audio-Technica AT831R Cardioid Condenser Lavalier Microphone:
This is our standard for lavaliers for worship and conferences and has been for over 18 years. AT is very reasonable when providing non-warranty service, unlike the competition who charge way too much.

Q:
Is it possible to wire this to a 4 pin HRS and use with AT wireless transmitters (like the AT831cw)? Aren't they the same mic? If so, what would the connections be?1 answer
Q:
I bought this and lost the instrument clip am I able to buy a replacement for it?1 answer
A:
Yes, the AT8444 Guitar Adapter is available through an Authorized Audio-Technica Dealer.Q:
Is there any chance to have it work on battery like at831b?1 answer
A:
Yes, the only difference between the AT831R and the AT831b is the power module that is included. The AT831b includes the AT8531 power module that can allow the microphone to be powered via battery or phantom power.Q:
What is the appropriate power supply?2 answers
A:
The AT831R comes standard with the AT8538 power module and you may power the microphone via any standard +48v phantom power supply. This may be via the device you are connecting the microphone to or you may use an external supply such as the AT8801.A:
48v supplied on the XLR mic input on a Mixer is fine. Can you plug ithe mic directly into it, as in by-pass the provided AT8538 inline power module? No, you cannot. The power module is not a power SUPPLY. The module requires phantom power to work. Part of what the module does is it buffers (or steps down) phantom power to a much lower bias voltage to power the FET in the microphone capsule. This is typically somewhere between 1.5 and 5 volts. Sending 48 volts directly to the capsule would destroy it.Q:
p/n for 831 (new style) clothing clip?1 answer
A:
The AT8419 is the clip that pivots. Another clip to check out is the AT8414. To view either of these products, please visit www.audio-technica.com for more info. Additionally, there is an Authorized Dealer Locator on the A-T homepage.
