Q:whats the name of the U853A with a hipercardiod element?
Q:I purchased these microphones for use on the stage at my school, however I am not sure the 25' cable will be long enough to reach the sound board and hang down, do you sell extension cables?
Q:We use U853a hanging mics in our theatre for sound reinforcement of the actors. The mics are powered with phantom power from our mixer through the AT8531 power modules, at which point the Mini XLR connector on the mic cable is transitioned to a full size XLR.
A:Yes, the difference between the U853A and U853R is the power module. The U853A includes the AT8531 power module which can be phantom or battery powered while the U853R includes the AT8538 power module which is phantom powered only. The attached cable is 25'.
Q:What is the maximum distance from microphone to speaker to have a good pickup on a normal conversation?
A:Thank you for your inquiry.
Q:where do you put the battery?
A:If this is a new microphone, a single 1.5V AA battery is included with it but it is not installed. To install or replace a battery, remove the cap on the top of the provided AT8531 inline Power Module by pushing in and holding in the button on the side of the module that is marked PUSH. While holding the button in with one hand, remove the cap with the other hand. When installing the battery, note the + and - signs in the bottom of the battery compartment to aid you with the correct orientation of the battery. The negative end of the battery goes against the spring. Insert the battery at a 45 degree angle, using it to push the spring back to make room to push the positive end down into the compartment. Replace the cap, making certain that it snaps securely into place. Note that there is a 3-postion switch on the side of the module. When the switch is in the OFF position the microphone is turned off. This is true whether the mic is being battery or phantom powered at the time. When the switch is in the straight line position, the microphone is ON and the low roll-off filter is bypassed. When the switch is in the bent line position, the microphone is ON and the low roll-off filter is engaged. Low frequencies below 80 Hz are rolled off at a rate of 18 dB per octave.
Q:What are the differences between the Audio-Technica U853A and the U853R?
A:Thank you for your inquiry. The U853R is phantom power only and the U853a is phantom power or via an onboard battery. The microphone element is the same.
Q:U853A - Use on Stand?
A:Thank you for your inquiry. The AT8438 Microphone Desk-stand Adapter Mount is designed for use with this microphone. The should be no issues using this as a stand microphone.
Q:Can use 9 volt Unbalanced phantom power?
A:No it cannot.The U853A Cardioid Condenser Hanging Microphone can be powered by its associated (AT8531) power module only. The module accepts phantom power (11 to 52 V DC) through its audio output connector when phantom power is provided on a balanced 3-pin XLR microphone input connector. The module also accepts a single AA 1.5 V battery for battery powering the microphone if phantom power is not available. The power module manages phantom power by stepping it down to a much lower (less than 9 volts) bias voltage. It also balances the audio signal and sets the output impedance.
Q:Effective range for U853A
A:Microphones, like ears, can sense distance. The further away a microphone is from a source, the more distant it will sound. Adversely, the closer the microphone is, the closer it will sound. This is why there is no "range" spec for microphones.
Q:for U853A what is the effective distance from microphone to signer
A:Microphones, like ears, can sense distance. Generally speaking, you want to observe the 3:1 Rule of Microphone Placement when using a multiple microphone setup. There is also a resource about how to mic a choir on the Audio-Technica homepage (www.audio-technica.com), under "Support".
