  • Overview


    Maintaining the Audio-Technica tradition of clear and transparent sound quality, the U853A cardioid condenser hanging microphone is ideal for speech, theater, orchestra and choir sound reinforcement and recording. The microphone’s fast transient response and low distortion characteristics allow every complex detail to be heard with all its impact—rich, vibrant qualities faithfully reproduced. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U853A accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. The battery- or phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

    • Q:

      where do you put the battery?

      is there a battery already in it, and if not, how to I put the battery in? If there is a battery, then how do I replace it?
      Asked on 11/16/2014 by Gina

      1 answer

      • 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?
      Asked on 5/10/2013 by stambo

      1 answer

      • 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?

      We no longer have use for it to be hanging where it is. We would rather be able to be mobile with it. Are there stands that could work with them? What dangers should we be looking for it we do put them on stands?

        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?

      What pin is phantom power on?
      Asked on 10/16/2012 by Craigo

      1 answer

      • 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

      Thank you for the prompt answer. Sorry I am not experienced so I still need more explanation, please bear with me. (1) distance based on 1:3 ratio. But what is the effective range for the 1 (in 1:3 raio). Let me ask in a stupid way,can we hang the microphone 30 feet from the first signer ? I think not, so what is the recommended range from the microphone to the first signer, 5 feet to 10 feet, or 5 feet to 30 feet ?
      For the 2nd question, bent or straight setting choice ? what is the intended application, hanging or on the microphone stand ? Can you provide some guidelines, or we just try and see ?

      For the 3rd question, that is a good suggestion. But if we use regular XLR cable to extend the distance, the power module will be located on the ceiling which is very difficult to access, and we need to access to turn on and off the switch, to replace battery. So my question is whether there is way to extend the 25" cable, which come with the microphone.
      Asked on 9/24/2012 by bwav

      1 answer

      • 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.

        The bent switch engages the low-end roll-off. This attenuates some of the low frequencies, but not all. The straight line is normal frequency response. It is recommended that you experiment, and use the one you think sounds better to you.

        There is no other way to extend the cable without the power-module and subsequent XLR cable. To avoid using batteries, it is recommended that you enable Phantom Power. If you do not have a Phantom Power supply, we manufacture the AT8801.

        If you have further questions, please contact the Audio-Solutions Department (audio-solutions@atus.com).

    • Q:

      for U853A what is the effective distance from microphone to signer

      We bought 6ea of U853A for stage performance, both choir and skid. But we felt we can't make it works the way we expect. So please help. (1) The first question is what is the recommended distance range from microphone to signers (2) what is the difference between -- and -/ choice. (There is one switch on the side of power module, 3 position, off, -- and --/,) I think the --/ is for hanging and ---- is for mount on the microphone pole ? Is that right ? If ---- is for regular usage, please advise how to use it, just like regular microphone ? Thank you very much
      If the included 25' cables is not enough, what kind of extension can we use ? Any P/N ?
      Asked on 9/23/2012 by bwav from Los Angeles, CA, USA

      1 answer

      • 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".

        http://www.audio-technica.com/cms/site/8b7788c462fa04c4/index.html

        To answer your questions one-by-one:
        1) Refer to the above information.
        2) Bent line = low end roll-off. it reduces some low end information. Use if you think it sounds better.
        3) Refer to #2.

        If you need an extension, a standard copper-braided XLR will do. If you have addition questions after thoroughly reviewing the above, please contact audio-solutions@atus.com.

    • Q:

      What would be the max hanging height?

      I am looking for a microphone for my assisted listening system and do not want a mic that hangs too low into the sight lines. I would need it to hang about 18 feet of of the floor.
      Asked on 8/16/2012 by fatchanceofanickname from Middlebury VT

      • A:

        Thank you for your inquiry. 18 feet would be too far to make any microphone effective in your scenario. If your source is spoken word, no more than a few feet is necessary. Otherwise you will pick too much backround noise.

    • Q:

      Missing windscreen

      I purchased three Pro 45's and two of them are missing the wind screen. I wanted to know if your company could provide those since they were missing during purchase. Or do you think that the wind screen isn't necessary in the church environment with commercial construction. Please do tell me what to do
