    • Q:

      Hi, we bought AT803 assuming it is ready to be connected to ZOOM H6 handy recorder.

      After opening the box I see output connector XLRM type female. From what I understand we need an adaptor XLRM male to XLR male. I cannot find such product. Please advice.

        A:

        The AT803 will connect into the body pack. From there, you will run a standard XLR cable (Male-Female) from the body pack into your camera. Make sure your camera has an XLR input as it requires this type of connection.

        Additionally, this microphone is a condenser and will require Phantom Power in order to operate. Phantom power can be supplied by a battery (by opening the latch on top of the body pack) or by your camera.

    • Q:

      I'm considering using the AT803 with an Iphone6. Can I purchase and adapter for the 3-pin mini connector to 3.5 MM jack and use the lavalier mic directly this way without the power module or do I have to use the AT8531 Power module and purchase a XLR Female to 3.5 MM jack adapter? I currently use a Zoom recorder with this but need something quick and portable.
      Many thanks.

      I have an AT803, but need a cardioid mic as well. Is there a cardioid mic (sold separately) that will interface with the power pack for the AT803? Or do I have buy an entirely separate system?

    • Q:

      Can the AT803 be powered by Zoom H4n?

      I understand that it should, yet I do not get any signal when the AT803's external power box is turned off. I have ensured that H4n's phantom power is turned on (I've tried both 24v and 48v), and that it is plugged into to a power supply. Recording levels are also turned way up.

      I'm connecting into the Zoom's XLR input. Everything works fine when the mic's external battery pack is switched on. But I'd rather not rely on that (or even carry it around) if I don't have to.

      Can you please help? I love the sound and build of these mics but I may have to return them if this can't be corrected.

      • A:

        You have to use the provided (AT8531) inline Power Module. Like all condenser type element microphones, some amount of power is required to operate the microphone. You may power the microphone by applying phantom power to the module, or by placing the single AA battery into the power module. A power module performs three crucial functions for a condenser type element microphone. When phantom power is applied to it, the module manages phantom power by stepping it down to a much lower bias voltage for the microphone. This bias voltage typically ranges anywhere from 1.1 to 5 volts. The module also balances the signal at its' 3-pin male XLR output connector and determines the output impedance.
        The switch on the side of the power module can be used to turn the microphone off if needed (whether the mic is being phantom or battery powered). Otherwise it is typically left in either the ON / straight line position (no low roll-off filter engaged) or in the ON / bent line position (low roll-off filter engaged).
        If you are battery powering your H4n, I recommend installing the battery in the power module to power the microphone. By not using the phantom power on the H4n to power the module, you would be reducing the demand on the battery in the H4n. If you are AC powering the H4n, you can use phantom power if you wish. In demanding (such as high SPL) circumstances it can provide better microphone performance. Leaving the battery installed can provide continued microphone operation in the event phantom power is interrupted for some reason. If phantom power is lost, the battery will take over and power the microphone.

    • Q:

      Is the AT803 compatible with a Sony a77 dslr?

      I have just received my AT803 and used my xlr cable to adapt it. however it will not work and i tried using a new battery, plugging and unplugging but nothing will work.

      please help me i have an interview set up for tomorrow!!

      • A:

        Make certain the switch on the side of the (AT8531) power module is turned ON. This is a 3-position switch. OFF (no sound is produced), ON / STRAIGHT LINE (sound is produced and the low roll-off filter is bypassed) and ON / BENT LINE (sound is produced but the low roll-off filter is engaged and frequencies below 80 Hz are rolled-off at a rate of 18 dB per octave). The Sony AT77 appears to have a stereo MIC IN jack. If you are still not able to get the microphone working, please contact our Audio-Solutions team at (330) 686-2600 extension 5000 or audio-solutions@atus.com and provide the make and model of the cable that you are using to connect the XLR output of microphones power module to the MIC INPUT jack on the camera.

      Can I use the AT803 with transmitter ATW-T210? And if so, do I have to use power module AT8531 with it?
      Asked on 2/19/2014 by kellyecl from United States

      1 answer

      • A:

        The AT803 is a wired microphone, and cannot be directly connected to the ATW-T210.

        However, the only work-around would be to purchase the Audio-Technica XLRW, which will allow you to connect the microphone's including Power Module (AT8531) to a T210 bodypack transmitter. You would need to use a battery in the power module to power the microphone, since the XLRW does not pass any voltage.

        Thanks!

      How does phantom power work? What is the voltage source?

      I do not understand how the mic gets phantom power. This should be explained better.
      Asked on 9/14/2013 by gamba

      • A:

        Thank you for your inquiry. Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule - sometimes through a power module. The power module attached to the mic unit converts the 9 - 52VDC into a small bias voltage that the mic capsule's FET needs for the microphone to operate.

        A balanced mic cable has three conductors; Pin 1 is ground, Pin 2 is audio positive, and Pin 3 is audio negative. Most microphones produce a positive voltage on Pin 2 when sound pressure is applied to the diaphragm.

        Phantom power is 9 - 52VDC applied across Pin 1 and Pin 2 - and at the same time applied across Pin 1 and Pin 3. The term 'phantom power' was assigned because if you take a measurement across the two audio lines - Pin 2 and Pin 3 - you find 0 Volts DC. The voltage does not affect the mic signal.

        Thank you for your inquiry. The ATW-2120a is a hand held wireless system. You would have to purchase a system with a belt pack transmitter such as the ATW-2110a, along with a microphone such as the MT830cW or the AT831cW.
