  • Q & A

    Which system is this microphone compatible with?

    Alanna G.

    Thank you for your inquiry. This model ending in lower case "a" is a wired XLR version to be used with any XLR mic input on an interface or mixing console. If you are looking for an ATM73 to use with an Audio-Technica Wireless System with the 4 pin connector, the model number would be the ATM73cW: http://www.audio-technica.com/cms/accessories/8d419590fb003ecc/index.html

    Which model of the ATM73 will work with my ATW-T210a beltpack?

    James the Drammie

    Thank you for your inquiry. You will need the ATM73cW.

    model number of the replacement ear pads

    Ow! you're on my hair

    Is the connector on the ATM73a compatible with my system 10 belt pack?

    Rich

    No, it is not. You want the ATM73cW which has the appropriate connector.

    How do I wire a 4 wire unterminated cable for an ATM 73 to suit a 3 pin AKG belt pack.

    Is the Low Frequency Roll-Off always activated, or can it be turned on and off? I need a microphone to record speech samples for acoustic analysis. This microphone is attractive because the frequency response extends down to 40 Hz. However, I see that this product has Low Frequency Roll-Off, which might affect the ability to pick up some speech sounds in the lower frequency range. So I was wondering if the Low Frequency Roll-Off is always activated, or if it can be turned on and off?

    Please read the below information: The ATM73a comes with the AT8531 power module. The power module that comes with some condenser microphones provides several important functions. First, it converts the 11 - 52 VDC phantom power into a smaller DC bias voltage used to power the FET impedance matching circuit inside the microphone. Also, it provides a SELECTABLE low frequency roll off, supplies battery power if phantom power is not available, converts the signal to the proper impedance and balances the output. The power module is a necessary component. Thanks!

    Is this mic any better than the atm75 for vocal singing performance

    Montey

    The ATM73 is not necessarily a "better" microphone; it just sounds different. However, the ATM73 does have better specifications. Every microphone sounds different and is dependent upon what sound you're going for. Personally, I prefer the ATM73 because it has a little more low-end (bass) response and can handle more Sound-Pressure-Level (SPL), as compared to the ATM75. Thanks!

    What do the terms "Terminated" and "Unterminated" mean?

    Yankee

    Thank you for your inquiry. Terminated means that it has a connector at the end of the cable wired for a specific system. Unterminated means there is no connector and the end of the cable is just bare wire. This is for those who want to wire it themselves for a specific system.

    is this mic suitable for Group Fitness? I notice this mic is suggested for drummers who I assume get sweaty. So, is this mic suitable for group fitness where we get very sweaty, is it sealed to be sweat resistant?

    Julieanne

    Thank you for you inquiry. Yes, it can be used for a fitness group, although i recommend the Pro 8he instead. It is a very similar mic and costs much less.

    ATM73a Cardioid Condenser Headworn Microphone I want to replace the pads that go between the headset and my head. Can these be purchased? Also, is there perhaps a foam cover that goes over the existing pad. Thanks, Thom
