The Deluxe Audio Technica Cardioid microphone system utilizes matched set of Audio Technica AT831 Cardioid microphones. These microphone come with permanently installed high quality, double shielded microphone cables. The standard configuration comes with the two 48” microphone cables (other lengths also available) terminated together into standard stereo gold plated 1/8″ (3.5mm) mini plug. The high SPL versions (with XLR phantom plugs or with the AT8532 power modules) come with each mic on separate cable and connector. Custom cable lengths and configurations are available call for details.
General information about our Cardioid microphones is available here.
There are several ways to power these microphones. Each of these options provides the same sound quality, the only difference is the maximum sound pressure level (SPL) the mics can handle.
The microphones can be powered with normal plug-in-power, available on many portable recorders and camcorders. With this type of power, the mics will handle reasonable sound levels. If you will be using the mics in high SPL (sound pressure level) situations, the microphones require additional power, beyond the normal “plug in power”. You will need to use one of the powering schemes described below:
1 – For strong sound levels, consistent with moderately loud amplified concerts, you can add battery module for increased high SPL performance and dynamic range.
2 – For strong sound levels, consistent with loud amplified concerts when your recorder/mixer, etc. supplies phantom power, you can add the high SPL modified XLR connectors. Each mic has it’s own XLR connector and cable and microphones ordered this way will not work with plug in power or standard battery module as shown above. You can see this microphone with this configuration here.
