  • What are Half Cardioid Boundary Microphones?
    Half cardioid boundary microphones, also known as half-cardioid boundary mics, are specialized audio recording devices that are designed to capture sound from a specific direction while minimizing unwanted background noise and reverberation. They utilize a half-cardioid polar pattern, which is a variant of the traditional cardioid pattern, to achieve this remarkable level of precision and focus.
  • How do Half Cardioid Boundary Microphones Work?
    Unlike traditional microphones that pick up sound from all directions, half cardioid boundary microphones are strategically positioned on a flat surface, such as a table or a podium, to take advantage of the boundary effect. This effect occurs when sound waves encounter a surface, causing a boost in sensitivity and directing the sound towards the desired source. By harnessing this phenomenon and combining it with the directional properties of the half-cardioid polar pattern, these microphones excel at capturing sound from a specific direction while minimizing off-axis noise.
  • Are there any specific maintenance requirements for half cardioid boundary microphones?
    Half cardioid boundary microphones are generally low-maintenance devices. Regular cleaning with a soft, dry cloth and storing them in a protective case when not in use will help ensure their longevity and optimal performance.
  • Conclusion

From conference rooms and lecture halls to courtrooms and performance venues, these microphones deliver exceptional clarity and intelligibility, ensuring that every word is captured with accuracy. So, whether you're leading a meeting, delivering a presentation, or participating in a lively discussion, harness the power of sound with half cardioid boundary microphones.
  • Can I use multiple half cardioid boundary microphones together?
    Absolutely! In fact, using multiple half cardioid boundary microphones in large conference rooms or performance venues can significantly enhance audio coverage and ensure that every participant or performer is captured with optimal clarity.
  • Do half cardioid boundary microphones require phantom power?
    Some models of half cardioid boundary microphones do require phantom power, which can be provided by an audio interface or mixer. However, there are also models available that can be powered by batteries or USB.
  • Advantages of Half Cardioid Boundary Microphones
    Half cardioid boundary microphones offer a range of advantages that make them a preferred choice in various applications. Let's explore some of the key benefits: 1. Superior Directionality Thanks to their half-cardioid polar pattern, these microphones exhibit excellent directionality, allowing them to capture sound primarily from one direction. This is particularly beneficial in scenarios where there are multiple sound sources or when you want to focus on a specific speaker or instrument in a crowded environment. 2. Enhanced Off-Axis Rejection In addition to their superior directionality, half cardioid boundary microphones excel at rejecting off-axis noise. By minimizing sound pickup from the sides and rear, they ensure that the desired sound source is captured clearly and without interference from ambient noise. 3. Reduced Reverberation Reverberation can often be a challenge in environments with reflective surfaces, such as conference rooms or lecture halls. However, half cardioid boundary microphones mitigate this issue by taking advantage of the boundary effect. Placing the microphone on a surface allows it to capture the sound directly from the source while minimizing reflections and reverberations. 4. Versatile Applications Half cardioid boundary microphones find applications in a wide range of professional settings. They are commonly used in conference rooms, boardrooms, lecture halls, courtrooms, and live performance venues. These microphones excel at capturing speech, presentations, discussions, and performances with exceptional clarity and intelligibility.
  • Half Cardioid Boundary Microphones in Action
    To further illustrate the versatility and effectiveness of half cardioid boundary microphones, let's explore a few practical scenarios where these audio devices shine. 1. Conference Room Meetings In a bustling conference room filled with participants, clear and intelligible audio is crucial for effective communication. Half cardioid boundary microphones placed strategically on the meeting table ensure that every voice is captured with precision while reducing background noise and echo. This enables seamless discussions and productive collaboration. 2. Lecture Hall Presentations In lecture halls and educational settings, it is essential for the speaker's voice to be projected clearly to ensure maximum engagement and comprehension. Half cardioid boundary microphones placed on the lectern or podium provide exceptional speech intelligibility by capturing the speaker's voice while minimizing distracting background noise and reverberations. 3. Courtroom Proceedings In legal proceedings, accuracy and clarity in capturing spoken words are of paramount importance. Half cardioid boundary microphones placed on the judge's bench, witness stand, and counsel tables ensure that every word spoken in the courtroom is captured accurately, facilitating a fair and transparent legal process. 4. Music Recording and Live Sound Applications While many boundary type microphones do not lend themselves well to full bandwidth sound recording and live performance, the studio quality electronics and features of the Teegarden Audio PAC-116, like -12dB Pad and Full Range response for music or the low frequency filter for speech and stage offer excellent results on various instruments like piano, acoustic guitars, percussion, drums in all settings.
  • Can half cardioid boundary microphones be used in outdoor environments?
    While half cardioid boundary microphones are primarily designed for indoor use, there are certain weather-resistant models available that can be used in controlled outdoor environments with adequate protection. The PAC-116 is robust enough to hangle outdoor sound applications as long as they are not left out, exposed for long periods of days.

  • How can I REAMP with the Mono Magic Active DI?
    Simple but not necessarily straightforward: 1. You can REAMP with eh Magic Active DI by connecting an Instrument or Line Level source using the Combo 1/4"/XLR input connector on the front. 2. You must engage the -20dB Pad switch 3. Your output to an amplifier or EFX loop MUST come from the Active Buffered Thru output. 4. The box must still be simultaneously Phantom powered with 48V from a microphone preamp, console channel or external 48V Phantom Power Supply. The balanced output signal will be available here as well but be careful not to create audio feedback loops or you might destroy your monitor speakers!
  • What is the best way to hook up and operate my Fatboy Tube DI?
    To hook up your Fatboy Tube DI follow these ordered steps: 1. Connect the power connector to the back of the unit 2. Plug the power supply or power cord of the HD Power Supply to a AC Wall Outlet 3. Connect an XLR cable from the Line Output of the Fatboy directly to your converters (recording) or to a mixing console (live).* 4. If possible, let the unit (tube) warm up for 20 minutes to an hour before playing 5. Connect a 1/4" cable to your instrument first then to the "Push" input on the front of the Fatboy. 6. *Set the "Beef" (Attenuation) knob to around the 75% or 3 O'clock range. When connected directly to digital converters an XLR to 1/4" TRS (balanced) cable adaptor may be needed. Instruments with passive pickups can probably be used with the Beef gain set all the way up or fully clockwise. Back the level off as needed for instruments with active electronics. This should give you a fairly precise and optimum recording level to your recording system. Bear in mind, the Fatboy is actually a 26dB preamp and needs no further mic or line preamps for optimal operation and sound. 7. For live sound applications, we recommend starting with the Line Output and working with your FOH sound engineer to get an appropriate level with the Beef (gain) setting as previously recommended. They may need to turn their gain settings all the way down our use a -20dB pad if there are no Line Level Inputs available on the sound console. Adhering to this recommendation will give you the optimum signal to noise and tone performance from the Fatboy Tube DI. If all else fails to give the desired result, the Mic Level output is available and will send a traditional DI level to the house mixer.
