A microphone’s polar pattern is the 3-dimensional space surrounding the capsule where it is most sensitive to sound. There are quite a few different patterns but here are 3 of the most popular.
If you have ever stepped up to a sound board you’ve probably seen a few knobs labeled HPF and LPF. What do those mean?
HPF and LPF stand for High Pass Filter and Low Pass Filter. Some boards have just a HPF, while some boards, especially digital, give you both. A HPF allows high frequencies to pass through, meaning it will filter out low frequencies. Some consoles have a HPF button that has a set cut at 120 or 150hz. A HPF can really help clean up vocals or instrumentation that doesn’t have a lower frequency.
A LPF does the exact opposite. It allows lows frequencies to pass through and filters out high frequencies. This is a great tool for instruments like a bass guitar or a kick drum to clean give a clean low end to your mix!
It's a simple tool anyone can use! Try it out and see the difference it can make in some of your mixes!
The HEIL PR 22 microphone is a dynamic cardioid microphone that offers greater articulation throughout its entire frequency range and has low handling noise. Noise directed at the rear of the mic is virtually eliminated through a combination of special porting & phasing plug design. This mic is a sound professional’s dream, come true.
Best-in-class rear noise rejection means that you’ll get more sound out of the PR 22 before feedback occurs. The PR 22 microphone has exceptional mids and highs. This mic is a stage-friendly mic that can take a full-on snare hit & deliver the richest sounding snare with no overload
The PR 22 is able to deliver rich vocals, warm & accurate guitar, crisp snare drums with depth, clear piano and more to the board like never before. Whether you’re recording with the PR 22 in the studio, or using it for live production, your ears will tell you it was a good choice. We love using this wireless mic with clients. It’s easy to use and produces the quality sound you need.
Equipping You To Be the Best!
Have you ever wondered how some of those special features work on your AV equipment? Here at Lambda AV we are dedicated to making your AV experience the best it can be! In our efforts to do this, did you know that Lambda offers classes and training sessions at your convenience? Yes! We do! We would love to help you and your volunteers better understand any AV equipment you have. From lighting and video to sound systems we've got you covered!
Training sessions are created for your specific needs. Lambda offers training for a few hours on any system. We also offer half day training and full day training with a free lunch provided! If a full day of training and a tasty meal isn't enough we also offer training with a checkup beforehand. This includes updating your system and fixing any connection issues you might have. Sound specific training can include your band or we can come set up multi-track recording, if your system is compatible, and practice using those tracks. The opportunities and options are limitless! There is no point in having new gear if you don't know how to use it to it's best ability. Let us show you all the tips and tricks we know!
If you are interested in knowing more about our classes and training, give us a call for a free consult.
How many times have you snapped the top off a cat5 ethernet connector? Or how often have you crushed it in a high traffic area? Wouldn’t it be great if it looked like a protected xlr end?
Popular in the live production world, but lesser known in other av fields, an answer to this problem is already around. Welcome to the Neutrik “Ethercon” connector. We use these connectors anytime we want to make sure an ethernet cable stays plugged in. If it's used often and we want to make sure the end does not wear out. we use them too. You can add female ethercon connectors to stage boxes or wall plates, and even many times add the outside of an ethercon connector to an existing cable. Check out this link to the Neutrik page and let us know if we can help ruggedize your stage connections!
MI-909 is an industry first, professional quality digital wireless stereo IEM system. Featuring digitally encrypted technology with unparalleled digital audio performance and transmission reliability, the superior frequency response characteristics of the MI-909 from 20 Hz to 15 kHz clearly exceed those of analog systems. Combining DSP & digital diversity technologies, this upgraded MI-909 system has advanced features and is a professional quality IEM system won’t break the bank. It can host up to 16 compatible channels within the same frequency group. It also has free scan. It selects an open, interference-free transmitter frequency and ACT syncs the transmitter and receiver frequencies automatically. The key components of the MI-909 IEM system include the MI-909R ultra compact bodypack receiver and MI-909T rack transmitter.
We have used this system on several installations including in Florida and Denver. We’ve used it recently in two different ways. We have used this on stage in conjunction with an on-stage personal mixing system and we have also rack mounted these boxes and fed them directly through an aux. Paired with the MIPro antenna distribution system this can offer a more cost effective solution to getting wireless in-ears onto your stage. If you’re wondering if this would be right for you, we are here to answer any questions you might have!
What Are They? And Why Are They Useful?
A few times recently we have run into venues and sound technicians that donʼt know about how useful these little Direct Boxes are so we thought this would be a great tech tip to cover. We hope you learn something new and would love to answer any other questions you might have.
A direct box is a device used to interface a guitar or keyboard to a sound system. Inside the box is a set of transformers or coils of wire. The windings of these coils change a signal from high impedance to low impedance. Instruments usually have a high impedance signal because it is a stronger and higher quality signal, however, this signal type has some negatives. It is prone to interference over even short distances and it usually does not interface well to a sound board with low impedance “pre-amped” inputs. Plugged straight into a sound board with an adapter cable instead of a direct box, a guitar will be too loud, and have hum or interference. A direct box allows for a short un-balanced high impedance cable to be correctly converted to a low impedance signal. It then sends the signal down a balanced cable to the sound console.
We always recommend having a few of these around as part of your “problem solver kit”. If you want to know how to integrate these little boxes into your system, contact us anytime!
In the audio/visual world one of our biggest fears is that something might go wrong or not work at the worst possible time. One of the ways we have found to minimize the chances of this happening is through a pre-event checklist. Whether producing or directing an event, mixing audio, or even just operating a camera, having a checklist to confirm everything is working properly can save headaches during the event.
If you are using volunteers, who may not work with that piece of equipment regularly, this can also help you empower them to learn that area or piece of equipment. Keep the checklists simple and make sure if the operator doesn’t use that specific equipment regularly that they can still understand it and use it as a guide to help them. Use your checklists as markers of what should be working and what someone should be seeing regularly.
Spending a few minutes to create a checklist for different pieces of your systems can save you lots of time before and during your events!
