It's time to check out a few different cables and exactly how they can effect your AV systems performance. There are so many different cables and making sure you know the difference and know which fiber to use could make the change you've been looking for.
Let's start with Mic cables! These are one of the two cables that you will come across on a regular basis if you work with audio. Now, mic lines actually consist of two components. The mic cable and the connector. The connector is an XLR connector. The reason this is an important distinction to note is because the XLR connector can be used for different connections, specifically 3-pin DMX. This can become confusing as on many stages you will see both mic lines and DMX cable. Now while these two cables look the same they are doing two completely different jobs. While mic line passes audio signal, DMX passes data and requires a much higher specification cable to perform that task. Because of that you can use a DMX as a mic line, but you should not use an mic cable as a DMX line. If you are in a situation where both mic and DMX 3pin cables are being used close to each other, it’s a good idea to mark or label each cable to ensure you or your volunteers don’t mix them up!
The reason XLR connectors are used on the end of mic lines to pass audio signal is that they allow you to pass shielded, balanced audio. I’m sure if you’ve spent any time in the audio world you hear the terms balanced and unbalanced audio. So, what is balanced audio? Mic line consists of a positive, negative and ground cables. The ground pin allows the signal to be shielded, cutting down on the amount of noise that can be introduced. The positive pin carries the signal and the negative pin carries the same signal with the polarity inversed. When the signal is combined at the other end of the cable anything that is not native to the audio signal will get canceled out. Because of this the final audio signal will have almost no unwanted noise from outside electrical interference. This preserves the original audio signal and gives you the ability to pass audio signal over very long distances.
Pretty neat, right? Cabling may seem insignificant, but it can really effect the quality of your production in the end. Make sure you have the right cables for your equipment and the right connections to create a flawless performance! Stay tuned for more info on other cabling coming up!
I have taken it upon myself this Christmas to bring you a Christmas card! After all, seeing as I’m the one who proudly bares and displays the sheep, I mean lamb-(duh!)-it seemed appropriate for me to be in charge of the Christmas letter! Let me introduce myself: My name is Kirby, the immaculate Trailer. That is, I was, until Ryan recently decided to give me a piercing with a 2x4. It hurt just a little.
We started out the year on the run as we finished a 21 room upgrade with Center for Creative Leadership. Ryan, my proud owner, was more than busy. Training new staff, managing Trevor, bidding jobs, managing Trevor, traveling for installs and conferences, managing Trevor…you get the idea! It’s true, there is no rest for a small business owner. Ryan and Trevor have also have added many more audio, video and lighting trainings to help churches get the most from their equipment. It’s exciting to get new equipment and information into your hands! We love to see you succeed. We also added several more corporate jobs this year. We all loved the work and fun install at Air Academy Federal Credit Union and the video install we did at Air Academy High School
Elizabeth, our Accounting Manager and HR, had a busy year as well. Let’s be real, working with a certain new employee has brought an increased work load to her plate. But she’s a Boss and handled it like a pro! She even planned for the team to make it to Florida for Gather Church’s new building install and back without dying! It was a miracle! Trust me, Trevor almost pulled out the Batman mask one too many times! I had the privilege to carry her well organized snacks and meals for our two week job and even got a security upgrade to help guard the fruit snacks.
Trevor, our Shop Manager and Sound expert, is becoming my new best friend. He takes care of me the best and is in charge of loading up my friends Inigo Montoya, Fezik and Vizzini. Those guys are quite impressive to the clients. They carry all the tools and Lambda tech tip secrets! That is, unless Ryan borrowed something and forgets to put it back… Did you hear? Trevor got SMAART trained this summer! I’m not sure what it did for him, but they say it’s good for the company. We’ve had fun doing audio jobs and SMAART tunes for Lander Church, Clayhouse Church, Austin Bluffs Evangelical Free church and Summit church! Great sound always makes you look more professional. We even created a traveling audio system for Front Range Alliance Church East who rents a gym on Sundays.
Jewell, our Admin Assistant, is enjoying working with the company. Usually I just see her run by on her way to morning meeting, but I hear she keeps things a little better organized in the office now days. Somehow, she even managed to do ordering and communication for our biggest job this year all the way from Italy. Good thing our blog and News Letter didn’t get sent out in Italian. She also has lots of fun working with our vendors and updating the blog and newsletters. I hear the Fun Gear and Tech Tips posted on Social media is an easy way to learn about AV the simple way.
Darcy the Ridiculous Dog chases Hank the squirrel every day. She should just give up. Hank will live on forever! Her other main job is to attend staff meetings and make sure Ryan gets his exercise opening the door for her to go in and out. Yeah, it’s fun to watch
We’ve done a lot of exciting things at Lambda this year! We expanded a lot! Trevor, Jewell, Tych, Anigo, Fezik, Vizzini and myself all joined Lambda this year! And we couldn’t be happier! We have a lot of fun here at Lambda and we hope you've had fun working with us too! We are excited to keep working together and we are excited to work with each one of you in the coming year!
May God bless you richly and may your Christmas filled with much Joy!
From our Family to Yours!
Kirby, and Everyone at Lambda!
PS Could someone stop Darcy from chewing on my tires?
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.
Something you shouldn't live without!
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.
