Mix it up with Yamaha’s TF1 mixer! Yamaha has created a new mixing console to truly give you more freedom and creativity with your mixes. The TF1 is a rack mountable, digital audio mixing console expandable up to 40 input channels. TouchFlow Operation™ introduced in the TF series consoles allows the user to respond to the music and artists on stage with unprecedented speed, taking live sound reinforcement to a new level of refinement. With the TouchFlow optimized for touch panel control, experienced sound techs as well as newcomers to the field will find it easier than ever to achieve the ideal mix. This console also has advanced live recording features and seamless operation with high performance. The TF series has also added the latest touch-screen technology to deliver an evolved experience in console operation. Smooth setup and operation, practical presets and refined design, along with software applications that integrate seamlessly with the entire system make the Yamaha worth talking about. They offer comfort and convenience in their consoles, for a wide range of users and applications. If you want to know more, don’t hesitate to ask!

A few weeks back we talked about the “Lambda process” for turning your dreams of a new audio, video or lighting system into a reality. Part of that process is all about the gear testing that happens before the equipment ever gets to your location. After the gear has been ordered and has arrived in our shop, we set up all the equipment and each component in the shop just as it will be for the install. This ensures that when we arrive for the install, there aren’t any surprises and there won’t be “that one missing part.” Plus, we have an assurance that each piece of the gear we install will work for you leaving no questions of whether your new parts are faulty.
A few articles ago we talked about HDMI cables and the drawback of only being able to run them 25ft or so. We also talked about how you can use SDI to get HD video signal over a long distance. But that isn’t all we have to tell you! There is a third option for you to consider! This signal is a new comer on the video scene and is called HDBaseT. This signal was first created in 2010 and can be used for the transmission of ultra-high-definition video, audio, Ethernet, control, USB and even up to 100W of power! All of this is over a single cable! It’s the Mary Poppins of cables! HDBaseT uses Cat6a cable, but because of all the different functions it can be used for, it uses specialized connectors. These look identical to a standard RJ45 connector but be warned! Because HDBaseT carries power as well, if you plug it into a standard RJ45 jack you can severely damage that piece of equipment! If you are unsure, its always better to ask rather than risk your equipment.
HDBaseT can be run up to 328ft giving far more flexibility in running video signal. This cable is also extreamly convenient in instances when paired with a piece of HDBaseT equipped gear. The PTZ camera, for instance, would usually require up to 3-4 cables for signal, power, and control, but with an HDBaseT connection you only need one! Think about all the money that could be saved by only running one wire connection. Not to mention the amount of time running cable through walls and ceilings. If you have a hard to reach place or a tangle of cables attached to that old equipment, it could be worth your time and money looking for an HDBaseT piece of equipment as a replacement and running one cable instead. AAFCU Case StudyMeeting rooms in recent years have made a major transition in space needs. Gone are the days of a central computer at a podium or lectern in the corner or a large rack of automation equipment. The purpose is no longer for a single executive to speak to a room of employees. Meeting rooms today are dynamic environments with a number of people presenting in a live and cooperative environment.
This is where we began with AAFCU a local credit union in Colorado Springs, Colorado. Their IT staff came to us with the challenge of cleaning up an aging mess of wires and updating technology to turn an often-used board room space into an environment for creativity and corporate inspiration. The first goals set were to clean up the existing hardware that had been ad hoc over the years for conferencing. Next they wanted to update viewability around the conference table for better engagement of all employees. The staff at Lambda Audio Visual set out to understand the problems of the conference room and it's designated uses and put together a solution to make the room usable for a new generation of meetings.
Here’s something new for you to check out! The Superlux IS-103 is a complete wired intercom system that provides clean, clear communication for video, film, broadcasts, house of worship and schools! This Superlux is a great low cost solution for auditorium and church staff communication between positions. It uses simple XLR mic cable and can support up to ten belt packs so you can keep everyone in the loop! Comfortable, lightweight and easy to use, this could make communication seamless for everyone involved in your project. We love finding and providing affordable options for our clients for all your needs. If you are looking for something in particular, don’t hesitate to ask!
This week we are excited to take a look into the second part of our cable series!
Now like XLR mic cables, instrument cables also have a doppelganger. That is, the speaker cable. These two look the same, but are used for different purposes. An instrument cable is low power and high impedance. On the other hand, a speaker cable is the opposite, high power and low impedance. Speaker cable is built to carry a strong signal from your amp to your speakers, a signal with a relatively high AC current and voltage. Because of this difference, speaker cables require a higher gauge wire.
So, always make sure you’re using the correct cable for its intended purpose. Good news is it's an easy fix if you know what to look for! 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! |
