LiveMix - Personal Monitor System

AddThis Social Bookmark Button

Let's just call this a pre-review because we're pretty early in the acceptance cycle for LiveMix, but all looks pretty convincing that this is a personal monitoring solution that is both affordable and effective.  As they say "Simple enough for volunteers, deep enough for professionals." 

The system is available in two packages - one with analog inputs and one with Dante for digital.  Both are $3999 for eight users with mixers, cables, a hub, mic stand mounts, and your choice of input device.  Additional personal mixers (each accommodates two users) are just $524.99. 

We were introduced to LiveMix by one of our larger church clients and also by a system integrator in the upper midwest.  Take a look at the video below (it's well thought out and tells the story pretty convincingly), and if you'd like more info, give us a call at 800-747-7301.  We'll have it up on the site for purchase soon. 

 

 

Bose L1 Compact - perfect portable PA system

Could there be a more polarizing company in the universe of audio than Bose?  Bose's marketing slogan is "Better Sound Through Research".  Critics have restated that as "Better Sound Through Marketing" and have derided the product with chants of "No Highs, No Lows, must be Bose."  Frankly, I like Bose products, in general, and have wondered what I've been missing that others have found so easy to dislike.  Sure, they've had some dud products, but so has every other manufacturer on the planet. 

Let me introduce you to the Bose L1 Compact by telling you my story.  Several months ago, our Bose sales rep dropped off the L1 Compact and left it.  He said "Just try it someplace, and I think that you'll like it."  A week went by, and then another, and then two more.  I hadn't touched it, and I knew that he'd want it back.   Plus, I had given my word that I'd try it. 

At the church I attend, we were planning an outdoor service to dedicate our community garden and I had been asked to make sure that we had a sound system capable of accommodating both acoustically-flavored live music and the spoken word for about 150 people outdoors.  And any of you who don't have a dedicated portable sound system at your church (and who know what a pain it is to round up a system in order to take something outside) will appreciate what I'm about to write. 

I had spent the better part of two hours going down to church, looking through the youth system, the main system extra gear, even the old gear, and thinking about how to get the system outside while still being ready inside for the regular service.  That day, I would be the lone sound technician for both locations and there wasn't another experienced tech to be found, even to carry a speaker.  Thinking about what might have been unassisted set-up and tear-down, I was a little bit stressed and maybe a tad bit grumpy.  Maybe.  Most of you have probably never felt that way. 

Then it dawned on me.

Eliminating Wireless Dropouts

Multi-path interference is the most common cause of wireless drop-outs, and if you can get rid of multi-path, you can get rid of a good number of headaches. So what exactly is multi-path interference? 

This post explains multi-path, diversity receivers, and a new antenna for eliminating the problem.

When a microphone transmitter sends out a radio wave signal, it spreads through a room, like ripples on a pond. As the wave encounters flat surfaces, like walls and ceilings, it reflects and continues forward at different angles. Since there are multiple surfaces in every room, there are multiple reflections and hence multiple paths--some longer and some shorter--that a wave takes before reaching the wireless receiver.

Usually, the receiver is able to process two or more signals arriving at slightly different times without difficulty. But if the signals overlap in such a way that they cancel each other out (creating a “null”) you get a drop in volume or complete drop-out. Sometimes, the shape of the room can cause a multi-path null to perpetually hover over a receiver. Other times, when the speaker walks past a certain spot on the platform, a dead spot will develop and you’ll hear a quick drop-out.

Diversity receivers filter out multi-path interference by using two antennas instead of one. Most wireless receivers that have two antennas are diversity receivers. Since a multi-path null occurs only in specific and relatively small locations, it is less likely that a null will exist over both antennas. This is called “spatial diversity.”  But spatial diversity does not work 100% of the time.

Our favorite intermediate class LCD projector - Panasonic PT-VW440U

We like it.  It's bright - 4800 lumens, great color accuracy, wide-format projection, it has an HDMI input, and it's reasonably-priced. 

It's easy for people who sell products for a living to get excited about something they sell, but just 5 years ago, we were excited about another projector that was just as much of a relative bargain by comparison to what was out there at the time. 

At the end of 2007, my own church needed new projectors and Sanyo had just introduced the PLC-XU48.  3000 ANSI lumens, and an analog VGA interface.  3000 lumens for $1699?!  At half of what we would have paid the year before for something similar, we said "we'll take two!"  They're still doing a nice job for us on 6x8' screens.  At the time, the PLC-XU48 was one of the brighter ultraportable projectors, a class of machines that were more typically used in a boardroom than a worship space, but that's what we could afford.  And as it turned out, they were exactly what we needed. 

As we approach the end of 2013, I'm hoping to get another year or two out of those old Sanyos (and expect that we will).  But if I were choosing a new projector today, the Panasonic PT-VW440U would get my vote

You can read specs until you're fully informed (or confused), but let me tell you why I'd pick it.  First...

Innovation or Copycat? Voice Technologies VT901 Earset

AddThis Social Bookmark Button

It's been more than five years since Countryman changed the face of audio with its E6, an ultraminiature earset microphone.  With tens of thousands sold, you could argue that the lavaliere microphone is nearly obsolete for live audio and that the E6 has been a gamechanger for speech applications.  With its success, the E6 spawned a host of copycat products; some good, some not so good and some better, but no one can argue that the E6 set the standard. 

A couple weeks ago, I called one of our suppliers to order a product for a client and a familiar voice answered the phone.  It was my friend Bryce Boynton.  For several years, Bryce worked for another microphone manufacturer, and he had just started the new job.

We talked for a few minutes about how a guy from Colorado was settling in in the northeast, and as we talked, he said, "Hey Dave, I have a microphone that I'd like you to try. It's an earset, and I think that you'll like it."  Bryce came from one of the world's premier microphone manufacturers to this position, so he's a microphone expert, and I thought to myself...
