Microphone Techniques

Presented by
Ken Simons & Excellence Marketing

Ken will share his knowledge & working experience about the different types of microphonesavailable along with helpful hints on how to select the right one for your application (and budget!).   We will use live instruments to apply different techniques and microphones from various manufacturers. Participants are encouraged to discuss their own specific application needs to make this a truly interactive & useful evening.This year we will focus on the demonstration of different mics and techniques. Using multiple microphones and listening to the differences between them and discussing why we would choose a mic for it’s specific characteristics based on the style of music you will be using them for.  We will specifically focus on KICK, SNARE, TOMS, PIANO and ELECTRIC GUITAR.

Little Morsels You Should Know…….METERS

Behold the Mighty Meter! – I see it but what does it mean?

I was thinking about this earlier today as I passed by some old 2″ tape machines.  Not many people understand metering these days.  You don’t see a VU meter that often anymore except when I’m mixing for a broadcast.  

What is a VU Meter?  Well it indicates the Volume Unit.  Often also referred to as a VI (Volume Indicator).  Other metering characteristics we run into are Peak Program Meter or PPM.  With today’s mixers we tend to see the PPM more often.  Although in today’s audio world it’s getting increasingly more difficult to find a meter that adheres exactly to a standard.  I used to use the VU or VI meter most of the time but now only when I’m at a broadcast station.  I still love them and they track the loudness component of a signal which is related to RMS. (Root-Mean-Square)  The zero reference on a VU is typically +4 dBu and the range is -20dB to +3 dB.  The meter is blind to peaks and is slow in response time.  Some used to also have peak LED included which I found especially useful.  

The PPM or Peak Program Meter tracks peaks of the audio, kind of….  The true peaks can exceed the indicated peak by up to 8 dB.  The meters tend to ignore quick short term peaks for which clipping would not be audible.  PPM’s are great for getting the full, usable audio level out of your device.  OK.  That’s geeky enough for now.  Perhaps I’ll delve deeper another

Continued Education in little morsels.  Lesson #3
The Inverse Square Law

In physics, an inverse-square law is any physical law stating that a specified physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. 
Blech!  Now take a breath after reading that….how does it relate to us audio heads?
Like dB relationships, this is an important fundamental concept of acoustics that has powerful ramifications to us.  In basic terms, the law states: for every doubling of distance from the source (in a perfect world, in free space, i.e., no reflections) the acoustic power is reduced by 6 dB (4x).  Mainly, this is important to understand within the contest of coverage, the amount and type of loudspeakers needed, and the resulting amount of amplifier power required, etc.  We use this everytime we mix.  The distance the singer is from the mic or the speaker is from the audience.  Understanding the Inverse Square Law is vital to any audio engineer.  Questions on how this relates to you?  Give us a call!  I can geek speak all day long…..

The White range is a dedicated install series consisting of 16 new speakers. These range from the smallest of the White range, the 4S which is a 4″ coax box weighing a mere 2 lbs and capable of max SPL of 115 dB.

Up to the 10AL/10AL-D which is a 2-way 10″/ 2 x 1″  line array box equipped with integrated rigging for very clean install The 10AL/AL-D is  available on a 75 and 105 degree versions, weighing in at 31lbs and max SPL of132dB.

The White range is available in 124 standard colors plus custom colors, weather resistant versions and are compatible with all D6 & D12 amplifiers. Look for more information to come as well as product demos. The official US lauch will be at InfoComm June 15th -17th in Orlando.

I have to say they sounded amazing, just what you would expect from d&b!
