Hey everyone,
For any of you serious SQ competitors, judges, installers, etc, in either the Houston/Austin/DFW area, or in the Atlanta, Georgia area, we will be presenting the Advanced Sound Quality Seminar in both areas.
The first one will be in College Station, TX (midway between Houston, Austin, and Waco) on January 24, and 25. We will be on the Texas A&M Campus in one of the engineering classrooms for this one.
The second will be in Atlanta, Georgia on February 21, and 22. We have a great conference room in Marietta, GA for this one.
These are both Saturday and Sunday dates.
The seminar is two VERY full days of non-stop, hardcore SQ oriented action, starting at 8:30 AM each day, and we will go until everyone has had their fill.
The Tulsa and DFW seminars in 2008 were excellent! Everyone that has attended will tell you it is worth every minute there, and every dime it cost to attend.
During the seminar, we will detail everything in the outline at the bottom of this post with classroom presentation, many actual demonstrations, and lots of time for attendees to get their hands and ears on the gear for practice sessions. It is a TON of information presented in a format that no other training class can offer, and every bit of it is directly geared towards developing practical application skills and knowledge that can be used when designing, fabrication, and/or tuning high-quality car audio systems.
We've got several different audio reference systems, many different practical demonstrations for setting EQs and crossovers, setting speaker placement, finding and controlling reflections, lots of acoustical experiments, etc. You will not be bored in this class!
We touch on the theory just enough to get deep into what really makes car audio systems sound great. But most of what we teach are practical application skills and techniques. We cover things like the acoustical characteristics of the car's interior, reflections, absorption, speaker placement, all of the electronic tuning issues (EQ, crossovers, delay, etc), and we get into the details of music, and establishing a great audio reference. Again, check out the outline below...
We promise you'll get more out of this seminar in two days than you can find anywhere else in several months, or even years.
The attendance price includes extensive hand out notes, several test CDs, a t-shirt, and some serious tweak and tune time on your car audio system.
The 2009 Competition season is coming up quickly. Now is the perfect time to learn as much as you can, so you can get your system tweaked for maximum performance before the season gets rolling.
Or if you are a judge, you can learn a tremendous amount of great information on what causes an audio system to sound like it does, and be able to provide excellent feedback for the competitor, and be more accurate and consistent when judging. We don't teach specifics about how to score a system (That's for the USACi Judges Training Classes to do...). But we do cover a lot of great information on evaluating and analyzing car audio systems, which can be a tremendous benefit for anyone that evaluates audio systems.
This is a serious seminar for anyone that is truly serious about learning all they can about designing, building, and tuning great sounding car audio systems.
They are both coming up quick, so let me know as soon as possible if you’re interested in attending, either by e-mail reply (meldridge@mblsound.com) or by phone, (918) 810-2535.
Thanks, and hope to see you at one of the Advanced SQ Seminars!

www.mblsound.comAdvanced SQ Seminar OutlineIntroduction and Overview Why Do We Do What We Do???
Workshop Curriculum Overview - What We Will Do in the Workshop
What Really Matters…
The Many Parts of Music Definitions and Terms
Instruments and Vocalists
Amplified and Un-Amplified Performances
Performance Venues: Studios, Clubs, Concert Halls, Etc.
The Emotional Involvement - What is it about the music that gets our blood pumping?
Our Audio Reference The standard with which we compare audio system performance
What is an appropriate reference, and how do we get one?
Live Performances
Live vs. Recorded Music
The Recording and How It Affects What We Hear
The Listening Room and Environment
Near-field, Far-field, Car-field?
The Sound Reproduction System - Studio, Home Audio, Headphone Systems, Etc.
So what is the “perfect” reference system?
Listening Critically to Recordings
Using Our Ears 101 A simple setup to teach yourself how to recognize acoustical problems
Equalization, crossovers, Signal delay, etc.
Comparison of analyzer measurement techniques with adjustments made by ear
Tools, Tools, Tools…… CDs and Software
Acoustical Analyzers: (RTA, TEF, etc) How they work, how to use them, how to interpret the data
Other useful tools – oscilloscope, Radio Shack amplifier, DVM, etc.
Books, Articles, the Internet, and other sources of “information”
Your Ears - Definitely the most important and effective tool in your arsenal!!!!!
Using the Tools Most Effectively
Analyzing the Data
