Here are some interesting videos related to PA and sound reinforcement systems. Wikipedia defines that a public address system (PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. The term, sound reinforcement system generally means a PA system specifically for live music or performance. A sound reinforcement system for a rock concert or other large event in a stadium may be very complex.

Part of the services Stage Left Audio provides is a basic PA. For example, any event that needs just the projection of a voice (and perhaps an instrumentalist).
A basic overview of a 2 x speaker setup for an outdoor wedding ceremony. The PA is for a vocal/instrumentalist only (no band). A wireless mic is used for the officiant, along with a large-format mic for the singers. Guitarists utilized DI boxes for connectivity into the sound system.

“Big Mick” Hughes on Mixing Metallica, Low End, and LEO Line Array
https://www.youtube.com/watch?v=yMV_N1yx0l0
“When you use all the frequencies in the correct proportions, the music sounds full, more powerful, and it does give the impression of being loud.”
FOH engineer “Big Mick” Hughes, who has mixed more than 1,500 Metallica shows, is a legendary figure in live audio.
In this Meyer Sound video, he sheds light on the role of a FOH engineer, his love of low end, and his experience with the Meyer Sound LEO line array system and 1100-LFC low-frequency control element.

Crucial advice for amazing sound-checks in small clubs
https://www.youtube.com/watch?v=nUPIJbBnzk8
Episode #3. After ten years mixing at one of America’s most beloved and well respected live music venues I’m sharing my time-tested, no nonsense methods for fast, efficient, awesome sound-checks. When you’re mixing in small venues where you’ll be mixing both monitors and front-of-house this is good stuff to know to keep things moving quickly while maximizing results and making the performers very happy.
How to Mix Live Music at a Club or Small Concert
https://www.youtube.com/watch?v=fVZ-uCSc9c8
This is a simulated mix strategy – one way to approach a live music mix….I have been doing this since the mid 1990′s and, although it is not a live band, the strategy is the same – even for both analogue and digital consoles. I SHOULD MENTION – that I approach the monitor mix in the same way……add vocals as loud as they go, then add everything else.

1100-LFC: The Meyer Sound Case for Controlling Low Frequencies with Linearity
https://www.youtube.com/watch?v=Mae-Q0ycFVE
With the debut of the new 1100-LFC low-frequency control element, Meyer Sound has extended the advantages of linear sound reproduction to the low frequencies. The goal is to give audio designers a powerful and ultra low-distortion tool to predict, control, and measure the coverage pattern of low frequencies.
“As an industry, we are accustomed to subwoofers carrying a distinct harmonic tone. This ‘sound’ of any subwoofer becomes part of how a product is evaluated. Linear loudspeakers lack this enhancement, and are measured by their ability to precisely reproduce the electronic signals without altering the sonic characteristics.

In Ear Monitoring – Getting It Right
https://www.youtube.com/watch?v=ucC5G4M_4rU
Monitor engineers often struggle with standard monitors to help the artist as much as they need. Over the last few years In Ear Monitors have become a sought-after way for musicians to play live – but it’s not easy to get it right!
Having the sound right in the musician’s ears creates new problems, not the least being making it safe for their ears
The technology also creates problems – you need custom moulds for each musician, as well as for the engineer. The moulds themselves aren’t perfect either, as your ear changes shape whenever you move your jaw, so, for a singer, this means the moulds do not fit perfectly all the time.

Analog Vs Digital Audio Mixers
https://www.youtube.com/watch?v=7JP8K8IQ0ws

Comments:
How about sound quality? Not sure if it’s me but analog sounds better for some reason?
Yes, it sounds naturally warmer and its more unstable (which is a good thing, as it kind of emulates human error and makes it more acoustically pleasing)
But analog mixers don’t have nearly as many options & features, and analog I hear is much more sensitive to electrical disturbances

- poor scheduling of talent
- city bylaws for ‘construction zones’ when setting up stages
Each problem had a workaround.
Live Sound EQ – Ringing Out Feedback VS Flat Response – Q&A Sessions
https://www.youtube.com/watch?v=k_-VqmfOyqE
I am answering some questions that appear on my channel about Live Sound, and other topics. This is about ringing out feedback vs setting a flat response.
$ questions to answer:
1) Is it loud enough?
2) Can everybody hear?
3) Can everybody understand?
4) Will it feed back?
If you ring out feedback frequencies, and make reference materials sound good, the system will be flatter than when you started, but ‘flat’ does not always equal good. The ear is the best tool for assessing sound system quality.

#52 – How To: Handle FAILURES
https://www.youtube.com/watch?v=wNbMepy6e_o
In this video we talk about how to deal with failures on a job without letting it compromise your production.
Comments:
Amen to that. One of the first things on a working day that I will say newcomers: “It’s absolutely fine to make mistakes, everybody does. But, please: speak up if you doubt that you did something right or need help. No one will think of this as bad, but rather good behaviour.”
It really helps, because people feel more safe to admit that they’ve plugged in something wrong, etc. resulting in finding the error much quicker, and move on.
Any specific strategies/coping methods for dealing with microphone failures (wired, wireless, etc)?
Other than being prepared with a backup, equipment failures do happen and you’ve just got to roll with them. I really like how DiGiCo consoles deal with the a/b inputs on each channel, which makes dealing with backups really seamless. Often times, a bit of a chat with the talent about what to do if their mic fails (where the backup is etc) can go a long way to making a failure less noticeable.
This is so true!! Stuff happens all the time

Stage Left Audio – Ringing out monitors
https://www.youtube.com/watch?v=VpeGaUA2728
Reducing feedback in the monitors takes patience and time. Locating the offending frequencies and reducing them (a little at a time) is the process to ring out a monitor system.
The signal path used in this video is: microphone … to board … to aux send out … to EQ in … to EQ out … to amplifier … to speaker.
The principles to ringing out a monitor system can be applied to ringing out FOH; However, FOH EQ settings should be set sparingly.
The “trick” to good sound… familiarize yourself with frequencies.

Pro Sound Speaker Placement
https://www.youtube.com/watch?v=V7OXJ9Ze6d8
This video will cover Pro Audio Speaker Placement, and cover topics such as:
-comb filtering
-power alley
-corner loading
-boundary cancellation
Ratio doubling means:
− a sound pressure level of +6 dB SPL
− a power level of +3 dB
− an electric voltage level of +6 dB
− a loudness level of +10 dB
− 10 dB more SPL means 10 times increase in amplifier gain (amplification)
Unscientifically most people notice a difference of 3db, and 9db is perceived to be twice as loud.
Your main speakers should generally be about 10-15 feet apart. Assuming a 90° horizontal coverage, the speakers should be no further apart than twice the distance between the speakers and the first row of audience members. In other words, if the first row of the audience is 10 feet away from the speakers, the speakers should be no more than 20 feet apart. But assuming a smaller dance floor, if your audience is closer to you than 10 feet, which at most weddings they are, 10 feet apart would cover people dancing 5 feet in front of you. So rather than applying emotional reasoning like “headphone effect”, start applying logical reasoning.
Coupling the subs will get you an extra 6db, 3db from coupling and 3db from having twice the power, theoretically, but closer to a 4.5 db gain.
