Videos about big audio systems

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.

    A look inside one of Rupert Neve’s greatest inventions, the diode compressor. The 33609 is the same 2254 compressor from Neve’s 80-series consoles, but with a class AB signal path and in rack mount format.

    1176 FET Compressor Teardown pt 1: Circuit and Compression Secrets

    What gives the 1176 compressor design it’s incredible staying power? I take apart a Hairball Audio 1176 Rev D to show what’s under the hood. There are some surprising discoveries along the way, such as:

    - a single $0.50 FET is responsible for most of the sound
    - there *is* a threshold control (if you know where to look)
    - the ratio control is a lie?!

    The LA-2A’s Underrated Little Sibling? Urei LA-4 Opto Compressor teardown

    The LA-4 gets constantly outshone by it’s older siblings, the LA-2A and LA-3A. But today it gets to step into the stoplight with a DIYRE teardown. Check out why I think the LA-4 is an underrated gem that deserves more attention.

    Viewer comments:

    This piece of gear was designed for installation and studio use. Most of the time it’s hard wired into a patchbay or stationary system. So so xlr connectors would have been an extra expense and failure points. You can always add them on a pigtail or rack panel for portable use.

    DIY Recording Equipment EQP5 passive EQ build
    https://www.youtube.com/watch?v=-YlKyCDPHg4

    This 500-series equalizer is based off the famed Pultec passive EQ: the EQP-1, which was originally released in 1951 by Pultec (Pulse Techniques). The kit came with all parts, and wasn’t difficult considering the great build guide and tools on the DIYRE website.

    The PCB is thick, and the pads are through-hole (so no need to solder both sides – bottom only!). All parts were grouped in small baggies (actually wish they had used less bags, it ended up being a lot to throw out), so sorting parts was quick and painless. The hardware was equally robust, and once assembled it feels quite solid.

    The bass is so strong that the space around the speaker is literaly distorted

    The Biggest Sound System Set up in the World,Team Stroker Part two 50 percent of testing
    https://www.youtube.com/watch?v=vijS6buNVzU

    The battle of distortion. Sound should be judge by the quality of low mid high at high and low volume. Mostly local sound systems are judged by the loudness and strongest power of bass which usually sound distorted. Based on my experienced watching live big musical events & concerts like Tomorrowland, Ultra Music Festival Miami, Coldplay, Bon Jovi, Metallica, Journey, Michael Jackson, GNR etc the sound is very clear and clean at very high and loud volume.

    That is quality sir….. The loudness of vocals is good that is why it is on top…….. The sub is like bomb

    I highly doubt it’s 800,000 watts, maybe 80,000 watts but not 800,000..

    800,000 watts ……for that tiny pa?
    I miss the good ol days where the pa was so big it obstructed part of the stage if you were in the rite place…..I mean come on, 800,000 watts …to power that crappy sounding cheap pa system?

    Sinai is one of the UK’s most versatile sound systems. Deep Medi, Tectonic Recordings and Young Echo are some of the labels and collectives to have hosted the roaming Sheffield audio installation, which bridges the gap between traditional dub sound system culture and modern bass music.

    Founded by Huw Williams, Sinai Sound System began life as part of the travelling speaker stack for legendary dub outfit Iration Steppas. Over the years, Sinai has grown in size and reputation, travelled the continent and endured a devastating flood in its hometown.

    In this film, FACT travels to Sheffield to hear the story of Sinai Sound System and follows it to Bristol’s Trinity Centre as it prepares to provide the audio at the fifth birthday party for Batu’s Timedance label.

    Summing Shmumming? Analog vs digital summing test

    In which I finally tackle the issue of analogue summing: is this the secret magic ingredient thats been missing from your ITB mixes? Or, are we being conned by charlatans and snake oil salesmen? Lets find out…

    Viewer comments:

    This kind of ,,myth busting” is just what the audiophile and music industry needs. So many people get emotionally invested into things like their gear, or the way they play, compose, mix… And they can end up leading others away from the path of reason and into marketing potholes, and ignorance ditches. Good work, Dan! Thanks for making those experiments, so that we don’t have to (although I would encourage anyone with enough time and equipment to go for it) ! Cheers!

    It’s impossibly bad in guitar circles, the cognitive bias is unstoppable. Yeah sure that 59 ‘burst is worth $350000 compared to the damn near perfect reproduction from another brand name…sure.

    There’s that old trick, where you do an A/B test between one audio example (like a full song or drum mix), and another which is secretly raised .5 dB. You then ask the subject which they think is better and why. Most often you’ll get a response like “B sounds more open, wider, brighter; objectively better”, just from that tiny lift in level. And what do you know, that’s how audiophiles describe why they spent 4 stacks on a power cable

    VOCAL EQ SECRETS of the PRO’s
    https://www.youtube.com/watch?v=Wq1di2luMcs

    Took some notes on this thought should share with everyone:
    - Always cut below 100 hz
    - 100 hz is low end, by boosting it can give deep rumble, radio warm kind of vocals.
    - Boosting 200 hz is warmer point where vocal body lives.
    - 300 hz to 500 hz is where boxiness and Honkiness comes. Its not a good idea to boost it but reduce.
    - 600 hz to 1 khz is the point where body lives, its not a good idea to boost or reduce it
    - 1.5 khz to 2.5 khz is where actually vocal is, by boosting vocals can pop up by reducing vocals can disappear. Boosting too much can boost nasal sound.
    - 2.5 khz to 3.5 khz is a proper nasal sound frequency range if the vocal has nasal sound cut it down.
    - 4 khz is harshness, too much boosting can be harsh too much cutting can make words less understandable.
    - 6 khz is clarity, cutting it down can make vocal warm.
    - 7 to 10 khz is where siblance comes.
    - 10 to 16 khz top end sizzle.
    - 17 khz to 20 khz air and breath.
