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.

    Äänentoiston varhaiset vuodet
    kirjoittanut J Manninen · 2015 — MS-Audiotron järjesti Messukeskuksessa ensimmäisen audioseminaarin vuonna 1988. Myös alan messutoiminta alkoi yleistyä 1990-luvun

    Täytyypä korjata tähän eräs seikka, tuli nimittäin uutta tietoa Pasilasta… Joenpolven Mikko kertoi lissää detaljeja tosta MS Audiotronin MULTIMIX-mikseristä. Sehän ei ole alkuunkaan Sarapaltion suunnittelema, vaan joidenkin MS:n työntekijöiden jotka nykyään toimivat muissa hommissa.

    LUNDAHL-muuntajat mikki- ja linjasisääntuloissa sekä kaikissa ulostuloissa. Modifikaatiot pudottivat kohinaa melkoisesti, sekä poistivat alussa häirinneen lievän L ja R:n välisen crosstalkin…

    Finally a solution – RED ALERT has proven to be an effective way of preventing DJs running their levels into the red, and is a unique product, we do not know of any other device that is so simple and effective at solving this universal issue.

    When the DJ mixer output goes into the red a big red lamp on the RED ALERT will flash reminding the DJ to take the level back slightly. Simple.

    Live Sound Challenges and Troubleshooting
    Live sound engineering comes with a unique set of challenges that require quick thinking and problem-solving skills to troubleshoot effectively. Here are some common live sound challenges and tips for troubleshooting them:
    Kindly Subscribe to my YouTube: https://youtube.com/@mixedbydrcrack?si=kWIC7KSjQD2ULubg

    1. Feedback:
    – Cause: Microphones picking up sound from the speakers they’re being amplified through, creating a feedback loop.
    – Troubleshooting: Move microphones away from speakers, use directional mics to minimize pickup of ambient sound, apply notch filters to remove specific frequencies causing feedback, and lower stage volume.

    2. Poor Sound Quality:
    – Cause: Room acoustics, improper microphone placement, or EQ issues.
    – Troubleshooting: Adjust EQ settings to compensate for room acoustics, reposition microphones closer to the sound source, and use sound absorption panels to reduce reflections if possible.

    3. Microphone Dropouts or Interference (Wireless Systems):
    – Cause: Frequency clashes with other devices, low battery, or range issues.
    – Troubleshooting: Check and replace batteries, ensure the wireless system is within range, scan for clear frequencies, and coordinate frequencies with other wireless users in the area.

    4. Inconsistent Audio Levels:
    – Cause: Performer movement, varying input levels, or equipment malfunction.
    – Troubleshooting: Use compression to even out levels, instruct performers on proper mic technique, and check for faulty cables or equipment.

    5. Equipment Failure:
    – Cause: Faulty cables, connectors, or hardware failure.
    – Troubleshooting: Keep spare cables and microphones on hand, regularly maintain equipment, and quickly swap out any faulty gear during the performance.

    6. Hum or Buzz in the Sound System:
    – Cause: Ground loops, electrical interference, or bad cables.
    – Troubleshooting: Use DI boxes with ground lift switches, ensure power supplies are properly grounded, and replace any cables that are damaged or suspected to be the cause.

    7. Difficulty Hearing Monitors:
    – Cause: Stage volume too high, poor monitor placement, or inadequate mixing.
    – Troubleshooting: Reposition monitors for better coverage, lower stage volume, and adjust monitor mixes to suit each performer’s needs.

    8. Muddy or Boomy Sound:
    – Cause: Room modes, excessive low frequencies, or poor speaker placement.
    – Troubleshooting: Use high-pass filters to remove unnecessary low frequencies, reposition speakers to avoid bass buildup, and adjust EQ to clear up the mix.

    9. High-Pitched Squealing (Ring):
    – Cause: Specific frequencies are resonating, leading to feedback.
    – Troubleshooting: Use a graphic EQ to identify and reduce the problem frequencies, often referred to as “ringing out” the system.

    10. Vocal Clarity Issues:
    – Cause: Poor mic technique, EQ settings not optimized for speech, or competing frequencies from instruments.
    – Troubleshooting: Instruct performers on proper mic usage, carve out EQ space for vocals, and ensure vocal mics are high-quality and appropriately positioned.

    When troubleshooting, it’s important to remain calm and systematically go through potential causes and solutions. Often, issues can be resolved by simple fixes such as adjusting levels or replacing a cable. For more complex problems, a deeper understanding of the sound system’s signal flow and the specific equipment in use is necessary to identify and rectify the issue.

    In this video, Jazmanaut shows how the Valco VMK25 headphones are equalised in wired passive mode to produce studio headphones with extremely flat frequency response.

    Tällä videolla Jazmanaut näyttää, kuinka Valco VMK25 kuulokkeet ekvalisoidaan langallisessa passiivimoodissa, jotta saadaan äärimmäisen tasaisen taajuusvasteen studiokuulokkeet.
