Kino und Pro Audio: Ein Lautsprechervergleich

Ein Aspekt, in dem sich Kino-Sound von beinahe allen anderen Arten der professionellen Audiowiedergabe unterscheidet, ist die Maßgabe, dass der Klang für alle Kinobesucher so nah wie möglich an der Originalaufnahme sein soll. Dies ist ein wesentlicher Faktor. Filmschaffende wollen, dass wir ihr Werk exakt so erleben, wie sie es bei der Endabnahme ihrer Master-Versionen gesehen und gehört haben. Weiterlesen

DPM = 3 in 1

Bevor der Ton im Kino die Lautsprecher erreicht, muss das Soundsystem drei wichtige Bearbeitungsschritte durchführen, die typischerweise von mehreren separaten Komponenten übernommen werden ... Weiterlesen

Subwoofer ist nicht gleich Subwoofer

Wie unterscheiden sich Kino-Subwoofer von Pro-Audio-Subwoofern? Kino-Subwoofer und Pro-Audio-Subwoofer scheinen auf den ersten Blick recht ähnlich zu sein. Meist sind es große, schwarze Boxen mit zwei 18” Tieftönern. Aber je nach Anwendungsgebiet existieren auch eine Menge Unterschiede. Vergleichen wir doch einmal die Unterschiede zwischen einem Kino-Subwoofer, etwa dem QSC SB-7218, und einem Pro-Audio-Subwoofer, wie unserem GP218sw. Weiterlesen

Six Steps to Great Cinema Sound

We are often asked to design “the best sound system” by a cinema owner. While we appreciate the opportunity to provide audio gear with outstanding performance, great sound requires more than just great equipment. Getting it right requires that you pay attention to each of these Six Steps. Skipping even ONE, will not get you … Weiterlesen

Good to Great

The Cinema industry has been hit hard by the COVID 19 shutdown. While we are optimistic about an eventual recovery, the industry will be changed by all that has occurred. Studio release patterns and theatrical windows are changing. Cinemas need other income streams that don’t rely so completely on major studio releases. Cinemas also need … Weiterlesen

Born to Fly

Most conventional cinema “screen channel” loudspeakers are designed to sit on a platform behind the cinema screen. The low frequency (LF) enclosure is made of heavy MDF panels to offer the best low frequency performance for the lowest cost. The horn section is supported by metal brackets and is mounted to the top of the LF … Weiterlesen

The Power of Multiple Woofers

In a previous blog about loudspeaker sensitivity, we looked at two readily available woofers to see how different specifications and construction techniques resulted in different amounts of low frequency output capability.  For this discussion, we will take a single woofer design and see how using 1, 2 or 4 woofers affects total output capability.  Doubling … Weiterlesen

Cinema Sound at Home

Cinema dealers and customers often ask us which QSC speakers they could use to make a home cinema sound amazing. Many home cinema systems include an Audio Video Receiver (AVR). The AVR is the control center and power amplifier for typical 5.1 or 7.1 home theater sound systems with surround sound. The AVR contains 5 … Weiterlesen

Series versus Parallel Surround Wiring

Have you ever wondered which is a better method for wiring your surround speakers, and why?Some installers use Series-Parallel wiring schemes to conserve amp channels and raise load impedance on inferior amps. But at QSC, we have always recommended parallel wiring for all surround speakers when multiple speakers are combined on an amp channel. Parallel … Weiterlesen

Sensitivity Sensationalism (Part 2)

In our previous blog post, Sensitivity Sensationalism, we looked at some incorrect assumptions often made around loudspeaker sensitivity and power ratings. We discussed the dangerous practice of publishing inflated specifications, including frequency range, power handling, impedance, and unspecified boundary loading conditions. And we promised a deep dive into the design of a Screen Channel Low … Weiterlesen
