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

Cinema Sound for Small Rooms (Part 3)

In this third and final installment of our look at small rooms, we’ll focus on Q-SYS and how it can be used for multi-room systems, especially “cinema on demand” rooms in commercial multiplex sites. As before, let’s look at room sizes of about 10m, or 33 ft. in length. We’ll also assume the use of … Weiterlesen

Sensitivity Sensationalism

Loudspeaker sensitivity and power ratings have become the primary specifications used to design sound systems in cinema. This practice and these specifications are accepted at face value and not often questioned. They make designing sound systems fairly easy and straightforward. However, they rely on many assumptions and some of them are simply not valid, at least … Weiterlesen

Cinema Sound for Small Rooms (Part 2)

In Part 1 of our discussion on small rooms, we focused on premium solutions using our Reference Monitor System. In Part 2, we will look at some systems using the economical DCS SC 1120 and SC 1150 screen channels and a variety of amplifier and processor options for small rooms, including private screening rooms, high-end … Weiterlesen

Cinema Sound for Small Rooms (Part 1)

In addition to our larger audio solutions for mainstream multiplexes, QSC has several options for small rooms. These could be private screening rooms, high-end home cinemas, or even “cinema on demand” rooms in multiplex sites that are rented to small groups. While QSC can support all room sizes, let’s focus on rooms of less than … Weiterlesen

Aim to Please

The best speakers in the world are not going to sound great if they are not located in the proper position and aimed correctly at the audience. The goal of a cinema sound system is to provide the best possible sound to a large number of people.  Each seating location should have a similar audio … Weiterlesen

An Inside Look at DPA-Q

Discover the power and flexibility of the new DPA-Q amplifier series Q-SYS – our ecosystem for audio, video, and control – combined with our new DPA-Q amps, has become increasingly popular for powering immersive audio systems in Premium Large Format cinemas. In this post, we’ll show you how you can use our new 8-channel DPA-Q … Weiterlesen

DCA Amps Done Right!

Setting up DCA amps with QSC DataPort processors and DCS Series Loudspeakers is fast and easy because a single HD-15 cable carries all connections between the amplifiers and processor.  Dual channel audio input, control of AC standby mode, amplifier output monitoring and even impedance measurement of loudspeaker loads are all accomplished via a single DataPort cable … Weiterlesen

9 Reasons Your Subs May Be Failing

Subwoofer failures have several causes.  Repeated failures indicate that there is something wrong with the application or the installation. Simply replacing woofers will not fix the underlying problem.  Well-designed, high quality subwoofers should not fail.  Check the following things to find the real issue. 1. The room is too big. Another way of saying this … Weiterlesen
