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 … Lire la suite
Five Common Errors in Q-SYS Training Have you experienced our Q-SYS Level One for Cinema training course? If you aced it with the greatest of ease, you are among the few. Less than 5% submit a flawless design for their exit exam. Having graded hundreds of these you can imagine I have a feel for … Lire la suite
Five more ways Q-SYS makes cinema life easier Let’s talk about some potential use cases for the recently released Christie plugin. This discussion won’t cover the entire spectrum of possibilities for the plugin but hopefully it can lay a foundation and maybe inspire some new creative uses. Feel free to utilize the comment section of … Lire la suite
In this blog I’d like to share some of the things that were, at first, confusing to me about Q-SYS. It is specifically for those who are just starting their journey with this incredible, yet intricate and ever-expanding program. Disclaimer: If you are a Q-SYS Super User you might want to skip this blog. It … Lire la suite
We’re only beginning to come to terms with the fundamental changes in many industries in the wake of the global COVID-19 pandemic. While no one can accurately predict the future, one thing is for certain: the cinema exhibition industry will be anything BUT a return to “business as usual”. The pandemic is not the only … Lire la suite
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 … Lire la suite
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 … Lire la suite
In some ways, sound waves are like light waves. They radiate into space, reflect off objects, and lose energy upon contact with absorptive surfaces, walls, and with distance from their source. Sound waves can be more challenging to control, primarily because we can’t see them. Low frequencies are especially difficult because their long wavelengths (up … Lire la suite
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 … Lire la suite
Alternative Methods for Distributing Pre-Show Audio It’s not uncommon to insert some pre-show music into the auditorium to kill the awkward silence before the trailers roll. Classic methods for delivering music to the audience as pre-show filler have been to put a local CD/MP3 player at each auditorium or to have a centralized player and … Lire la suite
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 … Lire la suite
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 … Lire la suite
Take advantage of free acoustical power: always place subwoofers on the floor behind the screen – NOT on a platform with the screen loudspeakers. Floor-positioned subwoofers take advantage of “half-space” loading, which increases radiated power by about 3 dB, WITHOUT adding any extra amplifier power. Even better: place the subwoofers on the floor AND push … Lire la suite
It may look like any old VGA video connector, but it’s not. DCA and ISA Series amplifiers and DCP, DCM, and DXP processors use a special QSC connection interface called DataPort, which enables DSP crossovers, speaker-specific EQ, and monitoring and control of amplifier and loudspeaker functions on a single cable. Although many off-the-shelf VGA cables … Lire la suite
The mid-high frequency section of most 3- and 4-way QSC screen channel loudspeakers has a pre-set downward tilt. When it is properly elevated to approximately 5/8 image height behind the screen and aimed to the last row in a typical stadium-style cinema, there is no need for additional downward tilt. This allows you to minimize … Lire la suite
All QSC SR Series surround loudspeakers feature Axisymmetric coverage. That means that sound is distributed evenly on all axes within the loudspeaker’s defined coverage angle. Unlike many conventional loudspeakers, there is no vertical and horizontal coverage pattern, so aiming is made much simpler. Up/down tilt and side-to-side “pan” aiming is all that is needed to … Lire la suite
