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 … Read More
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 … Read More
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 … Read More
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 … Read More
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 … Read More
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 … Read More
