Let\u2019s take a quick look at a few topics we get asked about frequently.<\/p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is \u201cFree Loading\u201d?<\/h3>\n\n\n\n<figure class=\"wp-block-image size-medium is-resized\"><img decoding=\"async\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/5\/2021\/05\/sub-corner-01-300x175.png\" alt=\"\" class=\"wp-image-1780\" width=\"500\"\/><\/figure>\n\n\n\n<p>To take advantage of free acoustical power: always place subwoofers on the floor behind the screen \u2013 NOT on a platform with the screen loudspeakers. Floor-positioned subwoofers take advantage of \u201chalf-space\u201d loading, which increases radiated power by about 3 dB, WITHOUT adding any extra amplifier power. <\/p>\n\n\n\n<p>Even better: place the subwoofers on the floor AND push them all the way back against the solid wall behind the screen. That is called \u201cquarter space\u201d loading, and results in about 6 dB greater SPL, without using a larger amplifier. The very low frequencies produced by the subwoofers have no problem going right through any draping or masking below the screen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I Use Standard VGA Cables for Dataport?<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/5\/2021\/04\/dataport.jpg\" alt=\"\" class=\"wp-image-1774\"\/><\/figure>\n\n\n\n<p>It may look like any old VGA video connector, but it\u2019s not.&nbsp;DCA and ISA Series amplifiers and DCP, DCM, and DXP processors use a special QSC connection interface called DataPort. This enables DSP crossovers, loudspeaker-specific EQ, and monitoring and control of amplifier and loudspeaker functions on a single cable. Although many off-the-shelf VGA cables may work with satisfactory results, the QSC DataPort specification requires all 15 pin conductors be present, and all audio I\/O conductors be shielded. Many VGA cables use only 7 pins.&nbsp;If pins 5 or 10 are tied to ground, you may damage the amplifier. Therefore, only QSC supplied DataPort cables should be used.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Screen Channel Loudspeakers &#8211; No Tilt Required<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/5\/2021\/04\/tilt.png\" alt=\"\" class=\"wp-image-1772\"\/><\/figure>\n\n\n\n<p>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.&nbsp;This allows you to minimize the distance from the horn to the screen, and keep it flush within a baffle wall.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Surround Loudspeakers &#8211; What Does \u201cAxisymmetric\u201d Coverage Really Mean?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/blogs.qsc.com\/app\/uploads\/sites\/5\/2021\/04\/axisymmetric.jpg\" alt=\"\" class=\"wp-image-1773\"\/><\/figure>\n\n\n\n<p>All QSC SR Series surround loudspeakers feature Axisymmetric coverage.&nbsp;That means sound is distributed evenly on all axes within the loudspeaker\u2019s defined coverage angle. Unlike many conventional loudspeakers, there is no vertical and horizontal coverage pattern, so aiming is much easier. Up\/down tilt and side-to-side \u201cpan\u201d aiming is all that is needed to cover any area in a cinema.<\/p>\n\n\n\n<p>Feel free to chime in with a question of your own in the comments section below.
