Improvements to the sound reinforcement in the auditoriums, whose 10-15-year-old speakers are in need of renewal, have been made possible and worthwhile due to technical progress. The chosen solution is the colinear <a rel=\"noreferrer noopener\" href=\"https:\/\/www.l-acoustics.com\/en\/product\/syva\/\" target=\"_blank\">Syva<\/a> from L-Acoustics; this will be tested more thoroughly in three auditoriums starting in the autumn semester and, if these tests are successful, will be successively installed in all of ETH&#8217;s auditoriums.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><sup>*<\/sup> In the context of A\/V equipment, a &#171;shootout&#187; is the direct comparison of technical systems to assess their quality under conditions that are as realistic as possible.
