With COVID restrictions significantly eased, the Committee has made the decision to trial some in-person events as well as to maintain some online events for the 2022 meeting calendar.

On Monday April 11^th a small cohort gathered in person for the first time in over two years for a Section Meeting. We visited the Involve Audio facility at Mentone, where Charlie Van Dongen demonstrated his designs for the complete surround sound chain with improved soundstage imaging – decoding, amplifier, loudspeaker processing, as well as electrostatic loudspeakers.
