Typical Room Layout Surround speakers are typically located two or three feet above ear level, and should not be aimed directly at the mixing position. The amplifiers used for the center and surround channels should be similar to the ones used for the left and right channels. Note that only one amplifier is needed to drive both surround speakers, since the total acoustic output is no greater than in any other channel. Series-parallel wiring, as appropriate should be used. Most trucks have an array of signal processors available, and some are indispensable for proper Dolby Surround production.
Limiters top the list.
Practice has shown that a triple-ganged limiter on the L, R and S inputs to the SEU4 encoder will help control the announcer to crowd ratio during sporting events. A Dolby Surround mixing consultant will be instrumental in sorting out specific processor needs for a given production. Dolby Surround Mixing Consultants Dolby Surround mixing consultants are available to assist with the initial installation of the equipment and to perform the alignment of the encoder, decoder and monitoring system. Instruction on the use of equipment may also be available at this time. Dolby consultants are also available for staff training.
