Package Contents; Most Common Applications And Listening Distances - Klein + Hummel O 300 Operating Manual

Introduction
Thank-you for purchasing a Klein + Hummel loudspeaker. A Mathematically Modeled Dispersion™ waveguide
(MMD™), flexible acoustical controls, various input options and an extensive mounting hardware range allow the
loudspeaker to be used in diverse acoustical conditions, with any source equipment and in a wide variety of
physical locations. The latest acoustical and electrical techniques and components have been used to ensure the
most accurate sound reproduction possible. Klein + Hummel products are designed for longevity so we hope you
enjoy many happy years of using this product.
Depending on the size, Klein + Hummel's three-way systems are designed for use as near field monitors through
to large main control room monitors. They can be used in music, broadcast, and post production studios for
tracking, mixing, and mastering. They may be positioned free-standing or flush mounted into a wall, and can be
mixed freely in multichannel systems.

Most Common Applications and Listening Distances

The minimum, recommended, and maximum listening distances are shown below, together with their most
common application:
Product Most Common Application
O 300 (D) Near-field monitoring
In multichannel systems, one should ideally use the same product for all main channels. However, as the rear
channels often contain less bass and the signals are mixed at a lower level than the front channels, the rear
loudspeakers can be smaller - table below for details. The center loudspeaker should always be of the same type
as the left and right loudspeaker. The subwoofer should be sufficient to keep up with the main loudspeakers
- see subwoofer operating manual for details.
