RUNNING-IN
When new, PMC monitors require a short period of running-in before they
reach their full potential. This is because the mechanical and acoustical
characteristics of the bass, midrange and treble drive units alter slightly after
manufacture as the flexible elements in their construction relax and reach
their optimum compliancy. The ATL
designed to load the bass driver accurately only when it has reached its
long-term, optimal compliancy.
Consequently, during the initial running-in period of about 50 hours, the
performance of the monitor will change and improve. You will notice the
bass tonality becoming warmer, fuller, and more natural, and the bass
extension will increase significantly. As the tweeter relaxes the treble tonality
also sweetens and integrates perfectly with the midrange unit, and the
sound staging becomes vivid.
