HEDD Lineariser®
Due to the physically given relationship between time and frequency, expressed in the
groundtaking harmonic analysis or Fourier transform, different tones have slightly
different travelling times through loudspeakers. This is true for both active or passive
speakers. Broadly speaking, lower frequencies need more time to pass through than
midrange frequencies, and these are slower than the high tones.
Our HEDD Lineariser® offers a complex phase-correction of your HEDD sat-sub
system. It solves one of the most challenging problems in loudspeaker designs, e.g. the
natural occurance of phase difference during multi-component sound reproduction.
With the on-board Lineariser®, our monitors and subwoofers are always “right in time”.
The phase-linearisation will improve transients and imaging. To be noted: the correction
necessarily will introduce a latency of around 30 ms. To avoid the delay that might affect
live recordings or instrument playing the HEDD Lineariser® can be switched off.
