HEDD Lineariser®
Due to the physically given relationship between time and frequency, expressed in the
groundtaking harmonic analysis or Fourier transform, dierent tones have slightly
dierent 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® oers a complex phase-correction of your HEDD MK2
monitors. It solves one of the most challenging problems in loudspeaker designs, e.g.
the natural occurance of phase dierence during multi-component sound reproduction.
With the on-board Lineariser®, our monitors 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 12 ms. To avoid the delay that might aect
live recordings or instrument playing the HEDD Lineariser® can be switched o.
