The Design of Active Crossovers

By Douglas Self

The layout of lively Crossovers is a special consultant to the layout of top of the range circuitry for splitting audio frequencies into separate bands and directing them to various loudspeaker force devices in particular designed for dealing with their very own diversity of frequencies. characteristically this has been performed by utilizing passive crossover devices outfitted into the loudspeaker bins; this can be the best answer, however it can also be a package deal of compromises. The excessive fee of passive crossover parts, and the ability losses in them, signifies that passive crossovers need to use rather few components. this boundaries how good the crossover can do its simple task.

Active crossovers, also known as digital crossovers, take on the matter in a way more subtle demeanour. The department of the audio into bands is played at low sign degrees, ahead of the facility amplifiers, the place it may be performed with a lot larger precision. Very subtle filtering and response-shaping networks should be outfitted at relatively reasonably-priced. Time-delay networks that atone for phyical misalignments in speaker development should be applied simply; the similar in a passive crossover is impractical due to the huge expense and the heavy sign losses. lively crossover expertise can also be without delay acceptable to different band-splitting signal-processing units akin to multi-band compressors.

The use of energetic crossovers is expanding. they're utilized by nearly each sound reinforcement process, through nearly each recording studio tracking set-up, and to a small yet growing to be quantity in family hifi. there's a turning out to be popularity within the hifi that multi-amplification utilizing lively crossovers is the most obvious subsequent step (and most likely the final giant one) to getting the very best sound. there's additionally a wide utilization of lively crossovers in vehicle audio, with the emphasis on routing the bass to huge, immense low-frequency loudspeakers.

One of the only a few drawbacks to utilizing the lively crossover process is that it calls for extra energy amplifiers; those have frequently been outfitted into the loudspeaker, in addition to the crossover, and this deprives the client of the opportunity to settle on their very own amplifier, resulting in resistance to the complete lively crossover philosophy. A entire thought for fixing this challenge is a vital a part of this book.

The layout of lively crossovers is heavily associated with that of the loudspeakers they force. A bankruptcy offers a concise yet whole account of all of the loudspeaker layout matters that impact the linked lively crossover.

This ebook is packed jam-packed with helpful info, with nearly each web page revealing nuggets of specialised wisdom by no means prior to released. crucial issues of concept relating useful functionality are lucidly and carefully defined, with the math stored to an important minimal. Douglas' historical past in layout for manufacture guarantees he retains a cautious eye at the expense of things.


  • Crossover fundamentals and requirements
  • The many various crossover varieties and the way they work
  • Design nearly any type of energetic clear out with minimum mathematics
  • Make crossover filters with very low noise and distortion
  • Make high-performance time-delay filters that provide a continuing hold up over quite a lot of frequency
  • Make a large choice of audio equaliser phases: shelving, peaking and notch characteristics
  • All approximately lively crossover method layout for optimum noise and dynamic range
  • There is a big volume of recent fabric that hasn't ever been released earlier than. a number of examples: utilizing capacitance multipliers in biquad equalisers, opamp output biasing to lessen distortion, the layout of NTMTM notch crossovers, the layout of detailed filters for filler-driver crossovers, using combined capacitors to lessen filter out distortion, differentially increased inner degrees to minimize noise, and so on.

Douglas wears his studying calmly, and this publication beneficial properties the enticing prose type general from his different books The Audio strength Amplifier layout Handbook, Self on Audio, and the new Small sign Audio Design.
