100W Audio Bi-Amplifier, w/ Linkwitz-Riley Crossover - Unbalanced Input [XAMP-M3]

  • $ 5395


Bi-Amping your speakers is the most powerful, low cost, and simplest way for audio enthusiasts to enter the realm of true audiophile quality.

  • 2-way active cross-over drives dual on-board power amplifiers separately drive the woofer and  tweeter
  • All Analog Design
  • Linkwitz-Riley crossover, 4th order, 24dB/Octave
  • Uses two highly respected LM4766 amplifier chips in bridged configuration to produce 100W peak on both woofer and tweeter
  • Crossover frequency configuration components are located on a single socketed module – it’s very quick and easy to change the XO frequency by simply snapping in a new module.
  • We offer a wide range of standard XO frequency modules. Simply select your desired XO frequency from the drop-down menu above
  • Supports Baffle Step Compensation (BSC). The BSC gain is adjustable and the frequency is configurable to support various baffle sizes
  • Channels are phase aligned to within a fraction of a degree to minimize distortion at and around the XO frequency
  • Separate bass and treble output gain adjustments via precision multi-turn trim-pots
  • Low power consumption and no negative supply needed - perfect for portable battery powered speakers
  • Quiet power ON / power OFF
  • This is a mono device, two units are needed for stereo operation
  • This is an intermediate electronic kit containing 85 components, and can be assembled in about 1-2 hours

    What is Bi-Amping? It is the replacement of your speaker’s passive crossover, a source of audible distortion of your sound, with a precise Active Crossover placed ahead of your power amps. The power amplifiers drive the woofer and tweeter directly with no passive components getting in the way. The result is nothing short of breathtaking. You’ll hear detail and color in your music you’ve never heard before. The sound stage opens wide in all dimensions, and you can picture every instrument as if it was in the room with you.

    One of the most important specs for an active crossover is phase coherence. This is the alignment in time of the high and low outputs. If these are out of phase, sounds that are at or near the crossover frequency will be significantly distorted, because both the woofer and tweeter are both driving at this frequency, and if the channels are out of phase they will each be creating slightly different sound, which creates distortion. This video shows how precisely our channel phases are aligned:
