Alternate Audio EC6

Electronic Crossover



Alternate Audio EC6


In many high performance audio systems, individual drivers are driven by dedicated amplifiers. For such systems, the EC6 offers the following advantages:

  • Elimination of ringing and phase differences between drivers that are introduced by the speaker's internal passive crossover
  • Lower intermodulation distortion
  • Better loudspeaker damping
  • Precise crossover points
  • Reduction of an individual amplifier's required bandwidth
  • Each of these advantages can result in improved sound quality.


    The superior design of the EC6 offers:

    EC6 Back Panel Cascadable design for 2,3 & 4 way crossovers

    User changeable Crossover Modules

    User changeable resistor packs provide flexible crossover points with 24 dB/octave slope

    IEC modules

    Fully fused 120/240 VAC hospital-grade IEC connector

    Binding posts

    Teflon® insulators
    Gold plated connectors

    Other distinguishing EC6 features include:

    • Low noise operation
    • Separate power supply regulation for each channel
    • Critical circuit trace optimization
    • Metal film resistors and polypropylene capacitors in signal path
    • Reversible phase on both low and high pass outputs
    • Summed low pass monural output
