Products   : :   Electronic Crossovers   : :   Resolution Series FM 330

  • Truly unique Class A crossovers with unique linear-phase 36 dB/octave attenuation

  • Unmatched accuracy & reproduction, far superior to any other crossover

  • Perfect step response with absolute freedom of overshoot and ringing

  • 90dB (!) attenuation = reduced intermodulation distortion of speakers

  • Lower distortion of drivers thanks to reduced diaphragm excursion

  • No speaker lobing irregularities thanks to perfect in-phase response

Unique performance: the FM 330 Series
2-way, 3-way and 4-way Electronic Linear-Phase Crossovers
  • Discrete balanced Class A input featuring a CMRR of >90dB!

  • Proprietary, precision Linear-Phase filters

  • No IC's, hybrids, op-amps, or transformers anywhere in the audio path

  • Pure discrete "enhanced Class A" circuitry throughout; no feedback, nor feedforward

  • Separate crossover frequencies for low-pass and high-pass filter

  • Massive improvements of multi-way systems are now possible simply by replacing the existing crossovers in a mutli-way system

  • Ultra-precise crossover frequencies are easily adjusted via plug-in modules on frontpanel

  • Automatic output muting

  • The superb discrete Class A balanced output buffers sense the load and automatically optimize the interface to any power amplifier, be it balanced, pseudo-balanced or unbalanced

  • Unique outputs modules drive longest cables (>200m), including high capacitance and inductance with absolute stability

  • Up to +27dBu (50Vpp) output capability and 10dB channel gain allow very high output drive voltages = superb signal to noise ratio of system

  • Delayed turn-on circuitry avoids switch-on transients, thumps and instability

  • Groundlift feature; ground and earthing problems are avoided
