FM Acoustics
FM 330
  • Truly singular 3 and 4-way crossovers with unique linear-phase 36 dB/octave attenuation 

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

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

  • 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

  • Discrete balanced Class A input circuits provide ultimate rejection of hum, noise, interference etc. (100-1000 times better than other so-called balanced equipment). 

  • 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 feed-forward

  • Separate crossover frequencies for low-pass and high-pass filter. Any crossover frequency between 60 Hz and 16 kHz is available. 

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

  • Automatic output muting

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

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

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

  • Groundlift feature; ground and earthing problems are avoided

  • and much more...
