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...
