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...
