Amcron VFX-2
The Amcron VFX-2 was a dual-channel electronic crossover and filter unit made by Crown International under its Amcron brand. Not much information survives beyond its repeated listing in period professional-audio magazines. The record shows two filters per channel, each continuously variable from 20 Hz to 20 kHz, with a fixed 18 dB/octave rolloff slope. The front-panel controls let the user set each channel for either crossover or band-pass operation. That made it a flexible tool for multi-amplified speaker systems in studio and reinforcement use.
Studio Sound (December 1974, p.22) ran a short advertisement that called the unit a “dual channel crossover/filter” with the specifications above. The same ad ran in later issues through at least April 1975 and listed London stockists REW (Audio Visual) Ltd. That suggests UK distribution, though not necessarily a UK-only release. No dimensions, weight, production years, or original price have been located. The unit appears to have been a compact 19-inch rackmount design, as was typical of the era, but that is inference, not fact.
- Dual channel, two filters per channel
- Frequency range: 20 Hz – 20 kHz (continuously variable per filter)
- Rolloff slope: 18 dB/octave (fixed)
- Functions: crossover or band-pass (switchable)
Beyond these magazine advertisements, almost nothing else is documented about the VFX-2. It was clearly aimed at the same professional users who bought Amcron’s DC-300A amplifiers and 800-series tape recorders. Its production run and final market presence remain unrecorded in the sources available to this archive.
