VFX-2
The CROWN VFX-2 is a dual-channel variable electronic
filter-crossover. When used with a power amplifier it can
greatly add to the total system capability. In combination
with the
DC-300A,
the VFX-2 adds several convenient
useful functions.
The connections are made with the VFX-2 quickly and
easily. If a balanced line is to be used with the unbalanced
input of the DC-300A. the VFX-2 can serve asthe interface.
While maintaining these functions the output can be
shaped by selecting variable high-pass, lo-pass, or
band-
pass filters. As a filter, the VFX-2 can be used as a cross-
over or ahead of several amplifiers in a bi- or
tri-amped
system.
Overall noise and distortion are extremely low, with IM
distortion less than .Ol% at rated output (2.5V into 600
ohms), and noise more than 1
OOdl3
below rated output with
OdB
gain.
