APPLICATION NOTE NO. 3
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.
First, the DC-300A can be used as a mono amplifier with-
out internal modifications. 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 as the interface. While maintaining these functions
the output can be shaped by selecting variable high-pass,
31
lo-pass, or band-pass filters. As a filter, the VFX-2 can be
used as a crossover or ahead of several amplifiers ina bi- or
tri-amped system.
Overall noise and distortion are extremely low, with IM dis-
tortion less than .01% at rated output (2.5V into 600 ohms),
and noise more than 100dB below rated output with OdB
gain.

tion sheet or for a nominal fee, purchase a VFX-2 instruc-
