12dB Electronic Crossovers
is designed to fill the needs
of modern high-power sound
systems. Crossover points
land response are continu­
ously adjustable and individual output
stages with wide range gain controls
will drive long cable runs and accu­
rately match any power amplifiers.
All of our 12dB Electronic Cross­
overs use state-variable filter circuits
to perform the frequency divisions.
These filters provide simultaneous
low-pass and high-pass outputs. All
models include inverters on alternate
outputs to keep everything in phase.
A Variable Filter Response control
is included for adjustment of frequen­
cy response in the crossover region,
allowing flat summing. The output
stages have a wide range feedback
level control circuit to maintain an
optimum signal-to-noise ratio at any
setting. A special electronic power
monitor for the output stages pre­
vents turn-on transients without the
use of relays.
Both inputs and outputs can be
used as balanced or unbalanced and
a peak overload circuit monitors all
critical points in the circuit to insure
low-distortion operation.
The logical layout of the control
panels provides an intuitive, "easy-
operation" feel, and LED’s display
peak information. Our entire line of
electronic crossovers, like all Ashly
products, now features our exclusive
five-year worry-free warranty.
