These filters provide simultaneous

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, "easyoperation" 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.
