INTROOUCTION
Your Ashly crossover is the product of an intensive research effort which
combined a re-examination of traditional crossover theory with practical field
testing to prove the new design. Over the past several years, a number of
refinements and new models have been added to our crossover series, but the
original design goals have remained the same: to produce a crossover which is
sonically accurate, is flexible enough to adapt to a wide variety of systems,
and which affords maximum protection for speakers and drivers.
Ashly Audio now manufactures the world's most extensive line of electronic
crossovers for the professional audio industry, from a mono 2-way to our
stereo 4-way, with a choice of either 12dB per octave or 18dB per octave
slopes.
All Ashly crossovers, from the simplest to the largest, are based
upon the same powerful state-variable filter circuit, thus insuring superior
performance from each model. Our crossovers offer a number of useful and
unusual features, including thump-free turn-on without the use of relays, a
damping (rolloff) control that functions much like an equalizer centered right
at the crossover frequency, and a special output stage which maintains. 1 ow
noise
at any level setting. Like other Ashly products your crossover
features low noise and distortion, active balanced inputs, a peak level
indicator, a precision regulated power supply, protection against abnormal
input or output conditions, and rugged mechanical construction. Conservative
design and an unusually thorough procedure for quality control have earned
Ashly
a reputation for dependability in the recording, sound reinforcement,
and broadcast fields.
Due to the similarity of the operating controls on our various crossovers, we
have prepared this one manual to cover all the models in our crossover line.
Specific notes on each model will be found in the Applications section. Many
owners are unaware of the ease with which you can reconfigure your crossover
for non-standard operation. For example, a 4-way crossover can easily be used
as a mono 2-way with sweepable subsonic and ultrasonic cutoff filters, and a
stereo
3-way can function as a mono 5-way crossover. No internal
modifications are necessary, and audio performance is not compromised. These
operating modes are explained in detail beginning on page 8.
In addition, this manual covers normal setup and operation, answers some
frequently asked questions about our crossovers, offers trouble-shooting tips,
and, in a special section, covers basic crossover theory^
Please take the time to read this manual before operating your crossover.
SECURITY COVERS
For installations where it is desirable to protect the front panel controls
from tampering or accidental misadjustment, use the Ashly security cover,
which is available in both single and double rack space sizes. These covers
feature rugged formed and welded steel construction with a clear plexiglass
window
that allows you to see all control settings. Installation is simple
and does not require removal of the equipment from your rack. See your Ashly
dealer for details.
