1. INTRODUCTION
Your ASHLY crossover is the product of an in-
tensive research effort which combined a reexamination
of traditional crossover theory with practical field use.
Over the 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 cross-
over which is sonically accurate, is flexible enough to
suit a wide variety of systems, and affords maximum pro-
tection for speakers and drivers.
All Ashly crossovers are based upon the same
powerful state-variable filter circuit, which guarantees that
two adjacent frequency band outputs always remain in
phase. Our crossovers offer a number of useful and un-
usual features, including continuous tuning, a response
control, and a unique output stage which maintains low
noise at any level setting. These models also include a
200:1 tuning range, output mute switches, and both TRS
and XLR connectors. Like other Ashly products, your
crossover features low noise and distortion, active bal-
anced inputs, a peak level indicator, a precision regulated
power supply, protection against abnormal input or out-
put 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 models, we have prepared this one manual to
cover our complete crossover line. Specific notes on each
model will be found in separate application notes. Many
owners are unaware of the ease with which you can
reconfigure your crossover for nonstandard operation. For
example, a 4-way crossover can easily be used as a mono
2-way with tunable subsonic and ultrasonic cutoff filters,
and a stereo 3-way can function as a mono 5-way cross-
over. No internal modifications are necessary, and audio
performance is not compromised. In addition, this manual
covers normal setup and operation and offers troubleshoot-
ing tips. Please take time to read it before
operating your crossover.
2. UNPACKING
As a part of our system of quality
control, every Ashly product is carefully
inspected before leaving the factory to en-
sure flawless appearance. After unpacking,
please inspect for any physical damage.
Save the shipping carton and all packing
materials , as they were carefully designed
to reduce to minimum the possibility of
transportation damage should the unit again require pack-
ing and shipping. In the event that damage has occurred,
immediately notify your dealer so that a written claim to
cover the damages can be initiated.
The right to any claim against a public carrier
can be forfeited if the carrier is not notified promptly and
if the shipping carton and packing materials are not avail-
able for inspection by the carrier. Save all packing mate-
rials until the claim has been settled.
3. AC POWER REQUIREMENTS
Unless otherwise indicated on the back of the
unit, all crossovers should be connected to a 3-wire
grounded outlet supplying 120 Volts, 50-60 Hz. Some
export models are 240 volts, and are labeled accordingly.
This unit will perform normally from 92 to 130
volts AC. A “brownout” condition occurs when avail-
able AC power falls low enough to take the unit’s DC
power supply out of regulation, increasing noise and low-
ering signal headroom. In general, avoid powering your
audio system with AC circuits that additionally run large
refrigeration compressors, air conditioners, electric heat-
ers, lighting systems, etc.
This unit has an internal line fuse. In the un-
likely event that the fuse should blow, refer the product
to a qualified service technician. Power consumption is
15 watts.
4. 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. In-
stallation is simple and does not require removal of the
equipment from your rack. See your Ashly dealer for de-
tails.

To allow a wider tuning range, our crossovers use
a recessed range switch for each frequency control. LED
indicators provide range status as soon as the unit is pow-
ered on. The range switch divides the frequency indi-
cated on the frequency control by 10 and gives a total
range of 200:1 for each control. Avoid accidental dam-
age to speakers by muting the outputs before changing
the range switch. Carefully plan and check the frequency
range selected to each driver before sending audio sig-
nals to your speakers.
The choice of crossover frequencies depends on
the type of speakers being used, personal taste, room
acoustics, and many other factors. Experiment to see what
works best for you.
CAUTION: High frequency compression driv-
ers may be destroyed by the use of too low a crossover
frequency. Follow the driver manufacturer’s recommen-
dations carefully. Make sure the range switch is properly
set. You may want to install a security cover if the unit is
accessible to untrained people.
5.4 Response
This control, found adjacent to the crossover fre-
quency control, adjusts the damping of the filter affect ing
the response shape of the filters at the crossover poin t (see
drawing). The dial calibrations refer to the amount of at-
tenuation effected by the filter at the crossover frequency,
i.e., a setting of 3dB means that the filter’s high-pass and
low-pass outputs are each “rolled off 3dB at the crossover
point”. This describes Butterworth filter response, or a
gentle 3dB peak at the crossover point when the two filter
output signals overlap. To obtain a flat signal, or
“Linkowitz-Riley” response through the crossover region,
set the Response control to “6”. This attenuates each out-
put of the filter by 6dB at the crossover point (two identi-
cal signals added together yield a +6dB increase). To ob-
tain a notch at the crossover point, turn down the response
control past “6” to best suit your needs.
5. CONTROLS
EveryAshly crossover has the following controls:
a Power Switch, an Input Level control, a Crossover Fre-
quency (Hz) control and Range Switch for each dividing
point, a Response (dB) control, Output Level controls
with Mute Switches, and a Peak Indicator LED. The
XR1001 and XR2001 also have a Mode Switch for se-
lecting between 2-way and 3-way operation.
5.1 Power Switch
This switch connects AC power to the rest of the
unit. You will know power is on when one of the cross-
over frequency range LED indicators is lit. If there is no
light, check to see if the unit is plugged in to a live out-
let. If there is still no light, the internal AC line fuse may
have blown. Refer the unit to a qualified service techni-
cian for fuse replacement.
5.2 Input Level
This control can boost incoming signal up to
+8dB before it reaches the filters, or attenuate the signal
so that it is fully off. Maximum input level is +23dBu.
The “U” shown at the 12:00 position indicates “unity gain”
of the input section. We recommend setting this control
at unity and controlling system levels either prior to the
crossover or at the output level controls.
5.3 Crossover Frequency
This infinitely variable control allows you to se-
lect an appropriate crossover point for your speakers.
Turning the knob clockwise moves the crossover point to
a higher frequency, while turning it counterclockwise
moves it to a lower frequency. Crossover frequencies are
marked on standard ISO 1/3 octave center frequencies
with each octave calibrated. Calibration accuracy is very
good, typically within 1/3 octave or better. If greater
accuracy than this is necessary, measure the actual cross-
over frequency with an accurate oscillator/frequency
counter.

Operating Manual - XR1001, XR2001, and XR4001 Electronic Crossovers
The purpose of this control is to help offset the
inaccuracies inherent in typical loudspeakers, thereby
helping you to achieve a flat system response. If you use
a spectrum analyzer to set up your system, adjust the re-
sponse control to obtain the flattest response through the
crossover region before any equalization is applied to the
system. If adjusting by ear, we recommend an initial set-
ting of 6dB. Adjust from this point if the system appears
to have an excess or deficiency of level at the crossover
point. NOTE: The Response control is not a “slope”
control. A12dB/octave crossover will always have a slope
of 12dB/octave regardless of the setting of this control.
Likewise, a 24dB/octave crossover will always have a
slope of 24dB/octave. The Response control only affects
filter response shape in the immediate vicinity of the cross-
over frequency; the ultimate crossover slope is a fixed
parameter.
5.5 Output Level
The crossover’s output stage operates at unity
gain with the output level controls set at “U”. Max gain
of the output stage is +15dB. In a typical setup, power
amplifier input level controls should be run “full-on”, with
level control being accomplished at the crossover. Adjust
the crossover level controls for best system balance. Keep
in mind that in any multi-amplified system, the higher fre-
quency speakers tend to be more efficient. Expect to run
the higher frequency level controls at a somewhat lower
setting than the low frequency level controls to obtain
proper frequency response. Note that horn and compres-
sion driver combinations are much more efficient than cone
speakers, often by 12 to 20dB! When cones and compres-
sion drivers are used together, you should expect a much
lower level setting for the horns (all other factors being
equal) to compensate for this difference and obtain proper
balance.
Output Mute switches allow you to isolate indi-
vidual or grouped outputs for listening tests without af-
fecting the settings of any other outputs.
5.6 Clip Indicator
Ashly crossovers feature a peak detection circuit
which monitors signal level at several critical points in
the crossover: input, filters, and outputs. The LED will
flash when signal levels of +20dBu are reached anywhere
in the crossover. Since our crossovers have a nominal
23dB of headroom referenced to a standard operating level
of 0dBu (.77 Volts), a flashing LED warns you that you
are only 3dB from clipping.
Since peak levels are monitored at several key
circuit points, the clip LED can be used to isolate the
source of any overload. If the LED flashes even though
all input and output levels are turned down, the signal
being fed to the crossover is excessive. If the LED flashes
when you turn the Input level control up (with the out-
puts still turned down), the overload is occurring in the
filter sections, and you should back the Input level down
a bit. If the LED first flashes when you turn the output
level controls up, then the overload is occurring in the
output stage. In this case, if your power amplifier con-
trols are at full gain, you are probably severely overdriving
your amplifier.

6. AUDIO CONNECTIONS AND CABLES
6.1 Balanced
Your crossover is provided with two different
connector types, wired in parallel. 1/4 inch stereo phone
jacks and three pin XLR type connectors will allow inter-
facing to most professional audio products, with pin 2 hot
(+) and pin 3 (-). The inputs and outputs can be used ei-
ther balanced or unbalanced. We recommend balanced
connections between all components in your system, as
this minimizes ground-loop or induced hum and noise.
6.2 Unbalanced
If either inputs or outputs are used unbalanced,
the signal is on the (+) connection and the (-) connection
must be tied to ground. A mono phone plug used as an
unbalanced connection will automatically ground the ring
of the jack which is the (-) connection. When using a ste-
reo plug or XLR connector for unbalanced input or output
connections, the signal (-) MUST be tied to ground, or
loss of signal level may result.
6.3 Inputs
Inputs are 20KΩactive balanced, or 10KΩun-
balanced.
6.4 Outputs
The outputs on Ashly crossovers are low imped-
ance (200 ohms typical) pseudo-balanced type using both
a 3-pin male XLR connector and standard 1/4" phone jack.
Pseudo-balanced lines, while not carrying a truly differ-
ential signal, have an equivalent line impedance on both
(+) and (-) lines. This allows for long cable runs from the
crossover into balanced inputs without compromising
common mode rejection of unwanted noise. To realize
maximum headroom, terminate outputs into loads of 600
ohms or greater.
6.5 Mono Low Output
Ashly models XR2001 and XR4001 have an ad-
ditional jack labeled MONO LOW OUT. This output rep-
resents the sum of low frequency outputs of both chan-
nels, and is a function of BOTH low level controls. It is
typically used for driving mono sub-woofers in a stereo
system, reducing the number of power amps needed. Con-
nectors and wiring are the same as the other outputs. If
you are using a mono low output, you may also use the
normal low frequency outputs to drive other speaker sys-
tems; any or all of the low frequency outputs may be
used at any given time without interaction between out-
puts.
6.6 System Phase
The outputs of all Ashly crossovers are in phase
with the input. Assuming that your power amplifiers do
not invert phase (most do not), the signals from all your
amps should be in phase. If all speakers are the same
brand, it is easy to keep them in phase. With different
brands of speakers used together, phasing becomes a little
more confusing. It is important to keep all the speakers
within each band in phase with each other, and equally
important to keep all bands of the system in phase as well.
If this is not done, loss of level and pattern control at the
crossover frequency will result.
Phase of CONE speakers can be checked by con-
necting a 1.5 volt battery to the speaker and observing
which way the cone moves. Don’t try this with compres-
sion drivers! The most common convention is that (+)
voltage on the (+) terminal moves the cone forward. A
notable exception to this convention is JBL. A (+) volt-
age on the red terminal of a JBL speaker moves the cone
backward. If all your speakers are the same brand, just
connect them all the same way; if not, it’s best to test.
Unfortunately, compression drivers cannot be tested this
way. Ask the driver manufacturer.

8. TROUBLESHOOTING TIPS
8.1 No Output
CheckAC power - are LED indicators on? Check
in/out connections, are they reversed? Are you
sure you have input signal?
8.2 Peak light flashes frequently
The level is too high somewhere in the cross-
over. Try turning down individual output levels
and then the input until the peak LED stays off.
If the peak LED continues to flash when all of
the crossover level controls are turned down, then
the crossover is being fed excessively high lev-
els from a previous piece of equipment. Turn
down your driving source!
8.3 Distorted sound
Is the peak light flashing? If it is, an overload is
occurring within the crossover, and may also be
occurring in other parts of the system. If the peak
light is not flashing, the distortion is occurring
somewhere outside the crossover.
8.4 Excessive hum or noise
Hum will usually be caused by a “ground loop”
between components. Try using the suggested
balanced input and output hookups if the other
pieces of equipment used in conjunction with your
crossover have balanced inputs and outputs.
Noise can be caused by insufficient drive signal.
Ashly crossovers provide the best noise and head-
room performance when the input signal is 0 to
+4dBu level and power amplifier sensitivity is
higher than 1 volt. Unshielded cables, improperly
wired connections, and cable with broken strands
(shorts, etc.) are the most common problems.
Please properly maintain and inspect your wiring
first.
