Safety and Operation Precautions.
1. Heed all warnings; follow all instructions.
2. Refer all servicing to qualified personnel.
Servicing is required when the apparatus has
been damaged in any way.
Installation and Mounting
3. To prevent inductive effects from causing
hum and/or noise, loudspeaker lines should
not be laid together with other electric
cables, microphone or line level signal
cables connected to amplifier inputs.
4. To ensure proper sound reproduction,
correct loudspeaker polarity is necessary.
Check “+” and “−” polarity at both the
amplifiers and the IS Series speakers.
5. Make sure loudspeaker lines are not shorted
before turning the amplifier on.
6. The entire audio system must comply with
the current local standards and regulations
regarding electrical systems.
7. Ashly recommends this product only
be permanently installed by licensed,
professional installers (or specialized firms)
who can ensure a correct installation and
certified by a local inspector.
8. Do not install near any heat sources such
as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that
produce heat.
9. Use only with mounts or brackets specified
by Ashly Audio.
10. Check the suitability of the support surface
to which the product is anchored (wall,
ceiling, structure, etc.) and the attachment
components (wall plugs, screws, brackets
etc.) to confirm that they are in compliance
with requirements set forth by local building,
safety and electrical codes.
11. Make sure all connections have been made
correctly and the loudspeaker input voltage
is suitable for the amplifier output.
12. Protect loudspeaker lines from damage.
Make sure they are positioned in a way that
they cannot be stepped on or crushed by
objects.
13. Make sure that no objects or liquids can get
into this product, as this may cause a short
circuit.
14. Place the SP 12.1P subwoofer on a flat, rigid
and anti-skid surface.
Pole, Tripod Mount, Joining Plate
15. Please use Ashly IS-TR7B tripod mount for
IS 2.8P and IS 3.8P speakers. If mounting
the speakers on top of the SP12.1P
subwoofer, use only IS-PM6B adjustable
speaker poles.
16. When pole or tripod mounting IS column
speakers, make certain units are placed in a
safe and secure area which is free from foot
traffic or other activities which could cause
accidental tripping or stand collapse.
17. Open the mount’s three “legs” as wide as
possible to ensure its stability.
18. Tighten the height-adjustment bolt firmly.
19. Insert the safety pins on both the fixed and
extendable parts of the tripod or pole.
20. Make sure the the Ashly IS-JP2 accessory
joining plate used to connect to IS speakers
is securely attached.
21. When using two IS speakers joined by an IS-
JP2 vertical mounting plate, pay particular
attention to tripod placement. Confirm
that the tripod mounts’ three legs are fully
extended. Remember that the center
of gravity is higher than with a single IS
speaker.
Operation
22. IS column line arrays can deliver high sound
pressure that can surpass 90 dB. Exposure
to high sound levels can cause permanent
hearing loss. Monitor and control the volume
at all times.
23. If amplifiers or other connected equipped
displays “clipping”, “peak”, or other overload
conditions, adjust to assure these are
operating below that threshold to prevent a
distorted signal, which may cause damage
to the speakers.
24. To avoid clipping, always use a clip limiter
if available. Always observe specified high
pass filtering recommendations; failure to
do so may result in damage to drivers.
25. Contact your authorized service center
or qualified personnel should any of the
following occur:
■ The loudspeaker does not function
normally
■ The cable has been damaged
■ Objects or liquids have gotten into the unit
■ The loudspeaker has been damaged due to
heavy impacts
26. Clean only with a dry cloth. Do not use
solvents, alcohol, benzene, or other volatile
substances for cleaning the external parts of
this product.
2 7. Don’t unplug signal cables when the amp
connected to your IS Series speakers is still
on.
28. Don’t remove the metal grille of the speaker,
which can cause damage to the speaker
cones.
29. Depending on the impedance switch setting
on the back of the IS speakers (8/32 ohms),
make sure to limit the number of connected
speakers to match the amplifier’s minimum
safe operating impedance. Please refer to
the Ashly amplifiers operations manual for
the correct settings and speaker count.

Thank you for choosing Ashly IS Series line
array column speakers (and hopefully our
matching subwoofer). We know that there are
many choices on the market today; so we have
worked hard to create column speakers that set
themselves apart from the rest.
Elevate or wall-mount a pair of IS 3.8P or IS
2.8P speakers on stands, add one or more
SP 12.1P subwoofers and you have a highfidelity, high-output system that’s perfect for
reception halls, small churches, mobile discos,
bars, coffee shops, and many other applications.
Before installation, check for any possible
shipping damage. Also, please read all of the
Safety and Operation Precautions on the
previous page.

In 8 Ω mode, IS columns are ideal
for typical low-Z and live performance
applications.
However, switching IS columns to 32 Ω lets
one Ashly 4-channel amplifier drive up to 32
individual IS 2.8P or IS 3.8P speakers!
