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 high-
fidelity, 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.
Note that this Guide also covers IS-TWM Tilt
Wall Mount Bracket, IS-JP Joining Bracket, and
IS-FWM Flush Wall Mount Bracket.
Back Panel Connections
IS Series columns are designed for both
permanent and mobile applications. Both
models have Neutrik® connections. The IS
3.8P adds Neutric SpeakOn connectors; the IS

more than one jack (any type on the speaker) at
the same time.
