Auto Sleep
Use this recessed button to switch energy-saving Auto Sleep mode on and
off. Your speaker leaves the factory with the Auto Sleep button pressed to
enable this mode. This function puts the electronic components to sleep
when four and a half hours pass without the speaker registering an audio
signal, data sent to the Ethercon ports, or an adjustment of a button or
knob. The only way to wake it up is by switching the Power button off and
on again or patching an analog audio signal into the Input.
Heads up: You cannot wake up the speaker via the Ethercon ports.
There is but one way to deactivate the Auto Sleep function – by
'unpressing' the button to set it to the up position.
3 An Overview of the Various LINEAR 9
Models
The LINEAR 9 series consists of the LINEAR 9 210 LTA, LINEAR 9 110 XA
and LINEAR 9 112 XA mid/high units and the two LINEAR 9 118 Sub A and
LINEAR 9 118 Sub BA subwoofers.The housings of the multifunctional
LINEAR 9 110 XA and LINEAR 9 112 XA models are angled 30° so you can
also set them sideways for use monitors. TheLINEAR 9 210 LTA cabinet is
shaped to enable you to quickly and easily set up clusters.

All mid/high untis are loaded with rotatable horns. The directivity of each
cabinet's horn is optimized for its primary purpose – that is, the most
frequently used application. You need tools to rotate the horns, so they are
not conducive to frequent adjustment. The idea is to optimize the throw
pattern for the cabinet's primary application.
• The LINEAR 9 210 LTA MCT horn's horizontal directivity is 60° for standa-
lone applications. If you deploy the LINEAR 9 210 LTA in a cluster, be sure
to rotate the horn so it has a horizontal directivity of 25°.
• The LINEAR 9 110 XA cab sports a 10" woofer and a horn with a wide
80°x60° throw pattern to provide uniform near-field coverage.
LINEAR 9 112 XA features a 12" woofer and a horn with a medium 70°x50°
throw pattern.
Tip: You do not have to rotate the horn when setting the XA cabs on its
side for use as a stage monitor. In fact, the upright speaker's narrower
vertical throw pattern works great in the horizontal position. Its tightly
focused directivity minimizes overlap with adjacent monitors and
reduces the risk of feedback risk because you can aim the speaker more
accurately.
4 Setting Up Speakers
4.1 The mid/high units
LINEAR 9 mid/high units may be stacked on subwoofers, mounted on
speaker stands or poles, installed with wall brackets, or flown with the
proper rigging hardware. All Mid/High models have a DuoTilt 3°/7° flange.

-3°
The all Mid/High units are equipped with the HK Audio DuoTilt 3°/7°,
a special type of pole mount for 35-mm speaker stands and poles that
provides tilt angles of -3° and -7°.
General Info about Setting Up with Speaker Stands
Heads-up: Always make sure the speaker stand is on solid footing and
be sure to observe the manufacturer's instructions as to its maximum
load-bearing capacity.
Caution!
• Use only speaker stands that are stable enough to prevent accidental
tipping. Ensure the speaker stand is designed to handle the cabinet's
weight. Adjustable stands' highest setting must be limited to prevent the
combination of speaker stand and speaker from tipping. This applies when
setting the stand on a flat, horizontal surface.
• When setting up on an uneven or sloping surface, make sure the speaker
stand's base is secured to prevent accidental tipping, either by attaching
suitable weights to the base or taking other measures to secure the
stand.
• The use of any other fixtures or fittings can result in instability that may
result in injury.
• Setting Up with the Tilt Unit
HK Audio offers the Tilt Unit as an optional accessory to secure speakers
stacked on subwoofers. It screws into the M20 mount on the LINEAR 9
118 Sub A/LINEAR 9 118 Sub BA like a speaker pole to prevent the top units
from moving. The two -3° and -7° tilt positions of the DuoTilt on the Mid/
High units can also serve to secure the stacked speaker.
-0° -3° -7°
Heads up! When you stack speakers without using the Tilt Unit to fix
them in place, be sure to secure the mid/high units – for example, with a
lashing strap to hold them in place.
