LINEAR 3 1.2
• The Gain knob's default setting is the 12 o'clock position (+4 dBu / center-
notched 0 dB). This is the preferred level if you have connected a mixer to
the LINEAR 3 cabinet. If you plug a CD player or keyboard straight into the
cabinet, you may have to turn this knob to adjust the gain to match it to
the device's signal level.
Caution! Turn the Gain knob counterclockwise all the way down to the far
left when switching the input sensitivity from Line to Mic.
• If you hear distortion or clipping occurs, fi rst check the signal sources and,
if possible, reduce the output signal level there.
4 Aiming the Cabinet
4.1 DuoTilt™ 3/7
The HK Audio DuoTilt 3/7 pole mount lets you align LINEAR 3 cabinets
vertically on a speaker stand or mounting pole to prevent or reduce
troublesome ceiling refl ections. The front aperture of the HK Audio DuoTilt
provides a 7° angle, the rear aperture a 3° angle of tilt.
Rule of thumb: We recommend that you opt for the 7° angle if the audience
close by and you place cabinets at an elevated position—for example, on
stands on the stage—or if the audience is seated. This way the sound and
particularly the high frequencies are distributed more uniformly right on up
to the front face of the speakers.
–7°
If you wish to address more listeners at a greater distance from the
speakers, opt for the 3° angle on the HK Audio DuoTilt 3/7.
–3°
In both situations, you can vary the speakers' reach by adjusting their
height. They throw sound over a greater distance as their elevation
increases.

4.2 Rigging Points
Every LINEAR 3 model comes with three countersunk M8 rigging points.
They lets you fl y the speaker on steel cables or chains at inclinations from
0° up to 45°. When fl ying the cabinet, for example, from a truss, use the
rear rigging point to determine the degree of inclination.
We recommend using our secure AP-8 suspension points to rig the speaker
to the mounting hardware.
