1 Aligning Cabinets with<br />
DuoTilt<br />
The novel integrated DuoTilt pole mount allows<br />
sound energy to be utilized far more efficiently.<br />
With two angles of tilt to choose from, 3° and 7°, the<br />
enclosure can be aimed directly at the audience.<br />
The cabinet is stabilized at its center of gravity – no<br />
wobbling, unwanted tilting, or unintentional turning.<br />
Your choice of DuoTilt angle – 3° or 7° – depends<br />
on the required speaker height and the size of the<br />
room. If you set mid/high units on fully extended<br />
tripods or mounting poles, select 7° to minimize<br />
ceiling reflections.<br />
If you want to address an audience where more<br />
listeners are farther away from the speakers, use the<br />
HK Audio® DuoTilt at the 3° angle.<br />
Mono Tilt 3 (PR:O 8 A) offers one angle of tilt.<br />
2 Connecting Components and<br />
Speakers<br />
HK Audio ® speaker cords with a diameter of 2 x 2.5<br />
sq. mm are recommended for connecting cabinets,<br />
power amps or powered mixing consoles. Cords are<br />
available in the following lengths:<br />
1. LSC 3, item no.: 193283, 3 m<br />
2. LSC 7, item no.: 193263, 7 m<br />
3. LSC 15, item no.: 193323, 15 m<br />
Recommended Amplifier Power Output<br />
Connect amps rated from 600 W @ 4 W RMS to 800 W<br />
RMS @ 4 W per amp channel to power the PREMIUM<br />
PR:O cabinets. To have enough headroom available<br />
for dynamic musical signals, the power amp should<br />
deliver peak performance of at least 1,200 W @ 4 W<br />
per channel.<br />
Note:<br />
An electrical connection between the cord and input<br />
jack is not established until the Speakon connector<br />
locks into place. Twist the Speakon connector clockwise<br />
until it engages.<br />
