5 Bass Extension and Cardioid Setups
with the HK Audio LINEAR SUB 1500 A
A perfect acoustical, mechanical and visual match, the powered HK Audio
L SUB 1500 A subwoofer is the ideal complement to the E 115 Sub D. Be sure
to set the LINEAR SUB 1500 A's Phase switch to 0 degrees and the X-Over
Bass switch to 100 Hz before connecting this subwoofer. The position of
the Confi guration switch is irrelevant in this case because it only aff ects the
level of the LINEAR SUB 1500 A's Line Out Mid/High ports.
The E 115 Sub D off ers two outputs that let you add on the LINEAR SUB
1500 A, either as a bass extension or to confi gure a cardioid setup:
5.1 Operating the LINEAR SUB 1500 A as a Bass
Extension
Connect the LINEAR SUB 1500 A to the Thru ports on the E 115 SUB A for it
to receive the unprocessed signal routed into the E 115 Sub D's input. Adjust
the level using the Gain Bass knob on the LINEAR SUB 1500 A. In this case,
you can place the LINEAR SUB 1500 A beneath or beside the E 115 Sub D.

5.2 Operating the LINEAR SUB 1500 A in a Cardioid
Setup
The E 115 Sub D is equipped with a separate Cardioid Out bus. Providing
a signal tuned precisely to the LINEAR SUB 1500 A, this output lets you
confi gure a cardioid setup with a rearward-facing LINEAR SUB 1500 A
without having to make any other adjustments. However, please be sure to
set the Gain Bass knob on the LINEAR SUB 1500 A to + 6 dB by turning it
clockwise to the far right position, the Phase switch to 0 degrees, and the
X-Over switch to 100 Hz. The E 115 Sub D's DSP will take care of the rest.

Cardioid Out
Heads up: The cardioid setup requires the LINEAR SUB 1500 A to be
placed below the E 115 Sub D. A side-by-side array will not achieve the
desired eff ect! Also, be sure to always maintain a distance of at least one
meter from walls.

When is it a good idea to go with a cardioid setup?
While speakers are able to throw midrange and high frequencies in
directional patterns, low frequencies tend to radiate in all directions.
Excessive bass levels can often be a problem on and behind the stage. And
promoters are increasingly making demands to limit sound systems' low-
end reach, for example, in festival tents at urban venues. Such demands
for limiting low-range frequencies' range are best met with cardioid setups.
With its hardware appointments and fi lter sets, the E 115 Sub D provides a
fast, easy way to confi gure eff ective cardioid setups.
