Getting The Best From Your HPI12S
Connections
Two NL-4 connectors are mounted in a
recessed panel on the rear surface of the
box. This allows the speaker box to be set flat
against a wall without physical interference to
the speaker connector.
• The connector input is wired pin 1+ and
pin 1-.
• Pin 2 is not connected.
Take care when inserting the Speakon
connector twisting the connector until it
locks into place. Reverse the procedure to
4
disconnect.
Band-pass frequency range for
better results
Reducing low frequency output below 40 Hz will help
protect the 12" woofer in higher power applications.
Better sonic results will result if the HPI12S is
operating at a frequency range no lower than 40Hz.

Amplification
The performance of any loudspeaker depends
on the amplifier delivering an adequate
supply of clean power.
Please ensure a suitable amplifier is selected
for use in conjunction with the HPI12S and
accompanying speaker system.
Power in the Right Hands Can Save
Your Speakers
If the loudspeakers are used for a
professional application with competent
operators, the power principle is as follows:
When the loudspeaker is needed to achieve
maximum output levels, the amplifier
should be able to sustain a peak of twice
the wattage listed in the loudspeaker
specifications. A quality amplifier will provide
a clean peak voltage capability of 6 dB above
the maximum RMS power of the amplifier.
To avoid "clipping" or distorted output
from a lesser quality amplifier, select an
amplifier with double the RMS power rating
of the loudspeaker. The thermal limits of the
speaker are unlikely to be exceeded with an
undistorted signal.
