Connections
Two Neutric Speakon model 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
disconnect.
Getting The Best From Your HPI111
Suitable Amplification
The HPI111 is an 8 ohm enclosure and can
be connected in multiple parallel connections
to an amplifier channel that can operate
at speaker impedances of 4 ohms. The
HPI111 is a mid power level high efficiency
system, so ultra high power is not necessary
to obtain high sound pressure levels. The
recommended power range per amplifier
channel is 450-500 watts RMS into an 8Ω load.
The HPI111 is ideal for use with the Quest QA
2004/3004 models.
Setting the QA amplifier’s high pass filter
at 35Hz is recommended for full range
applications. If you are intending to add
sub bass speakers or use for mainly vocal
reproduction, the high pass filter can be set
to 80Hz.

Reducing low frequency output will make more
amplifier power available for clean vocal reproduction
for full range sound, set the high pass filter to 35Hz
