WARNING
When the Unit is in Use
• Turn down the amplifier before switching
on the amplifier. If there is no sound,
check the speaker connections. Speakon
connectors must be locked in place.
• Should any of the following irregularities
be found during use, immediately switch
off the amplifier power, disconnect the
power supply plug from the AC outlet and
contact your nearest Quest dealer:
• If you detect smoke or a strange smell
coming from the unit,
• If the unit falls and the unit case is
damaged,
• If it is malfunctioning (no HF or low
frequency output).
Make no further attempt to operate the unit if
it is found to be in any of the above conditions
as this may cause fire or electric shock.
When Installing the Unit
• Do not expose the unit to rain or an
environment where it may be exposed to
water or other liquids, as doing so may
result in damage to the bass driver or
corrosion of the steel protective grill.
• Do not cut, kink, otherwise damage
nor modify the speaker cable. Also use
speaker cable of at least 1.5mm core
diameter. In addition, avoid locating the
speaker cables close to heaters, high
traffic areas or locations where the cables
can be damaged.
• Avoid installing or mounting speaker
boxes in unstable locations and when
flying, use the hardware designed for the
speaker box and fix securely to a solid
wall. Failing to do so may result in the
unit falling, causing personal injury and/or
property damage.
• Be sure to ground to the safety ground
(earth) terminal to avoid electric shock.
Never ground to a gas pipe as a
catastrophic disaster may result.
• Never hang a speaker box from only
one rigging point. Use multiple points
and attach a safety line to a point strong
enough to take the weight of the speaker
box.
General Description
The HPI 8i is a full frequency range
multi-purpose 2-way passive speaker system
designed for the live sound touring and
permanent installation market.
It is suited to full range front-of house sound
for short and mid throw applications in both
stand alone applications, as part of a small
array or distributed system. Its versatility
means it can also be configured in multiple
numbers as a multi-way system with sub
bass enhancement or individually as part of
a compact portable full range system with
single sub bass enhancement. (See HPI
Series bass speaker systems).
The HPI 8i requires no special system
processor and can be installed in a vertical
or horizontal installation with the horn flare
rotated to give the appropriate HF dispersion.
Features
The HPI 8i has a number of features designed
to increase performance and versatility for a
professional sound installation environment.
A great deal of attention was paid to the
details of the design to make the HPI 8i both
sonically excellent and functionally suited
to all aspects of mobile and permanently
installed sound reinforcement.
High Powered Purpose Designed
Components
A high powered 25mm exit 1.4” diaphragm
high frequency driver matched to a Quest
designed asymmetrical horn flare delivers a
hi fidelity high frequency response with a long
throw capability.
The high efficiency 8” neodymium magnet
mid-bass transducer has been designed to
function in a relatively large volume enclosure
to maximize upper bass frequency output.
The cone geometry and driver dynamic
parametersare also engineered to give a
smooth frequency response into the vocal
range.
Good vocal and midrange response makes
the HPI-8i an exceptional performer when it
comes to vocal projection and reproduction of
acoustic instrumentation.
Functional Design
Not just stylish, but practical, an integrated
carry handle also doubles as part of the
rigging system and also serves to give the
casing more strength and rigidity.
The recessed input panel allows for protection
of the plastic Speakon connectors and also
aids a visually tidy installation.
Solid Build Construction
Built for a touring environment, the HPI 8i is
well suited to all professional applications.
The timber casing is reinforced birch ply with
a heavy gauge power-coated steel grill. Like
all Quest products, it is “built tough for a
tough world”.
WARNING
Flying the box from one insert must not be attempted!
Improper installation may result in damage, injury or death.
