INTRODUCTION
Thank you for purchasing ISP Technologies HIGH DEFINITION LINE HDL3112 speaker
system. The HDL 3112 is a high output three-way active speaker system designed to
deliver HI-FI sound quality for medium and high SPL sound reinforcement applications.
The HDL 3112 is a single element line array cabinet available in two maximum vertical
coverage angles, either 8 degree or 15 degree, with adjustable splay angles. The driver
complement is one 12-inch high efficiency neodymium woofer, one 3-inch voice coil
neodymium midrange compression driver, and three 1.75-inch polyester
diaphragm neodymium high frequency compression drivers. The HDL 3112 has three
separate power amplifiers capable of producing upwards of 800 watts of RMS power, and
an internal active analog crossover. The internal amplifiers are based on ISP
Technologies patented D-CAT™ (Dynamic Current Amplifier Technology) amplifier. The
D-CAT technology is capable of delivering high output current providing an improvement
in transient response and a noticeable improvement in PUNCH. The D-CAT amplifiers
provide improved reliability by including short circuit and over temperature protection.
The built-in crossover is aligned so that a single box provides nominally flat response
from 100 Hz to 17 KHz, when a signal is input to the full-range XLR input, and the rear
panel switch is set to the Full Range position. An external high-pass filter is needed at
70 Hz or higher. This may be supplied by driving the box with the high-pass output
from an ISP powered subwoofer, or an external processor. When using multiple boxes,
an external processor or equalizer must be used to provide an array EQ function, which
rolls off the lower frequencies and boosts the high frequencies. The amount of this
spectral tilt is dependent upon the number of boxes used and the splay angles between
them. Higher splay angles create more high frequency divergence, which requires more
HF boost. For improved performance and controllability, an external processor can be
used to provide a 3-way crossover for the box, feeding each band separately via the
rear-panel ethercon connector. The rear panel switch must be set to the 'Three-way'
input position, which also disables the level control knob. Feeding signal to the box this
way allows the use of digital alignment delay on the woofer, which slightly improves the
horizontal response. ISP can supply the purchaser with recommended processor
settings for both the Full Range and 3-way uses. In the 3-way input use, there is still
significant internal high-pass filtering occurring so that accidental swapping of signal
lines at the ethercon fan-out should not damage the HF or MF drivers.
LineCalc112 Software, which is an Excel spreadsheet, is available to aid in aiming the
boxes and predicting SPL levels in a venue.
The HDL 3112 cabinet is made of high quality 13 ply Baltic birch plywood with a durable
spray on black splatter polyurea finish for long life.

Users in outside countries should consult with appropriate engineering and regulatory
authorities for specific guidelines.
Correct use of all flyware is required for secure system suspension. Careful calculations
should always be performed to ensure that all components are used within their working
load limits before the cabinet suspended. Never exceed the maximum load ratings.
Before hanging any speaker system, always inspect all components for cracks,
deformations, corrosion, missing, loose or damaged parts that could reduce strength
and safety of the cabinet. Do not suspend the cabinet until the proper corrective action
has been taken.
ATTACHMENT TO STRUCTURES
A licensed professional engineer must approve the placement and method of attachment
to the structure prior to the installation of any overhead object. The following
performance standards should be provided to the professional engineer for design
purposes; Uniform building code as applicable, Municipal Building code as applicable and
Seismic Code as applicable.
INSPECTION and MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, they require
regular inspection and routine maintenance to insure proper function ability. Any
suspended ISP Technologies loudspeaker must be inspected for fatigue at least once per
year. The inspection shall include a visual survey of all corners and load bearing
surfaces for signs of cracking, water damage, de-lamination, or any other condition that
may decrease the strength of the loudspeaker enclosure.
Flyware that is provided with or for any ISP Technologies loudspeakers must be
inspected for fatigue at least annually. The inspection shall include a visual survey of
the material for signs of corrosion, bending, or any other condition that may decrease

REAR PANEL CONNECTION DIAGRAM
The HDL 3112™ rear connection panel
provides both a single ETHERCON input
connector, which includes all 3 input signals
via a shielded CAT-5 connector and a single
XLR Full Range input. The XLR Full Range
input is processed internally to provide the
correct crossover points for the HDL3112. A
Full Range Level adjustment is provided to
adjust the level of each individual HDL3112,
note: this level control only works for the Full
Range input. For even more accurate time
alignment of the system, an external
processer can be used to provide both the
crossover points of the system and additional
system equalization. Outputs signals are
available for both ETHERCON 3-band signals if
using the ETHERCON input or XLR Full Range
output if the XLR input connector is used.
Both the ETHERCON 3-Band input and the
XLR Full Range input connectors include a
ground float circuit to help avoid ground loops
as a result of multiple cabinets connected in a
system. A 3-Band meter is provided to indicate when a
signal is present in each of the 3-Bands and when the
input signal is at the point of clipping in each band. The
input signal LED will light 21dB below the clip point and
will indicate a remaining headroom of 21dB in that
specific band. An external DSP Processor is required to
provide the correct crossover and system equalization
for the HDL 3112 system.
The diagram to the right shows the 3-WAY ETHERCON
Schematic for the input of the HDL 3112 Line Array
cabinet. The HDL 3112 requires the use of shielded
CAT-5 cable in order to provide a ground connection for
the input circuit. An ETHERCON input breakout cable is
available from ISP Technologies allowing for separate
XLR input connections for each of the 3-Band input
signals Low, Mid and High. If you make a custom input
cable you must follow the connection diagram shown to
ensure that the proper input signal is applied to the
correct band of the HDL 3112.
The rear panel of the HDL 3112 also
has the AC power connections
allowing connection to AC power
with a Neutrik PowerCon inlet
connector. Under the Power input
is a Neutrik PowerCon outlet
connector, which allows connection
to one additional cabinet. It is not
recommended to connect more than
one additional cabinet to this
PowerCon outlet to reduce the
possibility of overloading a single
AC power circuit and also to avoid
excessive current required from a
single AC PowerCon inlet. This
panel also includes a panel mount
AC protection fuse.
KNOW THE RULES OF SAFE RIGGING
The system is designed to facilitate the
suspension of the HDL 3112 by a
qualified person familiar with rigging
hardware and industry practices.
Improper installation may result in
damage, injury, or death!
The HDL 3112 can only be rigged using the
ISP Technologies HDL 3112 lightweight
ARRAY FRAME shown to the right. The HDL
3112 ARRAY FRAME can be used for both
flying applications and for ground stack
setups. When flown, only use 5/8” shackles
to attach to the steel links on the frame.
In a flown configuration the cabinet
angles are set by sliding the link
from the top cabinet down into the
slot of the rear hinge on the next
cabinet and inserting the quick
release pin in the proper hole
selection for the desired splay
angle. In a ground stack
configuration, simply select the
desired splay angle and pin the link
into the proper hole. You then
insert the additional quick release
pin into the ground stack hole in
order to obtain the desired splay
angle.
THERMAL CONDITIONS
The ISP HIGH DEFINITION LINE 3112 Series is capable of producing in excess of 800
watts at full power. This generates heat that must be dissipated in order to maintain
reliability and insure the amplifier components stay within their operating temperature
specs. To accomplish this, the amplifier is mounted on a heatsink that is internal to the
cabinet. Airflow is drawn in from the front and is forced through a port on the rear near
the internal heatsink.
In addition, the amplifiers are thermally protected internally via a thermal switch, which
will attenuate the signal 40dB if the heatsink temperature exceeds a safe operating
temperature. When the temperature drops below a critical point, full signal will be
restored. This also protects the system if the internal fan should fail. Tests have shown
under extreme conditions that cycling will occur approx. (40 sec. ON, 20 sec. OFF)
It should also be noted that a separate internal thermal breaker also protects the power
transformer. If the power transformer temperature reaches a critical point, the
transformer internal thermal breaker will open. If this condition occurs, simply reduce
the signal level of the system. This will only occur if the HIGH DEFINITION LINE 3112 is
continually pushed into excessive heavy distortion.
