Caution: Exposure to extremely high noise levels can
cause permanent hearing loss.
The HIGH DEFINITION LINE 2208 system is capable of producing in excess of 134db SPL
at 1 meter. Continued exposure to noise levels in excess of 90db may cause permanent
hearing loss. Below is a chart of the OSHA (Occupational Safety & Health Administration)
regulations for Occupational Noise Exposure. Please note: OSHA requires hearing
protection for any work environment when the sound levels exceed those shown in Table
G-16 when measured on the A scale of a standard sound level meter at slow response.
INTRODUCTION
Thank you for purchasing ISP Technologies HIGH DEFINITION LINE 2208 active speaker
system. The HIGH DEFINITION LINE 2208 is a high output two-way active speaker
system designed to deliver HI-FI sound quality for high SPL sound reinforcement
applications. ISP Technologies HDL 2208 is a high performance, powered, small-format
line array cabinet providing high fidelity performance and smooth, accurate response.
The HDL 2208 provides a 2-way line array design with little compromise in terms of its mid-
range performance. This is, in part, due to a new high performance non-metallic
compression driver on a multiple-aperture waveguide and dual 8-inch neo woofers. The
result is a new level of performance in a small-format line array system. The HDL 2208 is
a 10-degree vertical by 100-degree horizontal box with user adjustable pin-
points for various splay angles from 1 to 10 degrees in 1 degree increments.
The internal amplifiers are based on ISP Technologies patent pending D-CAT (Dynamic
Current Amplifier Technology) amplifier technology. The D-CAT technology is capable of
delivering extremely high output current providing an improvement in transient response,
output current and a noticeable improvement in PUNCH. The D-CAT amplifier technology
utilizes a high performance power amplifier driver that reduces parts count and greatly
improves reliability. The D-CAT amplifiers provide improved reliability by including short
circuit and over temperature protection.
The HIGH DEFINITION LINE 2208 cabinet is made of high quality 13 ply Baltic birch
plywood built with smooth sides, the boxes provide a very clean look, without any
protruding rigging or pins, and are coated with a durable polyurethane finish.

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 annually. 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.

THERMAL CONDITIONS
The ISP HIGH DEFINITION LINE 2208 Series is capable of producing in excess of 850 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 forced through a port 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 certain temperature. When
the temperature drops below a certain point, full signal will be restored. 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
transformers. If one power transformer temperature reaches a critical point the 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 2208 is continually pushed into
heavy distortion.
