heat sources. The internal heatsink may reach high temperatures under
normal use. Make certain there is proper ventilation for the speaker when in
use.
Do not drive the HIGH DEFINITION LINE 2208 into excessive heavy
distortion for an extended period of time to avoid premature speaker failure.
Failure to follow these instructions may void the warranty.

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.

REAR PANEL CONNECTION DIAGRAM

1. Two external amplifiers are required to power each HIGH DEFINITION LINE 4210 box.
The ISP Technologies HIGH DEFINITION AMPLIFIERS are provided for ease of use
and simple connection to a five-way digital crossover box. Make sure that the digital
crossover box is configured with proper ISP Technologies approval, prior to use.
2. Make sure that all of the proper cables are available. These connections require an 8
conductor speaker cable, 4 conductor speaker cable, ¼’ phone cable and XLR cables
with male and female connection ends.
3. Connect the outputs of the crossover/processor box to the inputs of the first pair of
HIGH DEFINITION AMPLIFIERS (H.D.A. 1003-8 and H.D.A 1003-4) as shown in the
connection diagram. Connect a short jumper from the LOW 1 output to the LOW 2 input
of the second external amplifier.
4. Connect the Speaker Outputs of the amplifiers to the speakon inputs of the HIGH
DEFINITION LINE 4210 box. 8 conductor and 4 conductor speaker wire must be used
in order to achieve all necessary connections. Also connect the HF jump using a short
¼’ phone cable. This cable brings the HI channel output from the bottom external
amplifier to the speakon connector on the top external amplifier.

5. Daisy Chain the four outputs from the first pair of external amplifiers to the inputs of the
next pair of external amplifiers. Connect the speaker outputs to the next HIGH
DEFINTION LINE 4210 box.
6. Repeat this process for all line array boxes until full connection is achieved.

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.
