ISP Technologies HDL 2208 User Manual
IMPORTANT SAFTEY INSTRUCTIONS!
Please read this very carefully before operating this unit
Read ALL instructions carefully before using this unit.
Do not operate this unit near water, in the rain or where there is moisture.
If this warning is ignored a serious electrical shock or death may occur.
Do not attempt to service this unit. No user serviceable parts inside. Refer
servicing to qualified, ISP approved service personnel.
Never remove or defeat the ground connection on the power cord of this
unit.
Care should be taken to avoid spilling any foreign objects or liquid into this
unit.
This active speaker system has a three-channel internal power amplifier
with a heatsink and a fan located inside the speaker for cooling. Air is
drawn in the front grille and hot air is exhausted out the rear of the cabinet.
Care should be taken to avoid placing this active speaker in a location
where the rear exhaust ports are obstructed and does not allow proper
cooling of the internal amplifiers. Avoid placing this system close to other
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 midrange 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 pinpoints 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.
