ISP Technologies Trimax - Manual (Page 9)

SYSTEM DIAGRAM DESCRIPTION
The ISP TRIMAX Series has balanced XLR and inputs and outputs configured to AES standards
(Audio Engineering Society). These connections are connected in a loop through configuration
from the inputs to the full range outputs and will accept a balanced line-level input. The standard
phase configuration is that pin 2 is (+), pin 3 is (-), and pin 1 is shielded ground on the XLR.
THERMAL CONDITIONS
The ISP Trimax 15 System is capable of producing upwards of 700 watts RMS when driving one
top box and 800 watts when driving two top boxes off the same sub cabinet. The TRIMAX 18
system is capable of producing over 1000 watts when driving two TRIMAX 10 top boxes. 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 onto a heatsink that is exposed on the rear of the cabinet. Airflow is forced through the
fins via the air pressure from the speaker. It is recommended that the fins have at least 6 inches
of clearance from any obstruction to allow proper ventilation to occur.
In addition, the amplifiers are thermally protected internally via a thermal switch that will
attenuate the signal 40db when the temperature exceeds a certain point. When the temperature
drops below a certain point, full signal will be restored. Tests have shown under extreme
conditions that cycling will occur. (40 sec. ON, 20 sec. OFF) Under extreme conditions, such as
when ambient temperatures are too high (hot rooms, extreme outdoor temperatures) it is
recommended to use a fan on the fins to reduce the cycling affects.
