REAR PANEL DESCRIPTION 1. POWER SWITCH-This switch provides power to the internal power amplifiers. 2. POWER INLET MODULE-This module provides a connection for the power cord. 3. HIGH FREQUENCY INPUT -This jack provides a balanced input for the high frequency input from an external processor / crossover. 4. LOW – MID FREQUENCY INPUT -This female XLR connector provides a balanced input for the Mid Frequency, line level signal from an external processor / crossover. 5.
THERMAL CONDITIONS The ISP REFERENCE LINE 4215 Series is capable of producing in excess of 2000 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.
