Thermal Loss Table
Table 2 provides typical thermal loss in BTU/hr. and kcal/hr. for each model as a function of load and output power level.
• 1/8 power (pink noise) represents typical program with occasional clipping. Use this rating for most applications.
• 1/3 power (pink noise) represents severe program with heavy clipping.
• Full power (sine) are continuous sine wave driven at 1% clipping.
• Thermal or overcurrent cutback limits duration of full power 2 Ohm operation.
