Manufacture Test Rating
- This is the thermal limit using pink noise to define the continuous power rating.
- Standards include AES2-1984 (r2003), EIA-426-B (2001), IEC 60268-5 and AES2-2012
- Most vendor will label this RMS and is totally incorrect.
- Will see defined as Pc, Continuous, RMS, IEC 60268-5, EIA-426-B. IEC Continuous or AES Continuous rating.
- This is the thermal limit using random frequencies of music reproduction
- This is defined as 2 x Pc, Continuous or RMS Power
- Will see this defined as Pe, PMax, Peak, Program, Music or System Power
- Caution! Some vendors will label this as peak power.
- If Peak defined as 2 x RMS then this is Max Thermal Limits not Peak
- Thermal capacity is related to coil temperature, adhesives and insulation melting point.
- Pm or PLim or Peak Power is the mechanical limitation
- An excursions greater than the Xmax parameter can damage the component.
- This is defined by 2 x Pe, Pmax, Program, Music or System Power
- Can be defined by 4 x Pc, Continuous or RMS Power
