The CPA36 is a professional single channel 100V power amplifier with a power of 360 Watt, especially designed for most common 100V PA systems, and perfect to be used in combination with the CPR12 pre-amplifier. It is designed as a no-nonsense amplifier with only the necessary controls and connections. This creates great simplicity in use and installation. There are several power output taps available for use in 100V, 70V and even 4 Ohm Low impedance installations and they are fitted with an advanced multipurpose protection circuit. The protection circuit detects DC malfunction, short circuit, overheating, overload and limits the signal when necessary. Another present feature is the 24 V DC connection for powering the amplifier with emergency power when the main power is shut down. At the back of the amplifier, there are trim potentiometers to set the input level, a high pass filter switch and a ground lift switch provided. The input connection is made with balanced XLR connectors, and there’s a signal output for linking with other amplifiers. The steel 19" housing has a height of 2 HE.

As the power consumption of an amplifier, strongly depends on how hard the amplifier is driven, measurements are provided for various loads: idle, 1/8 of average full power, 1/3 of average full power, and full power.
Idle
Current draw at idle or with very low signal level
1/8 Power: Pink Noise
Amplifiers are tested using pink noise signals to simulate real-world speech and music signals. It approximates operating with music or voice with light clipping and represents the amplifier's typical "clean" maximum level, without audible clipping. This 1/8 power signal provides a very good approximation of how hard an amplifier would be driven by typical real-world speech/music signals, assuming those signals were being driven as loud as possible without clipping the amplifier.
1/3 Power: Pink Noise
1/3 Power Pink Noise is similar to 1/8 Power Pink Noise, except that it is a significantly more powerful input signal. It approximates operating with music or voice with very heavy clipping and a very compressed dynamic range. This 1/3 power signal provides an approximation of how hard an amplifier would be driven by typical real-world speech/music signals, assuming those signals were being driven loud enough to clip the amplifier heavily, and produce severe, audible distortion.
Full Power
Current draw at full power is measured with a sine wave at its maximum possible level. However, it does not represent any real-world operating condition and represents the absolute extremes that an amplifier could ever experience.
Heat dissipation is the process by which electronic devices like amplifiers and processors release the heat they generate during operation to prevent overheating. This data is important because it ensures devices perform efficiently, last longer, and are safe to use. To calculate heat dissipation, you measure the device's power consumption (in watts) and use the thermal resistance (how well the device transfers heat) to determine how much heat needs to be managed. This information helps design proper cooling systems, ensuring the device remains within safe temperature limits.
