It approximates operating with music or voice with very heavy clipping and a very compressed dynamic range.

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.ġ/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 light clipping and represents the amplifier's typical 'clean' maximum level, without audible clipping. How is the power consumption of amplifiers tested & indicated?Īs 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.Ĭurrent draw at idle or with very low signal levelĪmplifiers are tested using pink noise signals to simulate real-world speech and music signals.The steel 19' housing has a height of 2 HE. The input connection is made with balanced XLR connectors, and there’s a signal output for linking with other amplifiers. 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. Another present feature is the 24 V DC connection for powering the amplifier with emergency power when the main power is shut down. The protection circuit detects DC malfunction, short circuit, overheating, overload and limits the signal when necessary. 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. This creates great simplicity in use and installation. It is designed as a no-nonsense amplifier with only the necessary controls and connections.

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.
