The PMQ series are professional 70/100V quad channel power amplifiers, providing a new standard for premium sound 100V amplification in public address applications. Their advanced features and availability in different output powers provide an enormous flexibility for numerous applications.
The PMQ240 is a four channel Class-D 70/100V power amplifier with an output power of 240 Watt for each channel. The WaveDynamics™ DSP processor combination with the 2.5” LCD display gives an unmatched user experience with intuitive functions overview for easy configuration.
Acoustics can be optimized using the filters selectable between Low / High & Band Pass and the 7-Band equalizer both with adjustable frequencies and Q-factor. Other provided functions are delay and dynamic bass boost. These settings can be custom configured using the front panel of the amplifier, whereby access can be given on two different levels (User & Administrator) using password or USB-key protection.
Configuration is made simple by the loudspeaker presets and full system configurations which can be selected from a library and uploaded with a USB flash drive. This ensures the best acoustical performance with a ‘bullet-proof’ loudspeaker protection.
A great input flexibility and source compatibility is offered by the input selection matrix and the XLR and terminal block signal connections. System integration is made easy using the RS-232 control port. Optional Dante™ interface is available for the WaveDynamics™ amplifiers. The installation of this network interface allows receiving and sending of low latency, high quality audio over a standard Ethernet network.

Answer
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.
Answer
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.
The heat dissipation list for all Audac devices is in the link below.
