Audio
Frequency range:The lowest and the hightest frequencies that can be inputted/produced.
100 - 24000 Hz
RMS rated power:RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplfiers and loudspeakers.
240 W
Signal-to-Noise Ratio (SNR):This is the ratio of signal intensity to noise intensity.
84 dB
Total Harmonic Distortion (THD):Total harmonic distortion is a measure of non-linear harmonic\n\ndistortion and is given in %. Non-linear harmonic distortions are\n\nsignals which were not present in the original before the signal was\n\nconverted by the headphones. These unwanted signals are caused by the\n\ndiaphragm, whose movements do not precisely move in time with the\n\nelectric signals that cause it to move. Unfortunately, this is a\n\nfeature of all electroacoustic transducers. Although it cannot be\n\ncompletely eliminated, suitable steps can be taken to minimise it.\n\nHowever, the user is not interested in why this distortion takes place\n\nbut in how great the level of distortion must be for it to become\n\nperceptible. According to the findings of several research projects, a\n\ntotal harmonic distortion of 1% in the frequency range of 100 to 2000\n\nHz is imperceptible. Below 100 Hz, the perceptibility threshold lies\n\nat 10%.

Amplifier class:An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. Power amplifier circuits (output stages) are classified as A, B, A/B and C for analog designs, and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device is passing current.
D
Peak power per channel:The maximum power (usually measued in watts) that can be transmitted through a channel.
40 W
Audio output channels:An audio output channel is an electric circuit which acts as a path for a signal produced by a device. A device may have several audio output channels.
