Type:Characteristics of the device.
Home audio mini system
Ergonomics
Equalizer:Device that attempts to reverse the distortion incurred by a signal transmitted through a channel.
Multimedia
Frequency range:The lowest and the hightest frequencies that can be inputted/produced.
100 - 20000 Hz
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%.
20%
Signal-to-Noise Ratio (SNR):This is the ratio of signal intensity to noise intensity.
75 dB
Impedance:The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.
4 O
RMS rated power:RMS (Root mean square) is a measure of the continuous power required by a device, in particular audio amplfiers and loudspeakers.
230 W
Number of speakers:The quantity of speakers included in/with the product.

Network
Bluetooth:Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Ports & interfaces
USB port:Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
