During the 1970s, the MC-2300 was an expensive piece of audio equipment, with a retail price of $1799 by the time of its discontinuation in 1980. [1] That being said, its outstanding power and sound production quality made it a valued part of many recording studios and although some people prefer the sound of tube amplifiers, the overall greater reliability and freedom from repair of the newer ...
The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...
At any instant, the power P (watts) consumed by a resistor of resistance R (ohms) is calculated as: = = = where V (volts) is the voltage across the resistor and I (amps) is the current flowing through it. Using Ohm's law, the two other forms can be derived. This power is converted into heat which must be dissipated by the resistor's package ...

Airwatt or air watt is a unit of measurement that represents the true suction power of vacuum cleaners. It is calculated by multiplying the airflow (in cubic metres per second ) by the suction pressure (in pascals ).
The LM386 is one of the most common amps used in DIY guitar preamplifiers and sustainers due to its ability to run on a single 9V battery. The EasyEDA "Tesseract" Guitar Practice Amplifier is a versatile design based on the LM386 and features distortion and full-wave rectification effects.
HF Output power: 2 Watts (PRC-127) / 3 Watts (PRC-127A) Sensitivity: 0.25 μV; Power supply: AA cells or NiCad- batteries. Specialities: Lid covers keyboard. An extra speaker/mike can be used as well as the VOX/PTT adapter used by special forces units.
The signal-to-noise and distortion ratio (SINAD) is a measure of the quality of a signal from a communications device, often defined as = + + +, where is the average power of the signal, noise and distortion components.
