Technology / Home Audio / Input Voltage: The power voltage provided to an amplifier. While most cars can be expect to reliably produce 12 volts, amplifiers are sometimes measured at higher voltages; up to 15 volts. In this way, higher power can be developed, albeit at the expense of longevity. It is a practice that allows higher power figures to be claimed.
Entertainment / Photography / Voltage Stabilizer: Is a transformer used to produce a steady output voltage despite fluctuations of input voltage. MORE
Science / Biology / Sensory Input: Stimuli that the nervous system receives from the external or internal environment; includes pressure, taste, sound, light, and blood pH. MORE
