Omschrijving
Digital Amplifier
Digital amplifier converst analog signal to short wave in which the pulse width changes in time (PWM = Pulse Width Modulation). Short waves turn FET (Field Effect Transistor) on/off and it integrates the signal and drives speakers.
Compared to analog amplifier, it has a higher efficiency, generates lesser heat and has low consumption of electricity. As it consumes less electricity, it does not require metallic plates to radiate heat, making it an environmental product.
Bass Reflex Sound System
Bass reflex unit refers to one of the speaker box systems, where this enclosed speaker box has a hole to let air in to revert a sound phase from a sound behind a speaker unit, turning it into the same sound phase as one from the front speaker. This helps in amplifying base sound - acting like a subwoofer.
