Subwoofers with high level inputprices on 54 models
High level (terminals)— standard input used in acoustics to connect a signal from a power amplifier. A pair of terminals is responsible for each audio channel. It can be used both to connect a subwoofer to its own “bass” amplifier (or a special input), and to receive an overall audio signal with processing by the built-in crossover and transmitting the corresponding frequencies to external speakers. In the first case, the high-level input consists of one pair of terminals, in the second there are usually two such pairs, based on a stereo signal.
