Information amplifiers
Informational
— these models are similar to power amplifiers, however, after amplification, the signal goes to the built-in transformer, and only after that to a special acoustic system (information). Thus, a public address system is created, in which one amplifier channel is able to support the operation of several acoustic systems at the same time, without losing power. Some models of such amplifiers have a built-in player with a card reader, a USB port, and an FM radio. It should be noted that information amplifiers are not distinguished by high sound quality.| informational | clear | Save List |
