Each 450 Series has independent or linked volume control on each of four amplifier/pre-amplifier pairs. The 450 Series multi-zone amplifiers may be interconnected via the expansion bus, providing up to 32 zones, which vastly simplifies installation cabling.
The 450 Series, like other Vantage products, is designed to maximize control, simplify functionality, and expedite installation. The amplifiers are protected against short-term output shorts and have three progressive levels of thermal protection. Vantage products are built to the highest standards of quality and reliability.
