Multi-channel power amplifiers combine Class-D efficiency with features designed specifically to benefit commercial installation sound systems.

Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer. This power amplifiers, however, can operate in both high-impedance (70V/100V line) or low-impedance (4Ω/8Ω) modes simultaneously, eliminating the need for additional equipment, as well as streamlining the installation process. Power amplifiers also enable both 70V and 100V operation for every pair of channels by simply selecting the preferred mode using the dip switches on the rear panel. High impedance operation often requires the use of two combined channels in bridge mode, but with amplifiers, 70V or 100V mode can be assigned to every pair of channels without affecting the number of output channels.
