Denon Pro DN-474A 2x2-Channel Dual-Impedance Amplifier, 2x 120W with 70/100V

The DN-474A 2x2-Channel Dual-Impedance Amplifier is designed for contractor/install market applications which specify installed speaker systems requiring 70V/100V inputs and has the added flexibility of handling lo-impedance loads (4Ohms/8Ohms). The amplifier is split so that two channels handle the lo-impedance speakers, while two channels take care of the 70V/100V speaker runs.This very versatile, one rack space amplifier has built-in short circuit protection - and LED indicators for signal present, clipping status and thermal interruption on the front panel. Engineered for the distribution of multiple 70V/100V speaker systems over long cable runs - such as in-ceiling speakers, surface-mount speakers and paging horns and also for shorter runs to lo-impedance speakers.
