Denon Professional DN-474A, 2×2-Channel Dual-Impedance Amplifier 70V/100V & 4Ω/8Ω

The Denon Professional DN-474A is a 2×2-Channel Dual-Impedance Amplifier. This Denon Professional DN-474A is built and designed for contractor/install market applications which specify installed speaker systems requiring 70V/100V inputs and has the added flexibility of handlng lo-impedance loads (4Ω/8Ω). The Denon Professional DN-474A amplifier is split so that two channels handle the lo-impedance speakers, while two channels take care of the 70V/100V speaker runs. The Denon Professional DN-474A is very versatile, one rack space amplifier that has built-in short circuit protection and LED indicators for signal present, clipping status and thermal interruption on the front panel. The Denon Professional DN-474A is built and 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.
