Denon DN-474A overview

  • 1Description

The Denon Pro DN-474A is a 2x2-channel, dual-impedance amplifier designed for contractor and retail installation markets, where the specified speaker system requires 70/100V inputs and has the added flexibility of handling low-impedance loads (4/8 Ohms). The 2x2 amplifier is split; it offers two channels of 70/100V outputs, while the additional two channels provide low-impedance outputs.

The single RU enclosure includes LED indicators for signal present, clipping status, and thermal interruption. Additionally, the amplifier offers protection for short-circuits and open-circuits. Distribute audio to multiple 70/100V speaker systems over long runs, such as in-ceiling speakers, paging horns, and surface-mount speakers, as well as shorter runs to low-impedance speakers.

  • Four-channel, Class-D amplifier
  • Two 120W with 70/100V outputs
  • Two 150/90W with 4-/8-Ohm loads
  • Euroblock inputs and outputs
  • Separate gain controls for each channel
  • Signal, clipping and thermal interruption indicators
  • Short-circuit and open-circuit protection
