Denon develops new multichannel amplifiers for commercial installations

The DN-470A and DN-474A amplifiers, especially suitable for 70/100V applications, provide four channels of 120 W, inputs and outputs in Euroblock connectors, all in one rack unit.

Available already in the Spanish market through Gaplasa Professional Division, the new DN-470A and DN-474A multichannel amplifiers of Denon are designed for use in 70/100V online commercial installations.

The DN-470A is a versatile amplifier, of a rack unit, four Class –D channels of 120W each and separate gain control for each channel; circuitry for protection against short circuits and open circuitry, in addition to front Led that indicate present signal, clipping and thermal protection status.

It is specifically designed for use with lines of many 70V/100V speakers,with long cable runs, providing great power and an adequate range of inputs and outputs in Euroblock connectors, all in one rack unit.

With optimal audio quality, DN-470A has Total Harmonic Distortion specifications (Thd) of <.1% to the rated power, a signal-to-noise ratio of >95dB and channel separation of >70Db.

For its part, DN-474A is a dual impedance amplifier of 2×2 D-Class channels, designed for fixed installation applications where 70V/100V inline speakers need to be installed, in addition to adding the flexibility to amplify low impedance loads (4Ω/8Ω).

The amplifier is divided so that two channels manage the low impedance speakers, while the other two are in charge of the 70V/100V lines. Like the previous one, integrates in a rack unit protection against short circuit and open circuit, independent gain controls and led indicators of present signal, clipping status and temperature protection on the front panel.

It is designed for the distribution of 70V/100V inline speaker systems in long cable runs, as speakers, surface and speakers, as well as for low impedance speakers with shorter cable runs.
