Denon develops new multichannel amplifiers for commercial installations

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

Now available in the Spanish market through Gaplasa Professional Division, the new DN-470A and DN-474A multichannel amplifiers from Denon are designed for use in commercial 70/100V online 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; short circuit and open circuit protection circuitry, in addition to front LEDs that indicate signal present, clipping and thermal protection status.

It is specifically designed for use with many 70V/100V speaker lines,with long cable runs, providing high power and a suitable range of inputs and outputs on Euroblock connectors, all in one rack unit.

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

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

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

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