Flexible Amplification for your Next Commercial Install 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 (4Ω/8Ω). The amplifier is split so that two channels handle the lo-impedance speakers, while two channels take care of the 70V/100V speaker runs. Feature Packed 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, plus shorter runs to lo-impedance speakers.

so far so good
Haven't used it much but it sounds nice. Build quality appears to be very good...they used thicker chassis steel than they had to. I was curious to do a bit of poking around inside...this is a class D design based on the Infineon RS2092, in case you are curious.
