Denon DN-508A 8 Zone Amplifier

The Denon Professional DN-508A is an 8-channel zone amplifier perfect for commercial applications such as background music, paging, multi-zone entertainment, etc. It features eight channels of efficient, cool-running Class D amplification, each rated at 55 watts with less than 0.5% THD. Eurobloc connections ensure fast, reliable hook up—critical to your commercial/contractor business. There are individual volume adjustments and signal/peak indicators for every channel, giving you complete control of the system.

For unsurpassed versatility, the DN-508A can be used with 70/100V systems and it also has low-impedance (4 ohm) drive capability. There is no system configuration it can’t handle!

With a signal-to-noise ratio in excess of 90dB at rated power, a dynamic range of 95dB and channel separation of 60dB, the DN-508A is uniquely capable of providing clean, reliable power to multiple speakers in a demanding commercial application. It’s a perfect system companion to the DN-508MX Zone Mixer.
