Russound's D-Series of amplifiers are synonymous with premium performance, reliability, and durability, forming the backbone of professional audio installations around the world. The newest generation of these high-performance amplifiers is perfectly embodied in the D1675, a 16-channel amplifier that is packed with features that enhance any audio system. The advanced digital design allows for a powerful 75W per channel, divided into 8-zones. Each zone can select from either of the two available bus inputs or use its dedicated zone input. Additionally, each zone can be bridged to provide up to 150W, perfect for outdoor speakers or in larger rooms where higher sound levels are required. A key new innovation in these amplifiers is a built-in audio filter for each zone. By adjusting a handy slide switch on the rear panel, the amplifier can be configured to provide full-range sound, or to engage a custom low-pass or high-pass filter so that the amplifier can focus its output on low frequencies to power a subwoofer, or on higher frequencies when used with architectural speakers or smaller speakers that don't reproduce as much bass. You'll be seriously impressed with the D1675 as soon as you take it out of the box, with its elegant design and robust build quality, but you'll love it the most when you connect your favorite audio sources and speakers and can tailor your entire system to its exact needs, all around the home.
