Overview

With a power rating of 900W, the Stanton A.900 gives you the power you want with plenty of headroom. The A.900 offers 2-channel, parallel, or bridged mono operating modes for flexible applications. Each channel features an independent limiter to reduce distortion and an independent input level control for precise adjustments. Precise signal and clip LED indicators let you monitor performance and correct for overloading (clipping) conditions. The A.900's low-frequency filters (40Hz) remove rumble and subsonic frequencies. A single rear-mounted fan cools the A.900. Connections include balanced XLR and balanced 1/4" TRS combination input connectors for each channel and LINK ports. 5-way output binding posts and Speakon connectors enable secure operation. High-current toroidal transformer for absolute reliability. Independent DC and thermal overload protection on each channel automatically protects amplifier and speaker from damage or failure. The A.900 includes rack ears to mount in any standard 19" rack.

Best Kept Secret

By dJ Blaze

from Detroit, MI

The Stanton Power Amps are among the best kept secrets when it comes to amplifiers. I never expected this amp to be the quality piece of equipment it has turned out to be. I use two A.900s in bridged mode with two Yamaha S115Vs, and the sound is loud and crystal clear with no hint of clipping or lack of power. I plan on purchasing the A.2800 when I'm ready to add a subwoofer.
