A.2800 Power Amplifier

Contact our experts for a recommendation of great alternatives. Call us at 800-449-9128.
Overview
Heavy-duty professional amplifier engineered for superior sound reproduction.
With a power rating of 2,800W, the Stanton A.2800 power amplifier gives you the power you want with plenty of headroom. The A.2800 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.2800's low-frequency filters (40Hz) remove rumble and subsonic frequencies. 2 rear-mounted fans cool the A.2800: cool air flows through the front fan filters, reducing the temperature of internal components while forcing the heat out the rear vents. Connections include balanced XLR and 1/4" TRS combination inputs for each channel and LINK ports. 5-way output binding posts or 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.2800 power amp includes rack ears to mount in any standard 19" rack.
