Alesis ProLinear 820-DSP (2001)
The Alesis ProLinear 820-DSP, often just called the 820-DSP in catalogs, is a bi-amplified, two-way active studio monitor with onboard digital signal processing. It was introduced at the Winter NAMM show in January 2001 (EQ, February 2001, p.20). The idea was to give engineers room correction and voicing flexibility without outboard gear.
The monitor pairs an 8-inch Kevlar woofer with a 1-inch silk-dome tweeter. Each has its own amplifier: 80 watts for the low end, 40 watts for the highs (Mix, September 2003, p.96). A front-panel LCD and DSP section holds a multi-band EQ and crossover adjustments. At first glance the unit looks like a conventional two-way active monitor, but the digital controls offer presets like the "BBC Dip" - a gentle cut between 1 and 3 kHz that many engineers found pleasing (Mix, May 2004, p.128). Two front-firing ports flank the woofer.
Pricing landed at $799 (Mix, July 2004, p.112). Documentation outside magazine coverage is thin. No factory service manual or detailed sales brochure appears to have survived in common archives.
