Alpha Control 100
4 x 3000W Intelligent Class D DSP Amplifier
Product at a Glance
The British Acoustics Alpha Control 100 is a 4 x 3000W Class D DSP amplifier built for high-demand audio systems requiring precise control and reliable power. Featuring onboard 96kHz DSP with IIR/FIR filters, EQ, delay, and limiters, it enables full tonal and timing alignment via front panel or remote network access. With a 114 dB dynamic range and 96kHz ADC/DAC engine, it ensures pristine signal fidelity. Connectivity includes Dante, AES, USB-B, and XLR, with advanced metering and LED diagnostics. Housed in a rugged 3U chassis with 4 analog and 4 Dante inputs, it’s ideal for stadiums, touring, and installations.
CRAFTSMANSHIP
Painstakingly Perfect Production
Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
