Alpha Control 80

4 x 2000W Intelligent Class D DSP Amplifier

Product at a Glance

The Alpha Control 80 is a 4 x 2000W DSP amplifier engineered for high-precision, multi-channel applications that require exceptional sonic clarity, advanced DSP processing, and compact rack efficiency. Housed in a 3U chassis, this Class D amplifier integrates intelligent DSP control with 96kHz ADC/DAC conversion, a wide 114 dB dynamic range, and extensive IIR/FIR crossover and EQ functions. This provides system engineers with the tools needed to achieve optimal tonal shaping and alignment.

With AES and Dante integration, along with XLR, SpeakON, and USB-B interfaces, the Alpha Control 80 is tailored for seamless signal routing in professional touring and installation environments. It supports 4 analog and 4 Dante inputs, with fully independent DSP and output monitoring on each channel. High-efficiency power delivery, intelligent protection circuits, and intuitive front-panel navigation make it an ideal solution for fixed installations, live sound racks, and zoned audio distribution that require dependable performance and full remote configurability.

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.
