Bias D1
Two Channel Power Amplifier

The two channel Bias D1 DSP+D amplifier provides reliable premier-grade power and headroom in the smallest possible package size.

Easy set up and accessible parameters result in this highly versatile Bias D1 amplifier. The front panel LED display provides status feedback, which can alternatively be obtained by connecting the amp to a PC running Armonia Pro Audio Suite™ software.

A fully integrated, state-of-the-art DSP offers extensive system management features, including sound shaping and limiter functionality. In addition, the DSP hardware and Armonia Pro Audio Suite™ software enable compliance with IEC 60849.

Designed to work with lo-Z (from 2 Ω) and 70V/100V distributed lines, any mixed configuration of low and high impedance output loads is possible, making the Bias D1 suitable for all applications in installed sound reinforcement systems. DSP+D versions of the Bias D1 extend system performance, supported by Dante™ digital audio networking architecture and the on-board, high-end signal processing.

Significant eco-friendly, energy-saving efficiency results in low operational costs, power consumption, heat dissipation and carbon footprint.
