This manual covers the operation, settings, and maintenance of the d&b D20 four-channel Class D amplifier for mobile applications.
The d&b D20 is a new generation four-channel Class D amplifier designed for mobile applications when used with compatible d&b loudspeakers. It features Digital Signal Processing (DSP) technology, including user-defined settings, equalizers, and delay functions to optimize speaker performance.
The device includes a color TFT touch screen and front-panel rotary encoders for data input. The output mode can be configured like two dual-channel amplifiers or in mixed TOP/SUB modes. Key features include LoadMatch for cable compensation up to 70m and support for various input configurations including analog and AES3. This manual is written in Chinese.
