Description
d&b audiotechnik D20 Four Channel Amplifier
The d&b audiotechnik D20 is a compact four-channel amplifier engineered for installation and mobile applications.
It is built on d&b's latest DSP platform, and supports all current d&b loudspeakers plus linear mode operation. Each channel delivers up to 1600W into 4Ω, with dual 16-band parametric EQs offering precise tonal shaping through parametric, asymmetric, shelving, and notch filters.
The tilted colour TFT touchscreen and rotary encoder enable intuitive, ergonomic control on the fly. With up to 10 seconds of delay per channel and LoadMatch technology that compensates for cable properties without extra conductors, the D20 maintains tonal integrity across extended cable runs. Class D amplification with active PFC ensures stable operation across global mains voltages. Flexible output connectivity, NL8 multicore, four NL4s for dual-channel mode, and dedicated outputs for Mix TOP/SUB and 2-Way Active configurations, accommodates diverse installation scenarios. Network control via Ethernet (OCA/AES70) and CAN-Bus integration with d&b R1 Remote software streamlines system management.
