The d&b audiotechnik D20 is a four-channel amplifier with an integrated DSP platform, designed for rental environments that require reliable low to medium sound pressure level performance and flexible signal processing. It offers per-channel delay and dual 16-band equalizers with multiple filter types, a colour TFT touchscreen for quick access to settings, and a rotary encoder for precise adjustments.

Key Features

• Four channels with up to 4 x 1600 W into 4 Ω, suitable for a wide range of loudspeaker configurations.
• Comprehensive DSP, including presets for all current d&b loudspeakers except the J-Series, M2 and SL-Series, plus a linear mode for custom tuning.
• Per-channel signal delay, user-definable up to 10 s (3440 m / 11286 ft), useful for time-aligning multi-zone arrays.
• Dual 16-band equalizers with optional parametric, asymmetric, shelving and notch filters on each channel for precise tonal control.
• Intuitive control via a colour TFT touchscreen (3.5" / 320 x 240 pixel) and a rotary encoder for fine adjustments.

Use Cases

• Small to medium fixed or temporary installations where accurate DSP and multi-channel amplification are required.
• Rental events needing flexible delay and equalisation for time-alignment across stages, delay towers or distributed systems.
• Applications that benefit from factory loudspeaker presets to speed setup while retaining an option for fully custom configurations.
