Description The d&b D20 amplifier brings together high-efficiency power and advanced signal processing in a road-worthy 2RU chassis. Its four independent channels allow flexible routing—whether you’re driving four separate cabinets or combining for mix TOP/SUB or 2-way active modes. Each channel supports a 16-band parametric EQ (plus notch, shelving or asymmetric filtering) and delay up to 10 seconds, giving you comprehensive control over alignment and tone. The touch-enabled colour TFT screen and rotary encoder deliver intuitive operation; the front panel is also tilted upward to ease control when rack-mounted low.
