The d&b D20 is a 2U rack mountable four channel amplifier suited to applications requiring low to medium Sound Presure Level (SPL) capabilities and features the same Digital Signal Processing (DSP) platform as the latest generation of d&b amplifiers, containing configurations for all d&b loudspeakers except the J-Series and the M2 monitor, plus a linear mode.
The D20 provides two user-definable 16-band equalizers with parametric, notch, shelving and asymmetric filters and up to 10 seconds of delay; all of which can be applied to each of the amplifier's four channels.
A colour TFT touchscreen provides quick access to the menu structure, whilst the rotary encoder can be used for fine adjustment.
It also incorporates active Power Factor Correction, which maintains a stable output when used with weak or unstable mains supplies.
An NL8 provides all outputs on a single connector for multicores whilst dual channel mode is driven through four individual NL4 connectors.
EtherCON and RJ45 connectors enable access to the d&b Remote network through OCA/AES70 via Ethernet and through CAN-Bus respectively.
