General Detail:-

DIGI-SYS DAAD-1 is 24 bit AD converter in 1U rack-mount chassis, which produces an AES/EBU or S/PDIF digital audio output from a balanced XLR or unbalanced BNC input. The analogue inputs have left and right front panel fine analog level controls using conductive plastic  potentiometer and additional digital control from  -20dBu to +20dBu through interactive controls. The Interactive controls provide superb flexibility in selecting balanced or unbalances signal inputs. Out puts are always available in balanced and unbalanced both formats. The output bit depth can be selected from 16 or 24 bits. The large dynamic range is optimized by microcontroller with full scale resolution.

DIGI-SYS DAAD-1 has excellent overall frequency response and very low distortion, which has been achieved by selectively mixing integrated circuits and discrete devices. The unit is capable of generating crystal accurate sample rates from 44.1, 48, 88.2 and 96 KHz.

Unique user interface through a graphical LCD and navigation controls provide unlimited configurations and fine level controls. The LCD display serves dual purpose of assisting configurations and then showing Bar graph of the signal in real time. Bar graph display is calibrated in dB with fast peak reading response. The unit is housed in a 19” rack mount chassis with power connections as per IEC recommendation.input channel.
