DIGI-SYS DAAD-3 is a combined 24 bit AD & DA converter in a 1U rack-mount, which produces an AES/EBU or S/PDIF digital audio output from a balanced XLR or unbalanced BNC analog input. It simultaneously produces a stereo balanced XLR or unbalanced BNC output from an incoming AES/EBU or S/PDIF digital input signal.
The analogue inputs have individual 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 and other parameters. Out puts are always available in balanced and unbalanced both formats. The output bit depth can be selected from 16 or 24 bits. Sample rate can be selected from 44.1 to 96 KHz as specified.
DIGI-SYS DAAD-3 has the best Digital to Analogue converter. The Sampling Frequency range from 16 to 192 KHz with automatic selection. Bit depth from 16 to 24 bits is also selected automatically. This unit has excellent signal to noise ratio with negligible distortion and excellent phase matching. Inbuilt diagnostics provide all coding errors in the incoming Digital signals.
DIGI-SYS DAAD-3 has excellent overall frequency response and very low distortion, with negligible phase errors and excellent signal level matching. Extremely low noise input stage for digital input allow perfect recovery from week digital signals in the range of 100 mV. There is an individual gain control to give ±10db level adjustment.Unique user interface through a graphical LCD and navigation controls provide unlimited configurations and fine level controls. The LCD display in conjunction with built in error analysis provide all critical parameter display. The LCD also acts as a Quad level bar graph display with fine resolution. The unit is housed in a 19” rack mount chassis with power connections as per IEC recommendation.
