Daad 2 | DIGI-SYS

General Detail:

DIGI-SYS DAAD-2 is a Digital To Analogue converter 1U rack mount which Produce an stereo Analog output from a blanced xlr or unbalanced BNC Digital Inputs.

The Acceptable Sampling frequency range from 16 to 192 KHz with automatic selection . This Unit has excellent signal to noise ratio and has diagnostics capability to detect coding errers in the incoming digital signals. The Intractive controls provide superb flexibility in selecting balanced or unbalanced signals inputs. Analog outputs are always available in balanced and unbalanced both format . The large dynamic range is optimized by micro controller based full scale resolutiuon.

DIGI-SYS DAAD-2 has excellent overall frequency responce and very low distortion, which has been achieved by selectivily mixing integrated circuit and discrete devices. Design Excellence of Digital input stage , also allow Perfect recovery from week Digital Signal in the ranfe of 100Mv. There are individuals gain control for anlaog output to give ±5db level adjustment.

Unique user interface through a graphical LCD and navigation controls provide unlimited configuration and fine level controls. The LCD Display in a conjunction with built in errer analysis capability provide all critical errers in addition to parameter display . The Unit is housed in a 19 rack mount chassisn with power connection as per IEC recommendation.
