DIGI-SYS ARAD-6D is a 1U rack-mount unit which produces an AES/EBU and Analogue audio output. Comprehensive input selection between balanced XLR or unbalanced BNC analog stereo input or up to 4 balanced AES/EBU Digital inputs or up to 2 SPDIF 75 ohms input signals. With provision for so many inputs the unit has two modes of operation, Auto mode and manual mode. In auto mode unit intelligently selects digital input no 1 on top priority and then in sequence, with decreasing priority Digital input 2,3,4 SPDIF digital 1,2 & then Analog balanced and analog unbalanced. Output is always available in digital as well as analog formats. There are isolated 2 digital outputs on XLR connectors and 2 Digital SPDIF outputs on BNC connectors. There is only one pair of analog output on XLR connectors. There is provision of head phone output on front panel with volume control, for selected output.The analogue inputs have left and right front panel analog level controls using pre-set potentiometer and additional digital control of ±20dB, through interactive control in 0.5 dB steps. The Interactive controls provide superb flexibility in optimizing signal chain. This unit can also work as AD converter and DA converter. Outputs are always available in Analog and digital Balanced form. The digital signal bit depth can be 16 or 24 bits. The large dynamic range can be optimized by microcontroller with full scale resolution. There is a failsafe bye pass relay for the main outputs.
DIGI-SYS ARAD-8 support digital input with the Sample Frequency range from 16 to 192 KHz. The unit as excellent audio performance and has analytical capabilities to decode errors in the incoming Digital signals. The unit has a LCD display which can display all incoming signal critical parameters such as sample rate, bit depth, professional/consumer format etc. etc. Outputs are always available in both Analogue and Digital form through head phone, Balanced XLR and unbalanced BNC.
DIGI-SYS ARAD-8 has excellent overall frequency response and very low distortion, which has been achieved by selectively mixing integrated circuits and discrete devices. Extremely low noise levels and phase matching exceeds all expectations. Digital input transformer with matched input receiver allows perfect recovery from week digital signals down to 100 mV.
Unique user interface through a graphical LCD and navigation controls provide unlimited configurations and fine level controls. The LCD display also acts as a bar graph display for the active input channel. The unit is housed in a 19” rack mount chassis with power connections as per IEC recommendation.
