The CEDAR Audio ADA is a 24-bit, 96kHz 1U rackmount AD/DA converter that produces an AES/EBU or SPDIF output from a balanced or unbalanced analogue stereo input, and a stereo balanced or unbalanced output from an incoming AES/EBU or SPDIF input. Designed to complement CEDAR's award-winning DNS-series and Duo-series hardware modules as well as CEDAR Cambridge, the ADA offers four sync modes, professional and consumer formats, emphasis on/off, user-selectable input levels of up to 27dBu, and a maximum output level of +24dBu.
 
With both professional (XLR) and consumer (phono) analogue inputs and outputs, the ADA is usable in almost all analogue and digital environments. With a dynamic range of greater than 110dB and a signal to noise ratio of better than 109dBfs, it's suitable for all but the very most demanding converter tasks.
 
For syncing with other digital devices, the ADA incorporates a built-in clock that operates in four sync modes: Master, Slave, Auto, and Auto Lock. The device offers a test mode for calibrating the unit any time after you change gain settings. The ADA fits in a studio rack, taking only 1 RU of space.
 
Synchronization Modes
Master Sync Mode
- The clock signals are generated internally by an onboard master clock at a user-selectable rate of 32, 44.1, 48, 64, 88.2, or 96 kHz.
 
Slave Sync Mode
- If a digital signal is present at the selected digital input, the ADA synchronizes to it. If no such signal is present, no output is generated.
 
Auto Sync Mode
- If a digital signal is present at the selected digital input, the ADA synchronizes to it. If no such signal is present, the ADA uses its internal master clock at the user-selected sample rate.
 
Auto-Lock Sync Mode
- This operates in the same manner as Auto Sync Mode; except in cases where no digital signal is present, the ADA uses its internal master clock running at the most recently synchronized sample rate.
