Designed to work with other CEDAR products, such as DNS- and Duo-series hardware modules, the CEDAR ADA is a stereo converter, one able to handle both digital-to-analog and analog-to-digital conversion. It can convert your analog audio signal into digital recordings at sample rates and resolutions of 96 kHz / 24-bit, accepting balanced and unbalanced audio signals alike.

With XLR and RCA connections, the ADA is capable of accepting and outputting analog audio at both professional and consumer levels. Input level is adjustable over an 18 dB range, while output levels can be adjusted over a range of 6 dB. You can adjust these levels by means of DIP switches and potentiometers on the rear panel. You can also change the wordlength, selecting among 16-, 20-, and 24-bits. A psychoacoustic filter is utilized to maintain a quality signal at values below 24 bits.

On the digital side, the unit sports AES/EBU connections via XLR terminations, and S/PDIF over RCA. Digital select buttons allow you to switch between the two different types of digital connections.

The ADA sports a built-in clock for syncing with other digital devices. It 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.

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.

Related Questions and Answers

Q: 1. Can I use it to input coaxial SPDIF signal into my computer?

A: No. SPDIF is a digital audio signal, therefore would not be a signal that a computer would recognize.

Q: 2. Can this ONE device be connected to one output on an atem constellations and extract audio from 2 diff inputs?

A: No. The Blackmagic Design SDI to Audio Mini Converter SDI outputs contain mixed program audio only. However, you could loop a single input through this converter and extract that audio.

Q: 3. Can i use the xlr outputs to my Mcintosh c47 preamp even though it has a built in preamp?

A: Unfortunately not, if you use the XLR outputs, there is no way to bypass the preamps and connecting 2 preamps in series will generate feedback and low frequency rumble.

Q: 4. Can i use the xlr outputs to my McIntosh c47 preamp even though it has a built in preamp? i want to utilize my preamp even though it has a built in preamp

A: Yes. The RCA Outputs are -10 level, so this may feed to a Pre-amp.

Q: 5. What are the differences between this unit and their Pro version that costs $1999?

A: The ADI-2 Pro FS R model two balanced headphone outs, two analog combo XLR/TRS 1/4-inch inputs, optical SPDIF I/O that also understands ADAT, and coaxial SPDIF (RCA) and AES I/O (XLR) via an included breakout cable. These features make the Pro model more versatile and capable of being a high fidelity audio interface for a computer. The ADI2 DAC FS is an excellent DAC, with all of the DSP , equalization and digital to analog audio conversion quality you would expect from RME, but does not have the analog inputs or other extra features mentioned above.

Q: 6. what happen if just only audio input without video input. Could audio input Embed to SDI output without video?

A: With no SDI Video input, an output will be generated but you will not have control over the resolution and rate.

Q: 7. Can I use it to acquire SPDIF signal with my computer?

A: No. SPDIF is a digital audio signal, therefore would not be a signal that a computer would recognize. Coumputers can process analog audio in and out, OR digital audio through USB.

Q: 8. What cables do I use to get the 8 channels of digital balanced audio out to a mixer? I don't see any 1/4" Y splits that will carry the signal to a mixer.

A: You need 4 TRS to TS or XLR, insert style cables to get out of the 4 connectors on the box to 8 inputs on a mixer.

Q: 9. Can you delay the audio to sync with the video? Looking to use without a computer. Audio from Mixer and Video from PTZ Camera. I will need to sync the audio, can this be done?

A: From working with this device, there is no way of delaying the audio source at all.. You can change the setting to where the analog audio is being set to the SDI stream. Like 1-4 or 5-8, etc Hope this helps.

Q: 10. Is this the latest model with the ESS 9028 chip?

A: Yes, the RME ADI-2 DAC FS Ultra-Fidelity PCM/DSD 768 kHz DA Converter stock at B&H, at the time of this writing, includes the latest version of the ESS D/A chip.
