	2192 Dual D/A & A/D Converter Who is this product for? Does it have BNC word clock input/output? Why is the 2192 better? How can I use it to get audio into my computer? What sample rates does it support? What bit depths does it support? Does it output to all digital formats simultaneously? Does it perform realtime sample rate conversion? Does it perform realtime bit-depth conversion? Is dithering available? What is the latency? How is the serial copy management system (SCMS) handled? When performing A/D, which ADAT lightpipe channels are used for output? When performing D/A, which ADAT lightpipe channels are used for input? Can it slave/sync to external word clock? Does it output word clock when used as master clock source? How can I use it for I/O with my Digidesign system? Does it support dual-wire AES/EBU and S/PDIF digital interconnect? Is the TDIF (Tascam) format supported? Can the 2192 do simultaneous A/D and D/A conversion Q: Who is this product for? A: Anybody who needs extremely high-quality analog to digital, or digital to analog, conversion. Anybody who either has a digital system that supports 192kHz sample rate, or wants to be ready to upgrade. < TOP > Q: Does it have BNC word clock input/output? A: Yes. We’ve also added a 4-BNC word clock distribution amplifier for critical clock distribution, thus eliminating the need for a separate clock source. The 2192 has an ultra-low jitter, ultra-stable internal clock that can sync to a wide range of external sources and sample rates (including the ability to convert house-sync to 96k or 192k) , and it makes a terrific master clock for a digital studio that would be worth its price for this alone. < TOP > Q: Why is the 2192 better? A: Features like sample rates up to 192k, realtime transcoding between AES/EBU, S/PDIF and ADAT, and support for single and dual wire AES modes are cool, but what really sets the 2192 apart is its fully-differential Class-A analog circuitry which provides luscious detail and clarity, while retaining the warmth and character of the original source, features typically not found in other digital units. < TOP > Q: How can I use it to get audio into my computer? A: You can connect it to any hardware that supports AES/EBU, S/PDIF, or ADAT optical "lightpipe" I/O. < TOP >

Q: What sample rates does it support?
A: The following sample rates are supported (in kHz): 44.1, 48, 88.2, 96, 176.4, and 192.

< TOP >

Q: What bit depths does it support?
A: 24 bit only.

< TOP >

Q: Does it output to all digital formats simultaneously?
A: Yes.

< TOP >

Q: Does it perform realtime sample rate conversion?
A: No.

< TOP >

Q: Does it perform realtime bit-depth conversion?
A: No.

< TOP >

Q: Is dithering available?
A: There is no dithering. Dither is best applied in the mastering stage before conversion.

< TOP >

Q: What is the latency?
A: Because we are using the highest quality A/D and D/A converters available, the total analog-input to analog-output latency is around 140 samples.

< TOP >

Q: How is the serial copy management system (SCMS) handled?
A: The SCMS bit is removed during digital to digital format transcoding.

< TOP >

Q: When performing A/D, which ADAT lightpipe channels are used for output?
A: At 48kHz, the L/R analog channels are output on lightpipe channel pair 1/2, and are copied to 3/4, 5/6, and 7/8. Similarly, at 96KHz, the lightpipe outputs 1/2 are copied to 3/4 (there are only four channels available at 96kHz). At 192kHz, all 8 ADAT channels are required for the 2 signal channels.

< TOP >

Q: When performing D/A, which ADAT lightpipe channels are used for input?
A: When ADAT is selected for input, optical channels 1 & 2 are at 48kHz, channels 1-4 at 96kHz, and all 8 channels at 192 kHz (using industry standard S-Mux interleaving on ADAT).

< TOP >

Q: Can it slave/sync to external word clock?
A: Yes. We also support sub-clock sync, which allows the use of 48kHz word sync when operating the converters at 96kHz and 192kHz.

< TOP >

Q: Does it output word clock when used as master clock source?
A: Yes. The internal master clock is an ultra-low jitter design that outperforms most stand-alone word clock generators.

< TOP >

Q: How can I use it for I/O with my Digidesign system?
A: You can connect it to any Digidesign interface that supports AES/EBU, S/PDIF, or ADAT optical I/O.

< TOP >

Q: Does it support dual-wire AES/EBU and S/PDIF digital interconnect?
A: Yes. This provides backwards compatibility for 48kHz and 96kHz digital interfaces like those found on Pro Tools | HD.

< TOP >

Q: Is the TDIF (Tascam) format supported?
A: No. You must convert TDIF to either AES/EBU, S/PDIF or ADAT lightpipe.

< TOP >

Q: Can the 2192 do simultaneous A/D and D/A conversion?
A: yes
