Lynx AES16-SRC

The Lynx Studio Technology AES16-SRC multi-channel interface is the ideal way to integrate digital consoles, multi-channel A/D and D/A converters, and hard disk recorders with computer-based workstations. Using exclusive SynchroLock technology, jitter is eliminated for the purest conversions possible, and the AES16 supports sample-rates up to 192kHz.
Large, on-board buffers ensure glitch-free recording and playback, aided by an extremely efficient zero-wait state DMA engine. These features provide tolerance to system latencies and significantly reduce load on the host CPU.
The AES16-SRC is a great multi-channel centerpiece of a digital studio.

Integrates digital consoles, multi-channel A/D and D/A converters, and hard disk recorders with computer-based workstations.

The Lynx AES16-SRC offers excellent AES/EBU channel capacity and routing flexibility in a single PCI card. The AES16-SRC also gives you 8 channels of onboard sample rate conversion. With support for up to 16 channels of input and output at sample rates up to 192kHz, the Lynx AES16 turns your computer into a powerful digital router or patchbay with extensive flexibility and minimal cabling. Most importantly, the AES16-SRC supports the emerging single-wire 192kHz standard and is compatible with existing dual-wire AES/EBU devices. Install up to 4 Lynx AES16-SRC cards in a single computer.

Lynx includes 2 CBL-AES1604 cables with the AES16-SRC. The 6' cables feature 110-Ohm shielded twisted cabling. Each has 26-pin, high-density male D-sub to 4 female XLR (AES inputs), 4 male XLR's (AES outputs), and 2 female BNC's (word clock I/O).


Innovations:
SynchroLock™ Offering a solution for jitter problems in AES signals, the AES16 incorporates a new Lynx technology called SynchroLock™ that provides extreme jitter tolerance at all inputs. By coupling statistical analysis with low-noise clock generation techniques, SynchroLock is able to extract a very clean clock from AES signals affected by long cable lengths and other noise sources. The clock output of SynchroLock can also be used as a very accurate word clock source for other studio devices.

Extremely Low Latencies:
Glitch-free recording and playback is assured due to the AES16’s large on-board buffers and extremely efficient zero-wait state DMA engine. These features provide tolerance to system latencies and significantly reduce load on the host CPU. Data transfer hardware and software are highly optimized to provide extremely low latencies for ASIO and other real-time applications.


Expandability:
The AES16 includes an LStream expansion port for increasing its I/O capabilities. Connecting a Lynx LS-ADAT adds multi-channel ADAT lightpipe I/O and supports format conversion between AES/EBU and ADAT.

Sample Rate Conversion:
The AES16-SRC model offers eight channels of mastering quality sample rate conversion to accommodate studios running multiple samples rates or signals not locked to ”house sync”.


On-Board Digital Mixer:
The on-board digital mixer offers flexible patch-bay style routing and digital mixing. Zero Latency 32-channel / 32-bit digital mixer with 16 sub outputs. Multiple dither algorithms per channel
