Lynx AES16e-SRC

Lynx Studio Technology's AES16e-SRC 192 kHz Multichannel AES/EBU PCI Express Interface integrates digital consoles, multi-channel A/D and D/A converters, and hard disk recorders with PCI Express-equipped computer-based workstations, while offering 16 channels of high quality sample rate conversion. The AES16e-SRC offers unprecedented AES/EBU channel capacity and routing flexibility in a x1 PCIe card format. With support for up to 16 channels of input and output at sample rates up to 192 kHz, the AES16e-SRC turns your computer into a powerful digital router or patchbay with extensive flexibility with minimal cabling. Most importantly, the AES16e-SRC supports the single-wire 192kHz standard and is compatible with existing dual-wire AES/EBU devices. Up to eight AES16es can be installed in a single computer (Windows).

The Lynx AES16e-SRC PCI Express Card builds on the capabilities of Lynx's popular AES16 with updated features and the benefits of the PCI Express interface. The architecture and higher bandwidth of PCI Express reduces bottlenecks and overhead, which provides higher performance for computer-based, high-end audio operations.

The AES16e-SRC PCI Express card offers 16 channels of 24-bit AES/EBU digital audio at a 192kHz sample rate in both single-wire and dual-wire AES modes. Designed to integrate digital consoles, multichannel A/D and D/A converters, hard disk recorders, digital audio workstations, and other digital audio equipment, the AES16e-SRC is compatible with both Windows and Macintosh operating systems. The Lynx AES16e-SRC PCI Express Card also provides you with 16 channels of sample rate conversion (cable sold separately).


SynchroLock:
Offering a solution for jitter problems in AES signals, the AES16e-SRC incorporates Lynx word clock 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 AES16e-SRC '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 AES16e-SRC 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 AES16e-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 available per channel.
