Lynx Studio Technology Lynx L22 2 Channel PCI Audio InterfaceThe Lynx L22 is a professional audio interface card intended for use in the most demanding audio recording, post-production, broadcast and measurement applications.
Based on the LynxTWO technology, the L22 can capture or generate signals beyond the audio band up to 100 kHz with extreme accuracy. Using proprietary circuit topologies and custom components in the analog stages coupled with the latest converter technology, the L22 achieves a 115 dB dynamic range. Most importantly, advanced noise-rejection design techniques are incorporated to maintain this performance in real world use from computer to computer. Glitch-free recording and playback is assured due to the L22’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.
The onboard digital mixer is extremely flexible allowing the L22 to adapt to any studio or workstation configuration. Each of the mixer’s 16 outputs is capable of mixing signals from 16 physical inputs or 16 playback tracks with 32-bit precision. A choice of dither algorithms is available on each input to mask low-level artifacts while reducing word widths to 8, 16, or 20 bits.
The L22 provides I/O expansion via its two Lstreame ports. Combined, these ports allow 16 channels of additional I/O from external ADAT, AES/EBU, or TDIF devices. The ports can also be used to route data and synchronize to other L22’s or LynxTWO’s to create high channel-count systems.
As with other Lynx products, the L22 provides unprecedented compatibility with a wide range of platforms and operating systems. Lynx device drivers are developed in-house to insure quality and robustness.
