Features
LynxTWO 192 kHz Multichannel Audio Reference Interface
LynxTWO-A Four Analog Inputs and Four Analog Outputs
LynxTWO-B Two Analog Inputs and Six Analog Outputs
LynxTWO-C Six Analog Inputs and Two Analog Outputs

The LynxTWO family of PCI cards were Lynx’s first 192 kHz audio
products. Introduced in 2000, these three versatile cards offered
192 kHz analog audio and 96 kHz digital audio with world-class
converters and time code synchronization on board. With
performance that exceeds many stand-alone converters, LynxTWO has
set the standard for signal purity, versatile synchronization,
powerful hardware mixing, and extensibility to support a variety
of multichannel formats including ADAT and multiple AES/EBU or
SPDIF.

The three models offer different analog I/O configurations for
versatility and ease of use. The basic LynxTWO-A model, with four
analog inputs and outputs, is intended for general usage. LynxTWO-
B, with two analog outputs and six analog outputs, is an excellent
choice for playback of 5.1 audio or any application where six
outputs are necessary, often precluding the need for a second or
third card. With its six analog inputs and two analog outputs, the
LynxTWO-C is an excellent choice for remote recording systems.

LynxTWO’s powerful 16-channel mixer allows extensive routing, control
and metering with excellent visual reference. With the latest
software, you can mix up to four inputs to any of 16 outputs. In
addition to the inputs and outputs on the LynxTWO, the mixer
incorporates program material from the optional LS-ADAT or LS-AES
daughter cards or from Aurora converters.

With a design very similar to that of Lynx’s highly acclaimed Aurora
converters, LynxTWO delivers near Aurora-quality specs and
performance in the compact PCI card format. In fact, using the
optional LynxTWO/Aurora Interface Kit, your LynxTWO can act as the
computer interface and front end for the Aurora converter.
If you want the same audio quality of the LynxTWO, but only need two
channels and do not need SMTPE capabilities, check out the L22.
