LynxTWO / L22 Mixer Controls
The LStream page of the LynxTWO/L22 Mixer contains controls for installed LStream interface
cards. With the LS-ADAT installed, ADAT-specific controls are displayed as shown below. The
description for each control is included for reference.
Device ID LStream device identification
Output Select
Controls routing of the eight upper and lower
digital outputs from the host card to LStream
channels.
Clock Source
Controls selection of the clock source for the
LS-ADAT.
Position
Time code frame address decoded from ADAT
SYNC IN port. The frame rate is 30 fps.
Cue Point
Enable
Enables sample accurate time code
synchronization starting at the time code
address specified in the Cue Point box.
Cue Point
Text box for entry of time code Cue Point
frame.
All LStream controls are described in detail later in this manual.
LStream Interface to the Host LynxTWO/L22
The LS-ADAT communicates with the host card through Lynx’s proprietary LStream interface.
LStream is a high-speed TDM serial interface that supports up to 16 channels of bi-directional 24-bit
audio data with synchronization and control information.
The individual channels of the LStream interface are integrated into the host card’s on-board digital
mixer. This allows LStream data, in this case ADAT data, to be freely routed and mixed with the host
card’s analog and digital audio I/O. Currently, the architecture of LynxTWO/L22 digital mixer
supports a maximum of 16 input and 16 output channels that can assigned as needed to the available
physical I/O’s. Controlling the digital mixer requires an understanding of the LynxTWO/L22 Mixer
application. Please refer to the User’s Guide included with the product you own for further details.
The number of channels supported on one LStream connection varies with sample rate as follows:
Sample Rate Speed Number of LStream
Channels
44.1/48 kHz Single 16
88.2/96 kHz Double 8
176.4/192 kHz Quad 4
It just so happens that the LStream channel capacity meets the requirements for handling the high
sample rate S/MUX features of the LS-ADAT. This will be discussed in more detail later.
