LS-AES Introduction Thank you for purchasing the LS-AES™! We are proud to provide you with a reliable, professional quality product for your digital audio requirements. This manual provides basic information to help you get started. Additional information is available via our web site and email support. Please refer to the support section at the end of this manual for support contact information.
LS-AES Manual Conventions The term “LynxTWO/L22” is a reference to either the LynxTWO or L22. Both products are compatible with the LS-AES. This manual uses the following typographic conventions: • ALL UPPER CASE text denotes the names of specific connectors. • Italic text denotes emphasis or a warning. • Phrases, such as Start > Programs > Lynx Studio Technology, use the greater than (“>”) sign to separate multiple menu options or icon names that are selected with a keyboard or mouse action.
LS-AES Installation Procedure The following installation procedure must be followed in the order described to insure proper operation. LynxTWO/L22 Driver Verify that the driver installed for your LynxTWO/L22 is Build 049 or later. You can determine the driver version by selecting About Mixer in the Mixer menu of the LynxTWO/L22 Mixer. If you do not have the correct driver version it can be downloaded from the Lynx web site at http://www.lynxstudio.com/download.html.
LS-AES LS-AES Internal Card Installation 1. If you are installing one LS-AES internal card, verify that a shorting jumper is in place on JP4 (refer to figure on following page for location). This will set the board’s LStream bus address to 0. If you are installing a second LS-AES, remove the jumper to set the address of this card to 1.
LS-AES External Connections The following figure depicts the LS-AES circuit board layout and its connector. JP4 - LStream Address Jumper JP1 - Internal LStream Port Digtial I/O Port Connect the included breakout cable to the bracket- mounted Digital I/O Port connector on the LSAES. The XLR connectors on the cable connect directly to equipment with AES/EBU ports. For S/PDIF coaxial connections, use Lynx XLR to RCA S/PDIF adapters (CBL-XFDRM18 and CBLXMDRM18).
LS-AES LynxTWO / L22 Mixer Controls The LStream page of the LynxTWO/L22 Mixer contains controls for installed LStream interface cards. With the LS-AES installed, AES-specific controls are displayed as shown below. The LStream page for the LS-AES contains five panels. The leftmost panel, labeled LStream n, includes controls pertaining to LStream and LS-AES routing. The remaining four panels, labeled Digital I/O n, provide control and status for the LS-AES’s digital inputs and outputs.
LS-AES Digital I/O Panel Description Digital Format Selects AES/EBU or S/PDIF formats. This control affects the electrical characteristics and channel status protocol on the digital input and output SRC Mode SRC Ratio Selects the sample rate converter mode: On - The sample rate converter is enabled on the digital input. The sample rate of the digital input signal is converted to the current rate selected for the host card and LS-AES. Bit-perfect digital transfers are not possible in this mode.
LS-AES LStream Interface to the Host LynxTWO/L22 The LS-AES 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.
LS-AES LS-AES Output Routing As shown below and in the Outputs page of the LynxTWO/L22 Mixer application, 16 output channels are available from the digital mixer. Output channels 1-8 are wired to the analog outputs, AES digital output, loopback registers, and to both LStream ports. Channels 9-16 are wired only to LStream output channels. This connection scheme allows any (or all) of the digital mixer’s output channels to be routed to the outputs of the LS-AES via the LStream interface.
LS-AES LStream Output Channel Group Mapping The mapping of the digital mixer’s output channels to LStream channels can be controlled to accommodate specific I/O configuration requirements. The Output Select control (labeled “1-8/9-16 Select” in the diagram above) allows the destination of the upper eight and lower eight mixer output channels to be altered.
LS-AES LS-AES Input Routing As shown below, the AES data from the LS-AES is routed into the digital mixer of the host card via the LStream 2 Header port. This data can be routed to the record bus using the Input Source Select function within each Input Submixer.
LS-AES WideWire Channel Mapping The WideWire feature of the LS-AES provides alternative multi-wire digital I/O connection modes for compatibility with legacy third party devices. WideWire is enabled in the LStream window of the LynxTWO/L22 Mixer. When enabled, alternate dual and quad wire connections are available, but vary according to the signal sample rate according to the following table: WideWire Sample Rates and I/O Modes Signal Sample WideWire Rate (Hz) ON/OFF 44.1k / 48k Either 88.2k / 96k OFF 88.
LS-AES Clocking and Synchronization The Clock Source control on the LStream page of the LynxTWO/L22 Mixer provides LS-AES clock source selection as follows: Clock Source Selection Slave Digital In 1 Digital In 2 Digital In 3 Digital In 4 Action LS-AES clock is slaved to the host card system clock source. The system clock source is selected on the Adapter page of the Mixer. The word clock derived from the digital IN 1 port is the clock source for the LS-AES and host card.
