LS-ADAT Introduction Thank you for purchasing the LS-ADAT™! 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-ADAT Manual Conventions The term “LynxTWO/L22” is a reference to either the LynxTWO or L22. Both products are compatible with the LS-ADAT. 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-ADAT Installation Procedure The following installation procedure must be followed in the order described below in 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-ADAT LS-ADAT Internal Card Installation 1. With your computer powered down, install the LS-ADAT in a bracket slot adjacent to the LynxTWO/L22 as shown in the figure below. The LS-ADAT must be secured to the computer chassis with a screw. 2. Connect the included 14-pin ribbon cable from connector JP1 on the LynxTWO/L22 to connector JP2 on the LS-ADAT (labeled INT LSTREAM). The connectors on the ribbon cable have polarizing tabs that insert into slots in the mating connectors.
LS-ADAT External Connections The figure below depicts the layout of the LS-ADAT circuit board and its connectors. IN 1 JP2 - Internal LStream Port OUT 1 IN 2 OUT 2 Header for ADAT 9-pin SYNC IN D connector (not shown) ADAT Optical I/O ADAT Optical Interface (lightpipe) Ports The LS-ADAT provides two ADAT optical inputs and outputs. They are labeled on the mounting bracket and in the figure above.
LS-ADAT 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.
LS-ADAT LS-ADAT 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-ADAT via the LStream interface.
LS-ADAT 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-ADAT LS-ADAT Input Routing As shown below, the ADAT data from the LS-ADAT 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-ADAT ADAT Channel Mapping and S/MUX This section describes the mapping of LStream channels to LS-ADAT channels. This mapping varies with sample rate since S/MUX is required to support sample rates above the standard ADAT sample rate of 48 kHz. At 44.1 kHz and 48 kHz there is a one-for-one correspondence between LStream channels and LSADAT channels. All 16 input and output channels are available.
LS-ADAT To insure glitch-free recording and playback using an external ADAT device, the LS-ADAT, host LynxTWO/L22, and external ADAT must run synchronously from a common clock source. There are only two scenarios to consider that satisfy this requirement: 1. The LynxTWO/L22 host card is the clock master. The LS-ADAT and external ADAT device must run in clock slave mode. This case includes host card synchronization to external clocks such as word clocks and composite video. 2.
LS-ADAT 2. From the Transport menu enable Sync Online. With Positioning Protocol enabled, the ASIO application position cursor will track the time code position of the external ADAT device with sample accuracy. Refer to documentation included with your audio editing software for more information regarding ASIO synchronization.
