Sample Clock - Provides control of the Sample Clock and reference. All LynxTWO audio devices on a single card MUST have identical sample rates. Clock Source and sample rates cannot be changed when LynxTWO is playing or recording. Source: Internal � Clock derived from the on-board crystal oscillator. Digital� Clock signal from the DIGITAL IN connector on the L2Sync cable. External� Clock signal from the SYNC IN connector on the L2Sync cable. Header� Clock signal from the board-mounted CLOCK IN header. Video� NTSC or PAL composite video signal from the SYNC IN connector on the L2Sync cable. LStream1 � Clock signal from the LStream port on the L2Sync connector. LStream2 � Clock signal from the LStream port on the Rate: Displays the current sample rate of the LynxTWO. Reference � Provides selection of the clock source reference type from one of the following: Auto � Automatic selection. Valid for Internal, Digital, and Video clock sources. 13.5MHz � 13.5MHz video dot clock. Valid for External and Header clock sources. 27MHz � 27MHz video dot clock. Valid for External and Header clock sources. Word � Word clock. Valid for External, Header, and LStream clock sources. Word256 � 256 times word clock. Valid for External and Header clock sources.
Digital I/O: Sets and displays the formats, modes and status of the digital audio input and output.
Digital Format: Allows selection of AES/EBU or S/P DIF format for input and output. SRC Mode: Sample Rate Conversion Mode SRC On (default): SRC enabled on digital input. SRC Off: Clock Sync: SRC disabled, sample clock source set to source other than Digital. SRC Off: SRC disabled, sample clock source set to Digital. SRC On: Digital Out: SRC enabled on Digital Output. Requires a valid signal on the Digital In to clock the Digitial Output. Digital Input is muted. SRC Ratio: Indicates Sample Rate Conversion Ratio when in �SRC On� modes. Digital In Rate: Measured rate of incoming digital signal. Digital In Mode: Indicates Professional or Consumer input status. LED Indicators: Red and/or Green indicators for: Lock: Red - Receiver PLL not locked; Green - Receiver PLL locked. Validity: Green - Channel status validity bit set. Copyright: Green - SCMS copyright bit set (consumer mode). Original: Green - SCMS original bit set (consumer mode). Non Audio: Green - Channel status non-PCM bit is set, e.g. Dolby Digital, DTS. Parity: Red - Parity error detected. Confidence: Red - Signal quality degraded. Biphase: Red - Bi-phase coding error detected. CS CRC: Red - Channel Status CRC error detected. Q CRC: Red - Q Channel subcode data CRC detected. Continued on the next page...
