Sample Rate LEDs
96, 48, and 44.1 (kHz) represent the nominal sample rates. The Custom LED illuminates
to indicate other rates within the range 31–100 kHz.
The Pull-Up or Pull-Down LEDs illuminate when the sample rate is set to a Pull-Up
or Pull-Down rate of one of the three nominal or Custom rates.
The Dual Ref LED illuminates to indicate that the time code and sample rate clock
sources for the SH612 each reference a separate external signal. This means that syn-
chronization must be accomplished externally to the SH612 or the signals may drift.
The SH612’s response to drift varies depending on the mode. Drift is allowed in the
Jam Continuous (1% only) and Jam Once modes. It is only in either of these two
modes that the Dual Ref LED lights. In all other cases the LED is not lit.
The TC Lock LED indicates time code lock status:
• Solid LED: Locked to valid time code signal
• Flashing LED: No lock because expected time code signal not present
• Unlit LED: SH612 is generating internal time code
