Silence detect delay
Silence detect or threshold delay can be set at the card edge or via Statesman. The control
slider sets the silence detect delay from 0 to 128 seconds for the amount of time a signal is
allowed to remain below -50dB with respect to Full Scale before a silence error is flagged. To
prevent false alarms during quiet passages there is minimum delay period of approximately
four seconds in which silence must be maintained before the delay timer is initiated.
Note: This minimum delay will become significant at short delay settings and it may be
necessary to take it into consideration when using a short delay setting.
Factory Reset
The factory reset can be used to return the TANDEM HD-20 to it default condition. It should
be noted that if a factory reset is carried out the final routing will depend on any sub-PCBs
fitted and all preset configurations will be erased.
