V4 Logger

Configuration - Continued:

Perform Silence Detection

The above screen shot displays the “Perform Silence Detection” section. This is enabled by default

and will flash the “Silence” warning from the Record/Meter section on the left hand column of the

Logger application independently for each audio channel.

If you have a closure device installed such as the DIO 24H PCI card in the following example, you can

assign a closure for either “When any channel is silent” or “When no channel is silent”. Select the

“Edit” box directly to the right of both function and the select the appropriate pin based on your

installed closure device. You can enable one of the two available functions if desired.

The “Allowed Silence Threshold” does not reference from a specific zero reference point. To

accurately set both the “Allowed Silence Threshold” and “Auto Trim” levels, use a known or fixed

output such as a reference tone or tone generator.

Auto Trim

NOTE:

It is strongly recommended NOT to use the auto trim feature on a large number of scheduled

database recordings as this will place a significant amount of overhead on the Logger computer,

especially with 8 and 12 channel versions. Use discretion when applying this feature to ensure

reliability and functionality.
