Blastware Operator Manual 4–29
Choosing a geo range depends on the proximity of the transducer to the Event and the expected
particle velocities. On eight channel monitors, set the maximum range for the first standard
transducer in the first text box. Set the maximum range for the second standard transducer in the
second text box.
To choose a maximum range, click on the Maximum Range drop–down menu. Choose a range.
(9) Microphone Channel
The microphone channel records air over pressure. In this section of the Recording Setup dialog
box, you enable the microphone channel, select the channel as a trigger source, and set a trigger
level.
i Enable all microphones
Click on this checkbox to turn the microphone channel on when monitoring. Click on the box
again to clear the checkmark to turn the channel off and not record sound pressure during
monitoring. Note the other checkboxes in the section fade indicating they cannot be selected. On
eight channel monitors, enabling all microphones turns on the microphone channels four and
eight.
ii Trigger Source
Click on this checkbox to use the microphone channel as a trigger source. The Trigger Level
checkbox brightens indicating it can be set.
Note: You can set both the Geophone and Microphone Channels as trigger sources. An Events
activity has to exceed only one of the trigger levels to start recording Event activity on all
channels.
iii Trigger Level
Set a trigger level for the microphone. On eight channel monitors, set the trigger level for the first
microphone in the first text box then set the trigger level for the second microphone in the second
text box.
To set a trigger level, click on the Trigger Level text box. Enter the new level.
Note: In certain situations, the actual trigger level may be lower than the trigger level that
you entered. This is because the monitor coverts the analog signal it receives from the
microphone into digital data, which consists of a series of discrete values. If the trigger
level that you entered does not match one of these values, Blastware automatically sets the
trigger level to the nearest lower value.
