Line In Flat Response Mode:
On the top of the unit is a new feature, audio dBV level. The readings
and the display help determine what level of signal is Coming from the
house feed. Levels between -10dBV and +4dBV are considered to be
line level signals. A poor loop system sound often comes from a very
low level building feed. This input uses the last mode on the FSM and
displays an accurate level which can then be demonstrated to the
building. We advise a level between -10dBV and 0dBV.
To use this feature cycle through the various mode un-til you see Line
In Flat Response on the display. Now connect up the XLR adapter
which has an XLR female on one end and an 1/8” TRS connector on the
other end. If you wish to make up your own adapter use the following
