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. Often a poor loop system
Sound comes from a very low level facility feed.
This input uses the last mode on the FSM and dis-
plays an accurate level which can then be demon-
strated to the facility. We prefer a level between -
10dBV and 0dBV.
To use this feature cycle through the various mode
until 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
