6.10.3.3 Iso-Float
MENU > I/O CONFIG > ISO-FLOAT
Figure 6-15: Iso-Float Menu
To change the Iso-Float setting, press the Inputs or Outputs button, then adjust the value using the rotary
encoder. The current settings are also displayed on the front panel I/O STATUS screen.
The analog inputs utilize Iso-Float transformerless electronic balancing circuitry. This provides electrical isola-
tion from an analog source comparable to that achieved with transformer-based designs. However, pin 1 of
the XLR input connector may be connected to ground within the LM 26 if desired. This option is selected by
using the rotary encoder to toggle between FLOATING and GROUNDED.
It may be necessary to change this setting to resolve ground loop problems when using analog inputs.
