FLS (Feedback Locator System):

These LEDs illuminate to indicate the frequency band of highest energy. When feedback
occurs, this system will automatically indicate the graphics slider to use to lessen or eliminate
feedback. (NOTE: These LEDs illuminate with any audio signal, not just during feedback.) If
feedback occurs, pull down the slider under the brightest LED.

GRAPHIC EQUALIZERS:

These nine-band equalizers are fixed on one-octave centers. They are designed for 12 dB of
cut and 12 dB boost. They are connected directly to their power amplifier inputs. The signal
sent to each equalizer is determined by the System Mode Switch (19).

SYSTEM MODE SWITCH:

This switch is used to configure the XR 800F+ as either a stereo or dual mono amplifier. It is
recessed to prevent accidental switching during a performance. Use a non-metallic object to
change the switch position (e.g., a toothpick). The XR 800F+ is shipped from the factory in
the default setting of Left Main to the upper EQ and Right to the lower EQ. When this switch
is depressed it switches the lower EQ to (mono) PA Left + Right. The upper EQ then
becomes the Monitor signal only, creating an entire PA and Monitor mixing system in one
small, easy-to-carry package. And this change is accomplished without a single patch cord!

POWER LED:
The power on LED indicator will light when the
unit is powered.
MONITOR MASTER FADER:
Sets the overall level of the monitor signal that is
sent to the Monitor Output (8) jack. See page 5.

SIGNAL LEVEL METERS:

Displays overall level of either the L and R signals or
the Mon and L+R (mix) signals. The System Mode
Switch determines which mode the meter will operate
in. Red Peak LEDs are located at the top of each
meter to indicate clipping. A clipped signal may
damaged your speakers. To prevent possible
speaker damage reduce the respective fader level.
