FLS Feedback Locator System, Graphic Equalizers

18.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.

19.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 (20).

20.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!

21.POWER LED:

The power on LED indicator will light when the unit is powered.

22.MONITOR MASTER FADER: Sets the overall level of the monitor signal that is sent to the Monitor Output (9) jack. See page 5.

23.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 Clip 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.
