[. . . ] WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. [. . . ] FUSE: This is the main safety fuse for the AC line voltage. Only replace the fuse with one of the exact same type and rating. The POWER AMPLIFIER SECTION will explain the proper method of connecting your XR 800F+ to your speakers. This is a very versatile area of the XR 800F+. However, it is important that you follow the precautions to insure safe operating impedances and avoid improper connections. PARALLEL LEFT/RIGHT SPEAKER OUTPUTS: 4 4 These 1/4" jacks are the outputs for the two internal amplifiers. Two cabinets can be connected to each amplifier, as long as the combined impedance of the cabinets is not less than 4 ohms. ) The outputs from these jacks are determined by the System Mode Switch (19). This section is often overlooked but adds the most versatility to the XR 800F+. When used to its fullest potential, an extraordinary variety of wiring configurations can be made. These connections allow for devices such as outboard effects, power amps, monitors, and virtually any other type of line level audio device to be patched in to the XR 800F+. This control allows effects to be heard from the stage via the monitor. 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. 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. 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! [. . . ] PEAK LED: Indicates when the signal input is too strong and signal clipping is present. A clipped signal may damage your speakers. cHANNEL FADER: Sets the signal level sent to the Left and Right bus. (This feature can also be found on Channels 7 through 9. [. . . ]
