Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. [. . . ] This is roughly where many "semi-parametric" EQs are set. The frequency controls determine the center point at which the cut/boost will take action. Think of the bandwidth control affecting the range of tones being acted upon and the frequency control determining the center point of those tones. The electric bass generates notes with frequencies ranging from about 30. It may help you to think of frequencies as notes on your instrument or notes that you sing. By doing this, the concept of bandwidth and frequency becomes easier to understand. The bandwidth control determines the number of notes being affected and the frequency control determines the center of that range of notes. Below are a few more pitches with their corresponding frequencies: Four-string bass: E string = 41. This knob controls the overall volume level of the system. DDT should be enabled at all times to protect your speakers. The LED is green when the power switch is in the "on" position. During normal operation, this LED also acts as a DDT/clip indicator. The LED illuminates red when DDT speaker protection is taking place or when the power amp is clipping (if DDT is disabled). Under normal operation it should be in the center (zero) position. If hum or noise is present with the ground switch in the center position, place the ground polarity switch to positive or negative (+ or -) to minimize hum. Should a problem continue, consult your authorized Peavey dealer, the Peavey factory or a qualified service technician. Note: The ground switch is not functional on 220/240 Volt models. Use this switch to restore power to the unit when the internal breaker is tripped. Turn the power switch to the off position before resetting the breaker. To reset, push the reset button in and release it. Turn the unit back on and confirm that the power LED is on. If the breaker is tripped again upon power-up, consult your authorized Peavey dealer, the Peavey factory or a qualified service technician. [. . . ] Its signal is buffered off the input jack so it is just like plugging directly into the tuner. This 1/4" jack is provided for connecting an instrument to the amp from behind the rack. It is just like plugging directly into the front panel input jack. note that the front panel input jack overrides the rear panel input jack. [. . . ]
