[. . . ] B) The wire that is colored blue must be connected to the terminal that is marked with the letter N or the color black. C) The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red. [. . . ] Exercise caution when attempting to boost frequencies below speaker system transducer cut-off. Typical sound reinforcement enclosures are not designed for 20 Hz performance, and transducer damage could result from over-boosting low frequencies. Excessive boost at very low frequencies could also limit overall system headroom. NOTE: Superb tonality, absence of feedback and great-sounding systems may not be achievable with any graphic equalizer. all Other system components must be of high quality and designed for the application. No amount of equalization will correct an acoustically bad room or bad microphone/speaker arrangement, or completely correct the response curve of a poor loudspeaker. Unity gain throughout the signal chain can be maintained by recovering lost signal gain at this point. To compensate for this loss, engage the BYPASS switch (5) and compare the signal level with that of the equalized level. Increase the LEVEL control until the equalized level approximates that of the bypassed level. These calibrated, detented controls adjust the amount of cut or boost at their respective frequencies. This switch activates the low-cut filter that rejects frequencies below 40 Hz. This switch allows the signal to bypass all features except the LOW-CUT FILTER (4). When this switch is engaged, the signal is routed from INPUT (10 and 11) though the low-cut filter to the channel's output. This 2-position rocker switch applies mains power to the unit when in the ON position. [. . . ] If the repairs are covered by warranty, Peavey will pay the return shipping charges.
