Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] The stereo channels have 4-band EQ: low shelving, low-mid and high-mid peaking, and highshelving. It'sprobablyalltheEQyou'lleverneed!Shelving means that the circuitry boosts or cuts all frequencies past the specified frequency. For example, the low EQ boosts bass frequencies below 80 Hz and continues down to the lowest note you never heard. Peaking means that certain frequencies form a "hill" around the center frequency. We've designed a lot of boost and cut into each equalizer circuit because we know that everyone will occasionally need that. Equalize subtly and use the left sides of the knobs (cut), as well as the right (boost). If you find yourself repeatedly using full boost or cut, consider altering the sound source, such as placing a mic differently, trying a different kind of mic, changing the strings, or gargling. Most of the root and lower harmonics that define a sound are located in the 100 Hz­8 kHz frequency range, and you can create drastic changes with these two knobs. Many engineers use mid EQ to cut midrange frequencies, not boost them. One popular trick is to set the mid fully up, turn the frequency knob until you find a point where it sounds just terrible, then back the mid down into the cut range, causing those terrible frequencies to disappear. 7 and 8) The high mid EQ provides up to 15 dB of boost or cut at 2. 5 kHz, and it is also flat at the detent. 7 and 8) The low mid EQ provides up to 15 dB of boost or cut at 400 Hz, and it is also flat at the detent. It was going to be, but after much discussion among the engineers, it was decided not to add it after all. It would have been good though.

OVERLOAD (OL) LED This LED will come on when the channel's input signal is too high. If the LED is coming on regularly, check that the gain switch [32] is set correctly for your input device: Set it to low if you are using a line-level input, or high if you are using a microphone, or instrument-level input (channel 5 and 6 only). OUT (HIGH) Gain = 45 dB 31. CHANNEL LEVEL This adjusts the level of each channel onto the main mix. [. . . ] This effect simulates the sound of a vocal or instrument being recorded twice (double tracked) on a multi-track recorder. This lets you both thicken your sound with the chorus effect while adding warmth and spaciousness thanks to the smooth reverb. Provides a vibe that is similar to chorus without the subtle swirl. 14 Chorus + Reverb 15 Doubler 16 Tape Slap This effect provides a single, relatively rapid delay of the Often used on vocals for a 1950's era feel, or on original signal, with the added warmth that vintage tape- guitars for a surf-type tone. These 6 delay presets provide one (delay 1), three (delay 2), or six (delay 3) repeats of the original signal. [. . . ]
