Use the BOTTOM LINE knob to select the mostsuitable ratio. A Simple, equal 1 to 1 ratio is thefirst entry in the table. This setting sends a delayof equal time to the left and right output chan-nels. The number in the left column of the tableindicates the ratio of the delay time that will be inthe left channel versus the number in the rightcolumn.For example, if a delay of twice the time isrequired in the left channel compared to theright, select the 2/1 option. The final 1/OFF andOFF/1 options will result in no delay being heardin the channel indicated by the ‘OFF’.Note: Selecting a 1/1 ratio will produce a monoeffect regardless of the Stereo width settingsince the timing of the echos are equal.NOTE: The left / Right delay ratio will only be heard if using a Stereosignal source.The Reverb EffectThe Reverb Effect is an electronic simulation of a room or building thatis acoustically reflective. When a sound is made in a room or largebuilding, there are sound reflections from all directions. When a Reverbeffect is applied, it is these reflections of the sound that are beingadded.To adjust the controls for the Reverb effect use the UP and DOWNarrow until the Reverb LED next the Reverb label is selected. Turn theLEVEL knob until the Reverb effect is present.If either the TOP LINE, or BOTTOM LINE knob is adjusted the displaywill alter to display the Reverb Type and Reverb Decay as shownbelow.Rev Type: L-HallRev Decay: 59Reverb TypeDifferent types of rooms and halls have different acoustics, thereforedifferent Reverb characteristics. The Reverb processor features six dif-ferent Reverb types. These range from a small room to a large hall.The type are : Chamber, Small Room (S-Room), Large Room (L-Room), Small Hall (S-Hall), Large Hall (L-Hall) and Grand Hall (G-Hall).Turn the TOP LINE knob to experiment with different types of Reverb,noting how different ‘rooms’ affect the acoustic properties of the sound.Reverb Decay TimeThis is the time it takes for the Reverb to die away after the originalsound has decayed. Very acoustically reflective rooms (like those withmetal or glass surfaces) tend to have long decay times and non reflec-tive rooms have short ones. Turn the BOTTOM LINE knob to experi-ment, lower value settings will introduce short decays and higher valuesettings will create long decays.The MENU button is non active when the Reverb option is selectedsince there are no additional Reverb parameters.The Chorus EffectThis effect was originally designed to simulate the sound of many peo-ple singing together in unison (hence the name Chorus) in contrast to asingle voice. Instrumentally, consider the sound of a 12 string guitarcompared to a 6 string guitar. The very slight detuning of the individualstrings gives a richer quality to the sound.Chorus is an effect produced by mixing a continuously delayed versionof the audio signal back with the original. The timing of the delayed ver-sion is very small and is controlled by the Chorus’s own internal LFO(not to be confused with the two LFOs available on the front panel).The characteristic swirling Chorus effect is the result.The Chorus is also capable of behaving as a Phaser. The way aPhaser works is entirely different to the Chorus. A portion of the audiosignal is split off and phase shifted at certain frequencies. It is thenmixed back with the original signal to generate the characteristic swish-ing effect.To adjust the controls for the Chorus or Phaser effect use the UP andDOWN arrow until the Chorus LED next the Chorus label is selected.Turn the LEVEL knob until the Chorus effect is present.If either the TOP LINE, or BOTTOM LINE knob is adjusted the displaywill alter to display the Chorus Type and Chorus Rate as shown below.ChorType: ChorusChor Rate: 25TypeThe type determines whether the Chorus is behaving as a standardChorus or as a Phaser unit. Turn the TOP LINE knob to switch betweenChorus and Phaser types.RateThe Rate controls how fast the dedicated Chorus LFO is oscillating. Afairly slow speed is recommended. Higher speeds tend to introduce avibrato like quality to the sound. Turn the BOTTOM LINE knob to exper-iment.To access the remaining controls of the Chorus / Phaser effect proces-sor, press the MENU button. The BANK PAGE UP/DOWN buttons maynow be used to scroll forwards and backwards through any additionalMenu screens.Mod Depth : 95Mod Centre : -10Mod DepthThe Chorus has it own LFO which is continuously changing the delaytime. Mod Depth sets how much of the fixed delay time is being modu-lated. Large amounts of modulation will produce a more noticeableeffect. Moderate amounts are recommended. Turn the TOP LINE knobadjust the Mod Depth.Mod CentreThe Stereo Chorus can be thought of as two continuously variabledelays. The delay variations are being controlled by the Chorus dedicat-ed LFO. The LFO is constantly moving the two delay amounts fromminimum to maximum. When one delay is at max, the other is at min(hence the stereo effect).DETAILED OPERATIONThe Reverb Effect - The Chorus Effect• 24 •Delay RatiosLeft/Right1/14/33/43/22/32/11/23/11/34/11/41/OFFOFF/1
