PRECAUTIONS NOTE: IT IS VERY IMPORTANT THAT YOU READ THIS SECTION TO PROVIDE YEARS OF TROUBLE FREE USE. All warnings on this equipment and in the operating instructions should be adhered to and all operating instructions should be followed. [. . . ] When using a moderate amount of regeneration, switching out the delay with the input muted will generate a non-delayed signal which will play over the decaying regenerated signal which continues on after the delay is switched out. Muting the output (Post) of the delay results in the delayed signal being immediately turned off when the delay is switched out. This means that delays and regeneration will not continue once the delay is switched out. If the output were not muted, signals input before switching the delay out would be allowed to regenerate - even after switching out the delay. It is also possible to mute both the input and output (Both) so that no signal enters or exits the Delay section when it is not switched in. Level 1 and Level 2 These are individual level controls for each of the two delays available in the Delay section. These are not the same as the Delay Level parameter found in the Mixer function (which adjusts the overall level of both delay signals). 15 Pan 1 and Pan 2 This allows for the panning of each delay to the left or right output, if desired. The Pan parameter is adjustable from 0 to 100 - where 0 = full left, 100 = full right and 50 = center. Dly Time 1 and Dly Time 2 These parameters determine the amount of time after a signal is input that the delayed signal will begin to reproduce the input signal. Regen 1 and Regen 2 This parameter is provided for each delay and determines the number of times the delayed signal will repeat itself. D Type The Delay Type parameter determines whether the Stereo, Ping-Pong or 2-Tap delay type is currently active. Dl Hf Damp Delay High Frequency Damping determines the amount of high frequency content in the delayed and regenerated signals. Higher amounts of damping will result in less high frequency information in the delayed signal. 16 D. DUCKER SECTION The process of Ducking enables the user to suppress the level of a given signal or effect dynamically, dependent upon the presence of another signal which is desired to be prominent. The Ducking feature of the Intellifex LTD works in conjunction with the Delay and Reverb sections to attenuate the delay and/or reverb level while a phrase is being played (resulting in a less cluttered, more intelligible sound), yet return each to its original level when the phrase ends - thus allowing for the full decay of the delayed and/or reverberated signal. DUCKER PARAMETERS Ducker In the HUSH; Delay; Ducker configuration, this parameter determines whether the Ducker is off or on. In the HUSH; Chorus; Delay; Reverb and HUSH; Pitch Shift; Delay; Reverb configurations, this parameter determines whether the Ducker is either (A) off, (B) operating on the delay, (C) operating on the reverb, or (D) operating on both the delay and reverb. Sensitivity This parameter determines the threshold point above which the ducker will begin attenuating the delay and/or reverb signal. Until the input signal reaches this level, the delay/reverb signal will not be affected. Attenuation This parameter determines how much the delayed signal is attenuated (muted). It may be set for only a slight change in signal level or it can completely attenuate the delay/reverb signal so that no delayed or reverberated signal passes while ducking is active. Release Rate This parameter is adjustable from . 2 seconds to 9 full seconds, and determines the length of time it takes for the muted delay signal to return to its original signal level after the input signal falls below the threshold point set by the Sensitivity parameter. 17 E. PITCH CHANGE SECTION Pitch Change effects involve splitting the input signal into at least two separate signals, then modifying the pitch of one signal and mixing it back together with the unaltered direct signal. The Intellifex LTD offers two types of pitch change effects: Chorus and Pitch Shift. CHORUS The Chorus effect is achieved by using one or more delayed signals, detuning these delayed signals (slightly changing their pitch) then modulating this detune effect so that the amount of pitch detune is constantly varying. Using many delayed signals at different delay lengths - as well as using different detune amounts, modulation rates and modulation depths for each delayed signal - results in a rich, spacious stereo chorused signal. CHORUS PARAMETERS Level (Individual Voices) This parameter adjusts the volume of the delayed signal relative to the other voice(s) of the effect and is included in the parameter list for each voice (or each delay signal) of both the 8-Voice and 4-Voice Chorus effects. [. . . ] The first data string for a user data dump will contain the command byte 2AH. Data string 81, which is the program mapping, will contain 256 data bytes. Data string 82, which is miscellaneous data, will contain 12 data bytes. Error Messages "RECEIVE ERROR" - This message will appear on a receiving Intellifex LTD if Check Sum bytes do not match, or if a status byte (MSB = 1) is received when a data byte was expected. This message also appears if a knob is turned or a button is pressed during reception. [. . . ]
