[. . . ] 24-BIT DIGITAL SIGNAL PROCESSOR USER'S MANUAL May be covered by one or more of the following: U. S. Patents #4538297, 4647876, 4696044, 4745309, 4881047, 4893099, 5124657, 5263091, 5268527, 5319713, 5333201, 5402498, 5493617 and 5638452. Foreign patents pending. Your Intellifex XL has been tested and complies with the following Standards and Directives as set forth by the European Union: Council Directive(s): Standard(s): 89/336/EEC Electromagnetic Compatibility EN55013, EN50082-1 This means that this product has been designed to meet stringent guidelines on how much RF energy it can emit, and that it should be immune from other sources of interference when properly used. Improper use of this equipment could result in increased RF emissions, which may or may not interfere with other electronic products. [. . . ] Reflections in a hall are much longer than a typical room, as the length of time it takes for the sound waves to travel from one surface to the next is greatly increased. Stadium reverb simulates the characteristics of a large stadium or arena and should be used with large amounts of predelay and high frequency damping. Dual reverb is unique in that it allows for the left and right channels to be processed independently one another. For example, the Predelay for the left channel can be set at 100mS while the Predelay for the right channel can be set at 200mS. This results in reverb output from the left channel 100mS before reverb is output from the right channel. 13 Reverb Parameters Parameter Description This determines whether the input to the reverb section is active (passing a signal) or muted (not passing a signal). This determines the level of the reverb signal at the output relative to the direct signal and any other effect signals. This specifies the length of time that the reverb signal will sound before it has completely faded out (or until its echoes have been ultimately absorbed by the boundaries within the given "room"). The maximum length of this decay will vary dependent upon which reverb type is active. High Frequency Damping is used to control the amount of high frequency information in the reverb signal. This determines the amount of low frequency information in the reverb signal. This allows you to pan the direct input signal to the reverb section to the left or right - allowing for only the left or right channel to be reverberated when used with the Dual reverb type, or, for one channel to be reverberated to a greater degree than the other. It is adjustable from 0 to 100-- where "0" = full left, "100" = full right and "50" = center. This determines the amount of time after a signal is input to the Intellifex XL that the left channel signal will be input to the Reverb. Delaying the reverb signal provides greater separation of the input and reverb signals and helps to increase the apparent size of the Room, Hall, or Stadium. This determines the length of time after a signal is input to the Intellifex XL that the right channel signal will be input to the Reverb. Gating the reverb signal closes down the decay of the reverb very quickly after a prescribed amount of time (most commonly a very short period of time). This effect is often used on drums (particularly snare drums) to produce the effect of a much fatter percussive sound. Note that gating on the Intellifex XL acts on the reverb decay, not on the reverb output as on many other units. The Gate Decay parameter determines how quickly the gate will close down the reverb decay after the reverb has sounded for the specified time. The Gate Threshold determines the threshold point at which gating will take place. When the signal is below this threshold point for a period of time, the reverb will be gated. When the input signal peak rises above this threshold, the gate will open and reverb will be heard. [. . . ] XXH - 240 data bytes for 80 strings, 256 data bytes for string 81, 12 data bytes for string 82, MSB = 0 YYH - Check Sum byte, ("Exciusive Or" of data bytes, MSB=0) F7H - End of Exclusive byte The first 80 data strings are very similar to a preset dump data string except for the command byte. 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 XL if Check Sum bytes do not match, or if a status byte (MSB = 1) is received when a data byte was expected.
