  • Page 58: Single Setup Algorithms

    300 V 3.0 Owner's Manual Lexicon Single Setup Algorithms Random Hall General Description The 300 incorporates the results of a great deal of research into acoustics and reverberation. Reverberation, or reflected sound energy, gives recorded music a sense of being performed in a real acoustic location.
  • Page 59 The Algorithms and their Parameters Note that none of these shape effects are audible unless RTIM is set short enough. Generally, RTIM should be set to a value of about 1.2 seconds for small rooms, and up to 2.4 seconds or so for halls. SIZE should also be set to a value appropriate to the desired hall size (note, however, that small sizes color the reverberation).15 meters makes a very small room, and 38 meters is useful for a large hall.

  • Page 61 The Algorithms and their Parameters you should set the SIZE control to approximate the size of the acoustic space you are trying to create, before adjusting anything else. The size in meters is roughly equal to the longest dimension of the space. Moving SIZE while a signal is present may cause audible transients on critical material.
  • Page 62 300 V 3.0 Owner's Manual Lexicon Random Hall Tweaks Page SPIN (Randomization) SPIN affects the movement of the reverberation tail. The object of SPIN (and WAND) is to continuously alter the timbre of the reverberant sound. This makes the result more natural, without making the position of instruments unstable.
  • Page 63 The Algorithms and their Parameters SIZE SIZE sets the rate of buildup of diffusion after the initial period (which is controlled by DIFF). It also acts as a master control for RTIM and SPRD. The SIZE control changes a reverb sound from very large to very small. Generally, you should set the SIZE control to approximate the size of the acoustic space you are trying to create, before adjusting anything else.

  • Page 64: Random Ambience

    300 V 3.0 Owner's Manual Lexicon Random Ambience General Description The 300's Random Hall effects are designed to add a cushion of reverberance to recorded music, while leaving the clarity of the direct sound unaffected.

  • Page 67: Rich Plate

    The Algorithms and their Parameters Rich Plate The Rich Plate program is denser, smoother, and less colored than other reverb General Description programs. When used with the SIZE control at around 16 meters, the sound is dense and tight — ideal for percussion. Larger sizes and longer reverb times are suitable for vocals and brass.
  • Page 68 300 V 3.0 Owner's Manual Lexicon Rich Plate Basic Sounds Page RTIM (Reverb Time) This control adjusts the reverberation time of the independent reverberator. The range of action is limited. Be careful — both long and short reverb times may sound unnatural.
  • Page 69 The Algorithms and their Parameters Rich Plate Tweaks Page RAND sets the rate of the randomization process. Plates should generally use RAND (Randomization) low amounts of randomization. SHAP and SPRD work together to control the overall ambience of the reverbera- SHAP (Shape) tion created by the 300.

    300 V 3.0 Owner's Manual Lexicon Split Setup Presets Split Setups are divided into two types: Dual Mono (numbered 201-225 in Setup and their Effects Select mode), and Cascade (numbered 301-325 in Setup Select mode). Most Dual Mono Setups have the left input feeding Machine A, and the right input feeding Machine B.
  • Page 99 The Presets P204 DM: Rev/Comp EA:707:”U”Chamber EB:901:EZ Comp2:1 This preset utilizes a chamber preset on the left input and a compressor preset on the right input. Typically, EZ Comp2:1 should be used at a patch point on the console. If used on an effect send, make sure the fader sends are pre-fade, or a phase error will occur between the fader signal and the return to the console.
  • Page 100 300 V 3.0 Owner's Manual Lexicon P208 DM: *Pch/Pch EA:803 *Up Shift EB:806 Echo Down A true Dual-Mono pitch preset. Going to the Soft knob parameter location (in Setup Select mode) will enable you to advance the delay parameter in the Machine A effect.
  • Page 101 The Presets P212 DM:WideFlang EA:605 OverTheTop1 EB:606 OverTheTop2 This preset can be used with either two mono sources, or one stereo source. One channel glides with a positive resonance, the other flanges with a negative resonance. This preset sounds really awesome with a pre-fade mono send going to each input.
  • Page 102 300 V 3.0 Owner's Manual Lexicon P215 DM:TwoRooms EA:P715 Joe’s Garage EB:P709 Basement Garage band and Basement band. Use with Dual Mono sources and place behind the source. MchA EA:715 Joe’s Garage Two bays, no waiting. Small and bright. MchB EP:709 Basement Tight and short.
  • Page 103 The Presets P220 DM:MyGuitar EA:802 Guit Shift EB:614 Env:Peak Great stuff for either a mono or stereo guitar. Machine B should get a very strong, if not a total, pre-fade signal. MchA EA:802 Guitar Shift This preset offers a moderate amount of micropitch shift(-14c), along with a small amount of recirculating predelay.
  • Page 104 300 V 3.0 Owner's Manual Lexicon P224 DM:Clusters EA:612 Chorus+EKOz EB:604 *3Voice Dlys This preset is intended for “dual-mono” use. The LFO is set to a Triangle shape moving at 2.50Hz. The Soft knob changes the spacing of the delays in Machine B. The Soft knob value is set to 20 when the setup is selected. This means that the Soft knob can go down from its preset value if the application warrants it.
  • Page 105 The Presets P303 CC:Rev->Pch EA:707 “U”Chamber EB:802 Guit Shift This preset runs 70% of a reverb effect into a pitch shift program. The remaining 30% of the reverb effect bypasses the pitch shifter, and appears at the stereo output. Modify BMIX to some lesser value if you want to bypass some of the reverb around the pitch shifter.
  • Page 106 300 V 3.0 Owner's Manual Lexicon P307 CC:Dly->Pch EA:609 Chorus EB:801 Mono Shift This preset combines a stereo chorus passing into a mono shift program. Go to Machine B Effect Edit and modify the Glide Pitch (GLD) parameter. If you want to open the stereo chorus effect, reduce BMIX so that some of the Chorus program passes by the Mono Shift program.
  • Page 107 The Presets P311 CC:Pch->Comp EA:802 Guit Shift EB:901 EZ Comp 2:1 This preset combines a guitar shift effect going into an “easy” compressor effect. The LFO controls the Glide Shift parameter (GLD) in Machine A. The LFO rate is set to 0.16Hz with a sine waveform. MchA EA:802 Guitar Shift This preset offers a heavy amount of micropitch shift (-21c), along with a small amount of recirculating predelay.
  • Page 108 300 V 3.0 Owner's Manual Lexicon P315 CC:*SpaceOut EA:711 *Great Room EB:604 *3Voice Dlys This preset loads two effects, both of which have Soft knob parameterpatches. The Soft knob parameter has a Setup value of 18. AMIX is set to 37%, so that much of the dry signal bypasses the reverb preset and passes through to the delay effect.
  • Page 109 The Presets P319 CC:Rev->Korus EA:706 Big & Short EB:609 Chorus This Setup is a variation of the one above, except that it’s a shorter “close in” effect. There is also a different twist to this Setup preset — L-Meter ballistics are patched to the AMIX Setup parameter. As the signal becomes stronger, AMIX becomes progressively dryer, allowing more of the input signal to pass directly into the chorus effect.
  • Page 110 300 V 3.0 Owner's Manual Lexicon P322 CC:*EKO->Faze EA:805 Env*EKOShift EB:608 Env:Phazer This pitch into Gliding delay Setup is great for the “rockers”. Use the Soft knob parameter to set the timing of the echoes in Machine A. MchA EA:805 Env*EKOShift The Soft knob paramter controls the delay line length, and the L-Meter is negatively patched to the feedback (FBK) parameter so that, when signal is present, delay feedback is reduced;...
  • Page 111 The Presets P325 CC:Spinola EA:609Chorus EB:011Panola This is a sort of "retro" sounding audio effect. The Chorus preset passes into the fast panning Panola effect. Mix post-fader. Kind of like a rotating speaker — only different. The LFO is set to 8.00Hz, with a sine waveform. MchA EA:609Chorus This preset makes use of a small variation in the glide delay to modulate the sound.

Effect Descriptions EP # Name Algorithm Description *Dual Delays Dual Delays Baseline effect with the Soft knob patched to the last two delay lines in the signal path.
  • Page 113 The Presets Chorus Dual Delays This preset makes use of a small variation in the glide delay to modulate the sound. The glide moves between 9.7 and 11.8ms. If the LFO is advanced to values near 1.50Hz to 2.0 Hz, a nice chorusing effect is achieved.
  • Page 114 300 V 3.0 Owner's Manual Lexicon EP # Name Algorithm Description Chamber Split Chamber A great general purpose reverb tail. The size is set to 28.1M (the largest value is 64M) so the density is rather close in. As you adjust size the Rt value will also change.
  • Page 115 The Presets *Drum Rooms Split Chamber Deep and narrow in shape. The Soft knob parameter makes the room “shallower” and gated-sounding. *BigBathroom Split Chamber Bright and clean. Generic WC. Great for solo stuff. or for adding liveness to a track. Soft knob draws out the Reverb Time. *Delay Room Split Chamber This preset offers a nice room reference.
  • Page 116 300 V 3.0 Owner's Manual Lexicon EP # Name Algorithm Description EZ Comp 2:1 Compressor A nice preset to add to an overall mix. You might need to adjust the threshold parameter to make it work for the particular signal you feed it.
