When the switch is depressed, the post-pan-pot signal is routed to the Sub-group (lef[...]

10 WIRING UP Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide rang e of BALANCED or UNBALANCED lo w-lev el signals, whether from deli- cate vocals requiring the best lo w-noise perfor mance, or dr um kits needing maximum headroom. Professional dynamic, condenser or ribbon mics are best because these will be LO W IM[...]

11 A ‘Y’ lead ma y be required to connect to equipment with separate send and retur n jacks as sho wn below: Stereo Inputs STEREO 1/2 These accept 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the ‘cold’ input. Use these inputs for sources such as ke yboards, dr um machines, synths, tape machines or a[...]

12 Polarity (Phase) Y ou will probably be familiar with the concept of polarity in electrical signals and this is of par ticular importance to balanced audio signals. Just as a balanced signal is highly effective at cancelling out unwanted interference, so two microphones picking up the same signal can cancel out, or cause serious degradation of th[...]

Professional dynamic, condenser or ribbon mics are best because these will be LO W IMPEDANCE. Y ou can use low-cost HIGH IMPED ANCE mics, but the lev el of background noise will be higher . If y ou t[...]

18 STEREO INPUT CHANNELS 1 INPUTS STEREO 1/2 These inputs accept 3-pole 6.35mm (1/4") jacks. Use these inputs for sources such as ke yboards, dr um machines, synths, tape machines or processing units. The inputs are BALANCED for lo w noise and top quality from professional equipment, but y ou can use UNBALANCED sources b y wiring up the jacks [...]

26 REVERBS Rev erberation (or “reverb” for shor t) is the complex effect created by the wa y w e perceive sound in an enclosed space. When sound wav es encounter an object or boundar y , they don’t just stop. Some of the sound is absorbed by the object, but most of the sound is reflected or is diffused. In an enclosed space, re verb is depend[...]

27 Reverse Reverb Rev erse reverb w orks in the opposite fashion from nor mal re verb . Whereas a normal reverb has the loudest series of reflections heard first that then become quieter ov er time, the Rev erse rev erb has the softest reflections (essentially the tail of the rev erb) heard first, and then gro ws louder ov er time until they abrupt[...]

28 Shape This control helps give a sense of both room shape and room size. Low v alues for Shape keep the majority of sound energ y in the early par t of the re verb tail. High v alues mov e the energy to later in the rev erb , and are helpful in creating the sense of a strong rear wall or “backslap. Boing This is a unique parameter to the Spring[...]

29 increase the time between repeats. Range 0-72. See the Effects Data Char t for exact note v alues. Feedback Controls the number of dela y repeats by feeding the dela y output signal back into the dela y input. This creates a series of dela y repeats, each slightly attenuated until they become inaudible. Higher settings create more repeats; low e[...]
