A/DA Final Phase
ADA Final Phase
A/DA Final Phase represents the latest in phase shifter technology. The
FINAL PHASE is capable of producing a very broad range of sound
colorations, dramatically enhancing the effect of any amplified musical
instrument, voice or percussive instrument.
Comes with a power cord for USA 120V ac power.
phasing takes place when a signal is divided, one half slightly
delayed, then remixed with the original signal. This “delay” only
occurs at certain frequencies and is referred to as phase shift (when
the delay occurs at all
frequencies, the effect is called flanging). When the phase shift of
the delayed signal differs by 180 degrees relative to the original
signal, a cancellation, called a notch, is generated when they are
remixed. The FINAL PHASE generates 5 notches, which when moved back and
forth across the sound spectrum, for example, produces the classic
rotating speaker effect.
2009 Reissue A/DA Final Phase is designed by the original designers of
the late 1970s A/DA Final Phases using very similar parts and exactly
the same parts in the all-analog signal path. The differences between your Reissue Final Phase and the original A/DA Final Phases are:
- The Reissue has true “hardwire” bypass and the originals did not.
Reissue Overdrive (distortion) has been re-voiced to get a more modern
sounding distortion, while keeping the original distortion tone and
feel by backing off the new Overdrive Control. In effect we have added an “11” to the Overdrive. As you approach the maximum setting, the bass resonance increases and the highs become more complex.
printed circuit board (PCB) has a different layout, but is all
through-hole design, using full-size carbon film resistors and
precision polyester film capacitors for the highest quality signal
path. There are no surface mount components in your Reissue Final Phase.
A/DA FINAL PHASE OPERATING NOTES
1. The cord from the instrument or microphone plugs into the IN jack.
2. The cord from the amplifier plugs into the OUT jack.
AC/DC converter. The special coax plug on the AC/DC power converter
plugs into the jack marked POWER. Use A/DA PS-8001 power converter
only. There is no need to remove batteries when using the converter,
since they are automatically bypassed.
CONTROL input accepts either the A/DA CONTROL PEDAL A or a 0 volt to +5
volt control voltage. In either case the connection should be made with
a 3-conductor stereo-type cable. To obtain maximum phasing range from
the CONTROL input, set the RANGE CONTROL knob fully counterclockwise.
This setting defeats the automatic sweep functions (SWEEP RATE and
SWEEP MODULATION). However, they may be mixed with the signal applied
to the CONTROL input by turning the CONTROL RANGE slightly clockwise.
SWEEP RATEControls the speed at which the phase Shift. Effect moves up and down the sound spectrum.
A Variable speed oscillator that adds to or modulates the main
sweep, producing shimmering, vibrato-like effects, asymmetrical sweep
patters, multiple phaser effects, modulated sweep, syncopated beats,
Determines the limits of the automatic sweep functions (SWEEP RATE
and SWEEP MODULATION), with maximum range at the full clockwise
setting. When using the CONTROL input (as mentioned above), the RANGE
CONTROL gives maximum range to the CONTROL input when set to full
A regenerative feedback control that adds emphasis (peaking) to the
phasing effects. Sounds ranging from hollow tubes to intensified “wahs”
Adds a variable amount of distortion to the input signal, smooth “tube amp” harmonic distortion are easily produced.
Switches electronics of FINAL PHASE into or out of operation.
Engages or bypasses the electronics of distortion. Responds only when electronics of phase shifter are operating.
