THE PAN
This part of 1601E is quite revolutionary. There have of course been auto-panning devices before, which could use an LFO to move
a signal around the stereo field, but none which could trigger the LFO from a BPM analyser and certainly none which could move
different frequency bands to different pan positions at the same time. The unique Spacial Panning System featured in 1601E can
actually split the incoming signal into three bands (low, mid and high -as normally used by DJs) and then move these bands' pan
positions independently.
With SPS Off, the Pan works in a more conventional fashion on the entire signal, moving it around the stereo position at the
determined speed, giving you a standard auto-pan controlled by the BPM analyser. As you increase the SPS amount, it will start to
move two bands around in the stereo field whilst holding the third user-definable band stationary and as SPS reaches full, all three
bands will be constantly cycled to different places in the stereo field.
SPS [ X ]
This parameter sets the amount of Spatial Panning and how the split frequencies are moved about the stereo field. At the [MIN]
position all audio frequencies are locked together and are panned as one. As the encoder is rotated clockwise the audio signal will
become increasingly split into high, mid and low frequency elements until, at the centre position, the separation will be at its maximum.
This '2-Way' setting of SPS shifts two frequency bands from left to right whilst holding the third in a central position (see [2-WAY
SPLIT] section above). As the encoder is rotated further clockwise towards the [MAX] the movement of the split frequency bands
increasingly changes, the three bands now starting to 'chase' each other in a left, right, centre, left, right, centre... pattern (or
opposite direction) on each triggered pulse until, at the [MAX] end-stop position the Spatial Panning effect will be at it's maximum.
NOTE: There is no SUB-MENU function for the PANNER effect.
2-WAY SPLIT [ Y ]
This parameter sets the configuration of 2-Way Spacial Panning. When the [Y] encoder is in the start-up position the MID frequency
band will be held in a central position with the *low and high *frequencies panning from left to right in opposing directions.
As the encoder is rotated in an anti-clockwise direction the configuration will change so that the HIGH frequency band is now held in
a central position with the *low and mid *frequencies panning from left to right in opposing directions.
As the encoder is rotated in a clockwise direction the configuration will change so that the LOW frequency band is held in a central
position with the *mid and high *frequencies panning from left to right in opposing directions.
