GAIN Knob/OVERLOAD LED –
Active ONLY in ENV mode. Controls the sensitivity of
the envelope follower circuit. In ENV mode, an envelope follower controls the phase shifter.
This means that the amplitude of the input signal (your instrument) will determine the
response of the phase shifter. Use the GAIN knob to set the amplitude of the envelope
follower circuit. When the output of the GAIN knob exceeds the maximum amount of phase
shift, the OVERLOAD LED will light up. When you first begin using the ENV setting, we
suggest you turn the GAIN knob up enough so that the OVERLOAD LED briefly lights up on
most of your notes. Please note the OVERLOAD LED may light up when the mode knob is
set to either LED or EXP modes but the envelope follower will not modulate the phase shifter
in these modes.
START Knob
– Sets the START point of the phase shifter’s range.
STOP Knob –
Sets the STOP point of the phase shifter’s range.
A Note on RANGE of modulation
:
The difference between the START and STOP knobs determines the RANGE of modulation.
For maximum RANGE set and START knob to minimum and the STOP knob to maximum,
or vice versa. As you move the START and STOP knobs closer together, you will decrease the
RANGE of modulation. These knobs can also be used together to voice the phase shifter. If
you put both knobs at their minimum positions and turn them simultaneously to the maximum
position, while playing, you will hear the range of sounds available to you.
A Note on DIRECTION of modulation
:
The relative position of the START and STOP knobs also determines the DIRECTION of
modulation. For example, when using the ENV setting, if START is below STOP, when you
pluck a note the phase shifter will jump up from the START position to the STOP position,
then slowly descend back to the START. The opposite will happen if STOP is set below
START.
RATE Knob
– Active in LFO mode only. Controls the speed of modulation by adjusting the
LFO’s rate of oscillation.
Toggle Switch –
In ENV mode the toggle switch determines the speed at which the phase
shifter reacts to your playing. When set to FAST the envelope follower will respond quickly to
your playing. When set to SLOW the envelope follower will respond slowly to your playing.
In LFO mode the toggle switch determines the shape of oscillation. In the UP position the
LFO will produce a triangle wave, giving the phase shifter a smooth modulation from the
START to STOP settings. In the DOWN position the LFO will produce a square wave
oscillation and the phase will jump between the START and the STOP settings.
EXPRESSION PEDAL/EXP MODE –
In EXP mode the phase shifter circuit is controlled
by an expression pedal or control voltage. In this mode, the GAIN and RATE knobs are
inactive. The START and STOP knobs will determine the range of modulation. The ‘toe-up’
position of the expression pedal corresponds to the setting of the START knob. The ‘toe-
down’ position corresponds to the setting of the STOP knob. As you move the expression
pedal from ‘toe-up’ to ‘toe-down’ the phase shifter will move from the START to STOP
settings.
The expression pedal may also be used in ENV mode and in LFO mode. Use the START and
STOP knobs to determine the RANGE of modulation. When the expression pedal is ‘toe-up’
the envelope and LFO will modulate over the full range set by the START and STOP knobs.
As you move the expression pedal to ‘toe-down’ the ENV and LFO RANGE will decrease
towards the point set by the STOP knob.
FOOTSWITCH/STATUS LED
– The footswitch engages/disengages the effect. If the effect
is engaged, the LED will light up. In true-bypass mode, the LED is off.
INPUT Jack –
Connect your instrument’s output to this ¼” mono jack. The input impedance
presented at this jack is 380 kohms.
MAIN OUT Jack –
Connect this ¼” mono jack to your amplifier’s input. The output
impedance presented at this jack is 250 ohms. When using the Stereo Polyphase as a mono
device we recommend you use the MAIN OUT jack.
STEREO OUT Jack
– Connect this ¼” mono jack to your second amplifier’s input. The
output impedance presented at this jack is 250 ohm. When using the Stereo Polyphase as a
stereo device use the STEREO OUT jack for your second channel.
EXP. PEDAL Jack –
Connect this ¼” stereo jack to your expression pedal. The
expression pedal must have a connection for a TRS cable, stereo ¼”. You cannot use
a volume pedal. We recommend the following expression pedals: M-Audio EX-P,
Moog Expression Pedal, and Roland EV-5. You may also connect a Control Voltage,
from a synthesizer for example, to the Exp. Pedal Jack. The Control Voltage must be
between 0V~5V.
