GFI SYSTEM / DUOPHONY

Duophony is a feature-rich parallel blender. In addition to the common "parallel blending of two signals," you can enjoy presets, MIDI and expression manipulation, and LFOs to change the level of the blend.

■Product Features
Stereo signals (input, output, FX loop)
Parallel and series routing support
Three blend modes: XY mix, Y plus [X], and X plus [Y]
16 presets
Adjustable dry signal level
Loop X can be phase-reversed
Adjustable gain level for each loop
Trails can be turned on or off when bypassed.
Expression and external switches for extended operation
MIDI support
Built-in LFO modulation function to change the blend

Stereo Signal
All Duophony internal signals are stereo compatible.
By using the TRS jacks for inputs, both stereo and mono effects can be connected.
In addition, the L and R outputs are independent terminals.

■ Presets
16 presets can be stored.
Recallable from footswitch, external switch, or MIDI.

Expression control
Expression control of blend ratio and dry signal level.
Maximum and minimum values for Hell and Toe can also be set.
(Compatible with 10KΩ expression pedal)

Modulation Blend
Duophony's original function. Using the built-in LFO, the blend ratio can be varied like a waveform.
This produces an effective effect in which the blend level changes like a wave.
The speed of the modulation can be controlled via expression, tap tempo, or MIDI clock.

Various External Controllers
Expression pedal: Max and min settings for Hell and Toe.
Footswitches: Up to three footswitches can be used. Foot switches can be used for tap tempo and bank up/down.
MIDI IN: Almost all controls can be controlled by MIDI, and MIDI clock is also supported.

Pure signal
100% analog signal. The wide headroom and low noise allow the input signal to be transmitted without any loss or change.
Controls are digitally controlled for seamless operation of a wide range of functions.
