The Prismatic Wall by Electronic Audio Experiments is a sympathetic resonator designed to transform incoming sounds into the vibrations of an illusory array of strings.

Its metallic yet warm timbres range from the subtle harmonic aura of a third bridge to the rich chromatic beatings of a grand piano.

The simulated vibrations form a sustained spectral extension of your instrument, maintaining a tangible physicality despite their surreal overtones.

The resonances are inherently reactive: Playing in tune stimulates specific pitches, while percussive attacks excite all the strings in tandem.

Analog/digital hybrid signal processing (24 bit, variable sample rate) paired with analog filtering and emphasis, for low noise with a colorful character

High headroom analog dry path and mixer

Comprehensive digital control of every function using a 32-bit processor system that seamlessly integrates with the analog signal path.

Performance-friendly expression morphing functionality with intelligent momentary/latching behavior and adjustable rise/fall times

Full MIDI implementation (CCs and presets) for all parameters, analog and digital

16 preset slots: 3 via the front panel, the rest via MIDI

CTRL jack for MIDI, expression, and CV input

Multi-mode, assignable LFO with periodic and random waveforms

Updatable firmware via MIDI Sysex messages

Bypass switching: Electronic bypass with buffered or Trails modes.

Input impedance @ 1kHz: 1MΩ

Output impedance @ 1kHz: 1kΩ

Power: 9VDC, 2.1mm center negative barrel. Current draw is 120mA max.

We recommend a regulated, isolated power supply rated for 200mA minimum to accommodate startup surges. The DC input is protected against reverse polarity and over-voltage up to 24V. Our pedals do not accept batteries.

All Electronic Audio Experiments pedals come with a warranty tied to the original owner.

Tune: adjusts the pitch of the resonators across a four octave range

Mix: wet/dry blend

Drive: sets the signal level driving the resonator, with overload at higher settings

Damping: high frequency decay of the resonators

Decay: overall decay time of the resonators; at its upper range also adds analog feedback to create infinite drones

LFO Rate: LFO speed; modulates Tune by default

LFO Amount: LFO amplitude

Mode Button: selects between four string spacing modes: single w/ harmonic overtones, stacked neutral thirds, stacked fifths, and chromatic

Wave Button: selects the LFO waveform between periodic and random modes. Long press to access the Mod page.

Engage Footswitch: activates the pedal. Long press to toggle trails/standard bypass modes.

Aux Footswitch: the footswitch behavior depends on the Aux button setting. In Morph mode, Aux will jump between two distinct knob settings with intelligent momentary/latching behavior. In Preset mode, Aux will scroll through the first three presets.

Aux Button: determines the behavior of the Aux footswitch. Long press to access alt functions, and press again to return to the panel.
