3. Setup
3.1 Power Requirements
The Lex V2 pedal requires a 9V DC power supply, providing 300 microamps of current. Use only the included power supply or a compatible isolated power supply to prevent damage.
3.2 Connecting Your Pedal
Connect your instrument to the IN jack. For mono output, use the OUT L jack. For stereo output, connect to both OUT L and OUT R jacks. The pedal supports both mono and stereo input sources via a TRS input switch.

3.3 MIDI and Expression Pedal Connectivity
The EXP/MIDI jack allows for full MIDI control via a TRS 1/4" cable or USB-C. This enables control over various parameters and access to 300 MIDI preset locations. An expression pedal can also be connected here for real-time control of selected parameters.
4. Operating Your Lex V2 Pedal
The Lex V2 offers a comprehensive set of controls to shape your rotary speaker tone. Familiarize yourself with each knob and switch for optimal sound sculpting.

Figure 2: Overview of the Lex V2 pedal's control surface.
4.1 Control Knobs
- SPEED: Adjusts the rotation speed of the simulated rotary speaker.
- MIC DISTANCE: Controls the simulated distance of the microphones from the rotary speaker, affecting stereo width and room ambience.
- HORN LEVEL: Adjusts the output level of the rotating horn, allowing it to cut through the mix or blend more subtly.
- PREAMP DRIVE: Adds grit and harmonic richness, simulating the tube-driven amplifier of a classic rotary speaker.
- VOLUME: Boosts or cuts the overall output level by up to 6dB.
- DRY: Mixes in your dry signal, allowing for parallel processing.

4.2 Switches and Footswitches
- MIC (front/rear): Selects the microphone placement, either in front or behind the simulated cabinet.
- RAMP (slow/med/fast): Controls the acceleration/deceleration rate when switching between slow and fast rotary speeds.
- SLOW/FAST Footswitch: Toggles between slow and fast rotary speeds. Hold down for a gradual rotary brake effect.
- ON Footswitch: Engages or bypasses the effect.
