Lex faithfully recreates the unique and powerful sound of vintage rotary speakers. This unit was developed based on extensive research into the complex interference that occurs in actual rotary speakers, and the user interface has been significantly revamped to make it easier to perform a variety of settings. Newly added features include a DRY knob that adds dry signal, a VOLUME knob that can boost/cut by +/-6dB, a MIC switch that changes the position of the sound pickup microphone, and a RAMP switch that changes the (rotor) rise speed when switching with the SLOW/FAST switch. With added features that allow for a wide range of expression with simple operation, Lex delivers the ultimate rotary sound with a focus on realism. In addition to a USB-C port for firmware updates and MIDI connection, it also features a TRS MIDI jack for MIDI control, full stereo input and output with mono/stereo switchability, and a premium JFET input. Each model features a new powerful ARM processor, offering higher processing power while reducing power consumption. MIDI clock synchronization allows you to save up to 300 presets. The user interface has been made simpler and easier to use, allowing for intuitive operation while also supporting a wider variety of detailed settings.Features: High-impedance, ultra-low-noise Class A JFET preamp input; Low-impedance stereo output; Expression input for connecting TRS expression pedals, Strymon MiniSwitch, MultiSwitch Plus, and TRS MIDI; USB-C port for MIDI connection and firmware updates Two independent On/Off footswitches.
