The most prominent new feature of the ELS-01X are the console-sized keyboards. The instrument adds two 61-note keyboards and a full-sized 25-note pedalboard to the STAGEA ELS-01C model. Like the ELX-1m, the ELS-01X has XLR and phono audio-out jacks located at the base of the pedalboard unit. These make it easy to connect the instrument in stage configurations to mixers and external speakers. Since it is a stage model, the instrument does not come standard with built-in amplification and speakers. The speaker unit from the ELS-01C is available as an add-on accessory.
The performance features of the instrument are identical to that of the ELS-01C Custom model STAGEA including 509 built-in voices, 274 built-in rhythms and 300 registration menu music styles. The console layout is the same as the ELS-01C as well with a 6.5 inch touch sensitive TFT color LCD display.
