EFNOTE PRO 503 Power Electronic Drum Kit is a professional acoustic-design electronic drum system for stage, studio, worship, production, and streaming workflows where playability and isolated console routing matter equally.
A 5-shell, 5-cymbal professional electronic drum system with the EFD-PRO module and stage box, 12 balanced XLR bus outputs, and flexible multichannel routing.
Overview
The EFNOTE PRO 503 combines full-size or compact acoustic-style mesh shells, broad cymbal sensing, the EFD-PRO touchscreen module, and a separate stage-box base. It gives the drummer a natural playing surface while providing engineers with repeatable balanced outputs, USB multitracking, remote control, and deep bus processing.

Playing Response and Acoustic Presentation
Multi-sensor mesh shells support the head, rim, and side-rim articulations listed for each component. EFNOTE cymbals provide broad 360-degree playing and choke response, while the two-piece optical hi-hat tracks open, closed, and transitional movement. Acoustic-style shell dimensions give both the player and audience a familiar visual scale.
Stage Outputs, Monitoring, and Recording
The EFD-PRO stage box supplies 12 balanced XLR bus outputs for direct connection to a stage snake or console. Sixteen internal buses, per-bus filtering and EQ, compression on buses 1-6, separate monitor inputs, 12-channel USB audio output, two-channel USB return, and USB MIDI support touring, worship, studio, and broadcast routing without a separate multichannel drum interface.
