Dual Channel Power:

• Switchable High-Pass or Notch filter per channel for feedback control
• Blend or toggle channels—ideal for mixing pizzicato and arco styles 

Flexible Inputs:

• Works with passive, active, and piezo pickups (10 MΩ impedance)
• Channel A supports Electret pickups; Channel B accepts 48V phantom-powered mics or ¼″ inputs
• Phase Inverter on Channel A to address blending phase issues 

Connectivity & Utility:

• XLR out with speaker sim, ground lift, and FOH-ready signal
