TX Underfacer:

• Designed to fit under an angled pedalboard, preserving pedalboard real-estate.
• Handles input, muting, tuning, summing, isolating, and phase correction needs.

Master Mute:

• Mute signal before reaching amps using mute pushbutton on The TX Underfacer.
• Remote control of master mute available with RMT.

Summing:

• Two summing modes: Stereo Sum and Split Sum.
  • Stereo Sum: Left and right inputs merged, sending the same signal to both left and right outputs.
  • Split Sum: Right input ignored, left input split to both left and right outputs.

RMT:

• Control summing mode and master mute with RMT.
  • Hold foot switch for more than 2 seconds to switch sum state.
  • Tap foot switch to mute/un-mute signal.

Ground Lift & Phase Correction:

• Ground lift and phase correction available for running multiple amps.
  • Ground Lift: Eliminate ground loop by lifting ground on one amp.
  • Phase Correction: Correct phase mismatch between amps.

Input:

• Buffered input preserves tone before reaching first pedal.
• Always-on tuner out included.

Specifications:

• Power Requirement: 9V DC center negative plug (100mA)
• Dimensions: 100mm (L) x 118mm (W) x 34mm (H)
• Input Impedance (B. In, L and R inputs): 1 Megohm
• Output Impedance (B. Out, Tuner Out, L and R outputs): 500 ohms
