పరిచయం
The Radial BigShot ABY is a true passive switcher designed to manage a two-amplifier setup for guitar or bass. This pedal allows users to select between two amplifiers or operate both simultaneously, addressing common issues such as ground loops and phase discrepancies. Its passive, true-bypass design ensures signal integrity, making it a reliable tool for musicians.
కీ ఫీచర్లు

చిత్రం: ముందు భాగం view of the Radial BigShot ABY pedal, showing the footswitches, indicator LEDs, and mini-switches for Output B.
- TOGGLE Footswitch: Switches between Output A and Output B. The corresponding LED (A or B) will illuminate to indicate the active output.
- BOTH Footswitch: Activates both Output A and Output B simultaneously. Both A and B LEDs will illuminate when engaged.
- A LED (Green): Indicates that Output A is active.
- B LED (Red): Indicates that Output B is active.
- GND LIFT Switch (Output B): Lifts the ground connection for Output B to eliminate hum and buzz caused by ground loops.
- 180 POL Switch (Output B): Reverses the phase of the signal on Output B by 180 degrees. This is used to correct phase cancellations when running two ampజీవితకారులు.
- ISO Switch (Output B): Engages an isolation transformer for Output B, providing electrical isolation to further reduce noise and hum.

ఆపరేటింగ్ సూచనలు
మధ్య మారుతోంది Amplifiers (A/B Mode)
To switch between your two connected amplifiers, press the టోగుల్ footswitch. Each press will alternate the active output between OUT-A and OUT-B. The corresponding green (A) or red (B) LED will illuminate to indicate which amplifier is currently active.
Using Both Amplifiers Simultaneously (Y Mode)
To send your instrument's signal to both amplifiers at the same time, press the రెండూ footswitch. Both the green (A) and red (B) LEDs will illuminate, indicating that both outputs are active.
Addressing Noise and Phase Issues (Output B Controls)
- Ground Lift (GND LIFT): If you experience a hum or buzz when both amplifiers are connected, especially when using the 'BOTH' mode, engage the GND లిఫ్ట్ switch for Output B. This can break ground loops that cause unwanted noise.
- Phase Reversal (180 POL): రెండు ఉపయోగించినప్పుడు amplifiers simultaneously, you may encounter a thin or hollow sound due to phase cancellation. Engage the 180 POL switch for Output B to reverse its phase. Listen for a fuller, more robust sound, indicating correct phase alignment.
- Isolation Transformer (ISO): For persistent noise issues, particularly when using two amplifiers with different electrical characteristics, engage the ISO switch for Output B. This activates an internal isolation transformer to electrically separate Output B from the rest of the circuit, further reducing noise.
Experiment with the GND LIFT, 180 POL, and ISO switches on Output B to achieve the cleanest and most harmonically rich sound when using both ampజీవితకారులు.
