2. Opsætning
2.1 Strømtilslutning
Connect the included 9V DC power adapter to the 'DC 9V' input jack located on the rear of the pedal. Ensure the power supply meets the specified voltage and polarity requirements (center negative).
2.2 Lydforbindelser
- Input: Connect your instrument (guitar, bass, etc.) to the 'IN' jack on the right side of the pedal.
- Produktion: Connect the 'OUT' jack on the left side of the pedal to your amplifter eller den næste pedal i din signalkæde.
2.3 Bypass Mode Selection
The 2020-2.0 Pedal Tuner offers two bypass modes: True Bypass and Buffered Bypass. Use the 'BUFFER OFF ON' switch on the rear of the pedal to select your preferred mode.
- OFF (True Bypass): When the tuner is disengaged, your instrument's signal passes directly through the pedal without any electronic buffering. This preserves the original tone but may lead to signal degradation over long cable runs or complex pedal chains.
- ON (Buffered Bypass): When the tuner is disengaged, a high-quality buffer circuit maintains signal integrity, preventing tone loss over long cables or through multiple pedals. This is generally recommended for larger pedalboards.
3. Betjening
3.1 Engaging the Tuner
Press the footswitch to engage the tuner. When engaged, the display will activate, and the pedal's output will be muted, allowing for silent tuning during performances.
3.2 Aflæsning af displayet
The large, bright display shows the note being played and indicates whether it is sharp, flat, or in tune. The central bar indicates perfect pitch, while bars to the left indicate flat and bars to the right indicate sharp.
3.3 Kalibrering
The standard calibration (A4) is 440Hz. To adjust the calibration, press and hold the 'PITCH' button. The display will show the current calibration frequency. Use the 'PITCH' button to decrease the frequency and the 'FLAT' button to increase it. The calibration range is 436-445Hz in 1Hz steps. Release the button to set the new calibration.
3.4 Flat Tuning Modes
The tuner supports three flat tuning modes. To cycle through these modes, press the 'FLAT' button. Each press will add a flat symbol (b, bb, bbb) to the display, indicating tuning down by a semitone, two semitones, or three semitones, respectively. Pressing it a fourth time will return to standard tuning.
