The Bit Buffer is a tiny (2” x 1.5”) buffer that uses an ultra-low distortion, low-noise Burr-Brown op amp. Place it at the beginning of your pedal chain to prevent high-frequency loss (tone suck), or right before a long cable to a pedalboard or amp. The Bit Buffer is always on when power is connected. An internal LED is visible below the power jack. Place before a long chain of true bypass pedals to avoid high-frequency loss Place before a long cable between your pedalboard and amp_Current Stock: SKU: RPL-107 Shipping: Calculated at Checkout Size: 2" x 1.5" x 1.2" Input impedance: 1 MΩ Output impedance: ~ 50 Ω Frequency response (± 3 dB): 20 Hz - 40 kHz Power: 9-18 VDC, center negative Current: 20 mA
