The MBL 4006 is a dedicated line-level preamplifier from MBL's Classic line, designed to partner with separate power amplifiers such as the MBL 8006A or 7006. It offers multiple high-level inputs including two CD inputs, XLR, and processor bypass, with both RCA and XLR outputs. It has extremely wide bandwidth from DC to 600 kHz on its inputs, very low noise and distortion (THD typically below 0.0007%), and high channel separation. The 4006 uses high-quality internal construction including monocrystalline OCC copper wiring for resolution and tonal finesse. It draws around 20 VA in a compact chassis approximately 450 x 100 x 410 mm, weighing about 10 kg.
