Low frequency filter circuit:
Under the premise of ensuring the sound quality of the original record, the extremely low frequency signal is effectively filtered to prevent large-diameter speakers from oscillating due to feedback.
High, medium and low gain options:
Provides high, medium and low gain adjustment for MC cartridges. The gain can be set to high (65dB), medium (61dB) and low (57dB).
Five-level impedance matching mode:
Provide MC cartridges with 47Ω, 100Ω, 200Ω, 470Ω and 1000Ω input impedance choices, which can be compatible with more specifications of cartridges.
