Applications
Designed to boost the signal of low impedance moving coil cartridges (5 Ω or less), the MC-2RR-H employs a Jensen JT-34K-DX transformer with a 1:37 turns-ratio that adds 31 dB of noise-free gain. This is ideally suited for Ortofon or similar cartridges that are often selected by the most demanding audiophiles. Simply connect the turntable to the MC-2RR-H, the output signal to a standard RIAA phono input on the receiver or preamp and the MC-2RR-H will quietly do the work without adding noise, distortion or artifact.
