Overview

MODEL 50 is Marantz’s pure-analogue stereo integrated for vinyl and line sources — not Model 40n / 60n. Discrete HDAM stages and Current Feedback Class A/B amplification with full analogue I/O.

Specifications

Audio figures prefer the Marantz MODEL 50 EU owner’s manual Specifications. Features / I/O / dimensions from the MODEL 50 information sheet. South Africa uses EU-voltage product (AC 230 V). Infosheet “Frequency Response 5 Hz–10 kHz” is a truncated marketing row and is not used; EU OM value 5 Hz–100 kHz ±3 dB is used. No price or stock.
