NEC M-50
Not much survives on the NEC M-50. The clearest record is a short listing in the September 1987 issue of HI-Fi-Stereo-Buyers (p.16). It calls the M-50 a mono power amplifier for surround-sound or subwoofer systems that need adjustable crossover networks. It was rated at 50 watts and listed at $375.
The notable feature in that entry is the pair of filters, high and low, with five settings each. They let you tailor the crossover point to the speaker or subwoofer in use. Beyond that, the archive's sources document no other specifications, production dates, or design details.
Known specifications:
- Mono power amplifier
- Output: 50 W
