Summary
| Description |
English: Marantz SD-60 main audio PCB - NEC uPC1297 Dolby HX Pro IC with associated components. The stereo circuit modulates two AC bias currents and injects them into the recording head via two small push-pull transformers (next to pins 9 and 10). This is a rare example of user-defeatable HX Pro; more often, the circuit is hard-wired into the recording chain and cannot be turned off. |
