The N7000 is generally used as a "secondary" network in a three-way setup, connected to the high-frequency output of a primary network like the www.cieri.net jbl n7000 schematic

| Rail | Nominal Voltage | Typical Converter | Regulation | |------|----------------|-------------------|------------| | | +48 V (±2 V) | Isolated fly‑back (primary 12 V, secondary 48 V) | Voltage‑feedback (error amp + TL431) | | –48 V | –48 V | Symmetrical to +48 V using a dual‑output converter or a separate buck stage from +48 V. | | +5 V | +5 V | Synchronous buck (e.g., LM2675) for MCU, DSP, and logic. | | +3.3 V | +3.3 V | LDO regulator for low‑noise analog front‑end. | | +12 V (optional) | +12 V | Small buck for LED drivers & ancillary circuits. | For enthusiasts on sites like Lansing Heritage ,
