D. Audio Interface (If Supported)

• MIC_P / MIC_N: Differential microphone inputs.
  • Schematic: Includes biasing resistors and coupling capacitors (typically 1µF - 10µF).
• SPK_P / SPK_N: Differential speaker outputs.
  • Schematic: Connected directly to an 8Ω or 16Ω speaker or an external audio amplifier.

5. How to Find or Verify Your Own WLX-896B Schematic

Because the WLX-896B is a generic OEM design, you will not find a single authoritative datasheet. Here is a professional strategy:

1. Search by transistor type instead of board model. If your board uses RD70HVF1, search for "RD70HVF1 amplifier schematic 100W FM". The bias network will be nearly identical.
2. Examine the PCB revision. Look for silk-screened text like "V3.2" or "2023-08". Revision 4.0 boards often replaced bipolar finals (2SC2879) with LDMOS (BLF188). Do not mix schematic versions.
3. Use visual confirmation: The most reliable schematic is one you trace yourself. Use a multimeter in continuity mode. Map out power (Vd), gate (Vgs), and ground planes. Nine times out of ten, the schematic matches the "SE5004L + MRF300" reference design from NXP.

3.1 Power Supply Section

The WLX-896B typically runs on 28V DC (for RD70HVF1 finals) or 48V DC (for LDMOS). The bias voltages are derived via linear regulators:

• +28V/48V rail → Goes directly to drain/collector of final transistors through ferrite beads (FB1, FB2).
• +12V (for driver stage) → Generated by a 7812 regulator from the main rail.
• Bias voltage (Vgs) → Generated by an LM317 adjustable regulator set to ~4.2V for LDMOS or a simple resistive divider for bipolars.

Critical components:

• D1, D2: 1N4007 reverse polarity protection.
• C15, C16: 1000µF/63V electrolytic (main smoothing).
• L5, L6: RF chokes (4-5 turns on T50-2 iron powder core).

4. GitHub and Hackaday

Enthusiasts often upload reverse-engineered schematics. Use search tags: wlx896b, portable cd schematic, sunplus cd schematic.

4) How to read the schematic (step‑by‑step)

1. Start at the mains input: locate fuse, NTC, EMI filter, MOV. Confirm earth/neutral/hot wiring and safety components.
2. Trace to SMPS primary: find PWM controller IC, high‑voltage MOSFET, transformer primary winding, drain/source pins.
3. Identify auxiliary winding or startup resistor/cap for IC supply. Locate standby circuit if present.
4. Follow secondary side: locate rectifiers, filter caps, and per‑rail power distribution. Note output filtering and grouping of ports.
5. Find feedback path: optocoupler and reference (TL431 or integrated feedback in controller). This reveals regulation topology.
6. Locate USB port controllers: resistor networks for D+/D−, dedicated QC/PD chips, or simple auto‑detect ICs.
7. Mark protection circuits: overcurrent sense resistors, current limit circuits, transient suppression, and thermal sensors.
8. Annotate test points, VIN/VOUT nodes, and ground reference (primary vs secondary isolation).
