IWISTAO HA12016 FM Stereo Decoder Board MPX Composite to L/R Audio for IF Amplifier HiFi DIY
Model No: WHFMDM-HA12016
The HA12016 FM Stereo Decoder PCBA Board is a fully assembled analog FM multiplex decoding module designed for DIY Hi-Fi tuners, vintage receiver restoration, and custom FM radio projects.
Built around the classic Hitachi HA12016 PLL stereo decoder IC, the board accepts a composite FM multiplex signal from an FM discriminator stage and converts it into separate left and right analog audio channels.
Features
- Built around the classic Hitachi HA12016 FM stereo multiplex decoder IC
- PLL-based analog FM stereo decoding
- Accepts standard FM composite MPX signal
- Separate left and right analog audio outputs
- Typical stereo channel separation of approximately 55 dB at 1 kHz
- Typical stereo THD of approximately 0.025% at 1 kHz
- Adjustable 76 kHz VCO
- Adjustable stereo channel separation
- Stereo indicator function supported
- Manual mono control supported
- Fully analog signal path with no DSP or digital processing
- Suitable for traditional 10.7 MHz FM IF + discriminator tuner systems
- Suitable for vintage tuner restoration and DIY Hi-Fi FM projects
Signal Connection
The board is designed to operate after the FM discriminator or detector stage:
FM Front End → 10.7 MHz IF → FM Discriminator → Composite MPX Output → HA12016 Decoder Board → Left / Right Audio Output
The MPX input must contain the complete FM stereo composite signal, including the L+R baseband audio, 19 kHz stereo pilot, and the multiplexed L−R information.
The input should therefore be taken from the composite MPX output before de-emphasis.
Adjustable 76 kHz VCO
The HA12016 uses a traditional PLL stereo decoding architecture with an adjustable internal VCO.
The VCO can be calibrated to approximately 76 kHz for accurate recovery of the 19 kHz pilot and 38 kHz switching reference used in stereo demodulation.
This adjustable design is particularly suitable for vintage Hi-Fi tuner restoration and DIY projects where precise analog alignment is preferred.
Stereo Separation Adjustment
The board provides stereo separation adjustment to minimize left-to-right and right-to-left crosstalk.
With a suitable FM stereo generator or MPX test source, the separation control can be optimized for improved stereo imaging and channel isolation.
Specifications
- Operating Voltage: AC 12 V
- Board Size: 85 × 55 mm
Applications
- DIY FM stereo tuners
- Vintage tuner restoration
- FM receiver repair and upgrade
- Analog Hi-Fi audio projects
- Tube amplifier FM front-end projects
- Laboratory and educational use
- Custom radio equipment
Recommended Output Processing
For optimum audio performance, the left and right outputs may be followed by:
- 19 kHz pilot suppression
- 38 kHz carrier suppression
- 50 µs de-emphasis for many European and Asian FM systems
- 75 µs de-emphasis for North American FM systems
- Audio buffer or line amplifier
- Optional ADC / DSP processing
Power Supply
The board is designed for AC 12 V input.
A suitable low-noise AC transformer supply is recommended. Good grounding and short signal wiring can help reduce hum and interference.
Package Includes
- 1 × HA12016 FM Stereo Decoder PCBA Board
Important Note
This board requires a proper FM composite MPX signal from a discriminator or detector stage.
It cannot directly decode a 10.7 MHz IF signal without a preceding FM discriminator circuit.
For optimum performance, proper VCO alignment and stereo separation adjustment are recommended.
