Enter the LA2615, an Analog Surround IC featuring the AViSS 3D Surround Algorithm a proprietary technology by SANYO Electric. This ingenious technology, initially commercialized by Sony under the name “Cinema Space” in their hi-fi audio systems, transforms a stereo image into a virtual surround sound, adding a new dimension to the audio experience.
While I stumbled upon a few applications of LA2615 in service manuals of hi-fi systems by Sony and Sanyo, I noticed a gap in DIY projects featuring this IC. Undeterred, I ordered the IC, which arrived in a compact SMD-type package instead of the one I intended. No matter, I decided to take on the challenge and implemented the circuit on a vero board, employing a bit of a hack to solder the IC.
With ample space in my amplifier cabinet, I easily found the place to locate it. I incorporated the surround sound circuit just between the audio input source and the tone-controller unit.
Notable aspects:

Notable aspects:
- The IC preserves the original tone of the music, ensuring fidelity.
- No unwanted reverb effect is added, providing a natural surround sound experience.
- True surround sound: The direction of the sound is distinctly felt, creating a spacious auditory effect.
