【Micro Precision Z-Studio 4Ch Amplifier version 1.0｜Discrete Class AB 4-Channel Power Amplifier】

If you’re choosing a power amplifier in search of richer tone and stronger drive, you’ll want to look not only at output power, but also at how the power supply section and the amplification circuitry are built.

Z-Studio 4Ch Amplifier version 1.0 is the first power amplifier from the Micro Precision brand. It’s a discrete-circuit, Class AB 4-channel amplifier—suited for those who want to drive the front and rear speakers with authority, and for anyone who is now ready to assemble their car audio system in earnest.

For the power supply section that supports sound quality, the unit is equipped with four independent toroidal power transformers housed in an aluminum case. It also combines eight high-speed switching diodes to suppress switching noise, a high-current filter choke, and large-capacity storage capacitors from Mundorf.

The driver stage uses a discrete op-amp constructed with transistors and FETs. In the input stage as well, carefully selected components are used in the signal-handling areas, such as precision resistors from Caddock Electronics and Mundorf’s MCap EVO.

An amplifier doesn’t produce the same sound simply by being installed. The final sonic impression changes depending on how you route and supply power, how you handle wiring, how it’s paired with speakers and a DSP, and the adjustments made inside the vehicle. If it were me, I wouldn’t decide the amplifier in isolation—I’d confirm the current system and the sound you want to aim for, then consider which channels to use and how to configure the combination.

Z-Studio 4Ch Amplifier version 1.0 is made to order. You can organize the direction together while looking at your actual vehicle—covering whether it will suit your car model and current audio setup, and even how best to integrate it. If you’d like to add a bit more power and density to your current sound, feel free to get in touch.
