Z-Studio 4Ch Amplifier version 1.1

A solid foundation: a 4-channel amplifier that carefully brings out the character of sound.

【Z-Studio 4Ch Amplifier version 1.1|A 4-Channel Power Amplifier That Brings Out Music Naturally】

If you’d like your car audio to do more than just get flashy—and instead enjoy the expression of the recorded music as naturally as possible, then this is for you.
Z-Studio 4Ch Amplifier version 1.1 is a 4-channel power amplifier designed to reproduce even subtle nuances carefully, without adding excessive coloration. Dry sounds stay dry, and sounds with moisture retain their atmosphere.

In the power supply section—the foundation of the sound—the design uses eight high-speed switching diodes, a high-current filter choke, four high-capacity 22,000µF storage capacitors made by Mundorf, and eight secondary storage capacitors of 4,700µF. The configuration is aimed at powerful playback while firmly supporting both the musical attack and fine variations.

The driver stage employs discrete op-amps built with transistors and FETs. In the input stage, carefully selected components related to sound quality are used, such as precision resistors from Caddock Electronics (USA), the KAISEI coupling capacitors from Audio Note (UK), and Mundorf’s MCap EVO.

Not only does it deliver great sound, but the transparent acrylic top panel—through which you can view the beautiful internal circuit boards and components—is another standout feature of this amplifier. Along with the digital monitor placed on the circuit board, the design is made to let you enjoy the very structure that creates the sound, rather than hiding its functions.

An amplifier’s performance is not determined by its standalone specs alone. The way it sounds can vary even with the same amp, depending on the combination with speakers and a subwoofer, the routing of power and signal lines, the installation method, and the final adjustments inside the vehicle. If it were me, I would first review your current system and the music you usually listen to, and then think together about whether this amplifier’s strengths can be leveraged in your setup.

Z-Studio 4Ch Amplifier version 1.1 is made to order.
