Home Audio Control Hub

Features 3-in-3-out options for connecting up to three audio sources. Includes a remote control for one-touch input switching and volume adjustment - making it easy to manage your home audio system with freedom.

Versatile Connectivity

Equipped with RCA1/RCA2/XLR inputs and RCA/XLR/Sub-Out outputs, the ZP3 integrates multiple devices with ease. Supports balanced XLR in/out for cleaner sound, plus RCA/XLR signal conversion for maximum compatibility.

Audiophile-Grade Components

Built with premium parts including ELNA capacitors, NJR NJU72315 volume IC, and gold-plated RCA jacks. These components reduce noise and distortion, delivering exceptional clarity and high-fidelity performance.

Adjustable High-Pass Filter

Three-level HPF settings filter low-frequency signals from the RCA/XLR outputs, sending only mids and highs to main speakers while routing bass through the Sub-Out - enhancing clarity, detail, and overall sound balance.

Flexible Sound Customization

Includes bass/treble controls with bypass function, and a L/R balance knob for personalized adjustment. Volume memory remembers settings for each input source - giving you a smarter, more convenient audio experience tailored to your taste.
