Input: RCA x2 and XLR Output: RCA, XLR, SUB SNR≥ 115dB; SINAD≥113dB; Crosstalk≤ -130dB Input Voltage Range: AC 110-240V 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 control with bypass function, and L/R balance knobs for personalized adjustment. Volume memory remembers settings for each input source—giving you a smarter, more convenient audio experience tailored to your taste FAQs One channel is louder than the other? Make sure the balance knob is centered on the ZP3 and the input signal is balanced between the two channels. What is the function of the Bypass switch? It toggles tone control on/off. Slide up to bypass bass/treble; slide down to enable them. It doesn’t affect volume. Can I switch between RCA and XLR output? RCA and XLR outputs work at the same time and cannot be switched independently. What is the function of the HPF adjustment? It filters low frequencies, letting highs pass. The ZP3 offers 3 cutoff settings for different output frequency ranges. Why is there no bass or the bass sounds weak? Check if the HPF switch on the bottom is set to 20Hz–20kHz to avoid filtering out low frequencies. Also check if the bass knob is set too low.
