Fosi Audio ZP3 Balanced Preamplifier with 2 RCA Inputs and 1 XLR Subwoofer for Stereo and Home Audio Preamplifier with HPF Filter and Tone Japanese

[Home Audio Control Hub] This hub supports 3 inputs and 3 outputs, allowing you to connect up to 3 audio devices. The included remote control allows for one-touch input switching and volume adjustment. Manage your home audio system freely and conveniently. 【Diverse Connectivity】With RCA1/RCA2/XLR inputs and RCA/XLR/sub-out outputs, the ZP3 allows for easy integration of multiple devices. It supports balanced XLR input and output for clearer sound quality. Furthermore, it supports signal conversion between RCA and XLR, ensuring high compatibility. 【Audiophile-Grade Components】This system uses high-quality parts such as ELNA capacitors, Omron relays, NJR NJU72315 volume ICs, and gold-plated RCA terminals. These components reduce noise and distortion, resulting in superior clarity and high-fidelity sound quality. [Variable High-Pass Filter] With three HPF settings, it cuts low-frequency signals from the RCA/XLR output, sending only mid-high frequencies to the main speakers. Since the low frequencies are output from the SUB-OUT, clarity, sound detail, and overall balance are improved. 【Flexible Sound Quality Adjustment Function】Equipped with bass/treble controls (with bypass function) and L/R balance knobs, you can adjust the sound quality to your liking. Furthermore, it features a volume memory function that stores the volume settings for each input source, creating a smarter and more comfortable listening environment. Precautions when using the ZP3: When connecting the ZP3 for the first time, turn the volume knob counterclockwise 3-4 times to the minimum volume. This is to prevent damage to the speakers or adverse effects on hearing, as the initial volume may be set high. The ZP3 remembers the volume level for each input. When using a new input (RCA1, RCA2, XLR, etc.) for the first time, it is recommended to lower the volume before playback. *Does the volume knob control the subwoofer output? Yes, the volume knob also affects the subwoofer volume. *Why aren't the treble and bass knobs responding? Bypass mode may be enabled. In this mode, the signal bypasses the tone circuit and is output directly, so treble and bass adjustments are disabled.
