Fosi Audio ZP3 Preamp: A Versatile Control Hub for Home Audio Systems
The Fosi Audio ZP3 Preamp is designed as a Versatile Control Hub for Home Audio Systems, acting as a handy control center for all your audio sources, speakers, and subwoofer. Built on extensive user feedback gathered in August 2023, the ZP3 addresses the need for a preamplifier offering multiple audio inputs. This commitment to user voices has resulted in a product that has already seen significant success, with 2,000 units sold in one week and counting.
Connectivity and Seamless Control (3 In / 3 Out)
The ZP3 features a Triple Input configuration alongside three corresponding output ports, enabling effortless switching.
• Inputs (3): RCA x2, and XLR.
• Outputs (3): RCA, XLR, and Sub-Out.
This comprehensive setup makes it easy to connect up to three audio sources for a truly flexible listening experience. The unit is built with Balanced Transmission and incorporates Balanced Circuitry (XLR balanced input and output) to deliver incredibly good spatial reproduction. It also supports RCA and XLR signal conversion for broader device compatibility.
Versatile Sound Tuning Options
The ZP3 offers extensive control over your sound, incorporating features highly requested by the audio community:
• HPF Adjustment (High-Pass Filter): The ZP3 includes three levels of high-pass filtering: 20Hz-20kHz, 80Hz-20kHz, and 120Hz-20kHz. This feature ensures that only the high-frequency content is sent to the main speakers, which enhances vocal clarity and detail resolution.
• Bass and Treble Control (EQ Adjustment): Personalize your sound with dedicated bass and treble controls. The adjustment ranges are: Treble: ±6dB and Bass: ±12dB, providing customization based on a midpoint reference.
• Bypass: Enjoy a very clean, noise-free listening experience by bypassing the internal tone control circuit.
• Balance Adjustment: Allows users to adjust the volume balance between the left and right channels.
Smart Features and Hardware Integration
Controlling your home audio system is seamless with the ZP3’s advanced features:
• Multi-Function IR Control: A remote control allows you to easily adjust the volume, switch sources, and control the power on/off without leaving your seat. This remote can be used for multiple Fosi Audio products.
• Volume Memory: The unit automatically remembers the volume level for each input source, adjusting to your previous level when switching, making the system smarter and more user-friendly.
• 12V Trigger In/Out: This function enables synchronized on/off with compatible audio setups, such as the ZD3/ZA3, automating system control.
