Fosi Audio LC30 VU Meter Amplifier Speaker Selector
The Fosi Audio LC30 (Model: LC30-B) is a meticulously crafted device specially developed to meet the requests of audiophile fans looking to enhance their home audio system setups. The LC30 functions as an effortless amp/speaker selector or a visually stunning pure VU meter.
Core Functionality and Performance
The LC30 allows users to effortlessly switch between two sets of amplifiers and/or speakers. With two inputs and two outputs, it enables four distinct configurations.
• Switching: It offers one-tap switching between two amplifiers and two speakers, streamlining the process of A/B comparison testing for different components.
• High Power Support: The LC30 supports high power transmission, ensuring strength and clarity in your music. Each channel supports up to a maximum power of 250W @ 4Ω.
• Versatile Compatibility: The LC30 is built to be compatible with a wide range of amplifiers, supporting all mainstream types on the market. Supported amplifier types include BTL, Class A, Class B, Class AB, Class D digital amplifiers, and tube amplifiers, among others.
Vintage Elegance and Display
The LC30 offers a vibrant audio-visual feast through its large dual VU meters.
• Large-Sized VU Meters: The device boasts dual 85 × 45mm VU meters. These provide real-time feedback on the left and right channel signal strength.
• Adjustable Backlight: The VU meter backlight brightness offers five settings for adjustment: 100%, 75%, 50%, 25%, and Off.
• Needles Sensitivity Adjustment: A dedicated knob allows users to adjust the sensitivity of the needles to match various input signal strengths, ensuring the capture of every note's pulse.
Superior Construction and Internal Components
The LC30 is built with superior components and design elements to ensure high-fidelity sound with virtually no impact or loss in sound quality.
• All-Aluminum Alloy Chassis: The device features an exquisite all-aluminum alloy chassis. It utilizes a one-piece CNC-molded and anodically oxidized process, resulting in a sandblasted all-aluminum body. This construction ensures durability and reliability.
• Protective Components: Integrated switching relays and high-quality relays are used for high-power lossless output, creating an unparalleled listening experience.
• No-Load Protection: The device includes built-in 390Ω protective load resistors. These are designed to prevent amplifier no-load conditions, guaranteeing stable operation and potentially extending the amplifier's lifespan.
• Thickened Circuitry: It utilizes thickened copper foils in the circuitry (thickened circuit traces) to minimize power loss during audio transmission.
• Space-Saving Design: The large-sized chassis can accommodate Fosi Audio compact amplifiers on the top, offering versatile configuration options.
• User-Friendly Terminals: The terminal design is oriented upwards/downwards, which simplifies the cable connection process, making connections quick and easy.
Ease of Control
The LC30 prioritizes user experience with simplified controls:
• Operation: Switching between components is made convenient through both front panel buttons and a multifunctional remote control.
• Front Panel Controls: The front panel features three integrated keys for power, brightness adjustment, and speaker/amplifier switching.
• Power Supply: The device requires a DC 5V USB-C power supply voltage.
