FX-Audio LS-01J — 4-Channel RCA Line Splitter & Preamplifier
✨ Overview
The FX-Audio LS-01J is an active 4-way RCA line splitter and preamplifier designed for audio enthusiasts who want to distribute a single stereo RCA source to up to four amplifiers or systems simultaneously. Unlike passive splitters that suffer from impedance-related signal degradation at 4-way splits, the LS-01J uses dedicated op-amp circuitry per channel to maintain full signal integrity across all outputs.
⭐ Key Features
- 🔀 Active 4-Way RCA Split: Distributes one stereo RCA input to four independent outputs without signal degradation or frequency response loss
- 🎚️ Per-Channel Volume & ON/OFF Control: Each of the four output channels has its own independent volume knob and on/off switch for flexible system configuration
- 📶 2-Stage Gain Setting: Choose between 0 dB (unity gain) or +15 dB via a rear-panel switch to accommodate sources with low output levels
- 🔋 High-Quality ±12V Op-Amp Power Supply: Uses a high-speed XL6007 DC-DC converter (400 kHz switching) to boost voltage, then generates a clean ±12V regulated supply via series regulators — delivering smooth, grain-free high-frequency op-amp performance
- 🔌 TL062 Input Buffer Stage: The input stage uses a TL062 op-amp to amplify the signal to a strength capable of driving all four output lines simultaneously
- 🔊 Versatile Use Cases: Build a 2.1ch system, run bi-amp speaker setups, compare multiple amplifiers side by side, or distribute audio to multiple rooms — all from a single source
- 🎛️ Standard RCA Connectivity: Works with any RCA cables you already own — no proprietary connectors required
