Rowin LEF-330 ABY Switch Pedal Passive Signal Splitter Combiner True Bypass Mini Metal Guitar Accessory

Product OverviewRowin LEF-330 ABY is a compact passive line selector stompbox designed for guitar and bass players running dual amplifier setups or switching between two instruments. Fully passive circuit requires no power supply for core signal switching, only DC9V power needed for tri-color LED status lights. It supports two core working modes via side slide toggle: A/B single amp switching, and Y(A&B) parallel dual amp simultaneous output, letting you quickly toggle between amp tones or stack two speaker cabinets for wide stereo stage sound. Scratch-resistant aviation aluminum mini chassis saves critical pedalboard space for touring, studio recording and home practice. Hardwire true bypass circuitry delivers zero tone loss, signal attenuation or unwanted hum when switching channels. Core Key Features2 Working Modes via Slide Toggle SwitchA/B Mode: Footswitch cycles between Amp A (Red LED) and Amp B (Green LED), quick single amp tone switching for live setlistsY(A&B) Mode: Merges both A & B outputs simultaneously (Yellow LED), run two amplifiers at once for wide layered toneFully Passive Signal CircuitNo power required for signal transmission; DC9V center-negative power only activates tri-color status LED indicatorsTri-Color Clear Stage LEDRed = Channel A Active, Green = Channel B Active, Yellow = Both A+B Parallel Output, visible under dim stage lightingBidirectional Signal CompatibilityTwo use directions:① Y = Guitar Input, A/B = Dual Amp Outputs (split one signal to two amps)② A/B = Dual Instrument Inputs, Y = Single Amp Output (swap two guitars/basses quickly)100% Hardwire True BypassUnbroken raw instrument signal path with zero tone coloration, no volume drop during channel switchesDurable Mini Aviation Aluminum HousingUltra-small footprint, lightweight shockproof shell, stable for frequent touring performancesZero Signal Loss Low-Impedance CircuitClean transparent signal transfer without harsh frequency roll-offFull Technical SpecificationsModel: LEF-330 ABY Line SelectorBrand: RowinEffect Type: Passive A/B/Y Signal Splitter & Combiner SwitcherModes: A/B Single Channel Switch / Y(A&B) Dual Parallel OutputCircuit Type: Passive (power only for LED indicator)Jack Ports: 3 × 1/4” Mono Jack (A / B / Y)Input Impedance: 1M OhmsOutput Impedance: 100 OhmsLED Supply: DC 9V, center-negative barrel plug (adapter NOT included; pedal works without power)Material: Aviation Aluminum Alloy Metal ChassisDimensions: 90mm (Depth) × 38mm (Width) × 48mm (Height)Net Weight: 137gPackage Total Weight: 230gCompliance Certifications: FCC VOC, CE EMC/LVD, RoHS CertifiedPackage Includes1 × Rowin LEF-330 ABY Line Selector Switch Pedal1 × English User Manual1.

Product Safety PrecautionsPower SafetyThe pedal operates fully passively without power supply; only use regulated DC 9V center-negative power adapter ≥500mA if you need LED indicator lights. Mismatched voltage or reversed polarity will damage LED circuit. Unplug power supply when unused or during thunderstorms to avoid surge voltage damage.Mechanical Operation SafetyDo not apply heavy force to footswitch, slide toggle or 1/4” audio jacks to prevent internal hardware failure. Unauthorized disassembly of the pedal housing will void the limited 6-month warranty for 95% like-new stock.Cleaning & Storage RulesClean aluminum housing only with dry soft cloth; alcohol, chemical solvents, detergent or abrasive cleaners are strictly forbidden. Store pedals in cool dry indoor space, avoid long-term direct sunlight, humid air, violent vibration and heavy physical impact.Usage Environment WarningDo not operate this ABY switch pedal near water, rainy outdoor environments or high-power magnetic equipment to prevent audio signal distortion and signal dropouts.
