Feature: 1. GROUND LOOP ISOLATOR: The 2 channel sound signal isolator is designed to eliminate ground loop hum and ensure a non noise sound experience. Effectively eliminate buzzing in sound systems, conference microphones, sound players, and more by isolating ground loops that cause unwanted electrical interference 2. EXCELLENT SOUND QUALITY: With quality components and passive design, ground loop isolators maintain the integrity of the sound signal. L or R input and output connections and switchable common ground provide non distortion transmission and convert unbalanced coaxial signals into balanced lines for long distance transmission. Suitable for radio and TV sound transmission, professional sound performances, laptop to mixer connections, and more 3. NOISELESS BUZZ ELIMINATOR: Experience crystal clear sound reproduction with the ground loop isolator. By effectively isolating the current induced hum caused by the ground loop, power interference and unwanted background noise can be prevented. Protect your equipment from static electricity and excessive voltage differences while maintaining the purity and clarity of your sound signal 4. EASY TO USE AND COMPACT: Ground loop isolators have interfaces for easy plug and play installation. Compact and portable design for easy storage and transportation. Whether you're setting up your sound system, connecting your video system to speakers, or connecting a variety of sound devices, offer easy solutions to improve sound quality 5. TRUSTED AND ROBUST: Made of robust metal materials, ground loop isolators ensure long lasting performance. Robust construction and trusted insulation protect your equipment from strong electric shocks, thereby preventing potential damage. Passive sound isolators deliver consistent, trusted results, allowing you to enjoy uninterrupted, quality sound in any environment Specification: Item Type: 2 Channel Ground Loop Noise Isolator Input Output Impedance: 600Ω(AC impedance) Isolation Voltage: AC0V-1500V 50Hz-60Hz Insulation Resistor: DC1000V 100MΩ Frequency Response: 0-20KHZ(±<0.2dbref) Input Level: +28d Bu(Total Harmonic Distortion<0.5%, 50HZ; Total Harmonic Distortion<0.01%, 1KHz) Loss Attenuation: -0.5DB at 600Ω load Distortion Degree: 0.0025%(+4DBU 1KHZ) Product Size: Approx. 106 x 26 x 32mm / 4.17 x 1.02 x 1.26in .
