- 【Dual Channel Design for Versatile Audio Routing】 The IS-3 audio isolator features two independent channels, each equipped with flexible input options: Female 1/4" (TRS) unbalanced, RCA unbalanced, and Female XLR unbalanced. This allows you to connect two instruments or audio sources simultaneously—such as a guitar and bass, or a keyboard and media player—without signal interference, making it ideal for home studios, live performances, and podcast setups. The "THRU" output also lets you send a parallel signal to an amp while routing the main signal to a mixer, preserving your preferred tone.
- 【Professional-Grade Audio Performance】 Engineered for clarity and precision, this DI box delivers exceptional audio quality with a frequency response of 20Hz-20kHz (±0.2dB) and a dynamic range of 128dB—ensuring every detail of your sound (from deep bass to crisp highs) is reproduced accurately. With total harmonic distortion (THD) as low as 0.002% at 1000Hz, it eliminates unwanted noise and distortion, keeping your signal clean even during high-volume performances. The 350:1 input-to-output impedance ratio optimizes signal transfer between instruments (active/passive) and audio gear, preventing signal loss or degradation.
- 【10dB/15dB Pad Switch for High-Output Sources】 Equipped with a dedicated pad switch (down position), the IS-3 lets you attenuate input signals by 10dB or 15dB to handle high-output instruments and devices. This is perfect for active guitars, basses with hot pickups, or media players with strong line-level signals—preventing clipping and ensuring a balanced output to mixers, audio interfaces, or amplifiers. The intuitive switch design makes adjustments quick and easy, even mid-performance, so you can focus on your sound without technical delays.
- 【Ground Lift Switch to Eliminate Hum & Noise】 Say goodbye to annoying ground loop hum! The IS-3’s ground lift switch isolates the chassis ground from the signal ground at the balanced XLR outputs, breaking unwanted ground loops that often occur when connecting multiple audio devices. The default "ground out" position works for most setups, while flipping to "lift" resolves hum issues instantly—no need for extra cables or complex troubleshooting. This feature is a game-changer for recording studios and live stages where clean, noise-free audio is non-negotiable.
- 【Durable Build & Wide Compatibility】 Built to withstand the rigors of regular use, the IS-3 combines a sturdy chassis with high-quality connectors (gold-plated contacts optional, based on product specs) for reliable signal transmission and long-lasting performance. It works seamlessly with all passive/active instruments (guitar, bass, keyboard) and audio sources (media players, turntables, microphones), and outputs to mixers, audio interfaces, amplifiers, or FX chains via RCA unbalanced, 1/4" unbalanced, or Male XLR balanced jacks. Whether you’re a professional musician, home recordist, or audio enthusiast, the IS-3 is a versatile tool that elevates your audio setup.
