About this item

  • 【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.

Frequently Asked Questions

What types of products does Stagevera sell?

Stagevera offers equipment and accessories for stages, theaters, performances, presentations, schools, houses of worship, DJs, and event venues. Our collections include stage lighting, PA speakers, microphones, stands, backstage supplies, presentation equipment, cables, cases, storage, and transport products.

How can I check whether a product is compatible with my equipment?

Review the product description, dimensions, connector type, voltage, power rating, mounting method, supported frequency, and other specifications before ordering. Products that look similar may use different connectors or technical standards. Contact us before purchasing when compatibility remains unclear.

Are cables, stands, adapters, or mounting hardware included?

Included components vary by product. Please check the product page carefully to see what is supplied in the package. Accessories shown in product images may be used for demonstration and may not always be included unless specifically listed.

Can I use the electrical products outside the United States?

Some products may be designed for particular voltage, frequency, plug, or wireless standards. Confirm the electrical specifications and local compatibility before ordering or using the product. A plug adapter alone does not convert voltage or guarantee safe operation.

Do stage lights and audio equipment require professional installation?

Some products can be used in simple portable setups, while overhead lighting, permanent speaker mounts, power distribution, and complex audio systems may require experienced or qualified installation. Always follow the manufacturer’s instructions and applicable venue and safety requirements.

How long will it take for my order to arrive?

Processing and delivery estimates may vary according to the product, destination, carrier, and availability. The estimated delivery information available during checkout or in your order confirmation should be reviewed before completing your purchase.

How can I track my order?

When tracking information becomes available, it will generally be sent to the email address used for the order. Tracking activity may take additional time to appear after a shipping label has been created or the parcel has been transferred to the carrier.

Can I change or cancel an order after placing it?

Contact us as soon as possible after placing your order. We will review the request, but changes and cancellations cannot be guaranteed once processing or shipment has started. Confirm product specifications, quantity, color, and delivery details before submitting the order.

What should I do if my order arrives damaged or incomplete?

Contact us promptly with your order number, a description of the issue, and clear photographs of the product, packaging, shipping label, and received contents. Keep all original packaging while the issue is being reviewed, as additional information may be required.

What is Stagevera’s return policy?
