2-Way Passive XLR RCA Audio Isolator – Pro Noise Filter | VIBE
2-Way Passive XLR RCA Audio Isolator – Pro Noise Filter | VIBE
VIBE 2-Way Passive Audio Isolator – XLR, RCA & 6.5mm | Professional Noise Filter
Eliminate unwanted hum and electrical interference from your audio setup with the VIBE Multi-functional 2-Way Passive Audio Isolator. Engineered for live broadcast, studio recording, DJ rigs, and multimedia applications, this professional-grade isolator physically separates two audio systems to ensure clean, stable signal transmission — no power supply required.
Whether you're connecting a mixer to speakers, a computer to a PA system, or a microphone to broadcast equipment, this isolator handles it all. It supports XLR, 6.5mm TRS, and RCA inputs and outputs, making it one of the most versatile passive audio isolators available.
Key Features
- Dual-Channel Isolation: Independently isolates two audio channels simultaneously for a fully clean signal path.
- Universal Connectivity: Supports XLR + 6.5mm + RCA input and output — compatible with balanced and unbalanced signals.
- Balanced/Unbalanced Conversion: Convert unbalanced (RCA) signals to balanced (XLR) output and vice versa with ease.
- Common Ground Switch: Each channel features an individual common ground / non-common ground toggle for flexible grounding configurations.
- Passive Design: No power needed — completely passive operation for zero added noise from a power source.
- High Isolation Voltage: Rated up to 1500V AC isolation voltage (AC 50/60Hz), protecting your equipment from damaging potential differences.
- Wide Frequency Response: 20Hz – 25kHz (±<0.2dB ref 1kHz) for full-spectrum audio fidelity.
- Ultra-Low Signal Loss: Standard insertion loss of <0.7dB (ref 1kHz, 1Vrms).
- CE Certified: Meets CE certification standards.

Frequently Asked Questions
Q: Does the passive audio isolator require any power to operate?
A: No. The VIBE 2-Way Passive Audio Isolator is entirely passive, meaning it requires no external power supply or batteries. It operates purely through transformer-based isolation, making it ideal for simple, reliable setups with no added noise from a power source.
Q: Can this audio isolator convert between balanced and unbalanced signals?
A: Yes. This isolator supports both balanced-to-balanced and unbalanced-to-balanced signal conversion. You can input an unbalanced RCA signal and output a balanced XLR signal, or run balanced signals straight through — making it highly flexible for professional audio configurations.
Q: What types of connectors does this audio isolator support?
A: The VIBE Audio Isolator supports XLR (male and female), 6.5mm TRS (male and female), and RCA (female) connectors on both input and output sides, giving you maximum compatibility across professional and consumer audio equipment.
Q: What is the purpose of the common ground / non-common ground switch?
A: Each channel has its own common ground toggle. This allows you to configure grounding independently per channel, preventing ground loops — a common cause of hum and buzz in audio systems — while maintaining complete electrical isolation between connected devices.
