What Is an Audio Isolation Transformer?
O AFT Single Phase Audio Isolation Transformer 240V to 240V is specifically designed to deliver clean, stable, and noise-free power for high-performance audio systems.
Um audio isolation transformer works by electrically isolating your subwoofer and other audio equipment from the main power grid while maintaining the same 240V output. This separation significantly reduces ground loops, hum, and electromagnetic interference (EMI), ensuring pure and accurate sound reproduction.
Whether you are setting up a home theater system, professional recording studio, ou high-end subwoofer setup, this transformer provides a stable and safe power supply to maximize audio performance.

How to Choose the Right Isolation Transformer
When selecting the best audio isolation transformer for subwoofer setups, consider the following factors:
- Power Rating (VA/Watt):
Match the transformer capacity to your subwoofer’s power consumption, preferably 20-30% higher than the rated wattage. - Impedance Matching:
For professional audio systems, ensure impedance compatibility for minimal distortion. - Noise Suppression Needs:
Choose models with advanced EMI and RFI filtering for recording studios and high-end audiophile setups. - Safety & Certification:
Always select certified transformers (CE, RoHS, ISO) to ensure performance and reliability.
FAQ
Q1: Why do I need an audio isolation transformer for a subwoofer?
A: Subwoofers often pick up ground loop hum and electrical noise from shared power lines. An audio transformer isolation system breaks the direct electrical connection, eliminating interference and improving bass clarity.
Q2: Does a 240V to 240V isolation transformer affect sound quality?
A: Yes, in a positive way. By filtering power noise and stabilizing voltage, it delivers cleaner signals to your subwoofer, resulting in tighter bass, richer detail, and better overall sound quality.
Q3: Can I use one transformer for multiple audio devices?
A: Yes, as long as the total power consumption of your connected devices does not exceed the transformer’s rated capacity. For optimal performance, we recommend using a dedicated transformer for high-powered subwoofers.
