About this product


Product overview

• Reduces the noise and high-frequency loss caused by connecting unmatched impedance devices
• Works as an XLR to 6.35mm (1/4") adapter
• Switchable impedance, between 600 (low) and 50k (high) ohms, to work with a range of equipment

What does this transformer do?
If you’re looking to connect a low impedance microphone (500 ohms) to a high impedance (50k ohms) electronic equipment such as a mixer, then this matching transformer is what you need. When connecting a low impedance microphone to high impedance equipment with mono aux/line input jacks, you will stumble across a buzzing/humming sound (noise and interference) as well as high frequency loss. By matching the impedance between the microphone and the high impedance device this is all reduced. You can also switch the impedance output, to low (600 ohms) or high (50k ohms), so you can use this as a normal XLR to 6.35mm (1/4") adapter.

Does the item act as a switcher of impedances besides being a converter ?  Do I understand correctly? THANKS.

Will this allow me to convert an XLR lead from my microphone to got into my amplifier/speaker or PC?
Asked by: Alan
It will be suitable for an amp but not directly into a pc because the connection requires a stereo 3.5mm plug.

Hi, can this transformer be used "in reverse" to match an unbalanced mic to a balanced?
