Impedence matching made wasy

Very simple way of impedence matching from connecting keyboards directly to boards & connecting some vintage hi Z equipment to low Z. The only weaknes is where the quarter inch ts gets connected as it will come apart if you are rough but that is the only real concern. I always have a srand by

Superb build quality and works perfectly

The Hosa Technology MIT-129 Hi-Z to Low-Z Microphone Transformer is built like a tank. Worked perfectly out of the box. Sound is pristine, clear and there is zero outside interference from electrical or EMF sources. Connectors are robust and rugged. I expect this to be a trouble free product that will last decades! I wish more things were built this way nowadays. As always, B&H ordering, shipping and handling were top notch, fast and seamless.

will this work transforming a line level coming ...

will this work transforming a line level coming from a mixing board to a Magewell USB Capture HDMI 4K Plus?
Asked by: Reave
No, the Hosa MIT-129 will not convert a line level signal to mic level and the connectors on this adapter are the wrong type. The XLR output on a mixer is male so you would need a female XLR connector on your cable or adapter and the mic input on the Magewell USB Capture HDMI 4K Plus is 3.5mm TRS, not 1/4". Since mixers typically have separate left and right output, you can use a line to mic attenuator cable like the Sescom SES-43DB-MZ2XJ 43 dB Pad DSLR Attenuating Line to Mic Level Cable - 18" (B&H # SES43DBMZ2XJ) which has left and right XLR female connectors to use for the output from the mixer and a 3.5mm TRS male connector for the mic input on the Magewell adapter. Additionally, the Sescom cable is designed specifically to convert line level signal to mic level.
