SONIFEX Headphone Volume Control, Passive, XLR Input - Jac

This product allows the connection of a stereo balanced line input via 2 x female XLRs and creates a headphone output, with level control. It is transformer balanced, and can be used with any headphones above 150? impedance. The transformer ratio of 2:1 ensures that any headphone load presented at the output is reflected through to the input at a 1:4 ratio (hence a 150? set of headphones looks like 600? at the input, a suitable load for most good quality line output stages).
