Sonifex CM-HP Headphone Volume Control provides the connection of a stereo balanced line input and creates a headphone output, with level control. It is transformer balanced, and can be used with any headphones above 150Ω 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 150Ω set of headphones looks like 600Ω at the input, a suitable load for most good quality line output stages).
