Description

Sonifex CM-HPR1

TheSonifex CM-HPR1  allows the connection of a stereo balanced line input via a RJ45 with StudioHub+™ pinout and creates a headphone output, with level control. It is transformer balanced, and can be used with any headphones above 150 Ω 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 Ω set of headphones looks like 600 Ω at the input, a suitable load for most good quality line output stages).
