This product 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 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).

The stereo headphone output uses a stereo 6.35mm jack socket with the following connections:

Pin Type & Connection:

Tip: Left.
Ring: Right.
Screen: Ground.
The headphone level will be at half the level of the incoming signal with the volume control at 100%.

The volume level control sets the output level of the stereo headphone socket and runs logarithmically from zero to the maximum output level.

The stereo analogue input is on a female RJ45 connector with the following standard StudioHub+™pin assignments.

Connection:

1 Left Phase.
2 Left Non-Phase.
3 Right Phase.
4 Ground.
5 N/C.
6 Right Non-Phase.
7 N/C.
8 N/C.
