Connections

All connections must be made before the mains adaptor is plugged in and before any amplifier connected is switched on.

Outputs

Two headphone sockets are available to allow a greater range of headphones to be used without need of adaptors. the 3.5mm Jack is standard for 3.5mm terminated phones. The 1/4 inch (6.3mm) jack is standard for 1/4 inch terminated headphones.

Connect the LX2-HPA left and right OUTPUTS to the desired LINE LEVEL (e.g. AUX) inputs of the amplifier system.
