systems to be easily coordinated. For more information on customizing the 12 V trigger, see Input Trigger, on page 39. Mono 1/8mini connectors are used in the following configuration: Tip = +12 V, Sleeve = GND.

Notes

When the Evolution Two is in the operational mode, the 12 V trigger provides 12 Volts of DC output. When the component is in the stand-by mode or off, the DC output is 0 Volts.

A minimum of 30 mA is required to operate the 12 V trigger.

Consult the owner's reference of the components used in a custom installation to take full advantage of the remote capabilities of the Evolution Two.

Link Control

45CAN Link

Each Evolution Two preamplifier chassis (1) has 2 RJ-45 link connectors, con- nected in parallel. These are used to operate preamplifier channels in linked mode. For more information, see Connections Using CAN Link, on page 28, Operation Using CAN Link, on page 31, and Link Control, on page 41.

Phono Stage Connector
