42RC-5 In

Each Evolution Two preamplifier chassis (1) has an RC-5 remote input. The RC-5 remote connector is used with a third party remote control system that provides RC-5 (IR) data with the carrier intact, via a wired connection. A stereo tip, ring, sleeve 1/8” mini connector is used in the following configuration: Tip = RC-5 data, Ring = +5 V, Sleeve = GND.

43RS-232

Each Evolution Two preamplifier chassis (1) has an RS-232 port that receives messages from a computer-based control system, providing integrated control of all preamplifier functions. The RS-232 input uses a 9-pin D-subminiature connector. See the Evolution Two developer's reference, entitled RS-232 Port: Sending Commands and Interpreting Data, for more information.

4412 VDC In/Out (12 V Trigger)

Each Evolution Two preamplifier chassis (1) has 2 outputs that send and one input that receives 12 VDC power on/off (12 V trigger) signals to and from other Krell components and other devices that incorporate a 12 V trigger. This allows you to turn other components on or off, or to and from stand-by, through the remote control. When the Evolution Two is switched to operational mode and is connected to other components through the 12 V trigger, it sends a signal that will switch other components, allowing whole systems or parts of
