37, 38 Record Bus Outputs
The Evolution Two is equipped with one balanced record bus output with XLR
connectors and one single-ended record bus output with RCA connectors. Use
the record bus outputs to record a input signal other than the signal playing on
the main outputs. For more information, see Play and Record, on page 30.
39, 40 Main Outputs

Remote Connections on the Back Panel
42 RC-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.
43 RS-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.
44 12 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
