Remote Control Options
The Evolution One amplifier is compatible with the remote controls included with
the Krell Evolution Two preamplifier, other Krell preamplifiers or preamplifier/
processors, and it is compatible with the Universal Krell Touch Screen Remote.
Please contact your authorized Krell dealer, distributor, or Krell, if you wish to pur-
chase a separate remote control for the Evolution One amplifier.
The following remote control options are available, for amplifiers installed outside
of the listening area:
RC-5 Remote Control
Each Evolution One amplifier has an RC-5 remote input (18) on the back panel.
The RC-5 remote input accepts a remote command enabling it to switch
between stand-by and operational modes and to switch between CAST and bal-
anced inputs. The RC-5 remote control is used with a third party remote control
system that provides RC5 (IR) data with the carrier intact, via a wired connection.
A stereo tip, ring, sleeve 1/8” mini connector is used in the following configura-
tion: Tip = RC-5 data, Ring = +5 V, Sleeve = GND.
12 Volt Trigger
The Evolution One amplifier has a 12 Volt trigger input/output connection (19) that
sends and receives 12 VDC power on/off (12 V trigger) signals to/from other Krell
components and other devices that incorporate a 12 Volt trigger. Mono 1/8” mini
connectors are utilized with the following configuration: Tip = +12 V, Sleeve = GND.
Notes
When the Evolution One is in the operational mode, the 12 VDC Out 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 Volt trigger.
