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.
