Basic Installation

1.Place the unit on a firm level surface free from excessive dirt or moisture.

The KRC-HRis not particularly hum sensitive, allowing other components to

be placed on or around it. If the optional phono card is installed in the

KRC-HR, some components such as Digital to Analog converters, power supplies or components with motors can induce hum into the phono stage.

2.Place the power supply in a location away from hum sensitive components

such as turntables or phonostages. Connect the male		end	of the	DC power
cable into the computer-type connector on the back	of	the	supply.	DO NOT
PLUG THE POWER SUPPLY INTO THE AC OUTLET AT	THIS TIME.

3.Connect the female end of the DC power cable to the computer-type connector on the back of the KRC-HR.

CAUTION: ALWAYS CONNECT THE DC CABLE TO THE BACK OF THE KRC-HR AND TO THE POWER SUPPLY BEFORE YOU PLUG THE POWER

SUPPLY INTO THE WALL OUTLET. FAILURE TO FOLLOW THE

CONNECTION SEQUENCE WILL CAUSE DAMAGE TO THE KRC-HR.

4. Plug the AC cord into the receptacle on the back of the power supply. Plug the remaining end into the wall ACreceptacle.

NOTE: While the KRC-HR has superb regulation and does not require a

dedicated AC circuit, we strongly advise against any connections through

extension cords or multiple AC adaptors. High quality 15 amp line conditioners or grounded AC strips are acceptable.

5. When the KRC-HR power supply is plugged into the wall AC outlet the preamplifier will go through its power-up sequence:

a. The volume control will automatically rotate to the Off position, fully counterclockwise.

b. The Select section LEDs on the KRC-HRwill remain unlit until an input or function is selected.

c. The Protection relays will open once the monitoring circuits have

determined there are no input or output disturbances. See the PROTECTION CIRCUITRYsection of this manual for more information.

6. The power-up sequence lasts about 15 seconds. Once completed, the KRC-HRcan be operated from the front panel or the remote control.
