Basic Preamplifier Operation

The KRC-HRhas the flexibility of a remote controlled device but does not require special attention in order to perform simple functions. The KRC-HRwill

function much like. other KRELLpreamplifiers. The unit can be operated from the front panel controls or via the remote control. All functions available on the

front panel can also be accomplished from the KRC-HRremote control. This provides the ability to sit in your favorite listening position while controlling all system start-up preamplifier functions.

1.Press the Mute button on the KRC-HR.

2.Turn the volume control fully counterclockwise to the OFF position.

3.Turn the power amplifier ON.

4.Choose a listening source and select that input by pushing the

corresponding input button on the KRC-HR.

5.Start play of the source.

6.Turn the volume control clockwise until you reach a comfortable listening level.

7.When changing sources, return to the Mute position and/or lower the volume. This insures that the next source you play will not be potentially damaging to your system with a high output level.

THEATER THROUGHPUT

The $4 input of the KRC-HRcan be set to operate as a unity gain stage. This removes the KRC-HRvolume control from the signal path. Volume control is

then transferred from the KRC-HRto an A/V surround processor connected to

the $4 input. This feature greatly simplifies the installation of a surround- sound processor into a high performance audio/video surround system.

If the Theater-Throughput option is activated, select S-4 when your home

theater/surround system will be used. In this mode, all control of volume is performed by the A/V surround processor connected to that input. Specifically, Level, Balance and Gain are disabled on the KRC-HRfor the S-4 input only

when the Theater-Throughput is engaged. Mute and Tape (monitor input) will function normally.

KRC-HR specifications
