Input and Output Connections

CAUTIONS:When making connections to this component or any other, make sure

that the power amplifier is OFF. Make sure all cable terminations are of the highest quality, free from frayed ends, shorts or cold solder joints.

1.Connect the left and right inputs of your source equipment to the inputs on

the KRC-HR. The KRC-HR is equipped with 4 single-ended inputs, 2 balanced capable inputs and 1 single-ended tape input.

2.If the optional phono card is included in your KRC-HR,the turntable's phono leads will be connected to the PH input. If the phono card is not in the

KRC-HR,the PH input remains a standard line-level input.

3.If the Theater-Throughput option is to be used, connect the Main L/R outputs of the A/V surround processor to the $4 input.

When $4 is selected, the KRC-HRwill act as a unity gain throughput, (no

change in level), for this input. All control of level will now be performed by the A/V surround processor.

4.Connect the main output of the KRC-HRto the input of your power amplifier.

The KRC-HR has both balanced outputs via XLR connectors and single- ended outputs via RCAconnectors.

The pin assignment for the XLR inputs and outputs are:

Pin 1 Shield (ground)

Pin 2 Non-inverting (hot)

Pin 3 Inverting

The RCAcenter conductor for each channel is wired in parallel with pin 2. Only

one of the preamp outputs should be connected to an individual amplifier. They can be used simultaneously to drive amplifiers in two different systems.

When connecting inputs or outputs to the KRC-HR, remember that the

balanced connections will have 6dB more gain than the single-ended

connections. When level matching is critical in your installation, keep this specification in mind.
