Input and Output Connections

Connecting the KCT Preamplifier to Your System

See Figure 2 on page 11

Krell recommends using its proprietary Krell CAST system for unparalleled sonic performance between the KCT and other CAST-equipped components.

The KCT also offers conventional balanced operation. The circuitry and connections associated with balanced operation not only can minimize sonic loss but also are immune to induced noise, especially for installations using long cables.

The XLR pin configuration is described below:

Pin 1 Ground

Pin 2 Non-inverting (0°)

Pin 3 Inverting (180°)

Inputs and outputs are located on the KCT back panel. Maintain the correct left/right orientation.

IMPORTANT

Connecting non-CAST components to CAST inputs or outputs can damage your equipment and void your warranty. Do not attempt to alter CAST cable ends or CAST inputs or outputs. It is electrically impossible to convert CAST input/output chassis mount connectors for balanced or single-ended operation.

Follow these steps to connect the KCT preamplifier to your system.

1.Neatly arrange and organize the wiring to and from the KCT and all components. Separate AC wires from audio cables to prevent hum or other unwanted noise from being introduced into the system.

2.Connect the outputs of your source equipment to the appropriate CAST (20), balanced (17), single-ended (18) or tape (19) inputs on the KCT back panel.

3.Connect the appropriate main (22 or 23) and zone 2 (24 or 25) outputs on the KCT back panel to your amplifier(s).

4.Connect the KCT to AC power. Connect the AC power cord to the IEC power connector (31), then plug the AC power cord into the wall. KRELL KCT appears in the front panel display (13), indicating that the preamplifier is initializing. After initializing is complete, the KCT is in the stand-by mode. The red stand-by LED (2) illuminates.
