Krell Current Tunnel 1
Introduction
Thank you for your purchase of the Krell Current Tunnel (KCT) CAST Preamplifier. The
KCT features Krell Current Tunnel topology and Krell CAST technology, which work
together to reproduce music with unparalleled sound quality. The KCT has dual zone
capability for listening to music from different input devices at the same time, or listening
to one input device while recording another. Each zone has its own volume and balance
control.
Step-by-step menu options allow you to customize the KCT for ease of use and
seamless integration into your system. Remote control features include a handheld
remote control, which accesses all preamplifier functions as well as the compact disc
functions on Krell compact disc players. The KCT also features Krell Link, RS-232 and
12 VDC (12 Volt trigger) remote control inputs for a variety of system control options. A
menu-driven program remote option allows you to send KCT operating commands to a
learning or programmable remote control.
A front panel display provides feedback on input and zone status, menu function and
selection, and all preamplifier operations.
This owner’s reference manual contains important information on the placement,
installation, and operation of your KCT preamplifier. Please read this information

Definition of Terms
Following are the definitions of key terms used in your owner’s reference manual.
CONFIGURATIONS
Krell Link
A method of synchronizing remote control operation for Krell systems that include
multiple preamplifiers, amplifiers, and associated components. When Krell Link in/out
connections are used, the remote capabilities of the linked components are controlled
from one component, called the control component. The linked components respond to
stand-by and operational mode commands from the control component via MIDI cables.
Theater Throughput
Theater Throughput is a Krell configuration option that allows the signal from a surround
preamp/processor to pass through a Krell preamplifier or integrated amplifier with no
gain, for integrated volume and balance management of Krell home theater systems.
