SECTION SIX

Optional Connections

This section describes three optional connections for the Master Reference Subwoofer.

Krell Link connections (9) allow you to synchronize subwoofer operation with other

Krell components that have Krell Link in and out connectors. The RS-232 port (13)

allows you to connect the subwoofer to a computer-based control system. The 12

VDC (12 V trigger) input and output (10) allow you to integrate the subwoofer into

a system with other components that use a 12 Volt trigger.

Krell Link

Krell Link in/out connectors on the back panel allow you to integrate the Master

Reference Subwoofer into systems that include multiple preamplifiers, amplifiers

and associated components, to synchronize their operation with a remote control.

When the Krell Link in/out connectors are used, the remote capabilities of linked

components are controlled from one component, called the control component.

The linked components respond to stand-by and operational commands from the

control component via MIDI cables.

Notes

The Master Reference Subwoofer cannot be used as the control component.

The Master Reference Subwoofer remote control takes priority over Krell Link commands.

The CAST features of the Master Reference Subwoofer cannot be switched via Krell Link.

Krell Link uses standard five-pin MIDI communication cables, sometimes called MIDI Plus

cables. These MIDI cables can be purchased from your authorized distributor or dealer, or

from an audio supply store.

Connecting Components Through Krell Link

Use one or more five-pin MIDI cables (sometimes called MIDI Plus cables) to create

an active Krell Link with Master Reference Subwoofers.

1. Turn all components off. This ensures components are synchronized when the

MIDI cables are connected.

2. Select the control component. It must be in plain view for proper remote control

operation.
