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.

At the heart of the Master Reference Subwoofer is a custom-engineered driver, designed to handle the demands of high-powered audio. With a large diaphragm and a powerful motor system, this driver can reproduce lower frequencies with remarkable accuracy. The subwoofer utilizes a sophisticated suspension system that allows for greater travel while maintaining linearity, resulting in an impressive dynamic range. This means that whether you're listening to the subtle nuances of a classical piece or the thunderous explosions of an action movie, the Master Reference Subwoofer can handle it all with finesse.

Krell's proprietary technologies further enhance the performance of the Master Reference Subwoofer. The subwoofer features advanced digital signal processing (DSP) that allows for precise tuning and customization of the audio output. This ensures that the subwoofer can adapt to different room acoustics and individual preferences, resulting in optimal sound quality in any environment. Moreover, the Room EQ feature automatically analyzes the listening space and adjusts the output accordingly, providing an incredible level of personalization.

Connectivity options on the Master Reference Subwoofer are diverse and versatile, including XLR and RCA inputs, making it compatible with a wide range of audio systems. The intuitive interface allows users to easily navigate through various settings, making setup and adjustment a breeze.

In summary, the Krell Industries Master Reference Subwoofer showcases the company's commitment to audio excellence through its unmatched construction, innovative driver technology, and advanced digital processing capabilities. For audiophiles seeking a subwoofer that delivers not just deep bass, but also accuracy and control, the Master Reference Subwoofer stands out as a premier choice, elevating any listening experience to new heights.
