Introduction

Definition of Terms

The Full Power Balanced X Series consists of three stereo amplifiers, the Full Power Bal- anced 700cx, 400cx, and 300cx Stereo Power Amplifiers and three monaural amplifiers, the Full Power Balanced 750Mcx, 450Mcx, and 350Mcx Monaural Power Amplifiers. Installa- tion, connection, and operation of all amplifiers in the Full Power Balanced series are identical; however, a pair of Full Power Balanced Monau- ral amplifiers are required for stereo operation.

Full Power Balanced amplifiers can be config- ured to accommodate any sophisticated music or home theater system and can be operated by an optional remote control or through the remote control of other Krell components.

This owner’s reference manual contains impor- tant information on placement, installation, and operation of the Full Power Balanced ampli- fiers. Please read this information carefully. A thorough understanding of these details will help ensure satisfactory operation and long life for your Full Power Balanced amplifier and related system components.

Following are the definitions of key terms used in your owner’s reference manual.

CONFIGURATIONS

Krell Link

A method of synchronizing remote control oper- ation for Krell systems that include multiple pre- amplifiers, amplifiers, and associated compo- nents. When Krell Link in/out connections are used, the remote capabilities of the linked com- ponents are controlled from one component, called the control component. The linked com- ponents respond to stand-by and operational mode commands from the control component via MIDI cables.

INPUT AND OUTPUT CONNECTIONs

Balanced

A symmetrical input or output circuit that has equal impedance from both input terminals to a common ground reference point. The industry standard for professional and sound recording installations, balanced connections have 6 dB more gain than single-ended connections and allow the use of long interconnect cables. Bal- anced connections are completely immune to induced noise from the system or the environ- ment.

Krell Current Audio Signal Transmission (CAST)

A proprietary Krell circuit technology for connect- ing analog components, in which the audio waveform is transmitted between components in the current rather than voltage domain. The speed and bandwidth provided by Krell CAST and the CAST circuitry update, Krell CAST II, yield accurate, realistic music reproduction. Krell components connected via CAST and CAST II perform as if they are all part of a single circuit.

Krell Industries is renowned for its high-performance audio equipment, particularly its line of powerful amplifiers that deliver premium sound quality. Among these, the 450Mcx, 700cx, 400cx, 350Mcx, and 750Mcx models stand out for their robust capabilities and advanced technologies, making them popular choices for audiophiles.

The 450Mcx is a class AB power amplifier capable of delivering an impressive 450 watts per channel into 8 ohms. This model is equipped with Krell's signature current-mode topology, which ensures a high level of linearity and a dramatic reduction in distortion. With a heavy-duty construction, including a massive power supply, the 450Mcx offers deep bass response and engaging midrange clarity.

Next in line is the 700cx, which pushes boundaries with 700 watts per channel. This amplifier features Krell's Advanced Power Supply (APS) technology, enabling it to maintain stability even under the most demanding speaker loads. The result is explosive dynamics and captivating detail, delivering a listening experience that is both immersive and exhilarating.

The 400cx is designed for versatility, providing 400 watts per channel in a compact form. This model utilizes Krell's patented CAST technology, which minimizes signal degradation, ensuring that the audio signal retains its integrity from input to output. It is ideal for both home theater and stereo applications, allowing users to enjoy a rich sonic palette.

The 350Mcx, while delivering a powerful 350 watts per channel, is designed with a focus on reliability and heat dissipation. The dual-transformer design and sophisticated thermal management system ensure consistent performance, even during prolonged usage. It embodies Krell's commitment to sound fidelity and performance longevity.

The 750Mcx takes performance to the next level with remarkable output capabilities. This amplifier is built with multiple output devices in a high-current configuration, designed to drive even the most challenging loudspeakers. Its refined circuitry contributes to a soundstage that is both wide and deep, enriching the listening experience.

In addition to these models, Krell also offers the 300cx and the 350Mcx, both designed to cater to a variety of audio preferences and configurations. Each unit is meticulously engineered to deliver ultrasensitive dynamics and a transparency that brings recordings to life.

These Krell amplifiers not only emphasize power and performance, but they also showcase luxurious design and durability. The combination of advanced technologies, such as current mode and APS, ensures that users receive a premium audio experience that stands the test of time. Whether for professional use or high-end home listening, Krell amplifiers are truly an investment in quality sound.
