Introduction

The MC-1 can be thought of as four units in one. At its heart is a reference-quality 8-channel music and film digital audio computer capable of creating or recreating a limitless amount of listening environments. This digital audio computer is mated to an 8-channel, 24-bit Digital-to-Analog converter that rivals the most exotic and costly standalone devices. To harness all of this digital audio power, the MC-1 also includes a built-in line-level preamplifier with 8 analog audio inputs and 8 digital audio inputs for easy integration with multiple source components. Since many of these source components are also capable of outputting high quality video signals, the MC-1 includes a broadcastquality composite and S-video switcher with 8 inputs. The MC-1 also includes a digital output, two RS-232 ports and three digital audio expansion ports. The back panel includes a bare wire block terminal for trigger outputs for easy connection to associated equipment.

The MC-1 is designed to satisfy the most rigorous demands, while retaining simplicity for casual use as well. Using the system can be as simple as pressing an input key and turning the volume up and down. Less-used functions are organized into a simple on-screen menu system and “hidden” buttons on the remote control. Controls are provided to accommodate virtually any system configuration and to allow for varying recording, mixing, and transmission styles, as well as for system control from a second zone, and for control by sophisticated automation systems.

The MC-1 includes NIGHTCLUB, CONCERT HALL, CHURCH, and CATHEDRAL effects for creating an ideal custom listening environment as well as MUSIC LOGIC and MUSIC SURROUND which offer ambience extraction. As these programs use the same Lexicon technology used by the overwhelming majority of professionals for adding ambience to their recordings, you will find playback greatly enhanced by the MC-1, transporting you more deeply into the performance.

The MC-1 also recreates 5.1 channel soundtracks with stunning accuracy, and takes them to a new level of realism with Lexicon’s proprietary Logic 7 technology. These effects allow you to expand 5.1 channel as well as two channel soundtracks for 7.1 and virtual 7.1 channel playback for an increased sense of spaciousness and envelopment.

The MC-1 provides separate effects for listening to 5.1 channel music and down-mixing 5.1 channels to two channels, allowing you to finetune the MC-1 for listening to 5.1 channel music or music videos, as well as recording 5.1 channel sources on 2-channel devices.

The MC-1 can be easily integrated with the various types of loudspeaker systems currently available, including those that are THX certified. By adhering to the rigorous THX Ultra specification, the MC-1 includes THX enhancements for optimizing playback of matrix-encoded film

Lexicon

soundtracks as well as Surround EX for those recorded in the Dolby Digital and DTS discrete formats. These enhancements ensure that film soundtracks, which are typically mixed for the acoustics of large theaters, sound as the filmmakers intended when played back in the relatively small environment of a home theater.

Using the Documentation

Because the MC-1 is designed to be customized for your system and your listening space, the information required for installation is extensive.

The Owner's Manual is designed to assist you in installing, calibrating and operating the MC-1. It should be used in conjunction with the remote control when configuring the system to perform optimally in your environment. This manual was written with the underlying assumption that the installer is familiar with audio/video system installation. An Installation Worksheet is provided at the end of this manual for documentation of the settings arrived at during the calibration procedure.

Glossary of Terms

Although the MC-1 performs very complex signal processing, a great deal of effort has gone into making the technology behind the effects as transparent as possible to the user. To understand the overall organization of the unit, it is helpful to define those few terms which are unique to the MC-1.

AC-3 FX The term AC-3 FX (Dolby Digital Effects) is used to describe all of the effects which are compatible with Dolby Digital input signals. Any AC-3-capable software and/or source components should be labeled with a logo, similar to the one on the MC-1 front panel.

DTS FX The term DTS FX (Digital Surround Effects) is used to describe all of the effects which are compatible with DTS Digital Surround input signals. Any DTS-capable software and/or source components should be labeled with a logo, similar to the one on the MC-1 front panel.

Downmix describes the process of creating a two-channel output from a multichannel (>2) signal. Downmixing is necessary to maintain compatibility between multichannel formats and devices such as Dolby Digital and DTS, and two-channel formats and devices, such as stereo tape decks and VCRs.

Effect An effect is a configuration that determines how the MC-1 will process an input signal. The MC-1 contains 24 effects: Panorama, Nightclub, Concert Hall, Church, Cathedral, Party, 2-Channel, Music Surround, Music Logic, Logic 7, TV Matrix, Pro Logic, THX Cinema, Mono Logic, 5.1 2-Channel, 5.1 Music, 5.1 Logic 7, Dolby Digital, THX 5.1, DTS 2-Channel, DTS Music, DTS Logic 7, DTS Film and DTS THX 5.1.

Parameter Each Effect has a set of parameters (controls) that characterize it. Parameter settings can be changed to customize each Effect for your room and listening taste.

Effect Parameter values are stored/recalled with each Effect. Some examples are: Subwoofer Level and Vocal Enhance

System parameter values are not associated with a particular Effect and their values do not change when a new Effect is loaded. An example is: Speaker Configuration.

PCM FX The term PCM FX (Pulse Code Modulation Effects) is used to describe all of the effects which are compatible with two-channel input signals (analog or digital).

Two-Channel We use the term two-channel rather than "stereo" because a two-channel input can contain monaural, stereo or matrixencoded stereo sound depending on how it was mixed.

Location Considerations

The MC-1 is a highly specialized signal processing computer and requires special care during installation to ensure optimum performance.

The MC-1 may be installed on a shelf or in a standard 19" equipment rack, using an optional rack-mount kit available from Lexicon dealers. Observe the following precautions:

•Select a dry, well-ventilated location out of direct sunlight.

•Do not stack the MC-1 directly above heat-producing equipment such as power amplifiers.

•Avoid placing the MC-1 near unshielded TV or FM antennas, cable TV decoders, or other receivers. The MC-1 may interfere with some FM tuners if it is placed immediately above or below them. Some products, particularly power amplifiers, may cause hum if they are in close proximity.

•Make sure the MC-1 front panel IR receiver window is unobstructed. The remote control must be in line-of-sight to this receiver for proper operation. If line-of-sight is impractical, an infrared remote repeater can be used with the rear panel IR connector. The MC-1 may be placed in a glass-doored cabinet but smoked glass will make the front panel display difficult to read and will reduce the sensitivity of the IR receiver.

AC Connections

The MC-1 is designed to be connected to an uninterrupted AC power line in the same manner as a VCR or a television. We recommend the use of an AC line filter to protect against line surges, or the installation of a line conditioner to protect against under voltage (brownouts) as well as overvoltage conditions.

The MC-1 has a master power switch on the rear panel above the IEC standard AC power receptacle. This switch may be left ON continuously when the unit is in regular use. When the MC-1 will not be used for an extended period of time, or whenever you are connecting or disconnecting any cables to the unit, this switch should be turned OFF.

Connect the power cable to the MC-1, then plug the power cord into a wall outlet or into an unswitched outlet on a surge protector. Be sure that the power cord is firmly seated in the connector on the rear panel of the MC-1.

Wiring Considerations

Audio/Video Cables

There is debate over the audible effects of different types of interconnects. Good engineering practices have minimized the effect that cables might have on the inputs and outputs of the MC-1 — but feel free to evaluate different interconnects in your system. Be conscious, however, of the mechanical stress from repeated insertion and overly tight connectors, and the possibly corrosive nature of some contactenhancing fluids.

Note that the use of standard audio cables for video or digital audio applications may cause signal degradation, and is not recommended. For these connections, please use only cables that are designed for the application — these have different impedance characteristics than cables designed for analog audio applications. Consult your dealer for recommendations.

All cables should be kept as short as possible.

Speaker Connections

Wire Lengths

Length	AWG Size
up to 12 feet	16 gauge
up to 18 feet	14 gauge
up to 29 feet	12 gauge
up to 51 feet	10 gauge

In general, speaker cables should be kept short, and low-impedance wire should be used throughout to assure efficient power transmission and avoid audible distortion. Recommended wire lengths are given in the table below. Although these examples can be used as a general guide, your system manuals should provide detailed information specific to your components.

Audio/Video Connections

Before making any connections, turn off ALL audio and video components, including individual power amplifiers. (Unplug any components that don’t have power switches.)

The MC-1 is designed to function as the control center of the system, selecting inputs and controlling the volume of all speakers in the system. The following diagram shows a system with a tape deck, an AM/FM tuner, a CD player with a coaxial digital audio output, a satellite receiver with an optical digital output, a DVD player and a VHS VCR. This example shows the tape deck and VCR set up for recording and dualzone audio.

Actual system connections will vary widely depending on the components used. Consult your dealer for details on your particular requirements.

MC-1 Connections

Input sources should be connected directly to the MC-1 inputs.

Connect your main stereo amplifier to the MC-1 FRONT outputs. Connect any additional amplifiers to the remaining outputs on the MC-1: side amplifiers to the SIDE outputs, rear amplifiers to the REAR outputs, center-channel amplifier to the CENTER output and the subwoofer amp to the SUBWOOFER output. If you are using di-pole surround speakers, the amplifier driving them should be connected to the MC-1 SIDE outputs.

Whenever possible, connect both analog and digital outputs of digital sources. This enables use of a digital input for the main zone, and the corresponding analog input for the Record/Zone 2 outputs.

8

MC-1 Digital Controller	Installation

Video Connections

The MC-1 has eight composite and S-Video inputs. Connection to an S- Video input will override the composite signal connected via the RCAtype connector. Note that an S-Video input will be output on both the composite and S-Video outputs. Composite input signals will not be output as S-Video.

You can assign any video source to any (or all) of the eight MC-1 inputs via the Input Configuration submenu of the Setup menu. This can be very useful in systems which use a VCR as the tuner for TV viewing, as the video feed from the VCR can be assigned to both the VCR and TV inputs. The VCR's audio signals can be fed to both inputs with Y- connectors. (Do not use Y-connectors on video signals.) This allows the audio and video signals from the VCR to be used for both TV and VCR viewing.

You can also assign any video source to audio-only sources such as an AM/FM tuner, to enjoy music from another source while viewing a video source.

It is important to remember that the impedance characteristics of composite video and digital audio are different from analog audio. You should only use cables specifically designed for video and digital audio. Consult your dealer for recommendations.

Digital Audio Connections

The MC-1 has eight S/PDIF digital audio inputs: five coax via RCA and three optical via TOSLINK™. The digital inputs can be set up to be selected with any (or all) of the eight inputs via the Input Configuration menu. Using the digital inputs will always provide superior performance.

Expansion Port Input Connections

The MC-1 also has three digital audio expansion ports (A, B and C). These coaxial digital audio inputs are capable of accepting stereo PCM signals up to 24-bit/96kHz. Expansion Port A feeds the Left and Right Front channels directly. Expansion Port B feeds the Center and Subwoofer channels directly, and Expansion Port C feeds the Left and Right Surround channels directly.

Note: These inputs are designed to completely bypass all of the digital signal processing of the unit, including the crossovers and effects.

For DVD players that support true 24/96 digital audio outputs, we recommend connecting one DVD digital audio output to Expansion Port A, and another DVD digital audio output to one of the MC-1's eight S/PDIF digital audio inputs.

9

Installation

Lexicon

NOTE: Whenever playback of a 24/96 disc is desired, press 2-CH while holding down the Shift button on the remote control. If you are using SMALL loudspeakers, these inputs will send a full frequency response signal to the outputs, completely bypassing the internal crossovers. Do not use this input with Dolby Digital or DTS signals.

Whenever playback of non-24/96 discs is desired, select the regular input on the MC-1 remote control or front panel.

Digital Output

For digital-to-digital audio recording, the MC-1 also includes a coaxial digital audio output (S/PDIF OUT). Any digital audio input (coaxial or optical) selected for Record or Zone 2 will be sent directly to this output.

NOTE: Analog audio inputs and the Expansion Port inputs are not available at the S/PDIF OUT, and the REC/ZONE 2 option in the Input Configuration menu does not affect the S/PDIF OUT.

"AC-3 Ready" Laser Disc and LD/DVD Players

"AC-3 ready" laser disc and LD/DVD players output Dolby Digital (AC-3) data from laser discs on a separate RCA jack in Radio Frequency (RF) form. To maintain the exceptional performance of the MC-1, an outboard demodulator is required to turn this RF signal back into a digital bitstream. By performing the necessary demodulation outside the MC-1, the potential for RF interference is eliminated. The Lexicon LDD-1 is an excellent example of one such device.
