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 environ- ments.
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.
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 MC-1 Digital Controller Installation 1 Controls and Indicators The Front Panel 1. POWER Alternately puts the MC-1 into and out of standby. Turn- ing the MC-1 off with this but- ton (or with the remote) deac- tivates the unit while leaving power to the signal process- ing circuitry to keep it at opti- mum operating temperature.
Lexicon 2 Installation The Rear Panel CAUTION: Never make or break any connections to the MC-1 with the rear-panel power ON. Make sure any associated amplifiers are turned off before turning this master power switch on or off. 1 AUDIO INPUTS 8 stereo analog audio inputs switched with corresponding video inputs and fed to the Monitor outputs.

9 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 RCA- type connector. Note that an S-Video input will be output on both the composite and S-Video outputs.
Lexicon 10 Installation 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.
11 MC-1 Digital Controller S ystem Configuration 2 Restore Factory Defaults Although the MC-1 memory is cleared before it leaves the factory, it is good practice to restore the factory defaults with the following procedure before system configuration.
Lexicon 12 System Configuration 20 100 1k 10k (Hz) (dB) 9.0000 7.0000 5.0000 3.0000 1.0000 -1.000 -3.000 -5.000 -7.000 -9.000 20k Tilt The Tilt parameter can be thought of as a straight line that pivots on a fulcrum at 1kHz to correct the overall tonal balance of source material.
13 MC-1 Digital Controller S ystem Configuration DISPLAY ADJUST MENU ON-SCREEN DISPLAY FRONT PANEL DISPLAY To adjust brightness, use SELECT to highlight BRIGHTNESS, and ▲ or ▼ to set display brightness for the room's lighting conditions. Press DONE twice to return to the main menu.
Lexicon 14 System Configuration Video Input Selection and the On-Screen Display When using the Video Monitor output with the On-Screen Dis- play, the MC-1 automatically puts up a blue or grey background when no video signal is present.
15 MC-1 Digital Controller S ystem Configuration Input Configuration The MC-1 has eight inputs, each of which can be associated with any of the eight video and eight digital audio inputs. Selecting Input Configu- ration from the Setup menu displays a sub-menu which lists these inputs and allows you to select them individually for adjustment.
Lexicon 16 System Configuration The input level meters are displayed when you select the GAIN parameter for an active input which has been selected in the Setup menu. Input Level Meters When GAIN is selected, two on-screen horizontal bar meters display peak incoming signal level.
17 MC-1 Digital Controller S ystem Configuration The MC-1 can also be set up to automatically switch to an appropriate effect whenever PCM, AC-3 or DTS encoded material is detected at the input.
Lexicon 18 System Configuration * As the MC-1 is in AUTOMATIC mode, there may be a brief burst of noise before normal playback begins. The MC-1 V-DISC input is selected. A movie encoded in Dolby Surround is put in the laser disc player and starts to play.
19 MC-1 Digital Controller S ystem Configuration PCM Only If PCM ONLY is selected as the FX FORMAT for a given input, only PCM effects in the MC-1 can be used. When the MC-1 receives a signal which is not PCM encoded, it will mute and display "NO PCM AUDIO.
Lexicon 20 System Configuration NOTE: S-Video input signals will be output on both the composite and S- Video jacks. However, if you are only connecting to the monitor via the S- Video output, composite video input sources will not be displayed.
21 MC-1 Digital Controller S ystem Configuration Record/Zone 2 The MC-1 is designed to be the control center of any system. As such, there are separate outputs for easy integration of external recording devices as well as an additional “zone” in multi-room installations.
Lexicon 22 System Configuration LED and redirects the current main zone input to the Record/Zone 2 outputs. From Standby, turns the unit on, selects the last used Zone 2 input, turns Zone 2 volume on to the value selected in the OUTPUT LEVELS menu and engages full mute in the main zone.
23 MC-1 Digital Controller S ystem Configuration Front L/R Select LARGE for full-range front speakers to deliver full frequency response to the front left and right outputs. Selecting SMALL activates a 12dB per octave highpass filter and automatically routes low fre- quency information to the subwoofer output.
Lexicon 24 System Configuration Center Systems that utilize a full-range center speaker should select LARGE to direct center information to the center output with a full frequency response. Select SMALL for installations where the center speaker is smaller than the left and right front speakers.
25 MC-1 Digital Controller S ystem Configuration 10 100 50 20 1k 500 200 dBr Hz +1.000 0.0 -1.000 -2.000 -3.000 -4.000 -5.000 -6.000 -7.000 -8.000 -9.000 -10.00 -11.00 -12.00 -13.00 -14.00 -15.00 -16.00 -17.00 -18.00 Subwoofer Frequency Response The low pass filter attenuates high frequencies at 24dB per octave.
Lexicon 26 System Configuration Select INTERNAL NOISE TEST or EXTERNAL NOISE TEST from the Output Levels menu. The INTERNAL NOISE TEST disables any EQ functions, centers the Balance and Fader controls, and sets the system volume to +00dB.
27 MC-1 Digital Controller S ystem Configuration The MC-1 provides a Subwoofer Peak Limiter that prevents the subwoofer signal level from exceeding a preset value. The limit is factory preset to a level of +15dB. This setting can be changed within the limiter’s operating range of -5dB to +35dB, with -5dB providing maximum limiting.
Lexicon 28 System Configuration Setting Listener Position The Listener Position menu is used for setting the surround and center delays and calibrating the Panorama effect.
29 MC-1 Digital Controller S ystem Configuration Once you have entered the distance to the nearest speaker, the MC-1 will automatically calculate the maximum allowable distance. The display will show all of the speakers, each with a default distance setting equal to your nearest speaker.
Lexicon 30 System Configuration When calibrating right, if your left ear is in the silent band, the speaker angle is correct. If the two silent bands are too close, lower the Speaker Angle; if they are too far apart, raise the Speaker Angle.
31 MC-1 Digital Controller S ystem Configuration L/R Balance This control allows you to adjust the left/right balance of the front, side and rear main outputs. This control can also be accessed on the remote by pressing and holding the Shift button and using DONE to move to the left, and SELECT to move to the right.
Lexicon 32 System Configuration Customization After you have calibrated and customized the MC-1, there are two additional steps recommended to safeguard the settings. First, docu- ment your adjustments using the worksheet at the end of this manual. Second, consider locking the settings so that they cannot be inadvert- ently changed.
33 MC-1 Digital Controller S ystem Configuration Using MC-1 Effects When EFFECT ADJUST is selected from the Main menu, the on-screen display shows a list of parameters specific to the current effect, as well as the current value of each parameter. (The front panel display shows one parameter at a time).
Lexicon 34 System Configuration Restoring the original parameter values of an Effect The RESTORE PARAMETERS function allows you restore the cur- rently selected Effect to its factory preset state. When you select this function, you will be prompted to reconsider erasing your changes.
35 MC-1 Digital Controller PCM Effects and Parameters The PCM Effects are compatible with two-channel input signals (analog or digital). Panorama Panorama extracts the natural ambience from recorded music and moves it outward from the speakers, producing greater width and depth of image and a feeling of enhanced spaciousness.
36 Lexicon PCM Effects and Parameters Church The Church Effect uses a reverberation algorithm, which differs from ambience in that it does not simulate the reflections of specific halls, but emphasizes rich, smooth reverberant decay in small and medium spaces.
37 MC-1 Digital Controller PCM Effects and Parameters Party The Party effect allows unprocessed stereo signals to be played over all speakers for background music or for maximum acoustical output of the system.
38 Lexicon PCM Effects and Parameters Music Logic Music Logic is a surround effect developed specifically for music listening. It makes full use of additional loudspeakers placed at the center, sides and rear of the room and provides a slight amount of steering for the front channels.
39 MC-1 Digital Controller PCM Effects and Parameters TV Matrix The TV Matrix effect provides surround effects for television viewing of monaural, stereo, and stereo synthesized programs. Parameter Initial Value Range AUTO AZIMUTH ON ON/OFF VOCAL ENHANCE +3.
40 Lexicon PCM Effects and Parameters PCM Effect Parameters 5 SPEAKER ENHANCE simulates 7 speaker playback through a 5 speaker system, providing a heightened sense of spaciousness and envelopment without extra speakers.
41 MC-1 Digital Controller PCM Effects and Parameters speakers are used for bass enhancement, the effectiveness is improved with speakers capable of reproducing reproducing low frequencies (LARGE). Using speakers that are not capable of producing low frequencies (<80Hz) may cause damage to them.
42 Lexicon PCM Effects and Parameters LOW FREQ WIDTH allows you to apply low-frequency spatial correc- tion to the signal. Positive values of LOW FREQ Width indicate that the difference signal (L-R) has additional energy below 500Hz, while the sum (L+R) has correspondingly less.
43 MC-1 Digital Controller PCM Effects and Parameters ROLLOFF mimics the absorption of the air in the hall and, typically, should begin with a low frequency to simulate large spaces.
44 Lexicon PCM Effects and Parameters SURROUND ROLLOFF allows the high frequencies of the surround channels to be attenuated with the same detection circuitry as that described for the Soundstage control. The attenuation is quite attractive on many music and broadcast sources which were not mixed for surround.
45 MC-1 Digital Controller AC-3 Effects and Parameters AC-3 Effects are compatible with Dolby Digital input signals. Any AC-3- capable software and/or source components should be labeled with a badge, similar to the one on the MC-1 front panel.
46 Lexicon AC-3 Effects and Parameters Parameter Initial Value Range AC-3 STATUS (display only — not user adjustable) COMPRESSION OFF AUTO, ON, OFF RE-EQUALIZER OFF ON, OFF BASS ENHANCE OFF ON, OFF REAR DLY OFFSET 5ms 0-20ms SIDE LEVEL +00dB OFF, -30dB to +05dB REAR LEVEL +00dB OFF, -30dB to +05dB LFE MIX LEVEL +0.
47 MC-1 Digital Controller AC-3 Effects and Parameters 5.1 Logic 7 5.1 Logic 7 combines all the features of Dolby Digital AC-3 with enhancements by Lexicon and LucasFilm.
48 Lexicon AC-3 Effects and Parameters AC-3 Effect Parameters AC-3 STATUS displays the current status of incoming AC-3 data. The displayed items are not user adjustable. BASS ENHANCE derives stereo bass to provide low frequencies that are noticeably less localizable and more spacious in the playback room.
49 MC-1 Digital Controller AC-3 Effects and Parameters LFE MIX LEVEL allows separate level attenuation of the LFE channel, which is ultimately mixed to the subwoofer output. As the bass from as many as five other channels is added to the LFE, it can significantly raise subwoofer output levels — and create the risk of damage to a system.
50 Lexicon AC-3 Effects and Parameters VOCAL ENHANCE boosts dialog in the center channel. By targeting specific frequencies, it can boost only dialog, without raising the entire center channel level (which would alter the output balance achieved during calibration).
51 MC-1 Digital Controller DTS Effects and Parameters Parameter Initial Value Range CENTER MIX 16 0-30 SURROUND MIX +2dB -5 to +5dB CENTER DLY SAMPLES +0 -127 to +127 MASTER LEVEL +5dB -5dB to +5dB LFE MIX LEVEL +0.
52 Lexicon DTS Effects and Parameters DTS Logic 7 DTS Logic 7 combines all the features of DTS Digital with enhance- ments by Lexicon and LucasFilm. This effect uses Logic 7 matrix technology to enhance the steering between the side speakers and the rear speakers, so sounds intended to come from behind the listener actually do come from behind.
53 MC-1 Digital Controller DTS Effects and Parameters Parameter Initial Value Range SURROUND EX ON ON, OFF RE-EQUALIZER ON ON, OFF LFE MIX LEVEL +0.0dB -20.0dB to 0.0dB SUBWOOFER LVL +00dB OFF, -30dB to +05dB CUSTOM DTS THX (Including Surround EX) This Effect provides THX 5.
54 Lexicon DTS Effects and Parameters RE-EQUALIZER equalizes the left, center, and right channel outputs to match the overall frequency balance of the original recording. Without this re-equalization, many films and some television programs will sound too bright.
55 MC-1 Digital Controller Troubleshooting If you encounter a problem, please review the items in the following checklist. Also be sure to thoroughly check all other connected compo- nents such as speakers, receiver/amplifier/preamp, VCR, TV, CD player, etc.
