LIVE! CALIBRATION
LIVE! (Lexicon Intelligent Variable Environment) is a proprietary mode
designed to transform the way your listening room sounds. LIVE! uses
a combination of microphones and digital signal processing (DSP) to
enhance the room acoustics and create the illusion of a larger, more
reverberant listening space. Use LIVE! to create a pleasing environment
to practice or perform with a musical instrument, or to create a livelier
ambience for any social activity. LIVE! CALIBRATION must be
completed before using any of the LIVE! modes.
Notes:
You should run automatic calibration before running LIVE! CALIBRATION.
See page 3-35 for instructions on running an automatic calibration.
Any changes to the LEVELS CALIBRATION or CROSSOVER SETUP in the
SPEAKER SETUP menu will cause LIVE! to become uncalibrated.
Pressing the remote control 7/5 button will cause LIVE! to become uncalibrated.
LIVE! requires 2 microphones, available in a kit from your authorized
Lexicon dealer. (If you already own the Lexicon 4-microphone kit,
there is no need to purchase the 2-microphone kit) These microphones
should be permanently mounted in the listening room. Performing
LIVE! CALIBRATION with any microphones other than those in the kit
can produce undesirable results.
To achieve the proper LIVE! effect your system should be configured
with a minimum of 4 speakers (Front L/R, and either side L/R or Rear
L/R). If no subwoofer is present, the crossover setting of the Front L/R
speakers should be set to FULL.
Proper microphone placement, both during calibration and when
running LIVE!, is essential to achieving the desired results. Suggested
microphone placement instructions and illustrations are included in
this section.
The location of the sound source (piano, guitar, voices, etc.) is not
critical. LIVE! will compensate for sounds that are closer to one micro-
phone or another.
CONNECTING THE MICROPHONES
MC-12 Rear Panel
CAUTION!
• The Lexicon microphones require careful handling. Dropping
or otherwise physically abusing the microphones can cause
calibration errors or irreparable damage to the microphone.
• The microphone wires also require careful handling. Do not
sharply bend the wires or place objects on them.
1. Make sure the MC-12 is powered off or in standby mode.
2. Connect the Lexicon microphones to the microphone input 1 and
2 connectors on the MC-12 rear panel shown above. Connector 1
is for the left microphone, connector 2 is for the right. Microphones
connected to inputs 3 and 4 will be ignored during LIVE! calibration
and operation. Make sure each microphone cable plug is fully
inserted for a solid connection.
During the microphone check, the microphones will be
referred to as 1 and 2 based on the input connector to which
the microphone is connected. You should label the micro-
phones for troubleshooting purposes.
3. Power on the MC-12 or deactivate standby mode.
