LIVE! CALIBRATION

SETUP 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 3-35for 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

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.
