Location Considerations

The MC-1 is a highly specialized signal processing computer and

requires special care during installation to ensure optimum perfor-

mance.

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 disconnect-

ing 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.
