DC-1 Digital Controller

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

The DC-1 may be installed on a shelf or in a standard 19" equipment rack, using optional rack-mounting hardware available from Lexicon. Observe the following precautions:

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

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

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

Make sure the DC-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 DC-1 may be placed in a glass-doored cabinet but smoked glass will make the front panel Liquid Crystal Display (LCD) difficult to read and will reduce the sensitivity of the IR receiver.

The DC-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 condi- tioner to protect against under voltage (brownouts) as well as overvoltage conditions.

The DC-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 DC-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 DC-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 DC-1.
