Set-up and Installation

The Nº38 incorporates both RCA-type and XLR-type connectors for audio signal input and output.

The Madrigal-designed RCA-type connectors used for single-ended audio interconnection are a great improvement over ordinary RCA- type connectors, offering superior contact integrity and mechanical locking when used in conjunction with the Madrigal cable-mounted RCAs. The gold-plated XLR-type connectors used for balanced connections are of Swiss design, and are made to professional application standards.

When connecting the Nº38 to source equipment and power amplifiers, we recommend Madrigal Audio Laboratories HPC Interconnect Cable. HPC is available in various lengths, terminated with RCA, XLR, or Camac connectors. See your Mark Levinson dealer for more information.

Connect the AC cord to the male IEC connector on the center of the bottom panel of the Nº38, then connect the AC cord to the AC mains.

When power is first applied to the Nº38, it will run through an automatic initialization sequence which (among other things) provides a “role- call” of the current input aliases (see “Aliases” on the next page), selects the first alias other than NOT USED or ssp, and sets the volume to OFF.

For optimal sonic performance and longevity, the Nº38 is designed to remain powered at all times (the Standby switch merely mutes the preamplifier’s outputs and turns off the display). There is an initial break-in period of 300 hours before the Nº38 achieves optimum performance.

Note: If AC mains power to the Nº38 is interrupted, the main output will be muted. When power is restored, the initialization sequence described above will restore the preamplifier to normal operation, with the main output muted and the Display indicating OFF. We recommend you allow the circuitry within your various system components to stabilize for 1 to 2 minutes before use after such a power outage.
