Introduction to Programming Rather than playing an entire CD, you may choose to play only certain selections. To do this, you create a “program” (or playlist) and store it in the Nº31.5’s memory. Before using your Nº31.5’s programming features, become familiar with its con- trols and their locations (see Front Panel, Top Panel, CD Transport Assembly, and Remote Control), as well as their basic functions (see Basic Operation).
If you want to play most of a CD, and just “ignore” a few tracks, you may want to Delete Programming use this shortcut: 1. Using the (or the numbered buttons on the Re- next previous mote Control), select the first track you want to eliminate from your program.
Advanced Programming After you have created a few programs as outlined in the previous section, you may want to review them, add extra tracks to existing programs, or in other ways change the nature of what you have done. The Nº31.5 provides great flexibility in these regards.
Y ou also may erase a selection from a previously saved program.

Setting Options The Nº31.5 gives you the ability to “customize” its operation to suit your particular needs and/or preferences. One of these options pertains exclusively to how the Nº31.5 itself operates: Index 0. The other options address the way in which the Nº31.5 interacts with other Linked Mark Levinson components such as the Nº30.5 Reference Digital Processor and the Nº38S Preamplifier.

Madrigal Communications Link The information needed to take full advantage of the Madrigal Communications Linking system (MCL) falls into two categories: understanding the architecture used, and summarizing which cables are needed between which components. The following technical information is provided as a reference, for custom instal- lations and other applications where a full understanding of the MCL system is important.
The communication required between preamplifier and power amplifier(s) is “Linked amplifiers?” you ask more limited than between other components. In particular, the new 300 series Mark Levinson amplifiers will: • toggle between standby and operate in conjunction with the • when in standby, all of the standby indicator LEDs (sources, •...
Having cleared up (we hope) the conceptual difficulty with how Linking works Which Cables Go Where? and with the names of the various Link communications ports, we move on to the purely pragmatic: what size cables do I use? Where? The Link system uses standard telephone company modular connectors, similar to the ones used in your telephone or computer modem.

Using the latest software As we add features and functionality to the Link system, we sometimes need to update associated software.
Using Learning Remote Controls The Nº31.5 includes both an infrared receiver and an infrared transmitter. With this capability, it can “teach” a learning remote control any commands that might be needed for remote operation that do not exist on the remote control itself. Specifically, the Nº31.5 can send these additional IR commands from its window, enabling you to teach a learning remote any or all of its front- (or top-) panel commands, as well as some optional special commands that are available...
