Bridged operation

When greater power output is desired, the Nº29 may be bridged for monophonic operation into load impedances of at least 2.

Note: Make sure the loudspeaker is rated to handle high power levels. For example, a bridged Nº29 driving an 8loudspeaker is capable of delivering 200W RMS.

For the best bridged performance, we recommend balanced interconnection. If your preamplifier provides balanced output, follow the steps below.

1.For balanced bridged operation, you'll need a special three- ended cable. You may fabricate such a cable according to Figure 10; it's also available through your Mark Levinson dealer as part of a balanced bridging kit.

Note: If fabricating the cable, be sure to use high-quality audio interconnect cable (such as Madrigal HPC).

Connect the bridging cable's female XLR-type connector to the appropriate channel of your preamplifier's balanced main output.
