PRECAUTION

Single-ended normal (non-inverting) operation

The Nº29 incorporates RCA-type and XLR-type connectors for audio signal input.

The Madrigal-designed RCA-type connectors used for single-ended audio interconnection are a great improvement over ordinary RCA- type connectors. The gold-plated XLR-type connectors employed are of European design, and are made to professional application standards.

For connecting the Nº29 to a preamplifier, we recommend Madrigal Audio Laboratories HPC Interconnect Cable. HPC is available in various lengths, pre-terminated with RCA, XLR, and Camac connectors. For more information, see your Mark Levinson dealer.

The Nº29 can be operated in either single-ended or balanced mode. In each of these modes, the Nº29 can be operated either normally (non-inverting) or inverting.

This manual describes the connections for single-ended normal (non- inverting), single-ended inverting, and balanced normal (non- inverting) operation. If you have questions about these or other methods of signal connection, see your Mark Levinson dealer.

Before making any signal or speaker connections, make sure that the Nº29 is disconnected from your preamplifier and from the AC mains.

Typical audio systems require that the amplifier be of the non-inverting type. This means that the output signal of the amplifier will be in phase with the input signal.

For this type of operation, connect the main outputs of the preamplifier to the appropriate (left and right channel) RCA-type inputs (non-inverting) on the rear panel of the Nº29. Be sure that the shorting strap is inserted into the XLR-type connectors between Pins 1 and 3.
