Madrigal Imaging Mark Levinson No. 29 manual

Balanced normal (non-inverting) operation

If your preamplifier is equipped with a balanced main output, it's best to wire the Nº29 for balanced operation, particularly if long cable lengths are required between the preamplifier and the Nº29. (See Figure 3 for the pin assignments of the Nº29's XLR-type inputs.)

Connect the XLR-type male line-mount connector to the preamplifier, carefully observing pin assignments. (Refer to your preamplifier's operating manual to verify that the pin assignments of its output correspond to the diagram above. If they don't, wire the connector so that the appropriate output pin connects to the equivalent input pin.)

When complete, connect the main outputs of the preamplifier to the left- and right-channel XLR-type inputs on the rear panel of the Nº29. Be sure to remove the shorting strap between Pins 1 and 3 before inserting the output cable connectors.

Note: For proper balanced operation, no connector (pre- shorted or otherwise) should be inserted into the RCA-type inputs on the rear panel of the Nº29.
