THIS TECHNICAL NOTE APPLIES TO ALL VINTECH X73I'S MADE BEFORE MAY 14, 2010:

There is a "Balanced" designation over both the XLR and 1/4 inch output connectors on the rear panel of our model X73i. While the XLR output connector is in fact balanced, the 1/4 inch output connector is mis-labeled and is actually transformerless and unbalanced. We apologize for any inconvenience this has caused our customers.
