Jeff Rowland Design Group 1 Manuel D’Utilisation
Introduction
Congratulations on your purchase of the Jeff Rowland Design Group Model 1 stereo
amplifier.
amplifier.
Please take a few moments to read this owners manual. Contrary to popular belief, there
is actually quite a bit of useful information in an owners manual. The Model 1 offers
tremendous interconnection flexibility regardless of the preamp used. A thorough
understanding of your amplifier now can save you a lot of anxiety later.
