SR-1 Owner’s Manual

with common metric hardware on the underside of the upper cabinet. The hardware and required tools are supplied with each cabinet. Please retain the packing materials and supplied tools.

Customer will need to install the “Tilt Bar” and the “Nameplate” and 3 feet. Like the larger bottom cabinet the feet on the upper cabinet have “no-mar” washers between the aluminum hardware and the cabinet finish. To preserve the wood finish on the cabinet, please install these washers. Once this hardware has been installed you may invert the smaller box, such that the top cabinet is now setting upright on a secure surface. Once upright, lift and remove the outer and inner box, foam top tray and foam sock. You may now place the top cabinet upon the bass cabinet.

When stacking the small cabinet atop the large cabinet it is suggested that this be done with the assistance of a second person. One person should lift the upper cabinet and a second person should direct and guide the upper cabinet so that the feet of the small upper cabinet fit directly into the sockets on top of the large cabinet without damaging the finish on any of the pieces.

The Upper and Lower speaker cabinet each have input connectors and it is strongly suggested that the customer bi-wire the speakers with wire of their choice. Speaker wire is a very personal choice, please discuss cable options with your dealer if you do not already own cables that you favor. Pass Laboratories has included a set of jumper cables to allow temporary operation of the speakers with a single run of speaker cable. Extended listening sessions with SR-1 favor bi-wiring or bi-amping. For those so inclined you are also free to bi-amp with dedicated amplifiers allowing the freedom to select separate amplifiers for woofer and tweeter.

On the large, lower cabinets the two pairs of speaker binding posts are in parallel with one another. When wiring with a single pair of speaker cables the lower pair are intended for the run back to the power-amplifier and the upper pair are intended for the jumpers that will connect the power amplifier supplying the lower cabinet to the input connectors of the upper cabinet.
