Once the bottom tray is removed, place the SR-2 speaker cabinet upright in the intended location. Place all packing into the now empty boxes and save for later use.

The SR-2 speaker cabinets each have bi-wire input connectors and it is strongly suggested that the customer bi-wire or bi-amp the speakers with wire of their choice.

Speaker wire is a very personal preference; 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; we strongly suggest dual runs of cable.

During extended listening sessions with the SR-2 product, most listeners sonically favor bi-wiring or bi-amping. For those so inclined you are also free to actively bi-amp with an electronic crossover. Active bi-amping through an electronic crossover such as the Pass Laboratories XVR1 allows ample freedom to select separate amplifiers of disparate gain for woofer and mid-range / tweeter. If you intend to use the electronic crossover option, please contact the factory for suggested crossover settings.

If you are using the preferred method of bi-wiring with two pairs of speaker cables from the power amplifier, then you must remove the supplied jumper wire. Failure to remove the jumper wire when bi- wiring or bi-amping places your amplifiers at risk.

Please keep in mind that the speaker cabinets are polarity sensitive. The positive speaker terminals on both pairs of speakers
