PASS SR2 Owners Manual Rev 0.
The “SR-2” (second Son Of Rushmore) loudspeaker is Pass Laboratories third entry into the often-confusing world of loudspeakers, a world fraught with claims of new technology and brilliant technological breakthroughs. Pass Laboratories claims no inclusion of special technology in the SR-2, only Nelson Pass’s meticulous attention to detail, a strong commitment to using the finest available parts and the love of experiencing the finest in recorded music in your own environment.
compromise of the Rushmore’s acoustic characteristics as possible. Like Rushmore and the SR-1 the Pass Laboratories SR-2 started with premiere examples of the loudspeaker driver makers art; the highly regarded Nextel series of drivers from Seas of Norway.
then we say sit back and enjoy the “SR-2” Loudspeaker for what it does. If you want to enjoy the equipment we say sit back and enjoy the “SR-2” for all the things it lets you do. Unpacking Your SR-2 system comes double boxed with each cabinet in it’s own pack. Within the double box, each speaker sits in rigid foam top and bottom trays that facilitate unpacking by a single person. We do not suggest that you attempt to separate inner and outer boxes.
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.
need to attach to the positive terminals of the power-amplifier. The negative speaker terminals on both pairs of speakers need to attach to the negative terminals of the amplifier. Maintaining proper signal polarity is critical with all bi-wired speakers. Failure to maintain consistent polarity between the speakers and amplifier will be cause all manner of ills from collapsed and diffuse soundstage to greatly marginalized frequency response.
Diffusion generally is a good thing and excellent listening rooms typically have diffusion in abundance. Great sounding rooms are either large enough or absorptive enough to discourage strong standing waves in the listening area. Good sounding rooms that present a proper spatial image tend to be very symmetrical in layout, left to right. Under these idyllic room conditions speaker placement is frequently a simple task.
Of primary concern was a speaker that would be spectrally balanced throughout the room rather than only in a very narrow and defined “sweet spot”. The SR-2 was specifically built to those parameters. Once the speaker position and cabinet tilt is optimized for apparent tweeter height the listener will need to adjust the level controls for optimal results.
rooms which are otherwise lacking in high frequency and down or counter-clockwise for rooms which tend to sound too bright. If the listening room allows the listener to be directly on axis with the drivers and the room is neutral in character then the most likely setting of this control will be either the mid position or perhaps the clockwise or lower position.
