1 POSITIONING THE LOUDSPEAKERS • The SR5 frequency response is extremely well maintained off-axis. This creates a wide deep precise sound field which allows great flexibility when planning the layout of your room, seating, loudspeakers, and associated equipment (e.g. TV or video screen). Use the following guidelines to determine the optimum positions for your loudspeakers.
• The wall bracket allows you to adjust the angle of the cabinet to fine-tune the sound field which is especially useful when the SR5 is used as a surround or rear channel loudspeaker or if it is mounted on a ceiling. See figure 4. Figure 4 Figure 5 Figure 6 Figure 7 • Surround/rear loudspeakers should generally be mounted above seated ear level. • Surround (side) loudspeakers should generally be mounted above seated ear level. • Centre channel loudspeaker can be above or below the screen.
2 BRACKET AND CABINET INSTALLATION • Check that all loudspeaker cables have been prepared and installed. See section 3 Cables and Connections. • The cabinet is secured to the bracket with 2 x M6 hex-drive socket cap machine screws, 2 x spring washers and 2 x stainless steel bushes. See figure 8. ALWAYS store these components safely whenever they are removed. • Remove the two screws and washers using the supplied 5mm hex wrench and carefully detach the bracket from the cabinet.
3 CABLES AND CONNECTIONS • Loudspeaker cables can have a noticeable effect on sound quality. Choose good quality low resistance cables with high purity metal conductors and low-loss dielectric (insulation). Ask your dealer for advice on cables to suit your system and budget. • Set amplifier(s) to minimum volume and switch off the power. • Always connect the –ve (usually black) loudspeaker output terminal of the amplifier to the corresponding –ve (Black) terminal on the loudspeaker.
BI-AMPING • IMPORTANT: REMOVE the terminal links and store them safely. • Bi-amping allows two independent audio power amplifier of equal or similar quality to be used for LF and HF signals. The benefits of bi-amping include reduced intermodulation distortion because the low and high frequency signals are amplified independently, and more power reserve and dynamic range because each amplifier has less ‘work’ to do than a corresponding single amplifier.
