[. . . ] Combined with the advanced Directivity Control Waveguide TM ual. After unpacking, place the loudspeaker in its required listening position, taking note of the line of the acoustic axis. The axes of all loudspeakers should converge at ear height at the listening position (see Figures 1 and 2). Connections Before connecting up, ensure that the volume control potentiometer on the front panel is turned fully counter-clockwise to the stand-by setting. Connect the loudspeaker to an earthed mains connection with the supplied mains cable. [. . . ] The controls are "Treble Tilt" and Loudpeaker Mounting Position Flat anechoic response Free standing in a damped room Free standing in a reverberant room Near to a wall In a corner or a cabinet Treble Tilt OFF OFF OFF OFF OFF Bass Tilt OFF OFF -2 dB -6 dB -6 dB Table 1: Suggested tone control settings for differing acoustical environments "Bass Tilt". An acoustic measuring system such as WinMLS or comparable is recommended for analyzing the effects of the adjustments, however, careful listening with suitable test recordings can also lead to good results if a test system is not available. Table 1 above shows some examples of typical settings in various situations. Figure 4 shows the effect of the controls on the anechoic response. Treble Tilt Treble Tilt control (switch 2) attenuates the treble response of the loudspeaker at frequencies above 5 kHz by 2 dB, which can be used for smoothening down an excessively bright sounding system. Bass Tilt Bass Tilt control offers three attenuation levels for the bass response of the loudspeaker below 2 kHz, usually necessary when the loudspeakers are placed near a wall or other room boundaries. The attenuation levels are -2 dB (switch 3 "ON"), -4 dB (switch 4 "ON") and -6 dB (both switches "ON"). The factory setting for all tone controls is "OFF" to give a flat anechoic response. Always start adjustment by setting all switches to "OFF" position. Measure or listen systematically through the different combinations of settings to find the best frequency balance. Mounting considerations Align the loudspeakers correctly Always place the loudspeakers so that their acoustic axes (see figure 1) are aimed towards the listening position. Only vertical placement is preferred, as it minimises acoustical cancellation problems around the crossover frequency. Maintain symmetry Check that the loudspeakers are placed symmetrically and at an equal distance from the listening position. If possible, place the system so that the listening position is on the centerline of the room and the loudspeakers are placed at an equal distance from the centerline. Minimise reflections Acoustic reflections from objects close to the loudspeakers like desks, cabinets, computer monitors etc. can cause unwanted colouration blurring of the sound image. These can be minimised by placing the loudspeaker clear of reflective surfaces. Minimum clearances Sufficient cooling for the amplifier and functioning of the reflex port must be ensured if the loudspeaker is installed in a restricted space such as a cabinet or integrated into a wall structure. The surroundings of the loudspeaker must always be open to the listening room with a minimum clearance of 5 centimeters (2") behind, above and on both sides of the loudspeaker. The space adjacent to the amplifier must either be ventilated or sufficiently large to dissipate heat so that the ambient temperature does not rise above 35 degrees Celsius (95°F) maintain the loudspeaker under safe operating conditions: · Servicing and adjustment must only be performed by qualified service personnel. · Do not use this product with an unearthed mains cable or an unearthed mains connection as this may compromise electrical safety. · Do not expose the loudspeaker to water or moisture.
