User manual JBL SAM3VA

[. . . ] This inverted dual-magnet configuration improves magnetic shielding even further, reducing the extraneous magnetic field, and offers increased acoustic output. DEEP-ANODIZED CONE AND DOME MATERIAL: The special deep-anodized aluminum cone and dome material, together with the motor features, helps to reduce midband distortions to very low levels (approximately 50dB to 60dB below the fundamental signal driven at 100dB output). TWO-STAGE PHASE PLUG: The phase plug is a key element in this compression driver. The accuracy of the phase plug geometry is most important to achieve a wide and flat frequency response. The pressure distribution in the phase plug is manipulated by adjustments to the number and width of the slots and even the plug inside streamline is optimized to achieve a coherent pressure front across the operating range at the exit of the phase plug. SYMMETRICAL INDUCTANCE MODULATION (SIM): The flux-stabilizing ring and copper gap ring are also optimized for size and position, to help minimize or eliminate "asymmetrical inductance modulation. " Minimizing this asymmetrical inductance modulation leads to even further distortion reduction and improved vocal clarity. 3 SPEAKER PLACEMENT Positioning your loudspeakers properly is critical in order to achieve the sonic performance of a home theater. [. . . ] 7. 1-Channel system CONNECTING THE SPEAKERS TO THE REST OF YOUR SYSTEM To connect the Synthesis Three Array loudspeakers to the power amplifiers or receiver, use two-conductor insulated speaker wire. We recommend #14 AWG wire as a minimum size. Your JBL dealer can recommend suitable cables. Both the SAM3VA and SAM3HA utilize 5-way binding posts that can accommodate up to #10 AWG stranded wire. PREPARING THE HOOKUP WIRE 1. First determine the distance between your amplifier and the most distant speaker in each group (fronts, surrounds, back surrounds, subwoofers). Now make the hookup wires for all speakers in each group this length, even if one speaker is much closer to your amplifier than the other. This will help maintain proper signal balance. Strip off 3/8" (10mm) of insulation from both ends of each conductor. Twist each set of standard wires into a tightly bunched spiral. Speakers and electronics terminals have corresponding (+) and (­) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (­) terminal, although some electronics manufacturers have adopted the new color-coding standard promulgated by the Consumer Electronics Association. In that case, the positive terminal will be colored to correspond to the channel position, while the negative terminal will be black. It is important to connect all speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and poor imaging. 2 Left Front Right Front Center Left Side Right Side Left Rear Right Rear Ch. 1 Input RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR Ch. 5 RISK OF ELECTRIC SHOCK CAUTION DO NOT OPEN ON 15A 120V 50/60Hz 1800W Ch. 7 AVIS: ~ WARNING: ATTENTION: VOIR LE CAHIER D' INSTRUCTION HAZARDOUS ENERGY, MAKE PROPER SPEAKER CONNECTIONS; SEE OWNERS MANUAL BEFORE USING.
