SAM1HF, SAM2LF OM.qxp 4/24/07 9:40 AM Page 6 SPEAKER PLACEMENT NOTE: It is extremely important to place the tweeter/mid-bass arrays for each of the center, left and right speakers at the same height. The horn array containing the tweeter in the center channel speaker should be no more than two feet (0.6 meter) higher or lower than those in the left and right speakers. This preserves the “localization integrity” of “sound pans,” in which the sound appears to move from left to center to right.
SAM1HF, SAM2LF OM.qxp 4/24/07 9:40 AM Page 7 SPEAKER PLACEMENT 6.1-CHANNEL SYSTEMS L C R A 6.1-channel system can be thought of as a 5.1-channel system with the addition of a rear center speaker placed midway between the two surround speakers, and further to the rear than the surrounds. It should be placed at the same height as the side surround speakers (see Figure 5). 7.1-CHANNEL SYSTEMS In a 7.1-channel system, two speakers are added for rear fill, in addition to the surround speakers in a 5.
SAM1HF, SAM2LF OM.qxp 4/24/07 9:40 AM Page 8 SAM1HF AND SAM2LF CONFIGURATION AND ASSEMBLY The different configurations of speaker arrays are accomplished by combining one (1) SAM1HF module with at least one (1) and up to four (4) SAM2LF modules. The configuration of your system depends greatly on room size and at what SPL the system will be used. The different array configurations can be used to customize individual speakers for any application in any system.

SAM1HF, SAM2LF OM.qxp 4/24/07 9:40 AM Page 11 CONNECTING THE SPEAKERS TO THE REST OF YOUR SYSTEM To connect the Synthesis 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 SAM1HF and SAM2LF utilize push-style friction binding posts that can accommodate up to #10 AWG stranded wire. PREPARING THE HOOKUP WIRE 1.
