JBL Comprehensive Guide to Connecting Your S4800 Speaker

PASSIVE CONNECTION METHOD

The passive method requires one amplifier and one set of wires. Connections are made to the lower terminals (one black, one red). Do not remove the shorting straps. Loosen the lower terminal caps. Connect the positive conductor to the right (red) terminal and the negative conductor to the left (black) terminal (see Figure 10). Refasten the terminal caps.

BI-WIRE CONNECTION METHODS

The bi-wire connection method requires one amplifier and two sets of speaker wires. By removing the shorting straps, connections may be made to the individual net- work sections using four conduc- tors, one for each of the four termi- nals (see Figure 11).

The optimal method of powering the S4800 system is with two amplifiers, one for the low-fre- quency unit and one for the high- frequency unit. Since each amplifi- er drives only one speaker, this method allows the user to select amplifiers with the desired sonic

character for low and high fre- quencies (see Figure 11).

NOTE: When using separate high- and low-frequency amplifiers with dual wires to each speaker, the amplifiers must have exactly the same gain structure, or one of them must have a level control to adjust the gain between the two amplifiers.

Four identical amplifiers (or two dual-channel units) may be used, although specialized low- and high-frequency amplifiers offer clear advantages. A JBL specialist dealer can recommend the amplifi- cation that will best suit individual needs.
