[. . . ] The largest factor is the physical size of the room. The best way to balance speaker volume is to equip each of the speaker pairs in your system with a Niles volume control. The controls allow you to adjust the volume of each speaker pair individually. [. . . ] The amplifier/speaker connectors on the HPS are removable. If you wish, you may remove the HPS's connectors to facilitate installation see (Figure 3). Strip 3/8" of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends. Insert each wire into the appropriate hole on the connector terminals. Be certain that proper phasing is observed--connect the positive terminals on the HPS to the positive terminals on the amplifier and speakers and the negative terminals on the HPS to the negative terminals on the amplifier and speakers. Re-install the connectors if they were removed. Insert the connector plug into the socket and lock in placeby tightening captive screws on each side of connector. Affix the appropriate label to the recessed area over each on/off selector button. SP EA Wire size is expressed by it's AWG (American Wire Gauge) number. The lower the AWG number, the larger the wire, i. e. , 12 AWG wire is physically larger than 14 AWG.
