If you wish, you may remove the HPS's connectors to facilitate installation see (Figure 3). 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. 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.

Figure 2 Wiring Diagram Playing One Pair of Speakers At a Time 1. Make sure the amplifier or receiver power is OFF and set the volume to minimum. Locate the on/off button on the HPS-4/HPS-6 which corresponds to the speaker pair you wish to play. Set it to the ON position (Engaged).

Turn on the amplifier or receiver and select a source, such as the tuner or CD player. Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. If the sound becomes muddy or distorted, you have reached the limit of your amplifier's volume capability and should quickly reduce the volume to avoid damaging your speakers.
