The integrated passive crossover network is assembled using quality components and efficiently directs the frequencies to the proper drivers. Your PASC series speaker has an extremely flexible connection panel. You can also hookup your speaker cabinet using the "Quick Connect" speaker terminals, which accommodate either wire leads or a banana plug. The jacks are wired in Connections 2 parallel, which allows you to daisy chain additional speakers. Make certain that the wires you are using are at least 12 gauge unshielded speaker cable (the lower the number, the thicker the wire). Hooking speakers up in parallel decreases the overall impedance, placing a greater load on the amplifier. Check your amplifier's specifications to ensure that you are not overloading the channel. CAUTION: DO NOT US E MORE THAN ONE JACK AS AN AMPLIFIER INPUT. When using more than one loudspeaker, you have to account for phase alignment. However, when they are far apart, the sound from one speaker may reach the ear a fraction of a second before the other. This will cause certain frequencies to cancel out, resulting in a hollow sound. To avoid this, you may have to use a delay processor to align the sound from the speakers. Maintenance and Safety · Do not expose the speaker to moisture. · This loudspeaker is capable of producing extremely high SPL levels. Use earplugs when necessary. 4 Troubleshooting No Sound: Check connections Try a different speaker cable Check levels on amplifier Confirm amplifier is getting a signal (check signal LED, or use headphone output) Intermittent Output: Check connections Try a different speaker cable Weak Bass: Check the polarity of the speaker connection. Listen with headphones to confirm the amplifier is being sent a good signal. Make sure you are not exceeding the RMS rating of your speaker. Specifications !
