Features The PAHT series features high-level drivers and rugged components and is designed for high-performance applications. It is covered with a black-carpeted finish that will stand up to years of tour duty. The piezo tweeters produce crystal clear highs and will add that special sparkle to your sound system. The PLHR4M adds a compression driver that complements the piezo drivers in producing the high range frequencies and extends the frequency response down to 1 kHz. The integrated passive crossover network is assembled using quality components and functions as a high pass filter. 2 Connections The PAHT speakers have "Quick Connect" speaker terminals, which accommodate wire leads. 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, altering the sound. To avoid this, you may have to use a delay processor to align the sound from the speakers. 3 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 Distorted Sound: Check if the amplifier is overdriven. Make sure you are not exceeding the RMS rating of your speaker. Specifications !" # !/ -* $ % 8 !9 ! &8 ' :8 # -/ * +& " ( ' , - ' . !0 0$ -0 0$ 12 . 3 4 $ 5 # * 8 19 ( # &1 ' -/ * . / :8!
