Forth Pabx Service Manual mod#There was no clear indication of the crossover frequency between the tweeters and midrange drivers in any- thing we measured or heard, which is actually as it should be. However a poor man s mod to convert Advertisement Forth pabx service manual. The speaker’s specifications state only that its impedance is compatible with amplifiers designed to drive 4- to 8-ohm loads, which is consistent with our measure- ments. There were peaks of 14 ohms at 100 Hz and 10 ohms at 1.4 kHz. The system’s impedance ranged from 4 ohms between 3 and 20 kHz to 16 ohms at 20 kHz. The output plots on-axis and 45 degrees off-axis remained close up to about 10 kHz, and then the curves diverged by about 5 dB at 13 kHz and 15 dB at 20 kHz. Safety information Always follow basic safety precautions when using this product to reduce risk of injury from fire or electric shock. The BP 2000’s horizontal dispersion was typical of speakers with drivers of similar size. Our composite response curve for the BP 2000, combining the close-miked sub- woofer response and the room response, had a 6-dB peak-to-peak variation between 100 and 200 Hz, which would certainly be different (but probably pre- sent to some degree) in any other room. Read all instructions, including this manual and the Power-fin Installation and Operation Manual, before installing.
