This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
� At the same power levels Infinite Baffle designs (no enclosure, sometimes called �Free-Air�) allow greater cone motion and the power rating of the subwoofer must be reduced to reflect this (see the specifications). At the same power levels Infinite Baffle subwoofer installations will have much longer cone excursion than subwoofers mounted in an enclosure. � Sealed enclosures exert some control over excursion as a result of the air inside the enclosure acting as a spring against the woofer cone motion. Large enclosures typically allow higher excursion than smaller boxes. � Vented and Band-pass enclosures have the lowest excursion as a result of the port tuning effects. However, vented enclosures will allow for high excursion outside the port tuning range. Singletuned Band-pass enclosures provide the lowest overall cone excursion. See the specifications sheet for details on the GTi subwoofer power handling capabilities in different enclosure configurations.
Speaker Connection and Combination
GTi subwoofers are 4 ohms nominal impedance. If you are connecting two speakers in parallel to an amplifier channel, make sure your amplifier will drive a two ohm load. Parallel Wiring

Four woofers can also be wired (as shown below) in parallel/series or series/parallel so that the amplifier will see four ohms nominal impedance. Parallel/Series Wiring

If your amplifier will not drive a two ohm load, we recommend that you connect the two speakers in series to create an 8 ohm load as shown here.
