Awesome quality manual. You really saved my bacon with this one. Was looking for some specific information with regards to my "new" vintage VCR that didn't come with the owners manual. This site is truely a goldmine of available manuals. The quality of the scans are top notch.
Thank-you so much for this awesome manual. If you're looking for this Sony SL-HF400 owners manual, this is the one you NEED to buy. Definitely worth the money.
The manual was made available promptly. I is a clean scan of the original. I had no problem downloading it. The scan was well centered and cleanly formatted. It is as good a product as can be had without being the original document.
Received downlink in less then 8 hours, Item was in good copy condition, and told me how to program the clock timer. The price was very resonable, and the process was very automated and was GREAT to work with.
I was very pleased with the manual I got for my amateur (ham) radio. Without it I could not figure out how to input and/or change the P/L setting on my radio. It drove me nuts as the radio was essentially useless. That all changed when my manual came. Then it took only minutes and I was done. Now my radio works fine. This is an exceptionally good resource as it's a very easy and user friendly download. Thank you very much! Dziękujemy za!

� 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.
