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.

Fast service, document is OK. Thanks! Searched for it long time.

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!
Connecting Your Subwoofer to Your Ampli�er JBL GT Series subwoofers are available in three different con�gurations: single 4-ohm voice coil, single 8-ohm voice coil and dual 4-ohm voice coils. Depending on the ampli�er you are using, you may use either single- or dual-voice-coil subwoofers in singles or multiples to maximize the power available from your ampli�er. To achieve the maximum ampli�er output possible, you should design a speaker system that provides the lowest impedance that your ampli�er is rated to drive safely. When designing a subwoofer system, abide by the following rules: 1. Don�t mix different subwoofer or enclosure types in the same system (use all single-coil 4-ohm woofers, all singlecoil 8-ohm woofers, or all dual-coil woofers).
2. You may connect the coils of a dualvoice-coil woofer in series, but NEVER connect separate woofers in series. Because the ampli�er-damping factor (the ampli�er�s ability to control the motion of the woofer) is expressed as a ratio of terminal impedance (the sum of speaker impedance, wire resistance and the D.C. resistance of any crossover coil connected to the woofer) to ampli�er-output impedance, connecting woofers in series reduces the damping factor of the ampli�er to a value less than 1. This will result in poor transient response. 3. You must use both coils of a dualvoice-coil woofer either in series or in parallel. 4. Most ampli�ers deliver exactly the same amount of power bridged into a 4-ohm load as they do running a 2-ohm stereo load.
To design a subwoofer system that maximizes available ampli�er power, keep the following rules in mind: 1. The total system impedance of woofers in parallel = 1/(1/w1 + 1/w2 + 1/w3...) where w is the nominal impedance of the woofer. 2. The total system impedance of voice coils (or woofers) in series = w1 + w2 + w3... The diagrams below and at right show parallel and series speaker connections. Figure 1. Parallel connection
