I was impressed with the quality of service (frequent e-mails to let you know the status of your order), and the speed at which the download became available. The manual was a life saver and was not easy to track down. Thank you for such an excellent service.

the manual was just what i wanted it had all the revelent information required to operate the hifi .Iwould use any manual i downloaded for any item which needs a manual
;
Die gewünschte Bedienungsanleitung wurde vereinbarungsgemäß in deutsch bereitgestellt. Sie ist gut lesbar. Kein Kauderwelsch.
Danke für den Service.

GOOD SERVICE MANUAL GOT ALL THE INFO. THAT I NEEDED..
;
Excellent product and service. I bought a second-hand Casio CPS-60 keyboard which had no manual. Packed full of features which I had no idea how to operate . . .
Google search found this site (and others with the same manual for sale for $8.99!)
I bought the manual and within an hour the download was available. Quality of the scanned images is good - very clear - and the PDF has been created with the pages in the correct order.
I would definitely use this site again.
Connecting Your Subwoofer to Your Amplifier JBL GTO Series
JBL GTO Series subwoofers are available in two different con�gurations: as a single 2-ohm voice coil or as dual 2-ohm voice coils. Depending on the ampli�ers you are using, you may use either single-voice coil or dual-voice coil subwoofers in singles or multiples to maximize the power available from your ampli�ers. 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, consider the following rules: 1. Don�t mix different subwoofer or enclosure types in the same system (use all single-coil woofers or all dual-coil woofers). 2. You may connect the coils of a dual-voice coil woofer in series, but we recommend that you avoid connecting separate woofers in series. The ampli�erdamping 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. Therefore, connecting separate 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 dual-voice coil woofer connected 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 can be calculated using the formula: Impedance = 1 1 + 1 + 1 ... w w w

where w is the nominal impedance of the woofer. 2. The total system impedance of voice coils (or woofers) in series can be calculated using the formula: Impedance = w1 + w2 + w3 . . . The diagrams at right show parallel and series speaker connections.
