This manual is very helpfull to use the Power Supply. All technical information has been available.
For service use the circuit diagrams are very good.
Thanks .

Very comprehensive document which is a must-have for any Satellit 2100 owner whose set up is somewhat intricate. Due to the bad quality of the pictures that are rather dark and a bit blurred I gave 4-star feedback.

The manual was missing 2 pages but when I presented the problem to the company they made every attempt to get the 2 pages to me, when they couldn't they refunded my money. A very pleasing and easy transaction. The manual they provided was the original, it was concise and to the point. I plan to do business with this company again when should the need arise.

The owners manual is very good. all my how to questions were answered in detail.

Irrespectively of this manual exist only germany language, it's useful - although i need some additional task to translate: My english is bad, but usable - but i really dont speak germany. :)
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.
