This paper presents the value and need for quality Technical Publications in the Electric and Electronic Industry. Technical publications in Electric and Electronic Industry include a wide variety of documents such as user guides, online help, reference guides, administration guides, standard operating procedures, installation manuals, troubleshooting guides, release notes, quick reference guides, research reports, and product demos. The electric and electronic industry has experienced enormous changes in the last few decades, and the pace of its evolution is increasing. This industry has grown because of government's thrust on it and also due to overall economic growth.

300W Subwoofer Power Amplifier (Updated) Rod Elliott (ESP) Share | Please Note: PCBs are available for this project. Click the image for details. Introduction There are some important updates to this project, as shown below. Recent testing has shown that with the new ON Semi transistors it is possible to obtain a lot more power than previously. The original design was very conservative, and was initially intended to use 2SA1492 and 2SC3856 transistors (rated at 130W) - with 200W (or 230W) devices, some of the original comments and warnings have been amended to suit. Updates 30 Jul 2003 - OnSemi has just released a new range of transistors, designed specifically for audio applications. These new transistors have been tested in the P68, and give excellent results. As a result, all previous recommendations for output transistors are superseded, and the new transistors should be used.

Wiring Loudspeakers in Series and Parallel David Harrison, Model Solutions of Canada Ltd. This article explains how to wire loudspeakers in series and parallel to achieve higher power handling capacity. The specification for our SFX6 sound modules calls for a loudspeaker with an 8Ohms impedance. The power rating of the loudspeaker(s) must be chosen to handle the full power output capability of the sound module on the chosen supply voltage. What does 8 Ohms mean? The 8Ohms refers to the loudspeaker’s electrical impedance. Impedance is a term similar to resistance, but contains additional elements of inductance and/or capacitance. To simplify the discussion here we will assume the loudspeakers’ impedance is resistive across its operating frequency range. This is a gross simplification but to go beyond that is outside the scope of this article. The SFX6 modules are optimized for an 8 Ohm loudspeaker. Since I = V /R where V is voltage, I is current and R is resistance (or impedance), and P = V2/R, where P = power, if you increase the speaker’s impedance to say 16 Ohms, the current will half and the audio output power will also half, given the same voltage.
